What integer represents w? 9 : 4 = 27 : w

joja [24]

Answer:

Step-by-step explanation:

This is because to get 9 to 27 you have to multiply 9 by 3, therefore you have to multiply 4 by 3 due to the fact what you do to one side you have to do to the other to make it all equal:

9 x 3 = 27

4 x 3 = 12

ratio- 9 : 4 = 27 : 12

NO LINKS!! Use the method of substitution to solve the system. (If there's no solution, enter no solution). Part 11z

Roman55 [17]

Answer:

$(x,y)=\left(\; \boxed{-1,-8} \; \right)\quad \textsf{(smaller $x$-value)}$

$(x,y)=\left(\; \boxed{5,16} \; \right)\quad \textsf{(larger $x$-value)}$

Step-by-step explanation:

Given system of equations:

$\begin{cases}y=x^2-9\\y=4x-4\end{cases}$

To solve by the method of substitution, substitute the first equation into the second equation and rearrange so that the equation equals zero:

$\begin{aligned}x^2-9&=4x-4\\x^2-4x-9&=-4\\x^2-4x-5&=0\end{aligned}$
