Answer:
x =- 3 and y = -7
Step-by-step explanation:
2X-2Y=-8
X=2y + 11
We need to isolate both X and Y in both equations
so
2x-2y=-8
(add 2y to both sides)
2x=-8+ 2y
(divide both sides by 2)
x=-4+y and x=2y+11
because <u>both of these equations are the same </u>we can put them together
4+y=2y+11
(subtract y)
4=y+11
(subtract 11)
-7=y
so y = -7
then to find x you just need to plug in y to one of the equations
x=2(-7) + 11
x= -14 +11
x = -3
5(0)-4(0)^2+3
Answer:
=3
Best of wishes and good luck!!
Answer:
Step-by-step explanation:
Putting values of x in equation
Y = 4(-3) - 4
= - 12 - 4 = - 16
Y = 4(-2) - 4
= - 8 - 4 = - 12
Y = 4(-1) - 4
= - 4 - 4 = - 8
Y = 4(0) - 4
= 0 - 4 = - 4
Y = 4(1) - 4
= 4 - 4 = 0
Y = 4(2) - 4
= 8 - 4 = 4
Y = 4(3) - 4
= 12 - 4 = 8
The scale factor used is .5 because 7, 8, and 10 multiplied by .5 will equal 3.5, 4, and 5.
