Simply plug the number after the semi colon into each question's respective variable.
1. Is k=-1 a solution to this problem?
Is 9(-1)=10-(-1)?
we see that -9=10+1=11 which is not a true equality. since -9 is not 11 then "No" is the correct answer to number 1.
3.
3(-10)÷(-6)=5-(-10) ?
-30÷-6=5+10?
5=15?
No, not true, thus "No" is the correct answer.
5. 8-8=2(8)-16?
Is 0=16-16 ?
Yes!
7.
Is 2(7-2)-5(7)=5(2-7)?
2(5)-35=5(-5)?
10-35=-25
-25=-25
Bingo! Yes.

Answer: 3, 4, -4
If you multiply those 3, it equals -48. When you add them together, it's 3.
Every triangle has 180 degrees when you add there angles so you know that they will add up to 180
they are right triangles so the right angle has 90 degrees
so for the yellow triangle
90+45+x=180
135+x=180
45=x
we can tell where the purple and yellow triangle touch is 90 so 45+x=90 to find that angle which is 45
and the other one is 45
so there are two 90 degree angles and three 45 degree angles.
I hope that made sence
Answer:
x=-0.5, y=3.5
Step-by-step explanation:
The system consists of two functions equations.
Plot graph of each function (see attached diagram for details).
These graphs intersect at one common point. Its coordinates approximately are (-0.454,3.546).
This common point represents the solution of given system. The answer rounded to the nearest tenth is x=-0.5, y=3.5.
