He should have added 1 to both sides to make the -1 on the right go to 0.
Then it would be 0 + m = -16 + 1 = -15
You can check your work by adding -1 and -15, which does in fact equal -16.
Hope this helped :)
Answer:
91 2/7
Step-by-step explanation:
because gcf of 639 and 7 is 91 and then just simple math
M= (7-1)/(2-0)=3
y=3x + c
plug in Q
1= 3 x 0 +c
=> c =-2
=> the equation represents line QR is y=3x -2
Answer: 5/2
Explanation:
According to 30-60-90 triangle rule:
The side opposite of 30 degree is equal to half of the hypotenuse and the hypotenuse here is 5 so therefore x = 5/2
We know that
scale factor=measure triangle DEF/measure triangle ABC
DE/AB=DF/AC=EF/BC
12/72=7/42=11/66-----> 1/6
the answer is
<span>the scale factor of ABC to DEF</span> is 1/6
