Answer:
x = -2 ±sqrt( 19)
Step-by-step explanation:
x^2 + 4x = 15
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 = 4
Add it to each side
x^2 + 4x+4 = 15+4
(x+2)^2 = 19
Take the square root of each side
sqrt( (x+2)^2) =±sqrt( 19)
x+2 = ±sqrt( 19)
Subtract 2 from each side
x+2-2 = -2 ±sqrt( 19)
x = -2 ±sqrt( 19)
Y = 5(x+4)-6
x = 5(y+4)-6
x = 5y +20 - 6
x= 5y +14
5y = x-14
y = (x-14)/5
<span>
when x = 19, y = (19-14)/5 </span>
y = 5/5
<span>y=1
In short, Your Answer would be Option 2

Answer: Lena saved up $3,475 in 25 weeks
Step-by-step explanation:
150 + 532 = 682
682/4 = 133
133 x 21 = 2,793
2,793 + 682 = 3,475
Hope this helps :)
Y = x - 2
Ex.
y = 1 - 2
y = -1
