Answer:
80
Step-by-step explanation:
8 is 10% of 80 and this was 60% (logical I guess)
Five pairs of points (X,Y) that satisfy the equation Y=-2X+5 may be the following:
For X=0: Y=-2*0+5=5 (0,5)
For X=1: Y=-2*1+5=3 (1,3)
For X=2: Y=-2*2+5=1 (2,1)
For X=3: Y=-2*3+5=-1 (3,-1)
For X=4: Y=-2*4+5=-3 (4,-3)
The slope of the function is m=-2. Correct answer: C
Answer:1. Is right 3 down 5, because to get from x(0,0) to x'(3,-5), you need I shift to the right 3 and downwards 5.
2. Counterclockwise 180 degrees. This is because 180 degrees is half of a full rotation (360 degrees), meaning the point would be the same no matter which way you rotated 180 degrees.
3. Clockwise 90 degrees. Going counter clock wise 270 degrees is like going around 3/4 of a circle (because 270/360 is 3/4). Just as well, going clock wise 90 degrees is like going 1/4 of the circle, but in the opposite direction. This means they will both land at the same point.
Hope this Helps!
Step-by-step explanation:
Answer:
Step-by-step explanation:
y=x²-2x-1
and y=-3x+5
x²-2x-1=-3x+5
x²+x-6=0
x²+3x-2x-6=0
x(x+3)-2(x+3)=0
(x+3)(x-2)=0
x=-3,2
when x=-3
y=-3×-3+5=9+5=14
when x=2
y=-3×2+5=-6+5=-1
so solutions are (-3,14) and (2,-1)
B) (-4, -4)
When moving to the right you are moving to a more POSITIVE region on the x-axis; meaning, the y-value (vertical axis) does not get affected unless you’re moving up or down.
Remember: (-6, -4)
X = -6
Y = -4
If you move 2 units to the right (x-axis) you go from -6 + 2 which equals -4. And again, you’re not moving up and down so your
y-value stays the same and your new coordinates are (-4, -4)
