Find the missing value so that the two points have a slope of 3/2 (0,y) and (2,-2)
Harlamova29_29 [7]

Answer:

y = -5

Step-by-step explanation:

To find the slope , we use

m = (y2-y1)/(x2-x1)

3/2 = (-2-y)/(2-0)

3/2 = (-2-y)/2

Since the denominators are the same, the numerators have to be the same

3 = -2-y

Add 2 to each side

3+2 = -2-y+2

5 = -y

Divide each side by -1

5/-1 = -y/-1

-5 = y

Solve the compound inequality<br> 3t-8/5 and 4-t&lt;-7
Sav [38]

Answer: -2.8

Step-by-step explanation:

3t-(8/5) * 4-t < -7

(15t-8)/5 * 4-t < -7

((15t-8)(4-t))/5 < -7

(15t^2)-28t-32< -7

(15t^2)-28t-32-7< 0

(15t^2)-28t-39< 0

Using the quadratic/almighty formula

t= (-b +- ((b^2)-4ac)^(1/2)/2a)

a=15, b=-28, c=-39

t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))

t= -2.8 or t= 0.9

Since

t<0, then t= -2.8

Neil has 3 partially full cans of white paint.They contain 1/3 gallon, 1/5, gallon, and 1/2, gallons of paint About how much pai
stepan [7]

Answer:

1 and 1/30 gallons

Step-by-step explanation:

First, convert all the fractions to a common denominator. I'm choosing 30.

1/3=10/30  1/5=6/30  1/2=15/30

Now, you can add them together to get 31/30, so a little more than a gallon
