Answer:
The correct option is;
90 degrees counterclockwise rotation
Step-by-step explanation:
The coordinates of the preimage before rotation = K(17, -12)
The coordinate of the image of the preimage after rotation = K'(12, 17)
Therefore, the rotation transformation, transforms, the preimage (x, y) to the image (-y, x), which is equivalent to a rotation of 90 degrees counterclockwise
Answer:
4.8%
Step-by-step explanation:
First turn it into a fraction. 60/1240. Than we can turn it into an equation 60/1240=x/100. Since 100 is the percent and x is what we need to find. And you now solve to get x=150/31 or 4.8
4.2 hours x .4 gallons per hour = 1.68 gallons
For number 9 just take the two functions and multiply or add them I can’t tell what sign that is
Answer:
m = -2
y-intercept = 4
Step-by-step explanation:
m = y2-y1/x2-x1
so
m = -2-4/3-0
=-2
y=mx+b
Substitute the coordinates into the equation to find b
4=-2(0)+b
4=b
so y intercept is 4
y=-2x+4
