Is this answer correct?

Answer:

Step-by-step explanation:

How to solve :

(a-4)/(a^2+8a+12)*(a^2-2a-48)/(a^2+4a-32)

Factor:

a^2+8a+12 = (a+6)(a+2)

a^2-2a-48 = (a-8)(a+6)

a^2+4a-32 = (a+8)(a-4)

simplify a+6, and a-4

you are left with (a-8)/(a+2)(a+8) = (a-8)/(a^2+10x+16)

PLEASE AWNSER QUICKLY !!!!

allsm [11]

The scientific notation should mimic the number. For example, the scientific notation of 104,000,000,000 would be 1.04 x 10^11, not 1.4 or 1.004. Your answer should be 4.092 × 10^11.

Which of the following points would be on the graph of the equation y=−4x+6?(−4, −10)(−4, 22)(1, −10)(1, −2)

suter [353]

Answer:

Only the point (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.

Step-by-step explanation:

Given the equation

$y=-4x+6$

Let us substitute all the given points to check which points satisfy the equation.

Substitute (-4, -10) in the equation

$y=-4x+6$

$-10=-4(-4)+6$

$-10=16+6$

$-10=22$

As the R.H.S ≠ L.H.S, hence (-4, -10) does not satisfy the equation.

Hence, (-4, -10) is NOT ON THE GRAPH of the equation

Substitute (-4, 22) in the equation

$y=-4x+6$

$22 = -4(-4)+6$

$22 = 16+6$

$22 = 22$

As the R.H.S = L.H.S, hence (-4, 22) satisfies the equation.

Hence, (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.

Substitute (1, -10) in the equation

$y=-4x+6$

$-10=-4(1)+6$

$-10=-4+6$

$-10=2$

As the R.H.S ≠ L.H.S, hence (1, -10) does not satisfy the equation.

Hence, (1, -10) is NOT ON THE GRAPH of the equation

Substitute (1, -2) in the equation

$y=-4x+6$

-2 = -4(1)+6

-2 = -4 + 6

-2 = 2

As the R.H.S ≠ L.H.S, hence (1, -2) does not satisfy the equation.

Hence, (1, -2) is NOT ON THE GRAPH of the equation

Therefore, from the above analysis, we conclude that only the point (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.
