Answer:
(0,8)
Step-by-step explanation:
y = –2x + 8
The y intercept is found when x =0
y = –2*0 + 8
y = 8
The y intercept is
(0,8)
Answer:
no it doesn't because if the number in the first column increase then the number in the second column shouldn't be decreasing also the constant between 85 and 5 was 17 but the constant between 10 and 79 wasn't the same
14-8+5-2+6-11 is 4, therefore, the answer is A(4)
Answer:
A + B = 24
16A + 20B = 434
Step-by-step explanation:
To write a system of equations for this scenario, let's say that A represents the number of hours machine A ran, and B represents the number of hours machine B ran.
The first equation will be:
A + B = 24
because the total number of hours ran is 24.
The second equation will be:
16A + 20B = 434
because the total number of items made is 434.
A + B = 24
16A + 20B = 434
First solve for one variable, and let's just do A.
Using the first equation, A + B = 24, A is equal to 24 - B.
Substitute this value to the second equation.
16 (24 - B) + 20B = 434
384 - 16B + 20B = 434
4B = 50
B = 12.5
Now use this value of B to find the value of A.
A + 12.5 = 24
A = 11.5
Machine A ran for 11.5 hours, and Machine B ran for 12 hours.
