just add lol
Answer:
first and fourth
Step-by-step explanation:
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ±
= ± 2
that is x = - 2, x = 2
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ±
= ± 2
that is x = - 2, x = 2
Answer:
When y=2/5
(-y)^2= 4/25 and -y^2 = 4/25
When y =-2/5
(--2/5)^2 = 4/25 and -y^2 =4/25
Step-by-step explanation:
Answer:
Equation of a line is y = mx + c
where
m = gradient
c = y intercept
y = -5x + 3
Comparing this equation with the above formula
m = - 5
Since the lines are parallel their gradients are also the same.
So gradient of the parallel line is also 5
That's m = -5
Equation of the parallel line using point
(3, 1) and gradient m = -5 is
y - 1 = -5(x - 3)
y - 1 = -5x + 15
y = -5x + 15 + 1
Final answer is
y = -5x + 16
Hope this helps.
