so 600 x .20= 120

Answer:

Option a. No; the domain values are at regular intervals and the range values have a common sum 1.

Step-by-step explanation:

x1=3, x2=1, x3=-1, x4=-3

y1=1, y2=2, y3=3, y4=4

x1-x2=3-1→x1-x2=2

y2-y1=2-1→y2-y1=1

x2-x3=1-(-1)=1+1→x2-x3=2

y3-y2=3-2→y3-y2=1

x3-x4=-1-(-3)=-1+3→x3-x4=2

y4-y3=4-3→y4-y3=1

The data doesn't show an exponential function, because the domain values are at regular intervals and the range values have a common sum 1.

Melanie drove a total of 500 miles over three days. To determine how many miles she drove each day, we divided total miles by total days. This gives us 166.67 miles or 166 2/3 miles as a mixed number.

The subject of the provided question is related to simple division. Here, Melanie has traveled 500 miles in total over the course of three days, and she drove the same distance each day. Mathematically speaking, to find out how many miles Melanie drove each day, we need to divide the total distance by the number of days. Hence, we divide 500 miles by 3 days.

This comes out to be 166.67 miles, which is the decimal format of the distance traveled by Melanie each day. However, the question asks for the answer to be written as a mixed number. Therefore, 166.67 miles can be expressed as 166 2/3 miles per day, as a mixed number. This is calculated by expressing the decimal .67 as a fraction.

Answer:

The triangles are similar, because the angles are congruent and the sides are proportional.

Step-by-step explanation:

The first step to see if the triangles are similar is to see if the angles are the same.

The third angle in the large triangle is

30 + 65+ unknown = 180

95 + unknown = 180

Subtract 95 from each side

unknown = 180-95

unknown = 85

So the angles are the same.

Lets check the ratio of the the sides

14            10

------ = ----------

7                5    

Both simplify to 2/1  so the ratio's are the same.

The triangles are similar because the angles are congruent and the sides are proportional.

Hence, the option (A) is the correct answer i.e., The graph of [tex]g(x + 1)[/tex]is the graph of [tex]g(x)[/tex] shifted right one unit.

Final answer:

The true statement for the graphs of all functions g(x) is that the graph of g(x + 1) is the graph of g(x) shifted left by 1 unit.

Explanation:

When considering the transformation of the graph of a function g(x) to g(x + 1), we are applying a horizontal shift to the graph. According to the principles of graph transformation, when we add a positive constant to the input of a function, every point on the graph shifts left by that amount. Therefore, the graph of g(x + 1) is the same as the graph of g(x), shifted to the left by 1 unit. This corresponds to the option C, which states that adding 1 to the input of the function shifts the graph to the left by 1 unit.

Answer:

1) [tex]2s+s\leq18[/tex]

2) 6 years old

Step-by-step explanation:

Let Hannah's age be [tex]h[/tex] and her sister's age be [tex]s[/tex]

It means [tex]h=2s[/tex]

It means the sum is LESS THAN or EQUAL TO 18. So we can write:

[tex]h+s\leq18[/tex]

1. We can substitute first equation into second equation to get our desired inequality of the situation. Thus,

[tex]h+s\leq18\\2s+s\leq18[/tex]

2. To find MAXIMUM age of Hannah's sister, let's further simplify the inequality from number 1. So,

[tex]2s+s\leq18\\3s\leq18\\s\leq\frac{18}{3}\\s\leq6[/tex]

Hence, Hannah's sister's age is LESS THAN OR EQUAL TO 6. So maximum age of her sister is 6.

the bacteria's population is 120

Step-by-step explanation:

Answer:

After 40 hrs it is 213.333 bacterias

Approximately 213 bacterias

Step-by-step explanation:

Initial population of bacteria is 40

And it doubles every 15 hrs

If 15 hrs is double

1 hrs is 0.13333

Then 10 hrs is 1.3333

So the first 15 hrs

It multiplies to 40*2= 80

The second 15 hrs it multiplies by 80*2=160

The next 10 hrs it multiplies by

A.  F(x) = x^3+9x^2+27x+27

Step-by-step explanation:

I am not 100% sure but I think this is right.

I found the root for this equation: x=-3

Hope this helps!

Answer:

The correct option is D.

Step-by-step explanation:

In option A,

The given function is

[tex]F(x)=x^3+9x^2+27x+27[/tex]

[tex]F(x)=x^3+3(3)x^2+3(3^2)x+3^3[/tex]

[tex]F(x)=(x+3)^3[/tex]              [tex][\because (a+b)^3=a^3+3a^2b+3ab^2+b^3][/tex]

Equate the function equal to zero, to find the roots.

[tex](x+3)(x-3)(x-3)=0\Rigtharrow x=-3[/tex]

The real root of this function is -3 with multiplicity 3. It means this function has 3 real roots.

In option B,

The given function is

[tex]F(x)=x^3+3x^2-9x-27[/tex]

[tex]F(x)=x^2(x+3)-9(x-3)[/tex]

[tex]F(x)=(x^2-9)(x+3)[/tex]

[tex]F(x)=(x+3)(x-3)(x+3)[/tex]         [tex][\because a^2-b^2=(a+b)(a-b)][/tex]

Equate the function equal to zero, to find the roots.

[tex](x+3)(x-3)(x+3)=0\Rigtharrow x=-3,3,-3[/tex]

Therefore, this function has 3 real roots.

In option C,

The given function is

[tex]F(x)=x^3-9x^2+27x-27[/tex]

[tex]F(x)=x^3-3(3)x^2+3(3^2)x-3^3[/tex]

[tex]F(x)=(x-3)^3[/tex]              [tex][\because (a-b)^3=a^3-3a^2b+3ab^2-b^3][/tex]

Equate the function equal to zero, to find the roots.

[tex](x-3)(x-3)(x-3)=0\Rigtharrow x=3[/tex]

The real root of this function is 3 with multiplicity 3. It means this function has 3 real roots.

In option D,

[tex]F(x)=x^3+3x^2+9x+27[/tex]

[tex]F(x)=x^2(x+3)+9(x+3)[/tex]

[tex]F(x)=(x+3)(x^2+9)[/tex]

Equate the function equal to zero, to find the roots.

[tex](x+3)(x^2+9)=0[/tex]

[tex]x+3=0\Rightarrow x=-3[/tex]

[tex]x^2+9=0\Rightarrow x^2=-9\Rightarrow x=\pm 3i(Imaginary)[/tex]

The roots of this functions are -3, 3i and -3i. Since this function has exactly one real root, therefore option D is correct.

Answer:

Number of​ restaurant-purchased meals eaten in a​ restaurant = 70

Number of​ restaurant-purchased meals eaten in a​ car = 22

Number of​ restaurant-purchased meals eaten in a​ home = 60

Step-by-step explanation:

Let the number of people that will eat in a restaurant be R.

Let the number of people that will eat in a car be C.

Let the number of people that will eat in a home be H.

From the information given in the problem we have,

R+C+H = 152 ____equation (1)

C+H-R = 12 ____equation (2)

R = H+10 ____equation (3)

1) Plugging in R=H+10 from equation 3 into the equation 2, we get

C+H-R=12

=> C+H-(H+10)=12

=> C+H-H-10=12

2) Cancelling out +H and -H, we get

C-10=12

3) Add 10 to both sides

C-10+10=12+10

4) Cancelling out -10 and +10, we get

C=22

5) Plugin C=22 in equation 1, we have

R+C+H = 152

=> R+22+H=152

Subtract 22 from both sides,

R+22+H-22=152-22

Cancelling out +22 and -22 from the left side, we get

R+H=130 ____let it be equation (4)

6) Plugin C=22 in equation 2, we have

C+H-R = 12

22+H-R = 12

Subtracting 22 from both the sides, we get

22+H-R-22 = 12-22

Cancelling out +22 and -22 from the left side,

H-R = -10 ____let it be equation (5)

7) Adding equation 4 and equation 5, we get

(R+H)+(H-R) = 130 + (-10)

=> R+H+H-R = 130-10

8) Cancelling out R and -R from the left side, we get

2H = 120

9) Dividing both sides by 2, we get

[tex]\frac{2H}{2} = \frac{120}{2}[/tex]

10) Cancelling out the 2's from the left side, we have

H=60

11) Plugging in C=22 and H=60 in the equation 1, we have

R+C+H = 152

=> R+22+60=152

=> R + 82 = 152

12) Subtracting 82 from both the sides, we get

R + 82 -82 = 152 -82

13) Cancelling out +82 and -82 from the left side, we get

R = 70

So, C=22, H=60, R=70

Answer: (A) 10

Step-by-step explanation:

                Value       Quantity     =  TOTAL Value

dimes:        .10            Q + 5        =    .10(Q = 5)

quarters:    .25               Q           =      .25Q

Dimes + Quarters = $4.00

.10(Q + 5) + .25Q = 4.00

.10Q + .50 + .25Q = 4.00

           .50 + .35Q = 4.00

                    .35Q = 3.50

                          Q = 10

Quarters = 10

Dimes = Q + 5

           = 10 + 5

           = 15

Answer: Option A, she has 10 quarters.

Step-by-step explanation:

We have quarters of $0.25 and dimes of $0.10

We have 5 more dimes than quarters and a total of $4.00

How many quarters Ms. Kincaid has?

Q is the number of quarters and D the number of dimes.

We have the system of equations:

D = Q + 5

Q*$0.25 + D*$0.10 = $4.00

First, we can replace the first equation into the second and solve it for Q.

Q*$0.25 + (5 + Q)*$0.10 = $4.00

Q*($0.25 + $0.10) + $0.50 = Q*($0.35) + $0.50  = $4.00

Q = (4.00 - 0.50)/0.35 = 3.50/0.35 = 10

So she has 10 quarters.

The correct option is A.

Answer:

(x, y) = (- 3, - 2)

Step-by-step explanation:

given the 2 equations

5x + 7y = - 29 → (1)

y = x + 1 → (2)

substitute y = x + 1 into (1)

5x + 7(x + 1) = - 29 ( distribute and simplify left side )

5x + 7x + 7 = - 29

12x + 7 = - 29 ( subtract 7 from both sides )

12x = - 36 ( divide both sides by 12 )

x = - 3

substitute x = - 3 into (2)

y = - 3 + 1 = - 2

solution is (- 3, - 2 )
