Answer:
–4
Step-by-step explanation:
observe
2x² + 8x = x² – 16
x² + 8x + 16 = 0
(x+4)² = 0
x + 4 = 0
x = –4
There are 26 boys and 19 girls,
Take away 7 from 45 to get 2g(# of girls)
45-7=38 38=2g To get to # of girls,find just one g
38/2=19 so 19 girls
45-19=boys 45-19=26 boys

Answer:
The y-intercept is (0, 5).
Step-by-step explanation:
We find the equation of the line in slope-intercept form:
y - y1 = m(x - x1)
y - 13 = 2(x - 4)
y = 2x - 8 + 13
y = 2x + 5 - This is slope-intercept form where the graph passes through the y-axis at y = 5.
