Solve the equation 3(x+4.5x ) = 36. Explain your reasoning THOROUGHLY.

Vesna [10]

Answer:

$x \approx 2.18$

Step-by-step explanation:

$3(x+4.5x)=36$

we can use the distributive property and get

$3(x)+3(4.5x)=36\\\\3x+13.5x=36\\\\$

and we can add like terms

$(3+13.5)x=36\\\\16.5x=36$

and know we divide both sides by 16.5

$16.5x*(\frac{1}{16.5})=36*(\frac{1}{16.5})\\\\x=\frac{36}{16.5}$

and doing the dvision we get that

$x\approx 2.18$

The points (9, 2) is reflected across the x axis what are the cordinates of the reflection

user100 [1]

When reflecting about the x axis, the x value remains the same and the y value becomes the inverse of the original y value (opposite)

The point (9,2) would become (9,-2)

If y varies directly with x, find the constant of variation with x = 4 and y = -24

olganol [36]

Use the formula y=kx for this equation.
so considering that Y equals -24 then X and K must also equal that number
we already know that X is -4 but we dont know what K is.
so we divide -24 by -4 and get an answer of a positive 6 but the answer is not proven yet.
-4 times 6 is -24 meaning that the answer is 6
