Answer:
when x equals -3 y equals -23
when x equals 0, y equals -8
when x equals 3, y equals 7
when x equals 6, y equals 22
Step-by-step explanation:
14,000 is the correct answer
The generic equation of the line is:
Where,
m: slope of the line
(T0, H0): ordered pair belonging to the line.
The slope of the line is:
Substituting values we have:
Rewriting:
Then, choosing an ordered pair we have:
Substituting values we have:
Rewriting the equation:
Then, for 8 hours we have:
Answer:
a linear equation to model the relationship between height H of the candle, and T time is:
the candle will be 12 inches after burning 8 hours
Answer:
Solution given:
7x-29=2x+16[length from the circumference of circle is equal to same point]
7x-2x=16+29
5x=45
x=45/5=9
now.
XY=2×9+16=18+16=34 is your answer
Answer:
Step-by-step explanation:
a. The area of a rectangle is width * length. The width is 5x, and the length is 7x-2. This means the area is 5x*(7x-2). Distributing the 5x, we find that the area of the rectangle is 35x^2-10x.
b. To find the area when x is 4, we plug x=4, so 35*4^2-10*4=560-40=520.
c. same as above, we plug x=7, and get 1645 as our area.
