Using the foil method you get:
(2r*r) + (2r*-7) + (r*-2) + (-2*-7)
which is simplified to
2r^2 -16r + 14
Answer:
The number written in standard form is
Step-by-step explanation:
we have
we know that
substitute
Remember that
When multiplying decimals by 10, move the decimal point one space to the right
In this case move the decimal point eight spaces to the right
therefore
The number written in standard form is

Answer:
m= 4/5
Step-by-step explanation:
The equation of the line is in slope-intercept form.
y=mx+b
where m is the slope and b is the y-intercept.
Basically, the number that is being multiplied by x is the slope, and the number added or subtracted from that is the y-intercept.
We are given the equation:
y= 4/5x -3
4/5 is the coefficient of x. 3 is being subtracted from 4/5x.
Therefore, the slope of the line is 4/5 and the y-intercept is -3.
The question asks us to find the slope of the line, so the answer is 4/5.
You can take 8,000 and times it by 0.03. your answer is 2,500
