3(5 + -1e) + 2 = 10
(5 * 3 + -1e * 3) + 2 = 10
(15 + -3e) + 2 = 10
Reorder the terms:
15 + 2 + -3e = 10
Combine like terms: 15 + 2 = 17
17 + -3e = 10
Solving
17 + -3e = 10
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + -3e = 10 + -17
Combine like terms: 17 + -17 = 0
0 + -3e = 10 + -17
-3e = 10 + -17
Combine like terms: 10 + -17 = -7
-3e = -7
Divide each side by '-3'.
e = 2.333333333
Simplifying
e = 2.333333333</span>
W>10. 80-2w>50 subtract 80 on both sides and then divide by negative two.
Turn F(x) into vertex form:
y=x^2+8x+6
y-6=x^2+8x
y-6+16=x^2+8x+16
y+10=(x+4)^2
Thus the vertex is (-4,-10)
This is a minimum because the parabola is up up, or is positive
The first two
hope this helps
The answer is 39.470 because 39.472 is far from 39.450 and it’s 2 numbers passed 39.470.
