Answer:

f ( -2 ) = 30

g ( -2 ) = 3

Step-by-step explanation:

when it says f(x) and then has f(-2) - you fill in all x's in the equation with -2.. like this:

f(x) = -7(-2-2) +2                         g(x) = 2(-2)^2 -5

f(x) = -7(-4) +2                             g(x) = 2(4) -5

f(x) = 28 + 2                                g(x) = 8 - 5

f(x) = 30                                      g(x) = 3

hope this helps!!

Barbara orders her groceries from a store that charges $15 plus the cost of her groceries to deliver her groceries to her home.
crimeas [40]

Answer:

The correct answer is Total Cost Payable = $Exp + $15, where $Exp is the total price of the groceries bought by Barbara

Step-by-step explanation:

Barbara orders her groceries. Let us consider that she orders groceries worth $Exp from a store.

Extra charges levied by the store for delivering the groceries to Barbara's house is $15.

Thus the total payable charge by Barbara for her groceries should include the total price of the groceries and the delivery charges levied by the store.

Thus the Total Cost Payable by Barbara is the sum of the total expenditure by her on the groceries and the delivery charge.

∴ The total cost payable = $Exp + $15.

X + 3 = 8x - 11 Question options: 2 1 -1 4
hichkok12 [17]

Hello there! Your answer is 2.

When we are given this problem: x + 3 = 8x - 11 we are solving for the value of X. We want to isolate all like terms on one side of the equation. To do this, let's add 11 to the left side so the - 11 cancels out on the right.

x + 3 + 11 = 8x - 11 + 11 - After this, add like terms. (so 3 + 11 and - 11 + 11)

x + 14 = 8x - Now, negative 11 plus positive 11 have canceled each other out, we have to subtract x from the left side.

x - x + 14 = 8x - x

14 = 7x - Our last step is do divide both sides of the equation by 7 to finish isolating x.

14/7 = 7/7x

2 = x.

This is your final answer!

Find the value of x.<br> (x + 30)
taurus [48]

Answer:

x=55

Step-by-step explanation:

The exterior angles of a polygon add to 360.

x+x+x+x+x+x+30 = 360

Combine like terms

6x+30 = 360

Subtract 30 from each side

6x+30-30 = 360-30

6x = 330

Divide by 6

6x/6 =330/6

x =55
