Answer:
Andrew's test score if he got 8 questions wrong = 64 points
Andrew's test score if he got x questions wrong = 80 - 2x
Step-by-step explanation:
Total points of the multiple choice test = 80
Each question = 2 points
Total questions = Total points of the multiple choice test / 2 points
= 80/2
= 40
Total questions = 40
A. What would be Andrew's test score (out of 80) if he got 8 questions wrong
If he got 8 questions wrong out of 40 questions
= Total question points - wrong question points
= 40*2 - 8*2
= 80 - 16
= 64 points
Andrew's test score if he got 8 questions wrong = 64 points
B. What would be his score if he got x questions wrong?
Test points if he got x questions wrong = Total question points - wrong question points
= (40 * 2) - (x * 2)
= 80 - 2x
Andrew's test score if he got x questions wrong = 80 - 2x
Answer:
C
Step-by-step explanation:
Answer:
m=9,-9
Step-by-step explanation:
solve for m by simplifying both sides of the equation, then isolating the variable.
The equation is y = 3x+4.
<h3>What is equation?</h3>
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0
Given:
Customers pay $4 to enter the pumpkin patch.
customers pay $3 per pound for the pumpkins.
let $y be the total cost and there are x weight of pumpkins.
Now, cost of pumpkin for x pound,
= 3x
and the total cost y = 3x+4.
Hence, the equation is y = 3x+4.

Answer:
(0, 1)
Step-by-step explanation:
The angle (1/2)π radians is equivalent to 90°. Since angles are measured counterclockwise from the +x axis, an angle of 90° (or π/2 radians) is in the direction of the +y axis.
Your polar coordinates of 1∠(π/2) specify a point 1 unit up from the origin on the y-axis. The coordinates of that point are (x, y) = (0, 1).
