(-15, 0) and (-21, -2).
A) Do the lines intersect? Show work to prove it! Grcle YES or
NO

Answers

Answer:

Step-by-step explanation:

Find the slope of each line. If the slopes are the same, the lines are parallel. Otherwise, the lines intersect.

Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)

Slope of line passing through (0, 5) and (-6, 3) = (3-5)/(-6-0) = ⅓

Slope of line passing through (-15, 0) and (-21, -2) = (-2-9)/(-21-(-2)) = 11/19

The lines intersect.

Find the quotient. Write your answer in scientific notation, (3.6 x 10 to the power of 7) divided by (7.2 times 10 to the 7)

Answers

Given:

The given expression is:

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

To find:

The value of the quotient.

Solution:

We have,

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

It can written as:

[tex]=\dfrac{3.6}{7.2}\times \dfrac{10^7}{10^7}[/tex]

[tex]=\dfrac{1}{2}\times 1[/tex]

[tex]=0.5[/tex]

It can be rewritten as:

[tex]=5\times \dfrac{1}{10}[/tex]

[tex]=5\times 10^{-1}[/tex]

Therefore, the value of the quotient is [tex]5\times 10^{-1}[/tex].

Step-by-step explanation:

help please in this question?

Answers

Answer:

see explanation

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and are supplementary, sum to 180° , so

5x + x + 54 = 180 ← equation to solve to find x

6x + 54 = 180 ( subtract 54 from both sides )

6x = 126 ( divide both sides by 6 )

x = 21

Then

∠ 1 = 5x = 5 × 21 = 105°

∠ 2 = x + 54 = 21 + 54 = 75°

Solution:

Vowels are a, e, i, o, u.

In MATHEMATICS, the vowels are A, E, A, I.

Number of vowels = 4

We know that,

[tex]Probability=\dfrac{\text{Number of selected vowels}}{\text{Total number of vowels}}[/tex]

[tex]Probability=\dfrac{1}{4}[/tex]

So, the chance of drawing a vowel from letter tiles that spell out MATHEMATICS is [tex]\dfrac{1}{4}[/tex].

A rectangle has a length of y^2+3y+7 and a width of y-3. How much longer is the length?

Answers

Given:

The length of the rectangle = [tex]y^2+3y+7[/tex]

Width of the rectangle = [tex]y-3[/tex]

To find:

How much longer is the length?

Solution:

We need to find the difference between length and width of the rectangle.

[tex]Difference=Length-Width[/tex]

[tex]Difference=y^2+3y+7-(y-3)[/tex]

[tex]Difference=y^2+3y+7-y+3[/tex]

[tex]Difference=y^2+(3y-y)+(7+3)[/tex]

[tex]Difference=y^2+2y+10[/tex]

Therefore, the length of the rectangle is [tex]y^2+2y+10[/tex] much longer than the width.
