Answer:
3
Step-by-step explanation:
A + B is calculated by adding the same positions in both matrices.
and position (2, 3) in A+B is therefore the sum of position (2, 3) in A plus the position (2, 3) in B, which is then
-4 + 7 = 3
Answer:
55 degrees
Step-by-step explanation:
The sum of the measures of the angles of triangle is 180 degrees.
That allows you to find the value of x.
x + 25 + 30 = 180
x + 55 = 180
x = 125
To find y, use the fact that angles x and y are supplementary. The measures of two supplementary angles add to 180 deg.
y + x = 180
y + 125 = 180
y = 55
Answer: 55 degrees
An equation which has a graph that is parallel to the equation <span>9x + 3y = –22 should have the same slope as the given equation which is 3. Parallel lines are lines that do not meet or intersect at any point. They are characterized by having the same slope. For this case, any equation which has the slope of 3 will be parallel to the equation.</span>
