Y=6x-11
the slope of the original line is 6. the slope of a line perpendicular would be a negative inverse, so the slope of the perpendicular line is -1/6
Answer:
44
Step-by-step explanation:
crop the square into two, then you can see tangent which is 90°.
so, 360-90-90-136=44
Answer:
6%
Step-by-step explanation:
6 squares of the whole are shaded
There are 100 total squares
Write as a fraction
6/100
Write as a percent (the fraction is already out of 100, so just write the numerator with a percent sign)
6%
Hope this helps :)
He gets an average between 80 and 90
It is between these two values
So it could be 80 or higher but it must be 90 or belowe so it can be equal to 80 or above and it can be equal to 90 or below
This gives two inequalities 80 ≤ x and x ≤ 90
This can be written as 1 inequality 80 ≤ x ≤ 90
≤ this means less than or equal to the one that points the opposite way would be greater than or equal to think of it as a number line pointing right is positive meaning the numbers get bigger, getting greater pointing left is getting smaller so it gets less and less
5(4x-3)^2 - 3
5(16x^2 - 2(3)(4x) + 9) -3
5(16x^2 - 24x + 9) -3
80x^2 - 120x + 45 - 3
80x^2 - 120x + 42
80(0)^2 - 120(0) + 42
42
