Answer:
(3/2, 6)
Step-by-step explanation:
y = 4x
8x + y = 18
this says y is 4x so you can replace y with 4x
8x + 4x = 18
12x = 18
/12 /12
x = 3/2
now sub x into y = 4(3/2)
y = 12/2
y = 6
Answer:
35
Step-by-step explanation:
If is given the value -8 as it is the input then -->
y = -4(-8) + 3
Negative four times negative 8 is positive 32 so
y= 32 + 3
And 32 plus 3 is 35
12h-9h=3h move everything else to other side
3h=20-40+6
3h=-14
divide by 3
h=-14/3
