Answer:
y – 1= Three-halves(x + 3)
Step-by-step explanation:line goes through (-2, -4) and (2, 2)goes through (-3, 1)slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/21 = (3/2)*-3 + b1 = -9/2 + bb = 1 + 9/2 = 11/2 = 5.5y = (3/2)*x + 11/2(y - 1) = (3/2)(x + 3)-by
just flip the x,y by 90 and you get the answer
Y/5+7. When you evaluate, it will be 10
We can't do all those in one answer. I'll try the first page.
1 a. There are lots of ways to do these. They probably want you to see that the base of P is 4 units and the height is 6 units, so area (1/2)(4)(6)=12
Answer: 12
Let's try it with Pick's Theorem. Pick says interior points I count as 1 and boundary points B count as one-half, and we overcount by 1,
area = I + B/2 - 1
I count 9 interior points, I=9, and B=8 boundary points,
area = 9 + 8/2 - 1 = 12
Math works!
b. Q is a Parallelogram
c. Base 4, height 5, area = 4(5) = 20
2.
L=2W
P=2L+2W=24
2(2W)+2W=24
6W=24
W=4 cm
L=8 cm
I'll leave it to you to draw the 4×8 rectangle on the grid.
3.
L=3W
LW=48
(3W)W=48
3W²=48
W²=48/3=16
W=4
L=3W=12
4×12 rectangle to draw.
4.
b=2h
(1/2)bh = 16
(1/2)(2h)h = 16
h² = 16
h = 4
b = 8
Draw any triangle with base 8cm, height 4cm.
5.
b=2h
bh=50
2h²=50
h²=25
h=5
b=10
Parallelogram base 10, height 5
6.
That perimeter has 3 long sides of the rectangle and 3 short sides, and one extra piece that's the difference, 7-4=3cm.
P= 3(7+4) + 3cm = 36 cm
