Answer:

Step-by-step explanation:
1) Expand by distributing terms.

2) Simplify 4*3x to 12x.

3) Simplify 4*2y to 8y.

<u>Therefor, the answer is </u><u>12x + 8y.</u>
12 out of 30 % because if you add 12+20+8= it equals 30 and they said there are 12 blueberry muffins.
We can infer for the graph that the solution of the system of equation is the point (0,4).
The point (0,4) is the solution of the system of equations because their graphs intercept at that point.
As a bonus, we can also infer for the graph that our system of equations is:
Answer:
37° and 53° respectively.
Step-by-step explanation:
We need to know that the angles are complementtary if ∠RSU + ∠UST = 90°. Then,
5x+7 + 9x-1 = 90
5x + 9x +7 -1 = 90
14x +6 = 90
14x = 90 - 6
14x = 84
x = 84/14
x = 6.
Then, the angle ∠RSU has measure 5(6)+ 7 = 30+7 = 37, and the angle ∠UST has measure 9(6) - 1 = 54-1 = 53.
