To estimate an answer to this problem, you must first estimate the numbers as well. 189 would round to 190, and 643 would round to 640. Now you would subtract 190 from 640, giving you 460.
Answer:
you don't give us the graph though
Step-by-step explanation:
give graph
The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.
f(0) = 9(0)^2 - 7 - 8(0)
f(0) = -7
Therefore the “y” coordinate would be -7
The ordered pair would be
(0, -7)
Answer:
Step-by-step explanation:
3(y + 2) = 14
3y + 6 = 14
3y = 14 - 6
3y = 8
y = 8/3 or 2 2/3
