The answer is -3, Choice 1 because you only need to care about the x values, so what do you add/subtract from 8 you get 5? So the answer is -3

Answer:

A) -3

Step-by-step explanation:

Given,

When (8x + 12y) is added to (ax − 6y) the answer is (5x + 6y)

(8x+12y)+(ax-6y)=(5x+6y)

8x+12y+ax-6y=5x+6y

(8+a)x+6y = 5x+6y      ( By combining like terms )

By comparing,

8+a = 5

\implies a = 5 - 8 = -3

Hence, the value of x is -3,

Option A is correct.

Which linear function represents the line given by the point-slope equation y – 2 = 4(x – 3)?
patriot [66]

y = 4x - 10. The linear functions y = 4x - 10 represent the line given by the point-slope equation y - 2 = 4(x - 3).

In order to solve this problem, we have to take the point-slope equation y - 2 = 4(x - 3) and convert it to the linear function form y = mx + b as follow:

y - 2 = 4(x - 3)

y - 2 = 4(x) - (4)(3)

y - 2 = 4x - 12

y - 2 + 2 = 4x -12 +2

y = 4x - 10 (Linear function)

Find the area of a square with 6 1/2
koban [17]

Answer:

I'm guessing the 6 1/2 means the length of one side so you would just multiply 6 1/2*6 1/2 and that equals 42.25 (or 169/4)

Two equations are given below: m + 4n = 8 m = n - 2 What is the Solution ?
Sophie [7]
M+4n=8
m=n-2
we see that m=n-2
so we can subsitute 'n-2' for m in the first equation
(n-2)+4n=8
n-2+4n=8
5n-2=8
add 2 to both sides
5n=10
divide by 5
n=2
subsitute
n=2
m=n-2
m=2-2
m=0

m=0
n=2

the answer is c. 0,2
