Help with this one because I do not know how to do perpendicular plz put explanation with steps worth 50!

Answer:

Therefore, equation of the line that passes through (16,-7) and is perpendicular to the line $2x-3y=12$ is $3x+2y=34$

Step-by-step explanation:

Given:

$2x-3y=12$

To Find:

Equation of line passing through ( 16, -7) and is perpendicular to the line

$2x-3y=12$

Solution:

$2x-3y=12$ ...........Given

$\therefore y=\dfrac{2}{3}\times x-4$

Comparing with,

$y=mx+c$

Where m =slope

We get

$Slope = m1 = \dfrac{2}{3}$

We know that for Perpendicular lines have product slopes = -1.

$m1\times m2=-1$

Substituting m1 we get m2 as

$\dfrac{2}{3}\times m2=-1\\\\m2=-\dfrac{3}{2}$

Therefore the slope of the required line passing through (16 , -7) will have the slope,

$m2=-\dfrac{3}{2}$

Now the equation of line in slope point form given by

$(y-y_{1})=m(x-x_{1})$

Substituting the point (16 , -7) and slope m2 we will get the required equation of the line,

$(y-(-7))=-\dfrac{3}{2}\times (x-16)\\\\2y+14=-3x+48\\3x+2y=34......Equation\ of\ line$

Therefore, equation of the line that passes through (16,-7) and is perpendicular to the line $2x-3y=12$ is

$3x+2y=34$

Umberto buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill. Which is the best estimate of change he sho

Anika [276]

The change is the remaining money that is needed to take from the seller so a change of Umberto will be $6.62.

<h3>What is subtraction?</h3>

To subtract in mathematics is to take something away from a group or a number of objects.

The group's total number of items decreases or becomes lower when we subtract from it.

Given that,

Umberto buys a game for $7.89 and some batteries for $5.49.

Total money of buying = 7.89 + 5.49 = $13.38

Now he gives a $20 bill.

Remaining (change) = 20 - 13.38

⇒ $6.62

Hence "The change of Umberto will be $6.62".

Which of the following statements is true? a. A 30 year fixed mortgage will always result in the lowest payment. b. You must hav

saw5 [17]

Answer:

The correct answer is option C.

Step-by-step explanation:

The lower your interest rate is, the lower your monthly payments are. This is true. The interest rate is directly proportional to monthly or yearly payments. If the rates are high, the installments are high and if the rate of interest is low, the installments are lower.
