Answer:
Step-by-step explanation:
y=mx+c
So in this case, m is (-3/7), which is the slope.
(-3/7)(another slope)=-1
Another slope=3/7
A. The slope is -7/3
B. The slope is 3/7
C. The slope is -7/3
D. The slope is -3/7
Thus, the answer is the bottom of the left hand side, which is 3x-7y=14
Hope it helps!!! Good luck!!
Answer:
x=-20
Step-by-step explanation:
3x+178=6x+238
-3x=60
x=-20
No, becasue of PEMDAS
so parenthasees first
exponents next
mulitplciation next
(-2)^4=-2 times -2 times -2 times -2=positive number since even number of negative signs
-2^4=-1 times 2^2=-1 times 2 times 2 times 2 times 2=negative number since odd number of negative signs
Simple way to see it is to multiply the value opposite of the axis you're flipping it over by -1. For example the point (-5,7) would become (5,7) when reflected over the y-axis, because the point is moving from the left to the right. This means the triangle would be (1,3) (5,3) and (5,7) when reflected over the y-axis. For reflection over the x-axis it would be (-1,-3) (-5,-3) and (-5,-7) because each point is moving down.
