Answer:
y = 2x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = 6 + c ⇒ c = - 4 - 6 = - 10
y = 2x - 10 ← equation of line
Answer: (7 + d) 4 and 4 (7 + d)
Step-by-step explanation:
<em>4 (d + 7) = 4d + 28</em>
<em />
(7 + d) 4 = 28 + 4d (flipped version of 4d + 28)
4 (7 + d) = 28 + 4d (the same)
Answer:
n= 36
Step-by-step explanation:
18=n-18 (add 18 to both sides of the equation, 18 and -18 cancel out)
36=n
Answer:
This is a vertical line, that passes through x=-2
Step-by-step explanation:
This is a vertical line, x=-2 means that no matter what value has 'y' the variable 'x' will be -2.
Watch the attached picture
f(x) = 1 - ²/ₓ₃
y = 1 - ²/ₓ₃
y = 1 - ²/ₓ₃
y - 1 = ⁻²/ₓ₃
x - 1 = -2/y³
y³(x - 1) = -2
y³ = ⁻²/ₓ₋₁
y = ∛⁻²/ₓ₋₁
y = -∛(2x² - 4x + 2)/x - 1
f⁻¹(x) = -∛(2x² - 4x + 2)/x - 1
