Answer:
The answer is A
Step-by-step explanation:
2t(t-4)
(2t x t)(2t x -4)
2t^2 - 8t
Answer:
y=3(x+8)+1 or y=3x+25
Step-by-step explanation:
Make the problem into y=mx+b (standard form) by adding 1 to both sides. Then you can simplify 3(x+8)+1 into 3x+25 by distributing and combining like terms. then graph starting from the y-intercept 25 and use the slope of 3 or 3/1 to plot the points around the y-intercept. then draw the graph. :3
Answer:
256/81
Step-by-step explanation:
According to the formula:
Using the above formula to solve the question, we perform following steps:
=
=
=
which is the required answer.
4(5x-20)=-20
20x-80=-20
20x=60
x=3
Mr. Blue' salary is an illustration of a geometric sequence
- The explicit rule of Mr. Blue 's salary is an = 30000 * 2^(n - 1)
- The recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000
<h3 /><h3>How to determine the explicit formula?</h3>
Mr. Blue's salary is a geometric sequence with the following parameters:
First term, a1 = 30000
Rate, r = 2
The explicit rule is calculated as:
an = a1 * r^(n - 1)
This gives
an = 30000 * 2^(n - 1)
<h3>How to determine the recursive formula?</h3>
The common ratio is calculated as:
r = an+1/an
Substitute 2 for r
2 = an+1/an
Cross multiply
an+1 = 2an
Hence, the recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000
