Answer:
Step-by-step explanation:
The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1.
In this case, since the subtraction sign is before the variable, you will need to make the variable positive by making the coefficient of variable y, -1.
In short terms, your answer is -1. :)

Select all the expressions that are equivalent to 24x + 12.
2(12x + 6)
–6(–4x – 2)
–3(8x – 4)
12(1 + 2x)
–4(–6 – 3x)
Answer:
2(12x + 6)
-6(-4x - 2)
12(1 + 2x)
The expressions that are equivalent to 24x + 12 are:
2(12x + 6)
-6(-4x - 2)
12(1 + 2x)
Let's go through each expression and simplify them to determine if they are equivalent to 24x + 12.
2(12x + 6):
We can use the distributive property to simplify this expression:
2 * 12x + 2 * 6 = 24x + 12
This expression is equivalent to 24x + 12.
–6(–4x – 2):
Again, using the distributive property, we simplify:
–6 * –4x + –6 * –2 = 24x + 12
This expression is equivalent to 24x + 12.
–3(8x – 4):
Once again, applying the distributive property:
–3 * 8x + –3 * –4 = –24x + 12
This expression is not equivalent to 24x + 12.
12(1 + 2x):
Using the distributive property:
12 * 1 + 12 * 2x = 12 + 24x = 24x + 12
This expression is equivalent to 24x + 12.
–4(–6 – 3x):
Applying the distributive property:
–4 * –6 + –4 * –3x = 24 + 12x = 12x + 24
This expression is not equivalent to 24x + 12.

Camillo is making gourmet peanut butter and jelly sandwiches for a food challenge.
PLS HELP ASAP!!What is the unit price of a loaf of bread at each store?
Store A:
Store B:
Store C:
Store D:
Solution:
The unit price of an item is the price for a single unit of measure of that item. It is measured in price / unit measure.
unit price of a loaf of bread at each store = cost of the loaf of bread / number of loaves
For store A, unit price = $5.94 / 3 loaves = $1.98 per loaf
For store B, unit price = $7.80 / 4 loaves = $1.95 per loaf
For store C, unit price = $10.50 / 5 loaves = $2.10 per loaf
For store D, unit price = $12.12 / 6 loaves = $2.02 per loaf
Answer:
yup the person above me is right but for C its $2.01 :>

True or False: The points (6,13) (21, 33) and (99, 137) all lie on the same line. The equation of the line is y = 4/3x + 5. PLS HELP ASAP
Answer:
This is true look at picture for clarification
Answer:
True
Step-by-step explanation:
To see if the points all lie on the line y = 4/3x + 5, substitute their x and y values into the equation, solve, and see if the equation is true.
1) First, substitute the x and y values of (6,13) for the x and y in the equation and solve:
[tex]13 = \frac{4}{3} (6) + 5 \\13 = \frac{24}{3} +\frac{15}{3} \\13 = \frac{39}{3}\\13 = 13[/tex]
The result is a true equation. Thus, (6,13) is on the line.
2) Do the same with the point (21,33):
[tex]33 = \frac{4}{3} (21) + 5 \\33 = \frac{84}{3} +\frac{15}{3} \\33 = \frac{99}{3} \\33 = 33[/tex]
The result is a true equation. Thus, (21,33) is on the line.
3) Finally, do the same with (99, 137):
[tex]137 = \frac{4}{3} (99) + 5\\137 = \frac{396}{3}+\frac{15}{3} \\137 = \frac{411}{3} \\137 = 137[/tex]
The result is a true equation. Thus, (99, 137).
All three points are on the line, thus the statement is true.
Annie has 4 1/2 feet of rope what is the greatest number of 3/4 foot pieces that annie can cut from the rope
Answer:
6
Step-by-step explanation:
4 1/2 divided by 3/4 is 6. so 6 pieces
The greatest number of 3/4 foot pieces that Annie can cut from the rope
is 6.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Annie has 4 1/2 feet of rope.
Therefore, The greatest number of 3/4 foot pieces Annie can cut can be obtained by dividing the length of the total rope by the length of each piece which is,
= (4 1/2)/(3/4).
= (9/2)×(4/3).
= 36/6.
= 6.
So, 6 pieces are possible.

if y(x) = 5x-2 and g(x) = 2x + 1, find (f + g)(x).
Answer:
(f + g)(x) = 7x - 1
Step-by-step explanation:
Given : f(x) = 5x – 2 and g(x) = 2x + 1
We have to find (f + g)(x)
Consider (f + g)(x) = f(x) + g(x)
Also, given f(x) = 5x – 2 and g(x) = 2x + 1
Substitute, we have,
f(x) + g(x) = 5x - 2 + 2x + 1
LIKE TERMS are terms having same variable with same degree.
Simplify by adding like terms, we have,
f(x) + g(x) = 5x + 2x - 2 + 1
f(x) + g(x) = 7x - 1
Thus, (f + g)(x) = 7x - 1
