What is 15+12x-5x+4y-7 by combining like terms

8+7x+4y

Step-by-step explanation:

15-7 is 8

12x-5x is 7

Put it all together to get 8+7x+4y

4y+7x+8

Step-by-step explanation:

First you combine any terms with y. There is only 4y so you write that down. Then, you combine the terms with x. 12x-5x=7x. Then, you combine the regular numbers so you get 8. Your final answer should be 4y+7x+8

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
