Answer:
h = -t+20
After 8 hours the candle will be 12 inches
Step-by-step explanation:
We have 2 points (time, inches)
(3,17) and (5,15)
We can find the slope
m = (y2-y1)/(x2-x1)
= (15-17)/(5-3)
= -2/2
= -1
We can use point slope form
y-y1 = m(x-x1)
Replace y with h and x with t
h-17 = -1 (t-3)
Distribute
h-17 = -t+3
Add 17 to each side
h-17+17 = -t+3+17
h = -t+20
Y=1.22x
y is the cost and x is kilometers driven. I got 1.22 by dividing 366 by 300 to find how it costs per kilometer.
Answer:
(5x^2+10x+1
)/x
Step-by-step explanation:
=(x/x)+9+5x+(1/x)
=(5x^2+10x+1
)/x
Answer:
5 cm and 13 cm
Step-by-step explanation:
Let b be the width of the rectangle.
Length = 3+2b
The area of the rectangle is 65 cm²
We need to find the dimensions of the rectangle. The area of a rectangle is given by :
A = lb

Neglecting the negative value, the width of the rectangle is 5 cm.
Length = 3+2b
=3+2(5)
=3+10
=13 cm
Hence, the dimensions of the rectangle are 5 cm and 13 cm.
Answer:
I put them in slop so
1) y= -2x+9
2) y=5/2x -9
it would help to say what u need to solve it for but hoped it helped
