Answer:
a = 6
Step-by-step explanation:
7a-17 = 4a +1 ; Subtract 4a from both sides
3a - 17 = 1 ; Add 17 to both sides
3a = 18 ; Divide both sides by 3
a = 6
Answer:
C) (x,y) -> (-x,-y)
Step-by-step explanation:
This is the answer because the graph was flipped. If you look a the x point, it is in the same number, but the number is negative, and this is the same for the y point. hope this helps
Option A is correct.
Put the values of x in 3^x and you will get the answer corresponding to option A
Answer:
Step-by-step explanation:
the base of the vase will be where the vase touches the x-axis, that is 10 cm, therefore, the base is 10 cm from the wall
:
b) 25 = x^2 -20x +100, we solve for x to find the closest distance since as we move up the vase the distance to the wall gets closer(assume the y-axis is the wall), then
x^2 -20x +75 = 0 (x-15) * (x-5) = 0
x = 15 and x = 5
we reject x = 15
the shortest distance from the top of the vase to the wall is 5 cm
:
c) this is a left shift of the equation y = (x-10)^2
from b) we know that the left shift is 5 cm
10 - 5 = 5 cm from the wall to the base
:
d) y = (x-10+5)^2
y = (x-5)^2
