Answer:

y = -1/7x - 23/7

Step-by-step explanation:

Step 1: Find slope <em>m</em>

m = (-4 + 3)/(5 + 2)

m = -1/7

y = -1/7x + b

Step 2: Find <em>b</em>

-3 = -1/7(-2) + b

-3 = 2/7 + b

b = -23/7

Step 3: Rewrite equation

y = -1/7x - 23/7

Help anyone<br> 8th grade math need it asap
Step2247 [10]

Answer:

The value of x = -13

Step-by-step explanation:

Given the expression

\frac{0.2x+1}{2}=-0.8

Multiply both sides by 2

\frac{2\left(0.2x+1\right)}{2}=2\left(-0.8\right)

simplify

0.2x+1=-1.6

Subtract 1 from both sides

0.2x+1-1=-1.6-1

Simplify

0.2x=-2.6

Divide both sides by 0.2

\frac{0.2x}{0.2}=\frac{-2.6}{0.2}

Simplify

x=-13

Therefore, the value of x = -13

A plumber charges a flat fee of $76 to visit a home and examine a clogged drain. The plumber charges an additional $24 per hour
prisoha [69]

Answer:

(a) 12 hours

(b) $220

Step-by-step explanation:

(a) First we plug in $364 for C

C=76+24h

364=76+24h

Subtract 76 from both sides

24h=288

Divide both sides by 24

h=12

She spent 12 hours fixing the drain

(b) First we plug 6 hours in for h

C=76+24(6)

Multiply it out

C=76+144

Add

C=220

It costs $220 for fixing a drain that takes 6 hours

Which of the following expressions are equivalent? Justify your reasoning,
marshall27 [118]

Answer:

B and D

Step-by-step explanation:

B:

Anything to a negative power means that it is 1/that to the positive power.

E.g. x^-1 = 1/x^1

In other words, anything to the power of a negative switches sides of a fraction (i.e. if in numerator moves to denominator and vice versa.)

1/x^-1 = 1/1/x^1 which is just equal to x, because there are x number of 1/xs in one (1/x * x =1) Therefore Option B is equal to just x.

D: (assuming the first given term is x^1/3 and not X1/3 (?) Correct me if I'm wrong).

x^1/3 * x^1/3 * x^1/3 is also equal to just x.

This is because when multiplying together terms with the same base (x in this case) the exponents just add together, so:

x^1/3 * x^1/3 * x^1/3 = x^(1/3 +1/3 +1/3) = x^1 = x.

Therefore B and D are equivalent because they both equal x.

Hope this helped!
