Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2
Answer
1.) B
2.) 3 hours
Step-by-step explanation:
1.) option B is correct I think because it shows he will either be equal to or less than how much money he wants to spend
2.) i got three because if you sent up the equal I picked in question one then you subtract 28 from 250 giving u 222 and you divide that by 65 giving you 3.4 but he only charges by the whole hour so that .4 of an hour he wouldn't charge you for

answer is 7.7"
Answer:
g = 23/16
Step-by-step explanation:
3/16 = (-5/4) + g
Add 5/4 on both sides.
3/16 + 5/4 = g
Make denominators equal and add.
3/16 + 20/16 = g
23/16 = g
Answer:
Slope of the tangent line at x=-1

Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given function
y = f(x) = e ˣ⁻⁴ ...(i)
Differentiating equation (i) with respective to 'x' , we get
