D.
-1,500
Answer:
i know its c
Step-by-step explanation:
i had this question yesterday
Answer:
the slope is -400
Step-by-step explanation:
In order to find the slope, we must use the slope equation
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
where it was considerated 2 points of the line, i.e.,
(x_1,y_1) and (x_2,y_2)
In this case, we observe that there are 2 "easy" points,
(x_1,y_1)=(0,4000) and
(x_2, y_2)=(10,0)
By substituying these point in the slope equation, one has
m=[tex]\frac{0-4000}{10-0}[/tex]
m=[tex]\frac{-4000}{-10}[/tex]
Hence, m=-400.

Solve the equation.
y + 6 = -3y + 26
Oy= -8
O y = -5
O y = 5
Oy = 8
The solution to the equation is y = 5.
Therefore, the correct answer is "O y = 5."
Option C.
Here,
Let's solve the equation step by step to find the value of y:
Combine the y terms on the left side of the equation:
y + 3y + 6 = 26
Combine the y terms on the left side of the equation:
4y + 6 = 26
Move the constant term to the other side of the equation:
4y = 26 - 6
Simplify the right side:
4y = 20
Now, solve for y by dividing both sides of the equation by 4:
y = 20 / 4
y = 5
So, the solution to the equation is y = 5.
Therefore, the correct answer is "O y = 5."
Option C.

The product of 4 and the sum of a number x and 8
Answer:
8(x+3)
Explanation:
"The product of 8 and" means 8 is going to be multiplied times another quantity. "...the sum of a number x and 3" means that 8 is going to be multiplied times (x+3).
This is represented by 8×(x+3), which simplifies to 8(x+3).

The perimeter of a football field is 920 feet. The width is 60 feet more than one-third of the length. What are the dimensions of a football field?
Given:
Perimeter of a football field = 920 feet.
The width is 60 feet more than one-third of the length.
To find:
The dimensions of a football field.
Solution:
Let the length of the field be x.
Then, width = [tex]\dfrac{1}{3}x+60[/tex]
We know that,
[tex]Perimeter = 2( length + width)[/tex]
[tex]920 = 2(x+\dfrac{1}{3}x+60)[/tex]
[tex]920 = 2(\dfrac{4}{3}x+60)[/tex]
[tex]920 =\dfrac{8}{3}x+120[/tex]
Subtract both sides by 120.
[tex]920-120 =\dfrac{8}{3}x+120-120[/tex]
[tex]800 =\dfrac{8}{3}x[/tex]
Multiply both sides by 3.
[tex]2400 =8x[/tex]
Divide both sides by 8.
[tex]300 =x[/tex]
Now,
[tex]Length = 300\text{ feet}[/tex]
[tex]Width=\dfrac{1}{3}(300)+60[/tex]
[tex]Width=100+60[/tex]
[tex]Width=160\text{ feet}[/tex]
Therefore, the length and width of the football field are 300 feet and 160 feet respectively.

3). Find x
4). find m
5). Find m < y
6.) Find m
Answer:
x = 30
m<Y = 60
m<Z = 60
m<X = 60
Step-by-step explanation:
All of this should add up to 180 so...
2x + 2x + 3x - 30 = 180 (collect like terms)
7x - 30 = 180 (add 30 on both sides)
7x = 210 (divide by 7 on both sides)
x = 30
PLUG IN
2(30) = 60
3(30) - 30
90 - 30 = 60
m<Y = 60
m<Z = 60
m<X = 60

The recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people? Use the rate table to solve the proportion.
StartFraction 6 over 9.75 EndFraction = StartFraction 24 over c EndFraction
It would cost $ to serve 24 people.
Answer:
$39
Step-by-step explanation:
Given parameters:
Cost of ingredient = $9.75
Number of people = 6 people
Unknown:
How much will it cost to serve 24 people = ?
Solution:
To solve this problem, let us find the rate of each recipe per person;
Rate = [tex]\frac{Number of people }{Cost of ingredient}[/tex]
Insert parameters and solve;
Rate = [tex]\frac{6}{9.75}[/tex] = 0.62people/$
For 24 people, it will cost;
Cost of ingredient = [tex]\frac{Number of people }{rate}[/tex]
Cost of ingredient = [tex]\frac{24}{0.62}[/tex] = $39

A. -10 b.-6
Answer:
(-10,-6)
Step-by-step explanation:
(8 + b) / 2 = - 1
(8 + b) = - 1 * 2

Use the inequalities to describe the shaded area on the grid
Answer:
x≥-2
y<3
y≥x+3
Step-by-step explanation:
For x≥-2 the line is passing through -2 on the X axis
For y<3 the dotted line is passing through 3 on the y axis and as it is dotted it is just less than
For y≥x+3 the line is passing through -3 on the x axis and 3 on the y axis so it must be y=x+3. Then you apply the inequality so it becomes y≥x+3
Hope it helps :)
The inequalities to describe the shaded area on the grid are
[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]
The shaded area of the grid is surrounded by three lines the equations of all three lines are given as below in form of inequalities.
For a solid line the " equality" is included but for a dashed line " equality" is not included.
x ≥ -2
y < 3
The equation of third line can be found out by writing standard form of straight line
[tex]\rm y = mx +c \\m = Slope \;of\; the\; line\\c = y\; axis \; intercept \; value[/tex]
As we can observe from the figure that the line passes through (0,3) and (-3,0) and hence we write the equation of line as
[tex]\rm y = (3-0) /(0-(-3)) ( x+3) \\y = 1\times x + 3\\y = x+3 \\So \; the\; inequality\; can \; be\; written\; as\\y\geq x+3[/tex]
Since the area above the line y = x+3 is of our concern hence greater than equal to sign is used.
So the inequality for third line is
[tex]\rm\bold{ {y\geq x+3}}[/tex]
The inequalities to describe the shaded area on the grid
[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

You have been contracted to replace a countertop in a kitchen. You will get paid $1,000 to do the job. You can complete the job in three days working 8 hours a day. You will need to pay the cost of the materials, which is $525, with the $1,000 that you receive to do the job. How much will you be paid per hour for your time?
Answer:
$19.79 cents (rounded to the nearest cent)
Step-by-step explanation:
first subtract the amount needed for materials from your total pay
(1000 - 525 = 475)
take 475 and divide that among the hours you work.
475 / 24 = 19.7916666
