Anyone know the answer to this algebra problem?

ikadub [295]

Answer: $\bold{a=1\qquad b=\dfrac{1}{16}\qquad c=\dfrac{1}{64}\qquad d=1\qquad e=\dfrac{4}{9}\qquad f=\dfrac{16}{81}}$

<u>Step-by-step explanation:</u>

$\begin{array}{c|l}\underline{\quad x\quad}&\underline{\quad 4^{-x}\qquad \qquad}\\-1&4^{-(-1)}=4^1=4\\\\0&4^{-(0)}=4^0=1\\\\2&4^{-(2)}=\dfrac{1}{4^2}=\dfrac{1}{16}\\\\4&4^{-(4)}=\dfrac{1}{4^4}=\dfrac{1}{64}\end{array}$

$\begin{array}{c|l}\underline{\quad \bigg x \quad}&\underline{\quad \bigg(\dfrac{2}{3}\bigg)^x\qquad \qquad}\\\\-1&\bigg(\dfrac{2}{3}\bigg)^{-1}=\dfrac{3}{2}\\\\0&\bigg(\dfrac{2}{3}\bigg)^{0}=1\\\\2&\bigg(\dfrac{2}{3}\bigg)^{2}=\dfrac{2^2}{3^2}=\dfrac{4}{9}\\\\4&\bigg(\dfrac{2}{3}\bigg)^{4}=\dfrac{2^4}{3^4}=\dfrac{16}{81}\end{array}$

Find the slope of the line. 5x – 2y = 7

nika2105 [10]

Answer:

Final answer is slope $m=\frac{5}{2}$

Step-by-step explanation:

Given equation is $5x-2y=7$

Now question says to find the slope.

Since given equation $5x-2y=7$ is a linear equation so we need to compare $5x-2y=7$ with slope intercept formula $y=mx+b$ to get the value of slope m.

Since $5x-2y=7$ is not in that form so first let's rewrite it in y=mx+b form

$5x-2y=7$

$-2y=-5x+7$

$y=\frac{-5x+7}{-2}$

$y=\frac{5}{2}x-\frac{7}{2}$

Now comparing with y=mx+b, we get $m=\frac{5}{2}$

Hence final answer is slope $m=\frac{5}{2}$
