Answer:

y = [-½]x + [-5]

Step-by-step explanation:

Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.

m = slope = ∆y/∆x

Using two pairs of values from the table, (-2, -4) and (0, -5),

Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2

m = -½

b = y-intercept = the value of y when x is 0 = -5

b = -5

✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b

Thus:

y = [-½]x + [-5]

Answer:

-6

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

It is asking for the base. The base is -6. The exponent is 2. The exponential form would be -6^2.

I have added an attachment so you can understand better.

They are substituing the exponent b= 5 and the base a= 2

it would be 2x2x2x2x2

Answer:

[tex]x = \frac{32}{45}[/tex]

Step-by-step explanation:

Given

[tex]1 * (2\frac{2}{3}) = \frac{1}{2}x + 3\frac{1}{4}x[/tex]

Required

Solve for x

Express all fractions as improper

[tex]1 * \frac{8}{3} = \frac{1}{2}x + \frac{13}{4}x[/tex]

Take LCM

[tex]1 * \frac{8}{3} = \frac{2 + 13}{4}x[/tex]

[tex]\frac{8}{3} = \frac{15}{4}x[/tex]

Cross Multiply

[tex]15x * 3 = 4 * 8[/tex]

[tex]45x = 32[/tex]

Make x the subject

[tex]x = \frac{32}{45}[/tex]

Answer:

c. (4,3)

Step-by-step explanation:

If you look at all the rest of the coordinates, compared to (4,3). None of them are in the red area. They are either in the blue, or the orange. To be a solution it has to be in both areas, (the red). Hope this helps!

Answer:

-1

Step-by-step explanation:

Any number less than -2 (ex -3, -4, -5) are less than -2

Answer:

-1

Step-by-step explanation:

If you look at a number line, you will see that -1 comes before -2. Since -2 is a negative number, then the lower the number, the greater it is.

Answer:

20.75 Absolute change

Step-by-step explanation:

Answer:

For the first group we have the pairs:

year           population

0                20

1                 80

2                320

3                 1,280

4                 5,120

5                 20,480

Here we can see that the population quadruples each year

(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)

then the population equation is:

P(0) = 20

P(1) = 20*4

P(2) = (20*4)*4 = 20*4^2

We already can see the pattern, then we can write this relationship as:

P(t) = A*(4)^(t)

Where:

t represents time in years, and A is the initial population, that we know it is 20, then:

P(t) = 20*(4)^t

This is the function that represents the table.

B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:

Q(t) = 20*(3)^t

C) Now, if the initial population of the second group is 40, the equation becomes:

Q(t) = 40*(3)^t

The population by year 3 is given by replacing t by 3, then:

Q(3) = 40*(3)^3 = 1080

And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:

1,280 - 1,080 = 200

So the first group is larger by 200 squirrels.
