For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
Answer:
y cannot be 3, 4, or 6
Step-by-step explanation:
If the function is to have an inverse, the y-values cannot be repeated. This means ...
y ∉ {3, 4, 6}
Hey there! :)
Triangles measure 180°
1 side = 100°
180 - 100 = 80
The measure of both unknown angles = 80°
Both are congruent, or the same. That means you have to divide by 2.
80 ÷ 2 = 40
? = 40°
Hope this helps :)
