x - y = - 11 .............( 1 )
y + 7 = - 2x ...............( 2 )
from equation ( 1 )
x - y = - 11
x = -11 + y ...........( 3)
putting x in equation ( 2 )
y + 7 = - 2 x
y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7
3 y = 15 y = 15 / 3
putting value of y in equation 3
x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)
x = -17 / 5
check
x = -11 + y
- 17 / 5 = -11 + 13 / 5
-17 /5 = -17 / 5

Step-by-step explanation:
Answer:
q(x) = 0.005 (x - 40)∧2 + 70
Step-by-step explanation:
If you mean with "up" that function is translated along the y axis
in that case the correct answer is:
q(x) = 0.005 (x - 40)∧2 + 70
God with you!!!
The expression for the square of a binomial is
Since your expression starts with 
It means that 
, and so -6x must be twice the product of x and some number b. If you choose b = -3 you have
So, if you add 8 to both sides of your equation, you have
By choosing one sign at a time, we have the two solutions
