Answer:

y=35x−9

Step-by-step explanation:

Step 1: Add -12x to both sides.

12x−20y+−12x=180+−12x

−20y=−12x+180

Step 2: Divide both sides by -20.

−20y−20=−12x+180−20

y=35x−9

The distance between them is

[tex]d = \sqrt{ ({ - 6 - 2})^{2} + ({ - 5 - 0})^{2} } \\ = \sqrt{ ({ - 8})^{2} + ( { - 5})^{2} } \\ = \sqrt{64 + 25} \\ = \sqrt{89} \: \: \: \: \: \: \: \: \: \: \\ = 9.4339811[/tex]

Answer:

4/5

Step-by-step explanation:

If two lines are parallel, then they have the same slope. So, we first need to put the equation in slope intercept form (y = kx + b)

8x - 10y = -60

-10y = -8x - 60

y = 4/5x + 6

So the slope is 4/5.

Answer:

In slope intercept form -5y = -4 - 30

Step-by-step explanation:

Slope intercept form is y=mx + b

Rewrite your equation in this form

-10y = -8x - 60

Find GCF (Greatest Common Factor) in this case it is 2

Divide all by 2

-5y = -4x - 30

Answer:

The equation is 36d = 28,000, or 36 x d = 28,000.

Answer:

[tex]2\sqrt[4]{3}[/tex]

Step-by-step explanation:

[tex]48^\frac{1}{4} = \sqrt[4]{48} = \sqrt[4]{2*2*2*2*3} = 2\sqrt[4]{3}[/tex]

The given expression can be written in simplest radical form as 2[tex]\sqrt[4]{3}[/tex].

In order to write an exponent in radical form, first take the prime factors of the given number and then put the remaining numbers that are left out in the radical form.

The given expression is [tex]48^{1/4}[/tex].

The prime factorization of 48 gives 48 = 2 × 2 × 2 × 2 × 3

It can be written in simplest radical form as follows,

[tex]48^{1/4}[/tex] = [tex](2 \times 2 \times 2 \times 2 \times 3)^{1/4}[/tex]

        = 2 × [tex]3^{1/4}[/tex]

        = 2[tex]\sqrt[4]{3}[/tex]

Hence, the radical form of given expression is 2[tex]\sqrt[4]{3}[/tex].

Answer:

x=-26

Step-by-step explanation:

Answer:

Hi there!

Your answer is:

x= -26

Step-by-step explanation:

3(x+4) = 2(x-7)

First, distribute 3 to the first parentheses and 2 to the second parentheses.

3x +12 = 2x-14

Next, get all whole numbers on the right side

3x +12 = 2x-14

-12

3x = 2x -26

Then, get all the X's on the left side

3x = 2x -26

-2x

x= -26

Answer:

Step-by-step explanation:

probability ∈[0,1]

or probability ≥0

and ≤1

so a,b,g cannot be the probability of an event.

Answer:

See Explanation

Step-by-step explanation:

The probability of an event ranges from 0 to 1.

So, the options c. 0.6, d. 0.888, e. 0 and f. 0.39 represents the probability of an event.

Probability of an event cannot be negative number or more than 1.

Hence, options a. - 1, b. 4.2, g. - 0.5 does not represent the probability of an event.

Answer: y=-6/5x+3

Step-by-step explanation:

To find the equation of the line that passes through the points, you want to first find the slope by using the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], then solve for the y-intercept.

[tex]m=\frac{15-(-3)}{-10-5} =\frac{18}{-15} =-\frac{6}{5}[/tex]

Now that we have the slope, we can plug in a given point and solve for the y-intercept.

15=-6/5(-10)+b        [multiply]

15=12+b                   [subtract both sides by 12]

b=3

Now that we have the y-intercept, we know the equation is y=-6/5x+3.

The midpoint of the given line is (3,-3.5)

The midpoint of a line is a point which divides the line segment into two equal parts.We can also say that a midpoint bisects a line segment.

We know when two end points of a line segment are given we can find midpoint by

M(x) = (x₁ + x₂)/2 and M(y) = (y₁ + y₂)/2.

Given points  C(-2, 5) and D(8, -12)

M(x) = ( - 2 + 8 )/2

M(x) = 6/2

M(x) = 3.

M(y) = ( 5 - 12 )/2

M(y) = -7/2

M(y) = -3.5.

Answer:

if x is what you are looking for then, x = 30

Step-by-step explanation:

3x - 40 = x + 20 (they are vertically oppositel

2x = 60

x = 30

Answer:

x = 30

Step-by-step explanation:

The 2 given angles are vertical and congruent, thus

3x - 40 = x + 20 ( subtract x from both sides )

2x - 40 = 20 ( add 40 to both sides )

2x = 60 ( divide both sides by 2 )

x = 30
