Answer:
(2x-7y) (2x+7y)
Step-by-step explanation:
4x^2−49y^2
This is the difference of squares
a^2 - b^2 = (a-b) (a+b)
a^2 =4x^2 so a = 2x
b^2 = 49y^2 so b =7y
4x^2−49y^2 = (2x-7y) (2x+7y)
Step-by-step explanation:
x=-2+y
7(-2+y)+2y=-5
-14+7y+2y=-5
9y=9
y=1
x=-2+1
x=-1
Answer:
p = 17/48 or 0.354
Step-by-step explanation:
11/16 = p + 4/12
subtract 4/12 from both sides
11/16 - 4/12 = p
convert so you have a common denominator
3(11/16) - 4(4/12)
33/48 - 16/48
= 17/48
p = 0.354
Slope m= (y2-y1)/(x2-x1)=(8-0)/(2-(-2))=8/4=2
y=mx+b
y=2x+b
Take the point (-2,0)
0=2*(-2)+b
b=4
y=2x+4=2(x+2)
Answer is A. y=2(x+2)
