When reflected across the y axis, the x coordinate becomes the opposite but the y coordinate stays the same, so N is (2, -5)
when reflected across the x axis, the y coordinate becomes the opposite but the x coordinate stays the same, so R is (2, 5)
Answer:
x = ⅘
Step-by-step explanation:
For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.
25x² = 16
divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5
Find the slope first
m = (y₂ - y₁)/(x₂ - x₁)
m = (4-2)/(5-0)
m = 2/5
Find the slope-intercept equation
y - y₁ = m(x - x₁)
y - 2 = 2/5 (x - 0)
y - 2 = (2/5)x
y = (2/5)x + 2
Answer:
x = -45, y = -40
Step-by-step explanation:
Based on the first clue, we find out that
x + 5 = y
5x = 6y + 15
We can re-write the first equation to x = y - 5.
Therefore, the second equation can also be written as 5(y - 5) = 6y + 15
This can be simplified to 5y - 25 = 6y + 15
We can subtract 6y from each side, and add 25 to each side;
5y - 6y = 15 + 25
Therefore, -y = 40
Therefore y = -40.
Now let's plug this back into the original equation, to get : x + 5 = -40
x=-45
