The first step in isolating z would be multiplying both sides by 4 to cancel out the fraction
after that you have
4x = 2y - z
subtract 2y
4x - 2y = - z
divide both sides by -1 to completely isolate z
-4x + 2y = z should be your answer
Answer:
Step-by-step explanation:
Solve the y
y -3 = 1/2(x + 2)
y = 1/2(x + 2) + 3 Add
Pick points that you wish to substitute for x values.
x = 0 x = 2 x = 4
y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3
y = 1/2(0 + 2) + 3 y = 1/2(2 + 2) + 3 y = 1/2(4 + 2) + 3
y = 1/2(2) + 3 y = 1/2(4) + 3 y = 1/2(6) + 3
y = 1 + 3 y = 2 + 3 y = 3 + 3
y = 4 y = 5 y = 6
Locate the following point on graph (x, y); (0, 4), (2, 5), (4, 6)
13. # books * 2
97 * 2
A
14. 4.5 km/21 min = 7.5 km = x min
cross multiply
4.5x = 7.5(21)
4.5x = 157.5
x = 35 min
B
15. 9.60/12 = x/4
cross multiply
12x = 4(9.60)
12x = 38.40
x = 3.20
C
16. 18% move decimal two places to the left and drop the % sign
0.18
A
17. d = rt
d = 2(55)
d = 110 miles
150 - 110 = 40 miles remaining
A
Answer:
$1380 is left of the check
Step-by-step explanation:
2300 times .40 is 920
920 minus 2300 is 1380
( IF THIS IS CORRECT CAN I GET BRAINLYEST)
Step-by-step explanation:
to find the x intercept make y =0
6x - 2(0) = 12
6x = 12
x= 2
x intercept (2,0)
to find y intercept make x=0
6(0) - 2y = 12
-2y = 12
0= 12 + 2y
-12 = 2y
y= -6
y intercept (0,-6)
