Answer:
Erica must score between 30 and 66 to obtain a grade average of C.
Step-by-step explanation:
We are given the following ion the question:
Erica's score:
86, 79, and 85
To get a grade C, the average score of Erica must lie between 70 and 79.
Formula:
Let x be the score on fourth test.
Thus, we can write:
Thus, Erica must score between 30 and 66 to obtain a grade average of C.
Answer:
The equation in point slope form is y - 1 = 3/2 ( x+3)
Option D is correct.
Step-by-step explanation:
We need to find the equation in point slope form of the line parallel to the given line in graph and passes through the line (-3,1)
The general form of point slope is:
y - y₁ = m(x-x₁)
We need to find the slope of the given line.
The formula used is:
m = y₂ - y₁ / x₂ - x₁
The points of the line are (2,2) and (-2,-4)
m = -4 - 2/-2-2
m = -6/-4
m = 3/2
Since the lines are parallel so, there slopes will be same. So slope m = 3/2
Now, finding the point slope form having slope m=3/2 and point (-3,2):
y - 1 = 3/2 (x - (-3))
y - 1 = 3/2 ( x+3)
So, the equation in point slope form is y - 1 = 3/2 ( x+3)
Option D is correct.
