Zinaida [17]

Answer:

Step-by-step explanation:

WA times AX = YA x YZ

8x5=40

because they have to equal each other we just have to divide 40 by 10

40/10=4 so segment YZ=4

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

brilliants [131]

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ -9}}\quad ,&{{ -3}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies -6
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-3)=-6[x-(-9)]
\\\\\\
y+3=-6(x+9)\implies y+3=-6x-54\implies y=-6x-57$

Use the zero product property to find the solutions to the equation x^2 + x -30=12

Alla [95]

Answer:

The solutions are x = -7, 6.

Step-by-step explanation:

To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.

$x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0$
