Answer:
The answer is
[tex] \huge y = - \frac{1}{4} x - 6[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is ( 8 , - 8) and slope -1/4
We have
[tex]y + 8 = - \frac{1}{4} (x - 8) \\ y + 8 = - \frac{1}{4} x + 2 \\ y = - \frac{1}{4} x + 2 - 8[/tex]
We have the final answer as
[tex]y = - \frac{1}{4} x - 6 \\ [/tex]

Charlie wants to order lunch for his friends. He'll order sandwiches and a $2 kid's meal for his little brother. Charlie has $32. How much can he spend on each sandwich if they are all the same price? "choose two answers" A) Inequality: 2x+6<32. B)Answer $5 or less. C) Inequality 6x+2 ≤32.D)Answer $13or less. E) Inequality 2x+6≤32. F) Inequality 6x+2≥32
So, obviously, since one of the prices is given, which is $2.00 for the kid's meal, then you need to subtract that from his $32.00 total to know what number you need to divide into the 6 sandwiches. So, so far you have $30.00. If you divide $30.00 by the 6 sandwiches, you will find out he could only spend $5.00 per sandwich. So basically, you got the expression of (32 -2) / 6 in order to find out that your answer is $5.00. Looking at you answer choices, I can see right away that D is correct. For the inequality, I can see that B would be the correct answer for this problem because he can't go over budget. So, your answers are B and D.
Hope this helps have a nice day and a brainlylist would be appreciated
A cheese pizza at Chicago's Deep Dish pizza costs $7. Each topping costs an additional $0.75. A cheese pizza at Brooklyn's cost $12. Each topping costs an additional $0.50. Write an equation that represents how many toppings, y, must be added so that the two pizzas cost the same?
Step-by-step explanation:
Let the number of toppings be y
If cheese pizza at Chicago's Deep Dish pizza costs $7 and each topping costs an additional $0.75, the total amount of the dish pizza will be expressed as;
$7 + $0.75y ..... 1
Also, if a cheese pizza at Brooklyn's cost $12 and each topping costs an additional $0.50, then the total cost of cheese pizza will be;
$12 + $0.50y ........ 2
If the two pizzas cost the same, then equation 1 will be equal to equation 2 as shown;
7+0.75y = 12+0.50y
Make y the subject of the formula to generate the required equation for y:
0.75y-0.50y = 12-7
0.25y = 5
divide both sides by 0.25
0.25y/0.25 = 5/0.25
y = 5/0.25
y = 20
Hence the equation that represents how many toppings, y, must be added so that the two pizzas cost the same is y = 5/0.25 and the number of toppings added is 20.
2. Select the three (3) equations that are equivalent to the equation
X-0.10x+2.5 = 45.5
Show how you determined your answers.
A. 0.90x+2.5=45
B. 0.90x=43
C.0.90x=45.5
D. 1.10x+2.5=45.5
E. 2(x-0.10x+2.5)=91
Answer:
B. 0.90x=43
E.2(x-0.10x+2.5)=91
Step-by-step explanation:
Given equation:
x-0.10x+2.5 = 45.5
Let us simplify this;
Collect like terms;
x - 0.10x = 45.5 - 2.5
Simplify;
0.9x = 43 (Option A)
Also;
x-0.10x+2.5 = 45.5
Simplify by multiplying both sides by 2;
2(x - 0.10x + 2.5) = 2(45.5)
2(x - 0.10x + 2.5) = 91.0
Also;
x-0.10x+2.5 = 45.5
0.9x + 2.5 = 45.5
Those are the three scenarios
Find 4ab when (a+b)=15 and (a-b)=12
Answer:
81
Step-by-step explanation:
here,
(a+b)=15 -------(1)
(a-b)=12 -------(2)
Equating the equation (1) and (2)
a + b = 15
a - b = 12
(b gets cancelled having opposite signs)
or, 2a = 27
or, a = 27÷2
a = 13.5
then, putting value of a in equation (1)
a+b=15
or, 13.5 + b=15
or, b=15-13.5
b=1.5
lastly,
4ab = 4×13.5×1.5
= 81

Aman, Anna and Tina are participating in the school race. Anna completes a lap in 120 minutes, Aman completes a lap in 240 minutes and Tina completes a lap in 60 minutes. If they all started at the same time, then after how long will they meet again?
Given:
Anna completes a lap in 120 minutes.
Aman completes a lap in 240 minutes
Tina completes a lap in 60 minutes.
To find:
The time after which they will meet again.
Solution:
They all started at the same time. So, the time after which they will meet again is the LCM of time taken by them to complete a lap.
Required time = LCM(120,240,60)
Factors of [tex]120 = 2\times 2\times 2\times 3\times 5[/tex]
Factors of [tex]240=2\times 2\times 2\times 2\times 3\times 5[/tex]
Factors of [tex]60=2\times 2\times 3\times 5[/tex]
So,
[tex]LCM(120,240,60)=2\times 2\times 2\times 2\times 3\times 5[/tex]
[tex]LCM(120,240,60)=240[/tex]
Therefore, after 240 minutes they will meet again.

Answer:
1.) 12 hours 2.) She made a multiplying error in the table.
Step-by-step explanation:
1.)
First, let's find the slope of this equation:
m = 135 - 81 / 5 - 3
m = 54/2
m = 27
Therefore, the equation should be y = 27x.
Now we substitute 324 for y and solve for x:
324 = 27x
12 = x (Divided 27 on both sides.)
Therefore, someone would have to work 12 hours in order to earn $324.
2.)
For this problem, it appears Amanda has found the correct equation for her recipe. When taking a look at the table, however, it seems as though she has made a multiplying error.

Answer:
a is 64 b 125 c 36
Step-by-step
so you do 2 times 2 times 2 = 8 because there is a 3 so you multiply it by it self how ever many times the number above it says so after you do that its the same for the other number so they are both 8 so 8 times 8 is 64

Explain how you would solve the equation -7 + x = 12 using the properties of equality. (Site 1)
Given problem:
Solve using the property of equality;
-7 + x = 12
The properties of equality are;
Addition. Definition. If x = y, then x + c = y + c. ...
Subtraction. Definition. If x = y, then x – c = y – c. ...
Multiplication. Definition. If x = y, then xc = yc. ...
Division. Definition. If x = y and c is not equal to 0, then x / c = y / c
Now;
- 7 + x = 12;
base on the properties of equality, to eliminate -7, add +7 to both sides;
-7 + 7 + x = 12 + 7
x = 19
Based on the properties of equality, the solution is 19
Solve for x. Justify each step. Given: 4x-9=99
Answer:
4x-9=99
1. Move -9 to the side with 99 and change the sign
4x=99+9
2. Sum
4x=108
3. Divide 4x by 4 to leave the X alone. Do the same on the other side.
4x/4=108/4
4. Complete the division
x=27
Verification:
4(27)-9=99
108-9=99
99=99 (TRUE)
Which procedure correctly simplifies the expression? ( 4 x − 3 ) − 2 ( x + 5 ) A. Step 1: 4 x − 2 x − 3 + 5 Step 2: 2 x + 2 B. Step 1: 4 x − 3 − 2 x − 5 Step 2: 2 x − 8 C. Step 1: 4 x − 3 − 2 x − 10 Step 2: 2 x − 13 D. Step 1: 4 x − 3 + 2 x + 10 Step 2: 6 x + 7
Answer:
Step 1: 4 x − 3 − 2 x − 10
Step 2: 2 x − 13
Step-by-step explanation:
Given the expression;
(4 x − 3) − 2 (x + 5)
The following steps/ procedure are to be taken when simplifying the expression.
open the parenthesis
(4 x − 3) − 2 (x + 5)
= 4x-3 -2(x)-2(5)
= 4x-3-2x-10
collect the like terms
= 4x-2x-3-10
simplify the resulting expression
= 2x-13
Hence the procedure that correctly simplifies the expression are:
Step 1: 4 x − 3 − 2 x − 10
Step 2: 2 x − 13

WILL MARK YOU BRAINLIEST HURRY PLZZZ!! I think its C but im not sure
Answer:
B
Step-by-step explanation:
You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.
The answer is B because if the triangle is a polygon then the conclusion would be that it is either acute or obtuse.
