Hi there!
The change of y-values is
- 15 - 22 = - 37
The change of x-values is
7 - - 8 = 7 + 8 = 15
Therefore, the slope of this line is
The first statement is true.
The second statement is false.
The third statement is true.
3d + 8 = 2d - 7 equals d = -15.
First, subtract 2d from both sides. Your problem should look like: 3d + 8 - 2d = -7.
Second, simplify 3d + 8 - 2d to get d + 8. Your problem should look like: d + 8 = -7.
Third, subtract 8 from both sides. Your problem should look like: d = -7 - 8.
Fourth, simplify -7 - 8 to get -15. Your problem should look like: d = -15, which is your answer.
Hopefully this helps, I'm not exactly sure what you meant by "is equations," but this is how you solve the problem.
Pq= 10.5, qr=31.5, rs=10.5, sp=31.5
7 goes into 357 51 times. First you take 35 and see how many times 7 goes into that and that is 5 than you take 7 and see how many times 7 goes into that and that is 1 time so that you take your to answers and you get 51 as the final answer.
