Answer:

d represents distance

d = -16.8

Step-by-step explanation:

From the question, we are to find the vale of d from the expression

12+d = -4.8

Subtract 12 from both sides

12+d-12 = -4.8-12

d = -4.8-12

d = -16.8

Hence the value of d that makes two equation true is 16.8

d represents distance

d represents distance

d = -16.8

12+d = -4.8

12+d-12 = -4.8-12

d = -4.8-12

d = -16.8

Answer:

The equation that models the population growth is y = 90,000(1.02)^x

Step-by-step explanation:

The formula of the exponential growth is y = a [tex](b)^{x}[/tex], where

Let us solve the question

∵ At x = 0, the population y = 90,000

→ That means the initial value is 90,000

∴ a = 90,000

→ Substitute it in the form of the equation above

∴ y = 90,000 [tex](b)^{x}[/tex]

→ To find b use any values from the table to substitute x and y

∵ At x = 1, y = 91,800

∵ 91,800 = 90,000 [tex](b)^{1}[/tex]

∴ 91,800 = 90,000 b

→ Divide both sides by 90,000

∵ [tex]\frac{91,800}{90,000}[/tex] = [tex]\frac{90,000b}{90,000}[/tex]

∴ 1.02 = b

→ Substitute it in the equation above

∵ y = 90,000 [tex](1.02)^{x}[/tex]

∴ The equation that models the population growth is y = 90,000(1.02)^x

3.66666666667

Step-by-step explanation:

First, we need to find the unit rate to figure out how many miles Shane rides in 1 hour. To do this it is simple, I divided 12 and 2 to get 6 miles per hour. Then we would do 22/6 but we get a decimal so it would be about 3.66666666667.

[tex]\Delta ABE\cong \Delta MNP[/tex]

To find:

The congruent angles and sides, then find the another valid congruency statement.

Solution:

We have,

[tex]\Delta ABE\cong \Delta MNP[/tex]

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

Using CPCTC, we get

Angles:

[tex]\angle A\cong \angle M[/tex]

[tex]\angle B\cong \angle N[/tex]

[tex]\angle E\cong \angle P[/tex]

Sides:

[tex]AB\cong MN[/tex]

The another congruent statement is [tex]\Delta BEA\cong \Delta NPM[/tex].

Therefore, the required table is

6(8+3x)

Step-by-step explanation:

48+18x = 6(8+3x)

Step-by-step explanation:

So we're trying to get from minutes to weeks.  The time intervals in question are:

Minutes -> Hours -> Days -> Weeks

So we set up our dimensional analysis.  We're solving for amount of problems, so that goes in the numerator of the first fraction:

[tex]\frac{1problem}{1.5min}[/tex]

Now we want to know how many minutes in an hour, so we multiply by the next fraction:

[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr}[/tex]

After that, we want to know how many hours in a day:

[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr} * \frac{24hr}{1d}[/tex]

and how many days in one week:

[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr} * \frac{24hr}{1d} * \frac{7d}{1w}[/tex]

To solve the dimensional analysis problem, we multiply across the top of the entire expression, then divide across the bottom.  So:

1 * 60 * 24 * 7 = 10,080

And then divide that by the bottom:

10,080 / 1.5 / 1 / 1 / 1 = 6,720

So you can solve 6,720 problems in one week.  Multiply that by six and we get your answer:

40,320 dimensional analysis problems can be completed in 6 weeks of Chemistry class.

(6x - 7) (6x - 7)

Step-by-step explanation:

A perfect square trinomial will be in the form of [tex]a^2[/tex] ± [tex]2ab + b^2.[/tex] A trick to factoring a perfect square trinomial would to write it as [tex](a^2[/tex]±[tex]b^2)[/tex]. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).

[tex]36x^2 -84x + 49[/tex] is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes [tex]36x^2[/tex], 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms ( [tex](2) (7) (6x)[/tex] is [tex]84x[/tex]).

So, we can use the trick described earlier, and the answer would be [tex](6x-7)^2[/tex], also known as (6x-7) (6x-7).

depends how much money is deposited, however, the choices can be just D or E

Answer:

B,D,E

Step-by-step explanation:

Does it say how much was deposited? Ok so deposit means your bank gets bigger so it cannot be less than -28.

My guess is that it will be either B,D,E

The reason I say my guess is because I think the question should have given you an amount of how much was deposited.

Answer:

y = -1/4x+2

Step-by-step explanation:

The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.
