1.) y - 4 = -8(x - 1)

2.)y =^4 (Four is an exponent)

3.)y-x^2 = 4.5 (Two is an exponent)

4.)3x + 5y = 15

I need help A.S.A.P, any help is appreciated!

Answers

Answer 1

Answer: I would say that (4) and (3) are linear. hope this helps you ;)

Answer 2

Answer: 1.) and 4.) are linear equations.
3.) doesn't work because it has x^2 which makes it impossible for it to be linear(it will make it a parabola) and 2.) I an mot sure where x is and if 4 is an exponent where is the base. 1.) and 2.) work because if you put them in to slope form they Will make a line.
1.) y-4=-8(x-1)
y-4=-8x+8
y=-8x+12

2 ) 3x+5y=15
5y=-3x+15
y=(-3/5)x+3

these equations will make a line

What is 2.0124 rounded to the nearest thousandths?

Answers

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

2.0124 ≈ 2.012

Place of the thousandth digit in 2.0124 is the second 2. After rounding it to the nearest thousandths we'll get 2.012. It's because 2.0124 is closer to 2.012 than to 2.013.

Step-by-step explanation:

Which expression is equivalent to 11(17 – x)?A.

11 • 17 – 11x

B.

17 – 11x

C.

11 • 17 – x

D.

11 + 17 – x

Answers

The answer is A. 11 x 17 - 11x because you would use the distributive property and multiply the number on the outside (11) by everything on the inside (17 and -x)

for this, they are asking you to multiply both 17 and -x by 11. B and C only multiply one term by 11, and D doesn't multiply at all. A is the only one that fits!
