What is your question that you’ve been waiting for an answer to? I’ll try to help.
Answer:
x=9, y=0. (9, 0).
Step-by-step explanation:
y=-3x+27
6y-x+9=0
-----------------
6(-3x+27)-x+9=0
-18x+162-x+9=0
-19x+171=0
-19x=0-171
-19x=-171
19x=171
x=171/19
x=9
y=-3(9)+27=-27+27=0
In this question, you're trying to find the unit rate in which the teacher can grade tests.
A unit rate is another word for "rate of change".
This means that we have to find how many tests the teacher could grade in 1 minute.
To find the unit rate, divide 18 by 15
18 ÷ 15 = 1.2
This means that Mr. Rivera can grade 1.2 tests in 1 minute.
Answer:
1.2 tests
