Which of the following is the inequality −18x + 2y ≥ −13 written in slope-intercept form?
Elena L [17]
Hey there! :) 

We're simply just trying to convert "-18x + 2y ≥ -13" into slope-intercept form.

First, we need to know what slope-intercept form is.

Slope-intercept form is : y=mx+b , where m=slope and b=y-intercept.

In order to convert our given equation into slope-intercept form, we have to isolate "y." 

We can do this by adding 18x to both sides.

2y ≥ 18x - 13

Then, divide both sides by 2.

2y ÷ 2 = (18x - 13) ÷ 2

Simplify.

y = 9x - 13/2

Convert -13/2 into a mixed fraction.

So, simply divide -13 by 2.

-13 ÷ 2 = -6.5

Plug in -6.5 into where -13/2 was.

y = 9x - 6.5

Therefore, your answer is C : y ≥ 9x - 6.5

~Hope I helped!~

For the equation 5x + 36 = x, which value could be a solution
Bess [88]
5x+36=x 
4x+36=0 Subtract x from both sides
4x=-36 Subtract 36 from both sides
x=-9 Divide both sides by 4
The answer is -9.

If a coin is thrown with a starting velocity of 0 m/s down a dry well and hits bottom in 1.2 s, what's the depth of the well?
BigorU [14]

Answer:

H=7.0632m

Step-by-step explanation:

Since, a coin is thrown with velocity "u"=0m/s and time "t"=1.2s,it gains an acceleration due to gravity, then using the formula, H=ut+\frac{1}{2}gt^{2};

Since u=0 and g=9.81, therefore,

H=\frac{1}{2}(9.81)(1.2)^{2}

H=\frac{1}{2}(9.81)(1.44)

H=\frac{14.1264}{2}

H=7.0632m
