Answer:
(-2, 3)
Step-by-step explanation:
The point B is:
B(x,y)
x
AB(A to B) is twice BC(B to C)
AB is 2 - x. BC is x - (-4) = x + 4.
So
2 - x = 2(x + 4)
2 - x = 2x + 8
3x = -6
x = -2
y
Same logic as above.
AB is -5 - y. BC is y - 7.
-5 - y = 2(y - 7)
-5 - y = 2y - 14
3y = 9
y = 3
The point is (-2, 3).
Answer:
$3.85
Step-by-step explanation:
First, we need to find out what we need to divide 24.64 by to get the price of 1 gallon.
If 6.4 gallons costs $24.64, then we can divide 6.4 by 6.4 to get 1.
Now we have to divide 24.64 by 6.4 too, to find out how much it costs for 1 gallon.
24.64/6.4=3.85
It costs 3.85 to buy 1 gallon.
Hope this helps!
4)
Non linear:
y = 6 -x^2
y = 2x^2 + 2
y = x^3
5)
Rate of change is also the slope
= (72 - 69) / (51 - 48)
= 3/3
= 1
Rate of change = 1
6)
First you need to find slope
(3,0) and (5,2)
Slope = (2 - 0)/(5-3) =2/2 = 1
Equation
y - 0 = 1(x - 3)
y = x - 3
Answer:
Tyler's function is correct as y = x - 3, it matched the above.
