Find the slope and the y-intercept of the graph of the linear equation. 1. y=3x-7 2. y-1=-2/3x
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1

The graph of a proportional relationship contains the point (8,4). What is the corresponding equation? Enter your answer as a fraction in simplest form by filling in the boxes.
y= — x
Given:
The graph of a proportional relationship contains the point (8,4).
To find:
The corresponding equation.
Solution:
If y in directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
The graph of a proportional relationship contains the point (8,4).
Putting x=8 and y=4 in (i), we get
[tex]4=k(8)[/tex]
[tex]\dfrac{4}{8}=k[/tex]
[tex]\dfrac{1}{2}=k[/tex]
Putting [tex]k=\dfrac{1}{2}[/tex] in (i), we get
[tex]y=\dfrac{1}{2}x[/tex]
Therefore, the required equation is [tex]y=\dfrac{1}{2}x[/tex].

The measure of angle Q is 70 degrees. Find the measure of angle P.
Answer:
∠ P = 40°
Step-by-step explanation:
Since PQ = PR then the triangle is isosceles and the base angles are congruent, then
∠ R = ∠ Q = 70° , so
∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°
∠ P = 180° - 140° = 40°

The length, l , of a rectangle is 3 cm longer than twice the width, w. The perimeter of the rectangle is 66 cm.
Which system of linear equations could be used to find the length and width of the rectangle?
A. l = 3w + 2
2l + 2w = 66
B.l = 3w + 2
l + w = 66
C.I= 2w + 3
l + w = 66
D. l = 2w + 3
2l + 2w = 66
Answer:
The system of linear equations that could be used to find the length and width of the rectangle will be:
l = 2w + 3 cm
2w + 2l = 66
Hence, option D is correct.
Step-by-step explanation:
Let the width of the rectangle be = w cm
Given that the length, l, of a rectangle is 3 cm longer than twice the width, w.
Thus, the length of the rectangle be:
l = 2w + 3 cm
We know that the perimeter of the rectangle is:
P = 2w + 2l
Given that the perimeter of the rectangle = P = 66 cm
so substitute P = 66 in P = 2w + 2l
P = 2w + 2l
66 = 2w + 2l
Therefore, the system of linear equations that could be used to find the length and width of the rectangle will be:
l = 2w + 3 cm
2w + 2l = 66
Hence, option D is correct.

If a company employed 50 people in 1995, and tripled their employment by 2005, how many total people would be employed if there are 40% more employees than in 2005 by 2015?
Answer:
210 people
Step-by-step explanation:
so we know that the number of employees in 2005 is (50)3= 150
so taking 14/10* 150= we get 14*15= 210 people
How do you solve fractions and multiplication in algebraic, ex:1/3× -4
Answer: x=12
Step-by-step explanation:
1/3 x -4
1/3x=4 <---- First add 4 to each side of the equation (moves the "-4")
1/3x(3)=4(3) <---- Muliply each side by "3" to get rid of the fraction
x=12
A jelly bean factory packaged 913 special ordered bags last Tuesday. The shift manager randomly picked seven bags to count the number of jelly beans.
8, 6, 11, 15, 6, 11, 6
If the sample was representative of all the bags packaged on Tuesday, what was the mode of the number of jelly beans of all the bags?
A. 6
B. 15
C. 8
D. 11
Answer:
I think the answer is 1/5
Step-by-step explanation:
Add up the total number of jellybeans, 20 + 45 + 30 + 5 = 100.
Divide the number of watermelon jellybeans by the total: 20/100 and reduce the fraction to 1/5.
Hope this help you! :)

Answer:
No, A is
Step-by-step explanation:
You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.
============================================================
Explanation:
Let's check if choice C is the answer or not
We will plug in x = -2 and y = 1 into the inequality to get
y - 3x < 1
1 - 3(-2) < 1
1 + 6 < 1
7 < 1
That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.
---------------
It turns out that choice A is the answer because
y - 3x < 1
0 - 3(0) < 1
0 - 0 < 1
0 < 1
Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.
I'll let you check the other answer choices. You should find them to be false

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Answer:
x = -4, 4
Step-by-step explanation:
Given graph in the attachment represents the function y = f(x)
Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.
Since, graph of the function touches and crosses at x = -4 and x = 4
Therefore, all real solutions of the function are x = -4 and x = 4
