the freshman class are Economics majors, how many students are in the freshman
class?

Answer:

y = -50x + 400

Step-by-step explanation:

Took the test. Hope this helps.

a) Expression is [tex]y+35[/tex]

b) Number of marbles with Nicola [tex]=[/tex] Total number of marbles [tex]-35[/tex]

An algebraic expression is one that is composed of integer constants, variables, and algebraic operations.

Number of marbles with Nicola [tex]=y[/tex]

Number of marbles with Sean [tex]=25[/tex]

Number of marbles with Vicky [tex]=10[/tex]

So,

Total number of marbles [tex]=y+25+10[/tex]

                                         [tex]=\boldsymbol{y+35}[/tex]

Number of marbles with Nicola [tex]=[/tex] Total number of marbles [tex]-25-10[/tex]

                                                    [tex]=[/tex] Total number of marbles  [tex]\boldsymbol{-35}[/tex]

Answer:

-4

Step-by-step explanation:

Slope (m) =  

ΔY

ΔX

=  

-4

1

= -4

θ =  

arctan( ΔY ) + 360°

ΔX

= 284.03624346793°

ΔX = 5 – 2 = 3

ΔY = -8 – 4 = -12

Distance (d) = √ΔX2 + ΔY2 = √153 = 12.369316876853

Answer:

y = -3x -2 ( this is only for 5 )  

Step-by-step explanation:

Step 1:

First, we need to understand that lines that are perpendicular have slopes that are opposites and reciprocals of each other.

Step 2:

So our initial equation is 2x-6y= 10. We want to rearrange this so that it is in slope-intercept form: y= 1/3x -(10/6). In this form, we can derive the slope of our new line. Because the slope is 1/3, our new slope is -3 ( based on step 1 ).

Step 3:

Now that we have the slope of our new line, we can use the point-slope formula to get our specific line that passes through ( 2, -8 ).

y - y1 = m( x - x1 )

y- ( -8 ) = -3( x - 2 )jhvjjfjhjfhcgch

y + 8 = -3x + 6

y = -3x -2 !

Answer:

f^-1 (x)= x/18 - 7/54

Step-by-step explanation:

The inverse function of h(x) is x/18 - 7/54

The inverse function is defined as a function obtained by reversing the given function.

Given function h(x) = 18x+7/3

Let g(x) function is the inverse function of h(x)

Suppose y = h(x)

y = 18x+7/3  

y-7/3 = 18x

y/18 - 7/54 = x

g(x) = x/18 - 7/54

Hence g(x) = x/18 - 7/54 is the inverse function of h(x)

Answer:

x=16

Step-by-step explanation:

3 times 16 equals 48 minus 9 equals 39

Answer:

16

Step-by-step explanation:

To solve the equation you must isolate the variable.

3x-9=39

So first, add 9 to both sides

3x-9+9=39+9

3x=48

Then divide both sides by 3

3x/3=48/3

The two triangles are congruent by SAS criteria

Answer:because 2 can’t go into 9 and 8 can’t go into 3

Step-by-step explanation

-

The ratio shows how many times one value is contained in another value.

3/2 ≠ 9/8

The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

3:2 and 9:8

We will simplify it in its simplest form.

3:2 = 3/2

This is the simplest form.

9:8 = 9/8

This is in its simplest form.

So,

3/2 is not equal with 9/8

If the two ratios are the same we can call them equivalent ratios.

Thus,

3/2 ≠ 9/8

The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios.
