Answer:
5x - 2y = -2
Step-by-step explanation:
Slope: 5/2 and (-2,-4)
y-intercept= -4-(5/2)(-2) = 1
y = 5/2x+ 1
5/2x - y = - 1
2(5/2x - y) = -1*2
5x - 2y = - 2
Division I think It’s right not sure
Answer:
x = -3
Step-by-step explanation:
Okay, the first thing to do is get that 8 away from the fraction. How can we do it? When you have 2³ you have 8, is the same thing, so let's do it:
2³⁰/(2³)⁹ = 2^x
When you have a number with the shape (a^x)^y, you can write it as a^(x•y), so:
(2³)⁹ = 2^3•9 = 2²⁷
Now we have:
2³⁰/2²⁷ = 2^x
When you have a division like this: (a^x)/(a^y), you can write it as a^(x-y), so:
2^(30-27) = 2^x
2^-3 = 2^x
Now you know that x = -3
