Write the equation of a line that is perpendicular to the given line and that passes through the given point.
HACTEHA [7]
First, let's re-arrange to slope-intercept form.

x + 8y = 27

Subtract 'x' to both sides:

8y = -x + 27

Divide 8 to both sides:

y = -1/8x + 3.375

So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.

So the slope of the perpendicular line will be 8.

Now we can plug this into point-slope form along with the point given.

y - y1 = m(x - x1)

y - 5 = 8(x + 5)

y - 5 = 8x + 40

y = 8x + 45

2% of the students at Hamilton Middle School have red hair. There are 700 students at Hamilton Middle
Makovka662 [10]

Answer:

14 students

Step-by-step explanation:

We can set up a percentage proportion to find 2% of 700.

\frac{x}{700} = \frac{2}{100}, and we can use the cross products property to find the value of x.

700\cdot2=1400\\\\1400\div100=14

Hope this helped!

bongo had a balance of $345.28 in his checking account. During the week amounts: $65.08, $24.50, and $118.95. He then made a dep
vichka [17]

Answer: 192.75

Step-by-step explanation:

I am answering your question assuming that the three amounts were checks that were written out during the week.

Beginning balance = 345.28

Subtract the total amount of the checks (65.08 + 24.50 + 118.95 = 208.53)

345.28 - 208.53 = 136.75

Next, add the amount of the deposit. 136.75 + 56.00 = 192.75
