Answer:
Midpoint={5.5,1}
Step-by-step explanation:
M={x1+x2/2,y1+y2/2}
M={6+5/2,-2+4/2}
M={11/2,2/2}
M={5.5,1}
The x remains the same while the y changes sign. So if it’s (1,4) the reflection will be (1,-4). Hope fully that helps.
Answer:
10
Step-by-step explanation:
isolate y by adding 5 to each side. Now you have y=x+10. 10 is the c value, which is the y-intercept
All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.
