Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.
One way to solve the system of equations would be to solve for q (in terms of r) in the first equation to get:
9r + q = 13
q = 13 - 9r
Then, take the value for q you just found and insert it into the second equation:
3r + 2(13-9r) = -4
Then simplify and solve:
3r + 26 - 18r = -4
-15r = -30
r = 2
Now that you have the value for r, plug it into either of the original equations and solve for q:
9r + q = 13
9(2) + q =13
18 + q = 13
q = -5
r = 2; q = -5
Answer:
Option A) is correct.
Step-by-step explanation:
The final cost of a sale item is determined by multiplying the price on the tag by 75%.
So. if the final cost is represented by $F and the price on the tag is $t, then the relation between F and t will be
F = 0.75t.
This relation is linear since the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
Therefore, option A) is correct. (Answer)
I think answer should be c. Please give me brainlest I hope this helps let me know if it’s correct or not okay thanks bye bye have a great weekend
