what is the slope of (-1,-1) and (1,5)?? Please help me!!!

Answers

Answer:

Slope is 3.

Step-by-step explanation:

Slope is change in y to change in x:

$\displaystyle{\text{slope} = \dfrac{\Delta y}{\Delta x}}\\\\\displaystyle{\text{slope} = \dfrac{y_2-y_1}{x_2-x_1}}$

In mathematics, slope is generally declared as "m" variable.

Also, we are given two coordinate points. Let $x_1$ be -1, $x_2$ be 1, $y_1$ be -1 and $y_2$ be 5.

Therefore:

$\displaystyle{m = \dfrac{5-\left(-1\right)}{1-\left(-1\right)}}\\\\\displaystyle{m=\dfrac{5+1}{1+1}}\\\\\displaystyle{m=\dfrac{6}{2}}\\\\\displaystyle{m=3}$

Therefore, the slope is 3.

The slope of (-1,-1) and (1,5) is three

Step-by-step explanation:

$ \sf{ - 3 \frac{1}{3} \div 9}$

Convert the mixed number into improper fraction

$ \longrightarrow{ \sf{ - \frac{ 3 \times 3 + 1}{3} \div 9}}$

$ \longrightarrow{ \sf{ - \frac{ 9 + 1}{3} \div 9}}$

$ \longrightarrow{ \sf{ - \frac{ 10}{3} \div 9}}$

Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

$ \longrightarrow{ \sf{ - \frac{ 10}{3} \times \frac{1}{9}}} $

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator

$ \longrightarrow{ \sf{ - \frac{10 \times 1}{3 \times 9}}} $

$ \longrightarrow{ \sf{ - \frac{10}{27}}} $

Find a completely simplified expression for the perimeter (2 ⋅ length + 2 ⋅width) of the blue rectangle:

Answers

Answer: 18x-12

Step-by-step explanation:

2(6x+2+3x-8)

2(9x-6)

18x-12

The perimeter of the shown rectangle is given by the equation:

P = 2*(6x + 2)*(3x - 8)

How to get the perimeter?

For a rectangle of length L and width W, the perimeter is:

P = 2*(L + W).

Here we have:

L = 6x + 2

W = 3x - 8

Replacing that in our equation, we get:

P = 2*(6x + 2)*(3x - 8)

So the perimeter is given by the above quadratic equation.

Plot 2 1/3, −5/6, and −3 1/2 on the number line.

Plotting fractions on a number line

When plotting fractions on a number line, we need to figure out how much each tick mark is. See the photo attached for how to plot 2 1/3, –5/6, and –3 1/2 on the number line.

The number line

On a number line,

the left side shows smaller numbers, and;the right side shows greater (bigger) numbers.

This number line also has negative numbers. Each tick is still worth the same on the entire number line, but leftward of 0, the numbers become negative.

How much is each tick mark?

The vertical markings on the number line are called tick marks.

To get from one whole number to the next whole number on the number line, we have to count 6 tick marks. This means that each tick is 1/6.

Plot 2 1/3

The dot will be between 2 and 3.

First, find 2.

$\frac{1}{3} =\frac{1*2}{3*2}=\frac{2}{6}$ Since 1/3 = 2/6, we then move right (get bigger) by 2 ticks.

See the photo below for the plotted dot. 2 1/3 is in red.

Plot –5/6

The dot will be between -1 and 0.

Start at 0. Then, move left (get smaller) by 5 ticks.

See the photo below for the plotted dot. – 5/6 is in green.

Plot –3 1/2

The dot will be halfway between –3 and –4.

First, find –3. Then, move left (get smaller) by 3 ticks.

See the photo below for the plotted dot. –3 1/2 is in blue.

At what point does the graph of 3x + 4y = 15 intersect the graph of x^2 + y^2 = 9? Express any non-integer coordinate as a common fraction.

Answers

Answer

12 and 36 and 13

If you need an explanation;

let's first isolate x in 3x + 4y = 15 ---

x = (15 - 4y) / 3

now substitute as x in the second equation provided ---

((15 - 4y) / 3)^2) + y^2 = 9,

((15 - 4y) / 3)^2) +( 3y/3)^2 = 9,

((15 - 4y)^2 + (3y/3)^2)/3^2 = 9,

225 - 120y +25y^2/9 = 9,

225 - 120y +25y^2 = 81,

25y^2 - 120y + 144 = 0

we now solve using the quadratic formula ---

$y_{1,\:2}=\frac{-\left(-120\right)\pm \sqrt{\left(-120\right)^2-4\cdot \:25\cdot \:144}}{2\cdot \:25}\\=\frac{-\left(-120\right)\pm \sqrt{0}}{2\cdot \:25}\\=\frac{-\left(-120\right)\pm \sqrt{0}}{2\cdot \:25}\\\\= 12/5$

So then x = (15 - 4*12/5)/3 = 9/5. Our solution = (9/5, 12/5)
