Erin has written three tests for her math class. She calculates the average of hermarks on the first two tests. This average is
asambeis [7]

To obtain an overall average of 86%, a score of 96 is required on her 4th test.

Let the required score on her fourth test = t

The required average = 86%

Initial scores : 80% + 83.5% + 84.5%

Average = ΣX/ (fx)

fx = total score obtainable = 4 × 100 = 400

ΣX = sum of scores

Average = 86%

0.86 = ((80 + 83.5 + 84.5 + t) / 400)

86 = (248 + t) / 400

400 × 0.86 = 248 + t

344 = 248 + t

344 - 248 = t

96 = t

In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

What is an equation of the line that passes through (2,2) and is parellel to the line y=7x
laila [671]

Answer:

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Step-by-step explanation:

Given:

a line y=7x

To Find:

Equation of line passing through ( 2, 2) and is parellel to the line y=7x

Solution:

y=7x     ...........Given

Comparing with,

y=mx

Where m =slope

We get

Slope = m = 7

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.

Now the equation of line in slope point form given by

(y-y_{1})=m(x-x_{1})

Substituting the points and so we will get the required equation of the line,

(y-2)=7(x-2)=7x-14\\\\y=7x-12......Equation\ of\ line

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12
