Answer:  Option C, neither.

Step-by-step explanation:

Here we have the table:

x: -10    -3    4    11

y:   1      6    30   120

This means that if our function is f(x), then:

f(-10) = 1

f(-3) = 6

f(4) = 30

f(11) = 120

We want to know if this represents a linear equation or an exponential equation or neither.

First, let's try with a linear equation.

We know that a linear equation can be written as:

f(x) = a*x + b

Then let's input the known values and let's see if this equation works.

We can use two of the known points to get:

f(-10) = 1 = a*-10 + b

f(4) = 30 = a*4 + b

With these equations, we can find the value of a and b, once we find these values, we can see if the equation also works for the other two points.

1 = a*-10 + b

30 = a*4 + b

First, we need to isolate one of the variables in one of the equations.

I will isolate b in the first one:

b = 1 + a*10

Now we can replace this in the other one to get:

30 = a*4 + 1 + a*10

30 = 1 + a*14

30 - 1 = a*14

29 = a*14

29/14 = a = 2.07

and using the equation b = 1 + a*10 we can find the value of b:

b = 1 + 2.07*10 = 1 + 20.7 = 21.7

Then the equation we get is:

f(x) = 2.07*x +  21.7

Now we need to see if this works for the other two points:

for x = -3, we need to get: f(-3) = 6

f(-3) = 2.07*-3 + 21.7 = 15.49

We did not get the value we expected, then we already know that the relationship is not linear.

Now let's see if the relationship can be exponential.

An exponential function is written as:

f(x) = A*(r)^x

Let's do the same as above, let's use two of the known points to find the values of A and r

f(-3) = 6 = A*(r)^(-3)

f(4) = 30 = A*(r)^4

Now we have the system of equations:

30 = A*(r)^4

6 = A*(r)^(-3)

If we take the quotient of these two equations, we get:

(30/6) = (A*(r)^4)/( A*(r)^(-3))

5 = (r^4)*r^3 = r^(4 + 3) = r^7

(5)^(1/7) = r = 1.258

And the value of A is given by:

30 = A*(1.258)^4

30/( (1.258)^4 ) = 11.98

Then the exponential equation is something like:

f(x) = 11.98*(1.258)^x

Now let's see if this equation also works for the other two points:

for x = -10, we should get f(-10) = 1

Let's see that:

f(-10) = 11.98*(1.258)^(-10) = 1.2

And for x = 11 we should get f(11) = 120

f(11) =  11.98*(1.258)^(11) = 149.6

So we get values closer to the ones we should get, but not the exact ones, so this is not an exponential relation.

Then the correct option is C, neither.

Answer:

2

Step-by-step explanation:

8*6 = 48 /  6* 4 = 24

So we would get 48/24.

Now we simplify so 48/24 would simplify to 2.

So the answer is 2.

2. x = 9

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180°.

6x + 16 + 90 + 20 = 180

6x + 126 = 180

6x = 54

x = 9

Answer:

x=1.5 y=-1/3

Step-by-step explanation:

2x-3y=4

2x+8=11

Let's subtract 8 from both sides of the second equation:

2x=3

x=1.5

Substituting this into the first equation, we get:

2(1.5)-3y=4

3-3y=4

-3y=1

y=-1/3

Answer:

x=-5

Step-by-step explanation:

Group all constants on the right side of the equation

Subtract 3 from both sides:

x/5+3-3=2-3

Simplify the arithmetic:

x/5=2-3

Simplify the arithmetic:

x/5=-1

Isolate the x

Multiply to both sides by 5:

x/5 ·5= -1 · 5

Group like terms:

1/5 · 5x = -1 · 5

Simplify the fraction:

x = -1 · 5

Simplify the arithmetic:

x = -5

Answer: 12 possible choices

Step-by-step explanation: there are 4 drink options, and 3 snack options so using the counting principle we would do 4 x 3 to get 12. You could also check individually since it is not a big number by doing: 1 choice with coke and peanuts, another with coke and fruit, etc.

Answer:

a. locate the rise over run between points

b. y2-y1/x2-x1

c. m=slope in y=mx+b

Step-by-step explanation:

a) Use rise over run,

() count how far apart up/down the y's are, and how far apart left/right the x's are

() down in the y's mean it is negative

b) change in y over change in x

() y2 - y1 / x2 - x1

c) find the "m" when it is in slope-intercept form

() y = mx + b

Explanation:

The x coordinates are the same, so we subtract the y coordinates

7-1 = 6

This shows the points have a distance of 6 units. You can plot the two points and count the numbers of spaces between them to confirm this.

Okay so it's basically saying that 30 is greater than 3x by 89

We would represent that mathematically by:

30 - 89 = 3x

So then we just solve this like we usually would

30 - 89 = -59

-59 [tex]\div[/tex] 3 = 19.666. . .

Answer:

25 mini loaves

Step-by-step explanation:

Using the first set you can divide and tell that 1 cup of flour is equal to 2.5 mini loaves, applying that to the other set you can inquire that it's true. So therefore what you need to do is multiply 2.5 times the amount of flour you are using.

10 cups = 25 mini loaves

Answer:  Forest B has 71 more trees than forest A after 100 years.

Step-by-step explanation:

I'm assuming that both functions should read as follows:  (the time, t, is shown as a power, instead as a multiplication).

A(t)=115(1.025)^t

B(t)=82(1.029)^t

Although A starts out with more trees (115), B is growing at 2.9% per year [1.029], versus 2.5% [1.025]for A.

A(100)=115(1.025)^(100)

A(100) = 1359

B(100) = 82(1.029)^(100)

B(100) = 1430

Forest B has 71 more trees than forest A after 100 years.

Answer:

do you remeber the slope formula

y2 - y1 / x2 - x1

so pick two points from those 4 points ill pick -2,15 and 0,3

so 3 - 15 / 0 - 2 gives us -12/-2 or a slope of 6/1 or just 6
