4x^2 - 30 = 34
4x^2 = 34 + 30
4x^2 = 64
x^2 = 64/4
x^2 = 16
x = sqrt 16
x = -4 and 4......E and F

Irst Step:
<span>54.08 * 0.08 </span>
<span>(total) * (sales tax, percent in decimal) </span>
<span>== $4.33 (4.3264) (tax) </span>
<span>Second Step: </span>
<span>54.08 + 4.33 </span>
<span>(total) + (tax) </span>
<span>== $ 58.41 </span>
<span>(Total with tax)</span>
Answer:
y = 7/5x + 18/5
Step-by-step explanation:
so we have y = mx + b
f(1) = 5
f(-4) = -2
so let's find b
so like if you do (5 - (-2))/(1 - (-4)) you get (5 + 2)/(1 + 4) = 7/5
y = 7/5x + b
so now we can plug in a value like f(1) = 5
5 = (7/5)1 + b
b = 18/5
