For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following line:
The slope is 
By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to the given line will have a slope
Therefore, the equation of the parallel line will be of the form:
We substitute the given point and find "b":
Finally, the equation is:
Answer:
Answer:
There were 333 seniors in 1990
153 seniors had jobs in 2010.
Step-by-step explanation:
Let the number of high school seniors in 1990 = x
75% of x had jobs in 1990
In 2010 there were 50 more seniors. That is, the number of seniors is x+50.
40% of (x+50) had jobs in 2010.
Total number of jobs in both years = 403.
\[0.75 * x + 0.4 * (x + 50) = 403\]
\[0.75 * x + 0.4 * x + 20 = 403\]
=> \[1.15 * x = 403 - 20\]
=> \[1.15 * x = 383\]
=> \[x = 383/1.15\]
=> \[x = 333\]
Number of seniors having job in 2010 = 0.4 * (333 + 50) = 0.4 * 383 = 153.2 = 153(approx)
The yards of fabric needed is 45.50 yards.
<h3>How many yards of fabric is needed?</h3>
The first step is to determine the total inches of fabric that would be needed for 63 uniforms. The mathematical operation that would be used to determine this value is multiplication.
Multiplication is the process of determining the product of two or more numbers. The sign used to denote multiplication is ×.
Fabric needed for 63 uniforms = inches needed for one uniform x total number of uniforms
63 x 26 = 1,638 inches
The second step is to convert inches to yards
1 inch = 1/36 yards
1638 / 36 = 45.50 yards
Here is the complete question:
Mrs. Taylor is making new football uniforms for Fridays nights homecoming game. The trim for the sleeves of one uniform requires 26 inches of fabric. Mrs Taylor needs to make 63 uniforms total. How many yards of fabric should she buy?

Answer:
its the first on 5,3 can you give me brainliest
Step-by-step explanation:
Let x = the shorter piece and Let y = the longer piece.
(3/4)x = 120
x = 120 / (3/4)
x = 120 * (4/3 = 480/3) = 160 feet
y = 160 + 12
