Answer:
x-intercept equals 10
interpretation is that, after 10 hours, all of the snow will be melted
Step-by-step explanation:
First we solve for y₁
3×5 - 5y₁ = 20
15 - 5y₁ = 20
-5y₁ = 20 - 15
-5y₁ = 5
y₁ = -1
(5, -1)
Now we solve for x₂
3x₂ - 5×2 = 20
3x₂ - 10 = 20
3x₂ = 20 + 10
3x₂ = 30
x₂ = 10
(10, 2)
X + 5 = 3
Subtract both sides by 5
X = (-2)
They are not like terms. So false.
5x^2y is not the same as 7xy^2 because the exponent is on different variables.
