Answer:

y = -1/3 x - 7

Step-by-step explanation:

First, the intercept form is in y = ax + b, where b is the intercept at y-axis which is -7, then pick any point in the line, in the case I chose (3,-8), then substitute it into the equation, -8 = 3a - 7, then solve for a, get 3a = -1, so a = -1/3 which is the slope.

The value of the f(3) is -8 or f(3)=-8 if the equation of the function f(x) = -8(3)⁰ or f(x) = -8 option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

For the function, f(x) = -8

f(x) = -8

For all values of x:

The above function can be written as follows:

f(x) = -8x⁰

PLug x = 3 in the function:

f(x) = -8(3)⁰

f(x) = -8

Thus, the value of the f(3) is -8 or f(3)=-8 if the equation of the function f(x) = -8(3)⁰ or f(x) = -8 option (C) is correct.

Step-by-step explanation:

if 9 boxes is 42.75 then 1 box is 4.75 dollars

so 13 boxes would be 13X3.75 which is 61.75$

if 9b=$42.75

1b=x

9bx=$42.75b

x=$42.75b÷9b

x=$4.75

Answer:

x=4

y=2

Step-by-step explanation:

2x+2y=12

x−y=2

​In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

2x+2y=12,x−y=2

To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.

2x+2y=12,2x+2(−1)y=2×2

Simplify.

2x+2y=12,2x−2y=4

Subtract 2x−2y=4 from 2x+2y=12 by subtracting like terms on each side of the equal sign.

2x−2x+2y+2y=12−4

Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.

2y+2y=12−4

Add 2y to 2y.

4y=12−4

Add 12 to −4.

4y=8

Divide both sides by 4.

y=2

Substitute 2 for y in x−y=2. Because the resulting equation contains only one variable, you can solve for x directly.

x−2=2

Add 2 to both sides of the equation.

x=4

The system is now solved.

x=4,y=2

Correct choice is B) x=4.

answer is 4

because y=2 then you subsistute it in and then you find X

x-y=2 turns to x=y+2 then you subsistute that into x of the equation 2x+2y=12 which then is 2(y+2)+2y =12 and you should get y=2 then you grab the other equation x-2=2 and you should get x=4

Answer:

Step-by-step explanation:

[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}[/tex]

Remember that exponents (or powers) of the same basis can be divided by subtracting the exponents. For example [tex]\frac{x^n}{x^m} =x^{n-m}[/tex]

Using this information, we can easily rearrange our equation to look like this:

[tex]\frac{x^2}{x^5} \frac{y^{-3}}{y^2}[/tex]

Now that the basis are the same, we can conveniently subtract the exponents to get the following result:

[tex]x^{-3}y^{-5}[/tex] or [tex]\frac{1}{x^3y^5}[/tex]. And that's the final answer.

Answer:

y=x+5

Step-by-step explanation:

it is not a proportional relationship and it starts at 5 and the slope is 1 so just x

Answer:

your answer is C

Step-by-step explanation:

I solved this quick enough bc the y Intercept is 5 and the only answer that has that is C. you can also solve this by graphing every equation shown until you find which equation has a similar graph. also don't feel sorry. this is a place for us all to learn :)

Answer:

10a+5b-30

Step-by-step explanation:

Apply the distributive law = ma + mb +  mc

5 (2a+b-6) = 5 2a + 5b + 5 (-6)

Then Simplify: 5 2a + 5b + 5 (-6)

= 10a+5b-30

Hope this helps :D

Answer:

y-intercept is 30

Step-by-step explanation:

Answer:

The slope is -3.75 or -15/4.

Step-by-step explanation:

The formula for slope is the change in y over the change in x.

To do this, you subtract 7-3 to get you 4 on the bottom of the fraction and -7-8 which is -15.

So pretty much, you get -15/4. :)

Answer:

41.4feet

Step-by-step explanation:

Using the SOH CAH TOA identity

Given the following

Distance of Rafael from the tower = 55feet = Adjacent

Angle of elevation = 37degrees

Required

Height of the tower = Opposite

Since Tan theta = opp/adj

Tan 37 = x/55

x = 55tan37

x = 55(0.7536)

x = 41.4

Hence the tower is 41.4feet up the viewing platform

Answer:

[tex]\angle EHG = 80[/tex]

Step-by-step explanation:

Given

ABC ∼ EHG

See attachment

Required

Determine [tex]\angle EHG[/tex]

First, we calculate x in ABC

[tex]x + 2x + 60= 180[/tex]

[tex]3x + 60= 180[/tex]

[tex]3x = 120[/tex]

[tex]x = 40[/tex]

The corresponding angle to [tex]\angle EHG[/tex] is [tex]\angle ABC[/tex]

and

[tex]\angle ABC = 2x[/tex]

[tex]\angle ABC = 2 * 40[/tex]

[tex]\angle ABC = 80[/tex]

Hence:

[tex]\angle EHG = 80[/tex]
