Recognize that parallel lines have the same slope. Then:
Method 1: write y = 2x + c and find c from the given information:
y = 2x + c becomes 0 = 2(-2) + c, so that c = 4. Then y = 2x + 4 (answer)
Method 2: Slope is 2 and a point on the line is (-2,0):
Use the point-slope formula: y - 0 = 2(x+2), or y = 2(x+2), or y=2x+4 (ans)
A or c am not completely sure I am 90% sure or is I
Answer:
y = (√7)/4
Step-by-step explanation:
The equation of the unit circle is ...
x^2 +y^2 = 1
Putting the given value in for x, we can find y to be ...
(-3/4)^2 +y^2 = 1
y^2 = 1 -(-3/4)^2 = 1 -9/16 = 7/16 . . . . . subtract 9/16
y = √(7/16) . . . . . . . . . . . take the square root; y > 0 here
y = (√7)/4
Perimeter is legnth +legnth + width + width or
P=2L+2W
L=2W
subsitute L=2W for L in P=2L+2W
P=2(2W)+2W
P=4W+2W
P=6W
we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width
subsitute W=5 for W in L=2W
L=2(5)
L=10
to check
10=2(10)+2(5)
30=20+10
30=30
checks
Legnght=10
Width=5
