Margaret [11]
Y-4=4/3 (x-3)
standard form would be where you is singled out giving the y intercept form
solve for y
y-4=4/3 (x)-4/3 (3)
y-4=4/3 (x)-4
y=4/3 (x)-4+4
y=4/3 (x)

. How do you turn a fraction into a decimal.
Aleonysh [2.5K]
You have to divide the numerator (the top number) by the denominator (the bottom number). For example: 1/2 is a fraction, its equivalent (equal) decimal is .5. How did we get that? Divide the 1 by the 2 :) I hope this helps :)

the answer to this equation is negative 6 but I don’t know to explain how I got the answer is word form.
SpyIntel [72]

The value of k is –6.

Solution:

Given equation:

$\frac{5 \cdot 5^{k}}{5^{-8}}=5^{3}

<u>To find the value of k:</u>

$\frac{5 \cdot 5^{k}}{5^{-8}}=5^{3}

Using exponent rule: a^m \cdot a^n = a^{m+n}

$\frac{5^{1+k}}{5^{-8}}=5^{3}

Using exponent rule: \frac{1}{a^{-m}}  = a^{m}

$ 5^{1+k} \cdot 5^{8}=5^{3}

Using exponent rule: a^m \cdot a^n = a^{m+n}

$ 5^{1+k+8}=5^{3}

$ 5^{k+9}=5^{3}

<em>If the bases are same then, we can equate the powers of the bases.</em>

i. e. If a^m = a^n then m = n.

k + 9 = 3

Subtract 9 from both sides of the equation, we get

k = –6

Hence the value of k is –6.
