Answer:
(-3, 3)
Step-by-step explanation:
y = x + 6
y = -2x - 3
x+6= -2x-3
3x = -9
x = -3
put x = -3 : y = -3+6 =3
Answer: m<VUT= 70 degrees
Step-by-step explanation:
120= 50+ ?
?=70
OK the next step is to multiply 3r -1 by -7r
this gives us -21r^2 + 7r and we write it below -21r^2 + 25r
and subtract
This gives us 18r and we bring down the -6 to give
18r - 6
Finally we divide 18r by -3r to give -6 then add - 6 to the r^2 - 7r on the top
then multiply -3r - 1 by -6 to give 18r - 6
subtraction then leaves nothing.
so the answer is r^2 - 7r - 6
