Y = mx + c
y = 2x + c
When x = 5 and y = 0,
0 = 2(5) + c
c = -10
y = 2x - 10
Well you don't have to subtract it you can also simply the expression
7i-16i
And you'll get 4-33i
Hopefully this helps you !
To solve this, we’ll have to use inverse operations.
Since addition is the inverse to subtraction, we’ll add 20 to 620.
20 + 620 = 640
From there, since division is the inverse of multiplication, we’ll divide .75 by 640.
640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.
Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)
Hope this helps! :)
Answer:
21.4
Step-by-step explanation:
took the quiz
8x²-18xy-5y²
8x²+2xy-20xy-5y²
2x(4x+y) -5y (4x+y)
= (2x-5y) (4x+y)
