1 answer:

6 0

Answer: Linear

Explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Find the solution to the system of equations.

harina [27]

Answer:

x=2

y=3

Step-by-step explanation:

y=−2x+7

y=5x−7

Set the two equations equal since they are both equal to y

−2x+7 =5x−7

Add 2x to each side

-2x+7+2x = 5x-7+2x

7 = 7x-7

Add 7 to each side

7+7 = 7x-7+7

14 =7x

Divide by 7

14/7 = 7x/7

2 =x

Now find 7

y = 5x-7

y = 5(2) -7

y = 10-7

y = 3

Find the sum of 7a^3 + 14a +12 and -6a^3 +12a^2 -7

SOVA2 [1]

To find the sum:

${7a}^{3} + 14a + 12 + ( {- 6a }^{3} ) + {12a }^{2} - 7 \\ = {7a }^{3} - {6a}^{3} + {12a }^{2} + 14a + 12 - 7 \\ = {a}^{3} + {12a }^{2} + 14a + 5$
Therefore the answer is a^3+12a^2+14a+5.
Hope it helps!
