For the solid line it is (0,-3), (0,3), (-3,4)
for the dotted line it is (-1,-1), (-3,-2), (-3,2)
hope this helps don't know for sure though if its right i just did the best i could do.
Answer:
the shape, or point translates eight squares left and three squares up.
Step-by-step explanation:
Answer:
(2, 4)
Step-by-step explanation:
Given the system of equations
y=3×-2.... 1
y-2=× ... 2
Substitute 2 into 1
y = 3(y-2) - 2
y = 3y - 6 - 2
y - 3y =-6-2
-2y = -8
y = -8/-2
y = 4
Recall that
x = y - 2
x = 4-2
x = 2
Hence the solution (x, y) is (2,4)
Answer:
The dimensions are 4 millimetres by 10 millimetres
Step-by-step explanation:
The area of the first rectangle is 5*8=40 square millimetres. Let's call the width of they yellow rectangle w, and the length l. Now you can set up the following system of equations:
l*w=40
2l+2w=28
Isolate one of the variables to substitute:
l=40/w
2(40/w)+2w=28
80/w+2w=28
Multiply both sides by w:
80+2w^2=28w
Move everything to one side:
2w^2-28w+80=0
Factor the quadratic:
2(w^2-14w+40)=0
2(w-10)(w-4)=0
w=4 or 10
l= 10 or 4
Hope this helps!
