What is the y-intercept and x-intercept for the equation -3x - 4 = -5y - 8
BARSIC [14]

Step-by-step explanation:

=> -3x - 4 = -5y - 8

=> 8 - 4 = 3x - 5y

=> 4 = 3x + (-5)y

=> 1 = (3x/4) + (-5y/4)

=> 1 = x/(4/3) + y/(-4/5)

Compare this with x/a + y/b = 1 where a and b are x & y intercepts.

Here,

x intercept = 4/3

y intercept = -4/5

Adding and subtracting fractions with different denominators :D
Korolek [52]

Answer:

find the LCM of denominators and multiply the last answers of LCM for example take 1/3 and 1/2 it's LCM is 6

1/3 = 1×2/3×2 = 2/6

1/2 = 1×3/2×3 = 3/6

then subtract 3-2/6 = 1/6 this is subtraction

instead of subtracting just add it

Which are the solution of x2 =-5x +8
Salsk061 [2.6K]

Answer:

x=6/5 or 1.2

Step-by-step explanation:

I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both

2= -5x+8 (next subtract 8 from both sides)

-6= -5x (divide both sides by -5)

-6/-5=x (the negative cancel out next)

6/5 or 1.20 is x

If your original problem should say 2x=-5x+8

2x=-5x+8 (add 5x to both sides next)

7x=8 (divide by 7 on both sides)

x=8/7
