3x+4y=36
2x-y=2
<em><u> </u></em><em><u>=</u></em><em><u>x-7y</u></em><em><u>=</u></em><em><u>3</u></em><em><u>4</u></em>
The answer for the first one is 4 the sacend one is 49/2 the thirst one is 33223
Answer:
Step-by-step explanation:
perp. -5
y + 7 = -5(x - 4)
y + 7 = -5x + 20
y = -5x + 13
Answer:
B. m ∠ 1 = 90° and m ∠ 2 = 90°
Step-by-step explanation:
For most situations, the conjecture would probably be true, but there is one exception that makes this statement false.
When two right angles are supplementary, none of them is acute.
For an angle to be acute it needs to be lesser than 90°, and for a pair of angles to be supplementary they should add up to exactly 180°.
With a pair of right angles (90° each), their sum adds up to 180° but neither of them are acute.
Therefore, the answer is B. m ∠ 1 = 90° and m ∠ 2 = 90°
Answer:
Below.
Step-by-step explanation:
One example is a square.
Another is a rectangle.
Both of these contain 4 right angles.
