4x-9y=9

Mathematics
1 answer:
Alexxandr [17]3 years ago
5 0
Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.

Second equation:
-x + 3y = 6

Multiply the second equation by 4 on both sides:
-4x + 12y = 26

What is the coefficient of q in the sum of these two expressions? (23q – 34) and (–16q – r) NEED HELPPP
jeyben [28]

Answer:

The coefficient of q is 7

Step-by-step explanation:

The two expressions are

23q-34 and -16q-r.


The sum of the two expressions is


23q-34+-16q-r


When we group like terms the expression will be,


=23q-16q-r-34


When we  simplify the expression will now be


=7q-r-34

The coefficient of q is the constant behind q in the expression.

The coefficient of q is  therefore 7.

Please help, question in pic
Ray Of Light [21]

Answer:

D

Step-by-step explanation:

hard to explain but when you rotate 180, you can imagine that a straight line with the center of rotation as the midpoint can be drawn between the image and preimage. you want a mapped to c and you want d mapped to b. having it rotate 180 with the center of rotation being the center of the parallelogram allows you to make those imaginary lines between a and c and d and b. hope this helps
