1) 15^2=4^2+2(32)x 2) 105=45+5x

1 answer:

8 0

① 15² = 4² + 2(32) x
225 = 16 + 64x
-64x = 16 - 225
-64x = -209
x = 209/64

② 105 = 45 + 5x
-5x = 45 - 105
-5x = -60
x = 60/5
x = 12

A line with a slope of -1 passes through the point (2,-1). If (-4, p) is another point on the line,

Thepotemich [5.8K]

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{p}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{p}-\stackrel{y1}{(-1)}}}{\underset{run} {\underset{x_2}{-4}-\underset{x_1}{2}}}~~= ~~\stackrel{\stackrel{m}{\downarrow }}{-1}\implies \cfrac{p+1}{-6}=-1\implies p+1=6\implies p=5$
