What is the slope of y-4=5/2(x-2)
OLEGan [10]
The answer is 5/2. The equation is already in point slope form. If you recall, the equation for point slope form is y-y1 = m(x-x1) where y1 and x1 are points on the graph, and m is the slope. In the given equation, m is 5/2 so we know it is the slope.
Alternatively, if you are not familiar with the point slope for equation, you can manipulate the equation to the form of y=mx+b where m is the slope and b is the constant. If you solve for y, you get y=5/2x-1 since 5/2 is in the place of m, we know 5/2 is the slope.

Caleb is making a soil mix that is 8 parts dirt to 3 parts peat moss. Which of the following best describes the amount of dirt h
Ierofanga [76]

Answer:

D. He should add between 2 cups and 3 cups of dirt.

Step-by-step explanation:

First we need to take the ratio of dirt to peat moss.

8 parts dirt : 3 parts peat moss.

Now we take the ratio and find the value of dirt.

8 : 3 = \dfrac{8}{3}

x : 1 = \dfrac{x}{1}

\dfrac{x}{1} = \dfrac{8}{3}

We now multiply both sides by 1.

1\dfrac{x}{1} = 1\dfrac{8}{3}

x = \dfrac{8}{3}

x = 2.67

So now we substitute x.

2.67 Cups Dirt : 1 Cup Peat Moss

REY [17]
Given: h/9 - 12 = -4

Add 12 on both sides:

h/9 = 8

Multiply 9 on both sides:

h = 72
