Answer:
y = 2 - 5/4x
or
y = 2 - 1.25x
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. Let's make this equation look more like that by isolating y on one side.
5x + 4y = 8
Subtract 5x from both sides.
4y = 8 - 5x
Divide both sides by 4.
y = 8/4 - 5/4x
y = 2 - 5/4x
Answer: 1 3/5
Step-by-step explanation:
5/5 = 1
There is a remainder of 3/5.
Combine these two pieces to get the whole, 1 3/5.
Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
First you divide everything by 4 which will become b^2+2b-3=0
Then you can factor this which is
(b-1)(b+3)=0
B=1
B=-3 ... I think that's how you do it
