2)76*100=80x
x=95
3) 96*100=160x
x=60
4)85*120=100x
x=102
5)56*100=75x
x=74.66
Answer:
(1, 1) is the only one on the graph
Step-by-step explanation:
To determine if an ordered pair lies on the graph, substitute the x-coordinate of the ordered pair into f(x) and evaluate. If the value equals the y-coordinate of the ordered pair then it lies on the graph
f(1) = (2 × 1) - 1 = 2 - 1 = 1 ⇒ (1, 1) lies on graph
f(- 1) = (2 × - 1) - 1 = - 2 - 1 = - 3 ≠ - 4 ⇔ (- 1, - 4 ) not on graph
f(- 2) = (2 × - 2) - 1 = - 4 - 1 = - 5 ≠ - 
⇒ (- 2, - ) not on graph
f(0) = (2 × 0) - 1 = 0 - 1 = - 1 ≠ 
⇒ not on graph
This is the graph, I hope it helps
Answer:
6. (2,1) 7. (2,2)
Step-by-step explanation:
Number 6, Since it is a dilation of .5 you divide the x and y coordinate by 2 to get (2,1). X - 4/2=2, Y - 2/2=1
Number 7, Since it's rotating 90 degrees counterclockwise you switch the x and y coordinates. So from (x,y) to (y,x) and also when going counterclockwise you have to make the y coordinate becomes negative, so the counterclockwise equation is (-y,x) plug in your numbers and you get (2,2) as your 90 degree counterclockwise rotated coordinates.
Find the length the width and the height and then divide by 3 and you’ll get your answer
