Answer:
10
Step-by-step explanation:
give brainliest please!
hope this helps :)
so these two angles add up to 180 degrees
7x -3 + 12x -7 = 180
7x+12x=180+7+3
19x=190
x=10
to check if this is true we can input 10 for x in each side.
7(10)-3 = 67
12(10)-7 = 113
113+67 = 180
40 mowers = $4,776
Multiply the above equation by 3
120 mowers = $14,328
Answer: B. (-4, 0)
<u>Step-by-step explanation:</u>
The question is: when is the <u>function</u> constant?
function is also called f(x), which is also called "y".
So the question is asking: when is the y-value constant?
the y-value is constant (not increasing or decreasing) between x = -4 and x = 0. So the interval is (-4, 0)
Answer:
9
Step-by-step explanation:
6.4(x)+2.8y=44.4
6.4(3)+2.8y=44.4
19.2+2.8y=44.4
2.8y=25.2
y=9
