Answer:
25. Not a solution
26. Yes a solution
27. y= 2/3 x
28. y=3x+16
Step-by-step explanation:
25. The solution to a linear equation is the point (x,y). To find if an (x,y) is a solution, substitute it into the equation and see if it works.
y=4x-4 and (8,3)
3=4(8)-4
3=32-4
3=28
False
Not a solution.
26. Repeat 25 to solve 26 with y=5x-5 and (0,-5)
y=5x-5 and (0,-5)
-5=5(0)-5
-5=0-5
-5=-5
True
Yes a solution.
27. This line crosses through the origin is proportional and therefore has the form y=mx. It also has a gentle slant meaning that is less than 1/2 and goes in a positive direction. This means it is y=2/3 x.
28. Use inverse operations to rearrange the equation.
y-3x=16
y=16+3x
y=3x+16
Answer:
42
Step-by-step explanation:
42-6 = 36
36*2 = 72
72-40 = 32
32/4 = 8
The partial would be
40x5=200
2x5=10
210
Your just breaking them apart
X ÷ 4 = 8
Multiply each side by 4
x = 32
He subtracted 4 from 12 and got 8
Answer: 2250
Step-by-step explanation:
the smallest amount of money Carlos needs is 2250 because 750 is exactly 1/3 of 2250.
