represents the length of the first piece, find the lengths of all three pieces

Answer:

The answer is the last answer choice (D).

Step-by-step explanation:

f(x) = [tex]x^{3} +2x^{2}[/tex]

When you factor, you get the values 0 and -2, 0 have a multiplicity of 2 and -2 having a multiplicity of 1.

Answer:

5 times

Step-by-step explanation:

Given that,

The area of Canada is approximately 1×10⁷ square kilometers, and the area of Mexico is approximately 2×10⁶ square kilometers.

We need to find the area of Canada is approximately how many times the area of Mexico.

Dividing both areas as follows :

[tex]\dfrac{A_c}{A_m}=\dfrac{10^7}{2\times 10^6}\\\\\dfrac{A_c}{A_m}=5\\\\A_c=5A_m[/tex]

So, the area of Canada is approximately 5 times the area of Mexico.

Answer:

-they are all straight lines

-they all cross the y-axis at (0,4)

Step-by-step explanation:

Answer:

All these graphs intercept the y-axis at 4 OR

All these graphs b = 4

All these graphs have a slope or are non-vertical

Step-by-step explanation:

y = 3x + 4

y = 2x + 4

y = -x +4

y = -5x + 4

All these graphs intercept the y-axis at 4

slope intercept equation is y = mx + b, the line intercepts the y-axis at b

In addition, all these graphs have a slope or are non-vertical

Sorry for being a little slow. I had to calculate each one :)

Answer:

20 years

Step-by-step explanation:

Given

[tex]H = 3t + 5[/tex]

[tex]0 \leq H \leq 100[/tex]

Required

Solve for t when H = 65ft

[tex]H = 3t + 5[/tex]

Substitute 65 for H

[tex]65 = 3t + 5[/tex]

Make 3t the subject

[tex]3t = 65 - 5[/tex]

[tex]3t = 60[/tex]

Solve for t

[tex]t = 60/3[/tex]

[tex]t = 20[/tex]

This implies that the duration is 20 years

Answer:

6 centimeters and 4 centimeters

Step-by-step explanation:

According to the Triangle Inequality, the sum of the lengths of any two sides of a triangle has to be greater than the third side. The answer choices that satisfy the Triangle Inequality is 6 centimeters and 4 centimeters.

Answer:

8x+70

Step-by-step explanation:

2 x width is (24+3)x2 = 54

2 x length is 2(4x+8)= 8x+16

Length + width = 54+8x+16 ===>

Perimeter = 8x+70

Answer:

wah??

Step-by-step explanation:

The answer is  ( D ),   y ≤ 6

The range begins from minimum value to maximum value.

However, in the graph. There's no minimum value as it's heading toward negative infinity.

So we use y ≤ 6 instead.

So the clear answer is y ≤ 6 or ( D )

Answer:

The system of equations is:

[tex]a+s = 250\\5a+2.50s = 837.50[/tex]

Here a is the number of adult tickets and s is the number of student tickets

Step-by-step explanation:

We will use the given statements to make a system of equations for the given scenario.

First of all we have to decide which variables to be used.

Let a be the number of adult tickets and

Let s be the number of student tickets

So according to the statement that the department sold 250 tickets in total, the equation will be:

[tex]a+s = 250[/tex]

This is equation one of the system of equations

According to the statement that cost of adult ticket is $5, total cost of adult tickets will be: [tex]5a[/tex]

According to the statement that cost of student ticket is $2.50, total cost of student tickets will be:[tex]2.50s[/tex]

The total earning was $837.50 so the second equation will be:

[tex]5a+2.50s = 837.50[/tex]

Hence,

The system of equations is:

[tex]a+s = 250\\5a+2.50s = 837.50[/tex]

Here a is the number of adult tickets and s is the number of student tickets

Answer:

24 movies

Step-by-step explanation:

48 is a constant. 2 and 4 are variables. So we write 48+2x=4x to show they are equal after some amount of movies. Isolate to get 4x-2x=48. Simplify to get 2x=48. Divide each side by 2 to get x=24. The answer is 24.

Hope this helps!

Answer:

x>-5

Step-by-step explanation:

divide by -2, but flip the sign because it's negative

x>-5

Answer:

X>-5

Step-by-step explanation:

[tex] - 2x < 10 \\ [/tex]

Multiply by (-1) to get rid of - next to x, by doing so the "<" changes into ">"

[tex]2x > - 10 \\ x >- 10 \div 2 \\ x > - 5[/tex]

Answer:

the first problem is - 85 and you continue from there

We have the price of a senior ticket is $4 and the price of a child ticket is $7

Step-by-step explanation:

We can form two equations, let the price of a senior ticket be s and the price of a child ticket be c.

We have from day 1:

A: 3s + 9c = 75

And from day 2:

B: 8s + 5c = 67

Now we can rewrite A as:

A: 24s + 72c = 600

And can rewrite B as:

B: 24s + 15c = 201

Now A-B can be written as:

A-B: 57c = 399

So c = 7

Now substituting this back into A we get:

A: 3s + 63 = 75

A: 3s = 12

So s = 4

We have the price of a senior ticket is $4 and the price of a child ticket is $7
