Answer:

a.f(-1)=2

b.f(3)=6

c. f(x-1)=x+2

Step-by-step explanation:

We are given that f(x)=x+1+2

a.We have to find the value of f(-1)

Substitute the value of x in the given function

Then, we get

f(-1)=-1+1+2=2

f(-1)=2

b.We have to find the value of f(3)

Substitute x=3 then we get

f(3)=3+1+2=6

f(3)=6

c.We have to find the value of f(x-1)

Replace x by x-1 then we get

f(x-1)=x-1+1+2=x+2

Hence, f(x-1)=x+2

I NEED HELP PICTURE PROVIDED!

Question 2:
The answer is 21
The two angles are vertically opposite, which makes them equal and also means we can make an equation:
4x - 4 = 3x + 17
- 3x
x - 4 = 14
+ 4
x = 21

Question 3:
The answer is 23
Again, the angles are vertically opposite, so we can make them equal each other:
5x - 53 = 3x - 7
- 3x
2x - 53 = -7
+ 53
2x = 46
÷ 2
x = 23

I hope this helps!

The Moores paid $6 more for skate rentals than the Cotters did. Together, the two families paid $30 for skate rentals.How many p
iren2701 [21]

Answer:

Step-by-step explanation:

Consider Cotters paid "x" dollars:

According to given condition:

Moores paid "x+6" dollars.

Both paid total $30

Hence,

(x) + (x+6) = 30

Solving for x:

2x +6 = 30

    2x = 30-6

    2x = 24

       x = 24/2

       x = 12

So amount paid by Moores  = x +6 = 12+6 = $18

*****To find number of pairs of skates: price of one pair must be given.

Please post complete question.

· y = 3x - 7<br> Find the slope
coldgirl [10]

Answer:

3

Step-by-step explanation:

the slope of an equation (y=mx+b) is always "m", or the coefficient right infront of x. in this case, y=3x-7, 3=m, -7=b. m is the slope, so the slope is 3.
