Answer:
Step-by-step explanation:
You get the slope right away, just by reading it.
y = 1/4 x + b
To solve for b, you use the point 4,5
5 = 1/4 * 4 + b Substitute 4 for x
5 = 1 + b Subtract 1 from both sides
5-1 = 1-1 + b
b = 4
The line is y = 1/4 x + 4
The length of the line on the blueprint of the wall will be 18 inches.
Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
There is no effect of dilation on the angle.
An architect uses a scale of 3/4 inches to represent 1 foot on a blueprint for a building.
Then the scale factor of the blueprint will be
Scale factor = 3/4 inches per foot
If the east wall of the building is 24 feet long.
Then the length of the line on the blueprint of the wall will be
Length = 24 feet x scale factor
Length = 24 x (3/4)
Length = 6 x 3
Length = 18 inches
Thus, the length of the line on the blueprint of the wall will be 18 inches.

Answer:
16 in.
Step-by-step explanation:
We have the ratio
How about let's make this easier. Easier is better, right? Let's get rid of the fraction 2/3. We will do that by multiplying 2/3 by 3 and 1 by 3 to get the equivalent ratio of
Now we need to know how many inches there would be if the number of feet is 24:
Cross multiply to get
3x = 48 so
x = 16 in.
Answer:
(0,0) and (1,4)
Step-by-step explanation:
you want to have the same slope as
y=4,which is 4.
so(4-0)/(1-0)=4/1=4
The others do not have the same slope.
Answer: The cost per minute is $0.13 or 13 cents.
Step-by-step explanation:
If it charges $15 for 120 minutes then to get to one minute we will have to divide it by 120.
so 15/120 = 0.125 which rounds to 0.13 to the nearest cent.

6v = 18
6 6
v = 3
Answer:
8/t + t^2 = 18
Step-by-step explanation:
8/t + t^2
t = 4
8/4 + 4^2
2 + 16 = 18
8/t + t^2 = 18
