Answer: A

Step-by-step explanation:

$4x+4y=20$

We need to get this form: $y=mx+b$

we need to begin by isolating y on the left side. To do this, we must subtract 4x.

$4y=20-4x$

Rewrite it so that we get this form: $y=mx+b$

$4y=-4x+20$

Since y needs to be completely isolated, divide by 4.

$y=-\frac{4x}{4} +\frac{20}{5}$

Divide;

$y=-x+5$

Bridget, Jim and Krutika share some sweets in the ratio 4:5:1. Bridget gets 39 more sweets than Krutika. How many sweets does Ji

Yakvenalex [24]

Step-by-step explanation:

Let Bridget, Jim and Krutika's shares be 4x, 5x and x respectively.

According to the given information:

4x = x + 39

4x - x = 39

3x = 39

x = 39/3

x = 13

5x = 5*13 = 65

Hence, Jim got 65 sweets.

G(x)=15x-10 inverse function with steps please

Alexus [3.1K]

Answer:

The inverse function is g(x) =

$\frac{x + 10}{15}$

Step-by-step explanation:

You can find the inverse of any function by switching the g(x) value (or whatever the function value is labelled) and the x value. Then solve for the new g(x) value. The result will be your inverse function.

g(x) = 15x - 10 ---> Switch the g(x) and x

x = 15g(x) - 10 ---> Add 10 to both sides

x + 10 = 15g(x) ----> Divide both sides by 15.

$\frac{x + 10}{15} = g(x) ----> Switch the order$

= g(x) ----> Switch the order

g(x) =

$\frac{x + 10}{15}$

And that would be your inverse function.
