The dependent variable is f(m)...total money earned per day
the independent variable is m...number of miles

f(m) = 3.5m + 65

for 40 miles..
f(40) = 3.5(40) + 65
= 140 + 65
= 205 <== money earned for the day
========================
the dependent variable is f(p)....total charged
the independent variable is p...the number of pounds

f(p) = 3.5p

for 5 lbs...
f(5) = 3.5(5)
f(5) = 17.50 <== total that was charged

Write an equation in slope-intercept form for the line parallel to y = 5x - 2 that passes through the point (8, -2).

steposvetlana [31]

Answer:

$y = 5x - 42$

Step-by-step explanation:

The equation of parallel line differ only by their constant.

Hence, the equation of the line parallel to $y = 5x - 2$ is nothing but $y = 5x + c$

When a point passing through this line is given we can substitute the point in this line and get the value for $c$ .

The line passes through $(8 , -2)$ .

Therefore, we have: $-2 = 5(8) + c$

$\implies c = -42$ .

Substituting this we get the equation of the parallel line as $y = 5x - 42$ .

Write 2/15 as a decimal.

Cloud [144]

If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
$\frac{2}{15} = \frac{x}{10}$

now let's multiply both sides by 10:
$\frac{20}{15} = x$
and simplyfy:
(by dividing the first fraction's elements by 5)
$\frac{4}{3} = x$

change improper fraction into a mixed number
$1\frac{1}{3} = x$

and 1 over 3 is 0.33333...

so the answer is 1.333333 - we can also write it as 1.(3)

1. (5,8) m= 3 It wants me to write this in slope intercept form

ikadub [295]

Answer:

The answer is: y = 3x - 7

Step-by-step explanation:

Given point: (5, 8).

Slope m = 3

Use the point slope form and solve for y:

y - y1 = m(x - x1)

y - 8 = 3(x - 5)

y - 8 = 3x - 15

y = 3x - 15 + 8

y = 3x - 7

Proof:

f(x) = 3x - 7

f(5) = 3(5) - 7

= 15 - 7 = 8, giving (5, 8)

Katy used 3/4 of a 6 ft board for a science fair project. How many inches did she use?

adoni [48]

She used 54 inches. 3/4 is equal to .75 so you can find 3/4 of the board by taking the fool length and multiplying it by .75 so 6•.75=4.5. So 3/4 of the board is 4.5 ft. However, the answer has to be in inches so since there are 12 inches in a foot you multiply 4.5•12 and that gives you your answer:54 inches.
