Answer:

y = -4x + 7

Step-by-step explanation:

Given points:

A(-2, -2) and B(6, 0)

The perpendicular bisector passes through the midpoint.

Finding the coordinates of the midpoint first:

x = (-2 + 6)/2 = 2, y = (-2 + 0)/2 = -1

Next finding the slope of AB:

m = (0 - (-2))/(6 - (-2)) = 2/8 = 1/4

The perpendicular lines have negative-reciprocal slopes.

The line will have a slope of -4 and pass through the point (2, -1)

y - (-1) = -4(x - 2)
y + 1 = -4(x - 2) - point-slope form
y = -4x + 7 - slope-intercept form

Answer:

2.09<2.1

Step-by-step explanation:

2.09 < 2.1

Take one number and subtract the other.

If you get a positive, then the first number is larger. If you get a negative, then the second number is larger.

I think 2.1 is larger

2.1

-2.09

-------------

Borrow from the 1

2. 0 10

-2. 0 9

---------------

0. 0 1

Since this is positive, 2.1 is larger

lidiya [134]

Answer:

The total of Charlie's be $7.

Step-by-step explanation:

Given:

Charlie and his friend Jay went to the fair. They were having a sale and the admission was 25% off.

The regular ticket price was $9.00.

And the tax is 6%.

Now, to find Charlie’s total.

So ,we deduct the 25% off first:

$\$9.00-25\%\ of\ \$9.00$

$=9-\frac{25}{100} \times 9$

$=9-\frac{225}{100}$

$=9-2.25$

$=\$6.75.$

Now, including tax :

$\$6.75+6\%\ of\ \$6.75$

$=6.75+\frac{6}{100} \times 6.75$

$=6.75+0.06\times 6.75$

$=6.75+0.405$

$=\$7.155.$

Approximately = $7.

Therefore, the total of Charlie's be $7.
