Answer:
D.
Step-by-step explanation:
The longer the interest rate, the more money it will generally cost someone.
Answer:
The costs of the plan are $0.15 per minute and a monthly fee of $39
Step-by-step explanation:
Let
x ----> the number of minutes used
y ----> is the total cost
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
we have the ordered pairs
(100,54) and (660, 138)
substitute
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Convert to slope intercept form
Isolate the variable y
therefore
The costs of the plan are $0.15 per minute and a monthly fee of $39
Answer:
B. 8x^2-6x-7
Step-by-step explanation:
All you have to do is combine the like terms.
Like terms are the terms that have the same variable and same exponent.
The like terms in this equation are 6x^2 and 2x^2, 11x and -17x, and -3 and -4.
When you add 6x^2 and 2x^2, you get 8x^2
When you add 11x and -17x, you get -6x
When you add -3 and -4, you get -7.
Putting these all in order, your answer is
8x^2 - 6x - 7
Answer:
Hi, I don't see an attachment with your question. But without any attachments to refer to. You use Pyrhagoras Theorem to solve this question.
Step-by-step explanation:
A^2 (Short side) + B^2 (Short side) = C^2 (Long side)

Answer:
y = 1.5x
Step-by-step explanation:
We are to find the equation of the straight line
Using the coordinate (0, 0) and (200, 300)
Slope m = 300-0/200-0
m = 300/200
m = 1.5
Since the line pass through the origin, the y intercept is 0
Substitute m = 1.5 and b =0 into y = mx+b
y = 1.5x + 0
y = 1.5x
This gives the required equation
