4x - 20 = 5y
4x - 20 + 20 = 5y + 20
4x = 5y + 20
4x -5y = 5y - 5y + 20
4x - 5y = 20
Hope this helps!

Algebraic Proof Given: 3w + 4w - 2 = 12 Prove: w = 2

choli [55]

Answer:

Step-by-step explanation:

Replace W with 2

(3 x 2) + (4 x 2) -2 = 12

6 + 8 -2 = 12

add 6 + 8 = 14

14 - 2 = 12

Subract 14 - 2 = 12

which your answer in the end would be 12 = 12

which proves W is 2

4x2 + 4x - 1, evaluate and fully simplify each of the - For the function f(0) following f(s + h) f(x + h) - f(5) h 10

Andrew [12]

Given the function f(x);

$f(x)=-4x^2+4x-1$

Evaluating the function f(x+h);

$\begin{gathered} f(x+h)=-4(x+h)^2+4(x+h)-1 \\ f(x+h)=-4(x^2+2xh+h^2)^{}+4(x+h)-1 \\ f(x+h)=-4x^2-4h^2-8xh^{}+4x+4h-1 \end{gathered}$

So;

$f(x+h)=-4x^2-4h^2-8xh^{}+4x+4h-1$

Evaluating the second function;

$\begin{gathered} \frac{f(x+h)-f(x)}{h}=\frac{-4x^2-4h^2-8xh^{}+4x+4h-1-(-4x^2+4x-1)}{h} \\ \frac{f(x+h)-f(x)}{h}=\frac{-4x^2-4h^2-8xh^{}+4x+4h-1+4x^2-4x+1}{h} \\ \frac{f(x+h)-f(x)}{h}=\frac{-4x^2+4x^2-4h^2-8xh^{}+4x-4x+4h-1+1}{h} \\ \frac{f(x+h)-f(x)}{h}=\frac{-4h^2-8xh^{}+4h}{h} \end{gathered}$

simplifying further;
