Answer:
(B)Enlarge by scale factor of 3 about the origin. Then translate 1 right.
Step-by-step explanation:
For the end point (3,4)
- If we enlarge (3,4) by a scale factor of 3 about the origin, we have: (9,12)
- If we then translate 1 right, we have :(10,12)
Similarly for the end point (4,5):
- If we enlarge (4,5) by a scale factor of 3 about the origin, we have: (12,15)
- If we then translate 1 right, we have :(13,15)
The correct option is B.
Answer:
y + 3 = (1/2)(x + 2)
Step-by-step explanation:
The slope of the original path is -2. Any new path perpendicular to this one will have a slope which is the negative reciprocal of -2, which here is 1/2.
Use the point-slope formula y - k = m(x - h):
y - (-3) = (1/2)(x - (-2)), or
y + 3 = (1/2)(x + 2) represents the new path.
B=sqrt(7^2+15^2)
Hope it helps
Answer:
Step-by-step explanation:
(2 - 3)/(4 - 0) = -1/4
y - 2 = -1/4(x - 4)
y - 2 = -1/4x + 1
y = -1/4x + 3
Answer:
5
Step-by-step explanation:
Swap sides so that all variable terms are on the left hand side.
9r−11=34
Add 11 to both sides.
9r=34+11
Add 34 and 11 to get 45.
9r=45
Divide both sides by 9.
r= 45/9
Divide 45 by 9 to get 5.
r=5
