Answer:
-2x-7y=-4
Step-by-step explanation:
5x+-7x=-2x
-9y+2y=-7y
1+-5=-4
So -2x-7y=-4
Answer: True
Step-by-step explanation:
A subset is a term used in the sets topic In mathematics to describe a Part of A larger values being considered.
Sample In experimental procedures is known as Part of what is to be used to determine the reaction of a larger mass of specimen.
Taking these two definitions by side, it is quite evident that both of them represent taking part of a larger picture to form a smaller picture which does not totally deviate from the larger picture being considered.
Answer:
12a + 6
Step-by-step explanation:
given 3(4a + 2)
multiply each term in the parenthesis by the 3 outside ( distributive law )
= (3 × 4a ) + (3 × 2 ) = 12a + 6
Given: c | | d, m 4 = m 5
Prove: m 7 = m 8
1. c||d, m∠4=m∠5
GIVEN
2. m∠4 = m∠7
If lines ||, alternate interior angles are equal.
3. m∠5 = m∠8
Vertical angles are equal.
4. m∠7 = m∠8
Substitution
It could be x > 21 im not sure
