Answer:The equations are equivalent so there are an infinite number of solutions.
Step-by-step explanation:
Answer: yes
Step-by-step explanation: slope is 4/3 and y intercept is 8
m= Y-20/0-9
4/3= y-20/-9
4/3 x -9 = y-20
-12 = y-20
Y=20-12
Y=8
Answer:
1. y-(is that a 7 or a 1?) = 2(x-4)
2. y-4 = (1/2)(x-2)
3. y = (2/3)(x+6)
... and so on
The formula for a line given point and slope is :
y - (y-value of point) = slope * x - (x-value of point)
Answer:
390cm³
Step-by-step explanation:
IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.
All you need to do is solve for the volume of each prism and add them up together.
The formula to use to get the volume of a rectangular prism is:

Where:
V = Volume
w = width
l = length
h = height
Let's get the first one and double it because you have rectangular prisms with the same dimensions:

Next we get the rectangular prism in the middle:
Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.
12cm - (5cm + 2cm)
12 cm - 7cm = 5cm
Then we plug it into the formula

Now that we have the volumes of all figures, just add them up together:
150cm³ + 240cm³ = 390cm³
