Answer:
13
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
p = ?
h = 10
b = 6
Now,
p2 = h2 - b2
p2 = ( 10)2 - (6)2
p2 = 100 - 36
p2 = 64
p = root under (64)
p = 8
Answer:
x=2/5, y=11/5
or x=−1y = 2
Step-by-step explanation:
Substitute y=3x+1 in x2+y2=5 to obtain
x2+(3x+1)2=5 ⇒ 10x2+6x−4=0
Hence
5x2+3x−2=0 ⇒ 5x2+5x−2x−2=0 ⇒5x(x+1)−2(x+1)= 0 ⇒ (5x−2)(x+1)=0
Hence
either
x=2/5, y=3×2/5+1=11/5
or x=−1, y=3×(−1) +1 = −2
The answer is A. “The dilation of 1/2 and Rotation of 90 or 270.”
Graph a.
3x+2y=12
-3x -3x
2y=-3x+12
2/2y=(3x+12)/2
y=-1.5x+6
graph b.
4x-y=5
+y +y
4x=y+5
-5 -5
4x-5=y
c) 11 units is the difference between y-coordinates of graph a and y-coordinates of graph b.
e) at (6,-3) x=6 cuts into graph a
