Math question<br><br><br>please help me
oee [108]
14000 ÷ 100 = 140
140 x 20 = 2800 = price of vat

14000 - 2800 = 11200 = total cost of van

11200 ÷ 100 = 112
112 x 4 = 448 = deposit

11200 - 448 = 10752
10752 ÷ 24 = 448

Which equation is the inverse of y = 7x2 – 10?
MrRissso [65]

we have

y=7x^{2}-10

To find the inverse

Step 1

Exchanges the variables, x for y and y for x

x=7y^{2}-10

Step 2

Isolate the variable y

x=7y^{2}-10

7y^{2}=x+10

y^{2}= \frac{x+10}{7}

Square Root both sides

y=(+/-)\sqrt{\frac{x+10}{7}}

Step 3

Let

f(x)^{-1}=y

so

f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}

therefore

<u>the answer is</u>

The inverse is  

f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}
