Distributive property states a(b+c) = ab + ac

9(10 + x) = 90 + 9x

Your answer is B. 90 + 9x.

I Have 10 Minutes Hurry for Brainlist and pls be accurate

yulyashka [42]

To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.

$\large\red{\sf{y=3x-1}}$

$\begin{gathered}\\ \sf\longmapsto 9=3(1)-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=3-1\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠2 \end{gathered}$

$\large\green{\sf{y=5x+4}}$

$\begin{gathered}\\ \sf\longmapsto 9=5(1)+4\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=5+4\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=9\end{gathered}$

$\large\blue{\sf{y=-2x-8}}$

$\begin{gathered}\\ \sf\longmapsto 9=-2(1)-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=-2-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠10\end{gathered}$

$\large\pink{\sf{y=6x-8}}$

$\begin{gathered}\\ \sf\longmapsto 9=6(1)-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9=6-8\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9≠-2\end{gathered}$

Hence, Option B. y=5x+4 satisfies the system (1,9)

SOMEONE PLS HELP I WANT TO GO TO BED AND EXPLAIN HOW TO PLS

vlabodo [156]

Answer:

40 degrees

Step-by-step explanation:

2x-30+x=90

Then you add x to 2x which will be 3x so now its

3x-30=90

add 30 to both sides

3x=120

divide 3 from both sides

x=40

Since Angle QPR is virticle to 2x-30+x=90

Angle QPR is 40 degrees
