10. Andrew Galen had a checking balance of $1.39 Monday morning. His net wages
of $512.89 were transferred by direct deposit at 11:00 a.m. to his checking
account. Later that evening, Andrew made online payments of $3.24, $18.30,
$38.96, $100.34, and $314.78. His goal is to keep only a $10 balance in his
checking account and have most of his money in savings. How much money
was available in Andrew's checking account to be transferred to savings after
all the transactions were completed?

Answers

$28.38

1.39 + 512.89= $514.28

3 + 18 + 38 + 100 + 314 = $473

.24 + .30 + .96 + .34 + .78 = $2.62

473 +2.62 = $475.62

514 - 475.62 = $38.38

38.38 - 10 = $28.38

Given that the points (-32,-10) and (-74,11) lie on a line, what is the equation of the line

Answers

The equation of the line with the points (-21, -10) and (-74, 11) is

y = (-/12)x - 26.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

(-32,-10) and (-74,11)

The equation of a line is given as,

y = mx + c

m = (11 + 10) / (-74 + 32)

m = 21 / -42

m = -1/2

Now,

(-32, -10) = (x, y)

-10 = (-1/2)(-32) + c

-10 = 16 + c

c = -10 - 16

c = -26

Now,

The equation of the line is y = (-/12)x - 26.

Step-by-step explanation:

When writing the number in standard form you have to look at the decimal point. If you already have a decimal point (like the question) then look for the first non-zero digit (in terms of the question, its 6). You have to move the decimal point to right until its after the first non-zero digit. Count how many spaces you moved, in this case its 7. If you are moving to the left you have to put a negative sign when writing the power of 10.
