Answer:

y = 3/8 x -3

Step-by-step explanation:

3x - 8y = 24

Solving for y

Subtract 3x from each side

3x-3x - 8y =-3x+ 24

-8y = -3x+24

Divide each side by -8

-8y/-8 = -3x/-8 +24/-8

y = 3/8 x -3

Answer:

y=\frac{3}{8} x-3

Step-by-step explanation:

To solve for y, we want to isolate it. This means subtracting 3x from both sides:

-8y = 24 - 3x

Now, to get y, we divide both sides by -8 to get rid of the current coefficient of y:

y=\frac{24-3x}{-8} =-3+\frac{3}{8} x

Thus, the answer is y=\frac{3}{8} x-3 .

Hope this helps!

If GHJ is equal to LMK, with a scale factor of 5:6, find the perimeter of GHJ.
xxTIMURxx [149]

Answer:  Weeeell,  35

Step-by-step explanation:

1. By definition, the perimeter of a triangle is the sum of the lenght of each side.

2. Then, the perimeter of the triangle LMK is:

P_{LMK}=14+17+11\\P_{LMK}=42

3. If both triangles are congruent and the scale factor is 5:6 (Which you can rewrite as a fraction: 5/6), you must multiply the perimeter of the triangle   LMK by this scale factor.

4. Then, you have that the perimeter of the triangle GHJ is:

P_{GHJ}=42*\frac{5}{6}=35

A mix of factoring by grouping. Factor the exressions. 17ax+17a-x-1 Please explain/show steps on how to do this!
mario62 [17]

Answer:

(x+1)(17a-1)

Step-by-step explanation:

We are given that

17ax+17a-x-1

We have to factorize the given expression.

Pair up the terms

(17ax+17a)+(-x-1)

Now, taking common factor

17a(x+1)-1(x+1)

Taking common (x+1)

(x+1)(17a-1)

Now, we get

(x+1)(17a-1)

This is required factors of given expression.
