Answer:
6
Step-by-step explanation:
it's given that x=1
y=-(1)+7
y=-1+7
y=6
Answer:
y = 6
Step-by-step explanation:
Given (1, y ) is on the graph of y = - x + 7
Substitute x = 1 into the equation and evaluate for y
y = - 1 + 7 = 6
Then (1, 6 ) lies on the graph
The Sandberg Institute building in Amsterdam generates revenue by selling advertising space on the exterior of the building. The building is a rectangular prism with dimensions 50 m by 40 m by 75 m. Suppose it costs 1 Euro per month to rent an advertising space of 50 cm2 . Each of the 4 walls of the building is covered with advertisements. How much money will the institute earn in one month?
Answer:
2.7 million euros per month
Step-by-step explanation:
Since the room is a rectangular prism, we find the area of the room without its top and bottom, which is the area of the walls, A. So,
A = 2(lh + wh) = 2h(l + w) where l = length of room = 50 m, w = width of room = 40 m and h = height of room = 75 m
Substituting the values of the variables into A, we have
A = 2h(l + w)
= 2(75 m)(50 m + 40 m)
= 150 m × 90 m
= 13500 m²
= 13500 × 1m²
= 13500 × 10000 cm²
= 135000000 cm²
= 1.35 × 10⁸ cm²
Now, since 50 cm² of space = 1 Euro per month, then 1.35 × 10⁸ cm²
= 1.35 × 10⁸ cm² × 1 Euro per month/50 cm²
= 0.027 × 10⁸ Euro per month
= 2.7 × 10⁶ Euro per month
= 2.7 million euros per month
So, the institute will earn 2.7 million euros per month
The profit earned by a sporting goods outlet is modeled in the graph below, where x is the number of years since the outlet opened. He recorded the profit for the first 10 years since the outlet opened.
Answer:
Step-by-step explanation:
Vertex of the given parabola is (4, 160)
Since, graph of the parabola is increasing between x = 0 to x = 4,
Profit earned will be between t = 0 and t = 4
Therefore, domain represents the number of years.
Since, profit of the outlet (y-values) vary from x = 0 to x = 10
And value of profit varies from 0 to 160 thousand dollars, so the range of the function will be (0, 160)
Range of the function represents the outlet's profit.

Write an inequality and solve.
15.) Sam has $25 and plans on saving $15 a week until he has at least $150. Write an inequality
to represent this scenario then find how long Sam needs to save.
Answer:
25 + 15n ≥ 150
Step-by-step explanation:
The term at least mean the amount saved is greater than or equal to 150
Let the number of weeks he intends to save be n
Amount saved after n weeks without the plan is:
15n
Add plan amount
= 25 + 15n
Add inequality
25 + 15n ≥ 150
Are the following systems equivalent? How do you know?
2x+y= -4 7x+7y=0
5x+6y= 4 4x+2y= -4
Answer:
No, they are not equivalentStep-by-step explanation:
Are the following systems equivalent? How do you know?
For the equation;
2x+y= -4 ... 1
7x+7y=0 ... 2
Let us find the solution of the equation;
From 1;
y = 4 - 2x
Susbtitutw into 2;
7x + 7(4-2x) = 0
7x + 28 - 14x = 0
-7x + 28 = 0
7x = 28
x = 28/7
x = 4
Recall that y = 4-2x
y = 4 - 2(4)
y = 4 - 8
y = -4
The solution is (4, -4)
For the other equations;
5x+6y= 4 ... 1 * 1
4x+2y= -4 ..... 2 * 3
___________________
5x+6y= 4
12x+6y= -12
Subtract
5x-12x = 4 + 12
-7x = 16
x = -16/7
Since the solutions to both simultaneous equations are different, hence the systems of equations are not equivalent.
What is the solution to this equation?
–5(s – 30) = –10
s = –4
s = 8
s = 28
s = 32
Answer:
s = 32
Step-by-step explanation:
-5 (s - 30) = -10
Apply distributive property.
-5s + 150 = -10
We need to get "s" alone. By getting it alone, subtract 150 from both sides.
-5s + 150 - 150 = -10 - 150
-5s = -160
Wait a second, there is still a -5 on the s. We need to get s alone. Divide both sides by -5 to get s alone.
-5/-5s = -160/-5
s = 32
s = 32 is your answer AKA the last one. I hope this helps! Let me know if I got anything wrong or if you need any more help.

A bakery makes small batches of bread daily. Each day, the bakery records the amount of flour used the number of loaves of bread made. All loaves are approximately the same size. The table and graph show the bakery’s data for five days.
write an equation that can be used to model the number of loaves of breast, y that can be made from x pounds flour
Use an equation to predict the number of loaves that can be made from 85 pounds of flour show your work or explain your answer
Answer:
The slope of the line would be the constant of proportionality for the line
shown. The point (35, 49) is really close the line which would make the
constant of proportionality 49/35 = 7/5. The equation of the line would be y =
7/5x. The number of loaves of bread from 85 pounds of flour would be
7/5(85) = 119 loaves.
Step-by-step explanation:
A ratio of the rise to a run, or the rise divided by run, is the slope of the line. It denotes how steep a line would be in the coordinate plane.
Slope calculation:This line's slope would be the proportional constant.This point (35, 49) is extremely near to the lines that would result in the linear constant [tex]\frac{7}{5} = \frac{49}{35}[/tex] , the line's equation is [tex]y = \frac{7}{5x}[/tex]. Using 85 pounds of flour, Calculate the loaves of bread that may be made [tex]\frac{7}{5(85)} = 119[/tex] loaves.Therefore, the equation was used to forecast the number of loaves that could be created from 85 pounds of flour, and the result was 119 loaves.Find out more about the slope here:

Answer:
B. 63
Step-by-step explanation:
5x + 3y = 38
2x+3y=13
y=?
x=?
Answer:
The solution to the system of equations is:
[tex]x=\frac{25}{3},\:y=-\frac{11}{9}[/tex]
Step-by-step explanation:
Given the system of equations
[tex]5x + 3y = 38[/tex]
[tex]2x + 3y = 13[/tex]
solving the system of equations
[tex]\begin{bmatrix}5x+3y=38\\ 2x+3y=13\end{bmatrix}[/tex]
Multiply 5x+3y=38 by 2: 10x+6y=76
Multiply 2x+3y=13 by 5: 10x+15y=65
[tex]\begin{bmatrix}10x+6y=76\\ 10x+15y=65\end{bmatrix}[/tex]
so
[tex]10x+15y=65[/tex]
[tex]-[/tex]
[tex]\underline{10x+6y=76}[/tex]
[tex]9y=-11[/tex]
now solving 9y = -11 for y
[tex]9y=-11[/tex]
divide both sides by 9
[tex]\frac{9y}{9}=\frac{-11}{9}[/tex]
Simplify
[tex]y=-\frac{11}{9}[/tex]
For 10x+6y=76 plug in y = -11/9
[tex]10x+6\left(-\frac{11}{9}\right)=76[/tex]
subtract 6(-11/9) from both sides
[tex]10x+6\left(-\frac{11}{9}\right)-6\left(-\frac{11}{9}\right)=76-6\left(-\frac{11}{9}\right)[/tex]
[tex]10x=\frac{250}{3}[/tex]
Divide both sides by 10
[tex]\frac{10x}{10}=\frac{\frac{250}{3}}{10}[/tex]
[tex]x=\frac{25}{3}[/tex]
Therefore, the solution to the system of equations is:
[tex]x=\frac{25}{3},\:y=-\frac{11}{9}[/tex]

✓Change in price= ($60 - $33)
=$27
✓percent change in price= change in price/ original price ×100%
✓percent change in price= ($27/$60) × 100%
= 0.45×100%
=45%
Hence, the percent change is 45%

so x+10+x+10+3x=180(all angles added in a triangle gives 180)
5x+20=180
5x=180-20
5x=160
x=160/5

Answer:
The completed table is shown below
Step-by-step explanation:
Proportional Relationship
Two variables H and M have a proportional relationship if the following equation is satisfied:
M = kH
Where k is the constant of proportionality.
The table shows one complete point: H=1.5, M=6. This allows us to find the value of k:
6 = 1.5k
k = 6/1.5 = 4
Now we know the complete relationship between distance and time:
M = 4H
To complete the table, we just give the required values and calculate the corresponding value.
For H=0 hours, M=4*0 = 0 miles
For H=0.5 hours, M=4*0.5 = 2 miles
For H=1 hours, M=4*1 = 4 miles
For H=6.5, M=4*6.5 = 26 miles
For M=12 miles, H=12/4 = 3 hours
The completed table is shown below
The answer is not A or B
Answer:
C) 4
Step-by-step explanation:
Arcs on one side of the diameter adds upto 180°.
Therefore,
[tex](2 + 17x) \degree + 54 \degree + 56 \degree = 180 \degree \\ \\ (2 + 17x) \degree + 110 \degree = 180 \degree \\ \\ (2+ 17x) \degree = 180 \degree - 110 \degree\\ \\ (2 + 17x) \degree = 70 \degree \\ \\ 2 + 17x = 70 \\ 17x = 70 - 2 \\ \\ x = \frac{68}{17} \\ \\ x = 4[/tex]
Answer:
Choice C) 4
Step-by-step explanation:
You can do this in multiple different ways but I will do it in the way I believe will be the fastest.
So since we already know everything on one side of the line, we can use that to find x. The line is 180° and since the angles are on the line we know that they will all add up to 180.
For this we will need an equation:
[tex]2+17x+54+56=180[/tex]
Now we add the like terms:
[tex]112+17x=180[/tex]
Subtract the 112 on both sides:
[tex]17x=68[/tex]
Divide the 17 on both sides:
[tex]x=4[/tex]
Shayla sells renters' insurance. Her company recently changed how it pays employees.
Under the old system, she received a 15% commission on each insurance policy that she
sold. Now there is a new system where she receives $750 for each insurance policy she
sells. If she sells a $5,000 insurance policy, how much more or less of a commission does
she make under the new system?
A.$50 less
B.$112.50 more
C.$112.50 less
D.The commissions are the same.
Answer:
100 + 15 = 115
5000/100 X 115 = 5750
