Answer: a = 6
Step-by-step explanation:
The slope of the line is -1/2 so if y = -4, x = 6. In your case, x is a.
Hope this helps!
Answer:
D) 1 : 1
Step-by-step explanation:
Since it's 45-45-90 right triangle, it's an isosceles right triangle. An isosceles right triangle is a triangle that has two legs of equal length. So the ratio of the length of one leg to the length of the other leg is 1 : 1
Given:
Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).
To find:
The y-coordinate of the midpoint of line segment YZ.
Solution:
Midpoint formula:
The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:
Therefore, the y-coordinate of the midpoint of line segment YZ is -1.
The complete factored form of the quadratic expression is (x-8y)(x-8y)
<h3>Factorizing quadratic expression</h3>
Quadratic expressions are expressions that has a leading degree of 2
Given the expression
x^2 – 16xy + 64y^2
Factorize
x^2 - 8xy - 8xy + 64y^2
Group
(x^2 - 8xy) - (8xy + 64y^2)
x(x-8y) - 8y(x - 8y)
Since (x-8y) is common, hence;
x^2 - 8xy - 8xy + 64y^2 = (x-8y)(x-8y)
The complete factored form of the quadratic expression is (x-8y)(x-8y)
