Please help! will mark brainliest For a given input value b, the function f outputs a value a to satisfy the following equation.
4a + 7b = -52
Write a formula for f(b) in terms of b

a = f (b) = - 13 ⁷/4 b

Step-by-step explanation:

Since we have given that

4a + 7b = 52

We need to write a formula for f (b) in terms of b So , it becomes :

4a = 52 - ⁷b

a = -52- ⁷b ÷ 4

a = -52÷4 - ⁷b ÷ 4 -

a = 13 = ⁷b ÷ 4

Hence our required formula becomes :

a = f (b) = - 13 =⁷b ÷ 4

The ⁷b ÷ 4 means ⁷b over 4 :)

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
