19. Find the equation of the line that contains the given points. Write the equation in slope-
intercept form, if possible.
(-5,-5) and (1,7)
Please solve step by step

A function shows the relationship between at least two variables. There are several ways to represent a function; some of them are:

Tables

The following table shows the relationship between two variables x and y

[tex]\left[\begin{array}{cccccc}x&1&2&3&4&5\\y&2&4&6&8&10\end{array}\right][/tex]

Equations

Notice that the y values of the above table are twice the corresponding x-values.

So, the equation can be represented as:

[tex]y = 2x[/tex]

Graphs

See attachment for the graph of [tex]y = 2x[/tex]

Verbal

As stated above, the value of y is twice the value of x.

The above statement is a verbal representation of a function

Hence, a function can be represented with a table, graph, equation and verbally.

Answer:

the first option is the answer, r = √6

Step-by-step explanation:

[tex]hypotenuse = \sqrt{opposite {}^{2} + adjacent {}^{2} } [/tex]

hypotenuse = q = √12

adjacent = p = √6

opposite = r

substitute the values into the hypotenuse formula

[tex]q = \sqrt{r {}^{2} + p {}^{2} } [/tex]

[tex] \sqrt{12} = \sqrt{r {}^{2} + ( \sqrt{6} ) {}^{2} } [/tex]

[tex]( \sqrt{12} ) {}^{2} = r {}^{2} +6[/tex]

[tex]12 = r {}^{2} + 6[/tex]

[tex]12 - 6 = r {}^{2} [/tex]

[tex]6 = r {}^{2} [/tex]

[tex] \sqrt{6} = r[/tex]

Answer:

(9x + 8y + 24) trees

Step-by-step explanation:

The total amount of trees the students planted is calculated as:

Amount of trees planted on Saturday + Amount of trees planted on Sunday

= 2(3x + 4y) + 3(x + 8)

= 6x + 8y + 3x + 24

= 6x + 3x + 8y + 24

= 9x + 8y + 24

Hence, the total amount of trees the students planted was (9x + 8y + 24) trees

Answer:

[tex]m=\frac{2A-kn}{k}[/tex]

Hence, option C is true.

Step-by-step explanation:

Given the expression

[tex]A=\frac{k}{2}\left(m+n\right)[/tex]

Solving for 'm'

[tex]A=\frac{k}{2}\left(m+n\right)[/tex]

Flip the equation

[tex]\frac{k}{2}\left(m+n\right)=A[/tex]

Expanding by applying the distributive law: [tex]a\left(b+c\right)=ab+ac[/tex]

[tex]\frac{1}{2}km+\frac{1}{2}kn=A[/tex]

Add (-1)/2 × kn to both sides

[tex]\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A[/tex]

simplify

[tex]\frac{1}{2}km=-\frac{1}{2}kn+A[/tex]

Divide both sides by k/2

[tex]\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}[/tex]

[tex]m=\frac{2A-kn}{k}[/tex]

Therefore,

[tex]m=\frac{2A-kn}{k}[/tex]

Hence, option C is true.

Answer:

6 3/5 points

Step-by-step explanation:

Steve is creating a web page.

Step 1

He starts with a font of 5 9/10 points and decreases it by 1/2.

Hence: Current font

= 5 9/10 - 1/2

= 5 + ( 9/10 - 1/2)

Lowest common denominator

= 10

= 5 + (9 - 5/10)

= 5 + 4/10

= 5 + 2/5

= 5 2/5 points

Step 2

He decreases it again by 6/10 points.

Current fonts

= 5 2/5 - 6/10

= 5 + ( 2/5 - 6/10)

Lowest common denominator

= 10

= 5 + (4 - 6/10)

= 5 + (-2/10)

= 5 - 1/5

= 4 4/5 points

Step 3

Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points.

New font

= 4 4/5 points + 1 4/5 points

Lowest common denominator = 5

= 4 + 1 + (4/5 + 4/5)

= 5+ ( 4 + 4/5)

= 5 +(8/5)

= 6 3/5 points

The best estimate of the font's final size is 6 3/5 points

Answer:

8

Step-by-step explanation:

Dominique - 12

Brother- 12 / 6 * 4

12 / 6 is 2 then 2 * 4 is 8.

So her brother is 8 years old.

To prove this multiply 8 by 2 givig you 16. then 16 - 4 giving you 12. This means the answer is correct because dominique is supposed to be 4 years less than TWICE THE AGE OF HER BROTHER.

Answer:

303 cents.

Step-by-step explanation:

Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer

We know that, dollar is equal to 100 cents

2 dollars = 200 cents

It means, Daniel found 9 cents in his backpack, 89 cents in the couch, and 200 cents and 5 cents in the drawer.

Price = 9+89+200+5

= 303 cents

Hence, Daniel found 303 cents.

Answer:

a its not straight and its negative

Answer:

I'm pretty sure it is nonlinear with negative trend.

Step-by-step explanation:

I think this because the data points are going down so, negative. And linear means "to be in a straight line" which it is not. So the answer would be nonlinear with a negative trend.

Answer: Graph B

Step-by-step explanation:

The unit price for the strawberries is:

= 1.5 / 2

= $0.75 per pound

Graph B is the right graph as it uses a unit price of $0.75 per pound for strawberry price. This is why it has points of the graph that mirror the friends purchases such as (2, 1.5) , (3, 2.5) and (4, 3).

Answer:

[tex]x = 18[/tex]

[tex]y = 6\sqrt{3}[/tex]

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of a right triangle is called the hypotenuse and the other two sides are called the legs.  

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides as follows:

Cosine Ratio

[tex]\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

Sine Ratio

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Consider the angle of θ=30°, then we can write:

[tex]\displaystyle \cos 30^\circ=\frac{x}{12\sqrt{3}}[/tex]

Solving for x:

[tex]x=12\sqrt{3}\cos 30^\circ[/tex]

Since:

[tex]\cos 30^\circ=\frac{\sqrt{3}}{2}[/tex]

Then:

[tex]x=12\sqrt{3}\cdot \frac{\sqrt{3}}{2}[/tex]

[tex]x = 18[/tex]

Now apply the sine:

[tex]\displaystyle \sin 30^\circ=\frac{y}{12\sqrt{3}}[/tex]

Solving for y:

[tex]y=12\sqrt{3}\sin 30^\circ[/tex]

Since:

[tex]\sin 30^\circ=\frac{1}{2}[/tex]

Then:

[tex]y=12\sqrt{3}\cdot \frac{1}{2}[/tex]

[tex]y = 6\sqrt{3}[/tex]

Answer:

[tex]x = 18[/tex]

[tex]y = 6\sqrt{3}[/tex]
