Answer:

1) f(5) = 7

2) f(0) = -2

3) p(-7) = -17

Step-by-step explanation:

1) f(a) = 2a - 3

f(5) = 2 · 5 - 3 = 10 - 3 = 7

2) f(x) = 2x - 2

f(0) = 2 · 0 - 2 = 0 - 2 = -2

3) p(n) = 2n - 3

p(-7) = 2 · (-7) - 3 = -14 - 3 = -17

John has 17000 - 2500 = 14500 left to pay after the down payment 

Then add on the finance charges 14500 + 4900 = 19400

The total of $19400 is to be paid over 60 monthly instalments, so John will be paying 19400÷60 = $323.30 per month

How do I solve this, it's not 10
guapka [62]

Answer:

26.7

Step-by-step explanation:

This is the answer because 26.7/20 = (16+26.7)/32

When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.

To solve, you create a formula.

(16+x)/32=x/20

Multiply both sides by 32 to get rid of the 32 in the left side.

16+x=32x/20

Multiply both sides by 20 to get rid of the 20 right side.

320+20x=32x

-20x on both sides to get all the variables on one side and all the nukbers on the other.

320=12x

Divide both sides by 12 to get x by itself

x=26.66667
