Answer:

-7 , -1

Step-by-step explanation:

if the equation of line p is

4x+7y=20 then the equation of line q must be

-7 x +4y=15 because perpendicular lines have

slopes with a product of -1

17x - y < 13
I’m slope-intercept form

Answers

Answer:

y > 17x - 13

Step-by-step explanation:

We want to write the inequality in slope-intercept form

The general slope intercept form is;

y = mx + b

where m is the slope and b is the y-intercept

So what we have to do to the inequality is to make y the subject

Thus, we have that;

17x -13 < y

Flipping this, we have

y > 17x-13

find the value of x.

Answers

Answer:

X= 20 degrees

Step-by-step explanation:

Because all the sides are the same length, we know this triangle is an equilateral triangle. In an equilateral triangle, all the angle measures are the same as well, and the sum of all the angles in a triangle is 180 degrees. So we have the equation:

(3x)3= 180

9x= 180

X =20

Find the slope of the line that passes through (-7, 1.3) and (-7, 14.2)

Answers

Answer:

The slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.

Step-by-step explanation:

Given the points

(-7, 1.3)(-7, 14.2)

Finding the slope between  (-7, 1.3) and (-7, 14.2):

It is clear that the value of x-coordinate remains the same, no matter what is the value of y is.

In other words, the given line is vertical.

i.e. [x₂ - x₁] = -7 - (-7) = -7+7 = 0

We know that the slope of a vertical line is undefined.

i.e.

Using the slope formula

Slope =  [14.2 - 1.3] / [0]

Hence, the slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.

Cant figure it out pls help

Answers

5y = -3x + 7

y = -3/5x + 7/5

Parallel = same slope

y = -3/5x + b

3 = -3/5 + b, b = 18/5

Standard form: Ax + By = C

y = -3/5x + 18/5

-3/5x - y = -18/5

Multiply by -5

Solution: 3x + 5y = 18

Answer: Scale factor = 2

This is the same as writing [tex]\frac{2}{1}[/tex]

===============================================

Explanation:

Focus on the left sides of each triangle. They correspond to one another. Note how RS represents the first two letters of RST; while MN represents the first two letters of MNO. We can see the order matters.

To find the scale factor, we divide MN over RS to get

MN/RS = 6/3 = 2

Therefore, the sides of triangle MNO are 2 times longer compared to the sides of triangle RST.

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

Extra info:

If you want to find x, then you would solve the following

MN/RS = ON/TS

6/3 = x/5.5

6*5.5 = 3x

33 = 3x

3x = 33

x = 33/3

x = 11

or we could simply multiply ST = 5.5 by the scale factor 2 getting 5.5*2 = 11, which is the length of segment ON.

Solve the inequality. Graph the solution. 3(-b - 5) < -3

Answer:

$1169.45

Step-by-step explanation:

Using the formula:

[tex]P = L \Big( \dfrac{c(1+c)^n}{(1+c^n) -1} \Big)[/tex]

where;

Loan amount L = 160000

number of months (n) = 20 × 12 = 240

Lets assume that the interest rate per month c = 6.25% since it is not given.

i.e. (6.25/( 100*12) ) = 5.208 × 10⁻³

∴

[tex]P = 160000 * \dfrac{5.208 *10^{-3} (1+5.208 *10^{-3})^{240}}{(1+5.208 *10^{-3})^{240}-1}[/tex]

P = $1169.45
