Answer:20%
Step-by-step explanation:85 times 5 equals 425 100 divided by 5 is 20
Answer:
x = 0
y = 5
z = -5.
Step-by-step explanation:
X-5y-z=-20
-2x-y-6z=25
-x-4y-z=-15
Add equation 1 and 3:
-9y - 2z = -35 .......... A
Multiply the first equation by 2:
2x - 10y - 2z = -40
Now add this to equation 2:
-11y -8z = -15.............B
Now multiply equation A by -4:
36y + 8x = 140.........C
Add equations B and C:
25y = 125
y = 5.
Substitute for y in equation A:
-9*5 - 2z = -35
2z = -45 + 35 = - 10
z = -5.
Now find x by substituting for y and z in the first equation:
x - 5(5) - (-5) = -20
x - 20 = -20
x = 0.
Answer:
Step-by-step explanation:
so i plugged this into a graphing calculator.. maybe it's not fair to use technology :D
vertex (1,-9)
y intercept = -8
line of symmetry is x = 1
BECAUSE
4(2x)= 8x
4(1)= 4
SO
4+8x= 4(2x+1)
