Which equation could have been used to create this graph?

Answer:

2+2929?

Step-by-step explanation:

answer= 2 + 29 = 31, then multiply it by 1= then, you still have it, then add another 29, then theres ur answer

Explanation:

The term "disjoint" is another way of saying "mutually exclusive". If two sets are disjoint, then they have nothing in common. Put another way, if two sets are disjoint, then it's not possible to be part of both sets at the same time.

In this case, it is not possible to be both an aunt and an uncle simultaneously for any one person. So this is why choice B is the answer.

Answer:

D) -1

Step-by-step explanation:

got it right on edge :)

Vector addition is done by addition of the components

The value of a is -1

a = –1

Reason:

The given parameters are;

q = <-4, 1>

r = <a, 3>

7·(q + r) = <-35, 28>

Required:

The value of a

Solution;

By vector addition of the components of q, and r, we have;

q + r =  <(-4 + a),    4>

By plugging in the value of q + r from the above step, we have;

7·(q + r)  = <-35, 28> Given

Therefore, by comparison of components, we have;

7 ×(-4 + a) = -35

a = -5 + 4 = -1

a = –1

The correct option for the value of a is –1

Given:

The graph of a function f(x).

To find:

The solution set for f(x)>0 and f(x)≤0.

Solution:

From the given graph it is clear that, the function intersect the x-axis at 3 points, i.e., x=-4, -3 and -2.

The graph is above the x-axis before -4 and between -3 and -2.

So, the solution set for f(x)>0 is [tex](-\infty,-4)\cup (-3,-2)[/tex].

The graph is below the x-axis between -4 and -3; and after -2. For f(x)≤0, those values are in the solution set for which f(x)=0, i.e., x-intercepts. So, we use close brackets in the interval notation.

So, solution set for f(x)≤0 is [tex][-4,-3]\cup [-2,\infty)[/tex].

Answer:thx so much I needed them

Step-by-step explanation:

Answer:

A variable that depends on one or more other variables. For equations such as y = 3x – 2, the dependent variable is y. The value of y depends on the value chosen for x. Usually the dependent variable is isolated on one side of an equation.

$10 = 4x

Step-by-step explanation:

The "x" would represent how much the apples would cost. So next you would divide both sides by 4x and then it would leave you with 2/5.

Answer:

72 blue quilt squares

Step-by-step explanation:

Total number of quilt squares = 160

Percentage of no. of red quilt squares = 25%

Percentage of no. of yellow quilt squares = 30%

So, percentage of no. of blue quilt squares = 100 - (25 + 30) = 45%

No. of blue quilt squares = [tex]\frac{45}{100} *160=\frac{45*160}{100} = \frac{7200}{100} =72[/tex]

Answer:

50 pockets

Step-by-step explanation:

Given

[tex]Total = 75\ yd[/tex]

[tex]Pocket = 1\frac{1}{2}yd[/tex]

Required

Determine the number of pockets

To calculate the required , we make use of:

[tex]Pockets = \frac{75yd}{1\frac{1}{2}yd}}[/tex]

[tex]Pockets = \frac{75}{1\frac{1}{2}}}[/tex]

Convert the denominator to decimal

[tex]Pockets = \frac{75}{1.5}[/tex]

[tex]Pockets = 50[/tex]

Hence, she can lace 50 minutes

Alternative hypothesis:

[tex]\mathbf{H_a = \sigma_1^2 \ne \sigma_2^2}[/tex]

Step-by-step explanation:

Given that:

Sample 1:

Sample size [tex]n_1[/tex] = 10

Sample mean  [tex]\overline x_1[/tex] = 79.3

Standard deviation [tex]\sigma_1[/tex] = 22.4

Sample 2:

Sample size [tex]n_2[/tex] = 10

Sample mean  [tex]\overline x_2[/tex] = 82.1

Standard deviation [tex]\sigma_2[/tex] = 12.0

To find the alternative hypothesis.

The null and alternative hypothesis can be computed as follows:

Null hypothesis:

[tex]\mathbf{H_o = \sigma_1^2 = \sigma_2^2}[/tex]

Alternative hypothesis:

[tex]\mathbf{H_a = \sigma_1^2 \ne \sigma_2^2}[/tex]

Since, alternative hypothesis is ≠, it shows that it is a two tailed test.

Answer:

5.44 gallons of paint

Step-by-step explanation:

First, we calculate the total area of the walls we need to paint. To do this, we use the formula for the area of a rectangle and we multiply our answer by 4, since there are 4 walls.

Area=(length*width)4

Area=(12*8.5)4

Area=(102ft^2)4

Area=408ft^2

Therefore, the total area of the walls is 408ft^2.

Now, we need to calculate the number of gallons we need to paint 408ft^2 worth of wall. Because we know that one gallon of paint covers 75ft^2, we can calculate this by dividing 408 by 75.

408/75

=5.44 gallons

Therefore, we would need 5.44 gallons of paint to paint the four walls.

I hope this helps!

Answer:

120 such cubes could fit in the prism.

Step-by-step explanation:

Volume of prism = length × breadth × height

[tex] = \frac{5}{3} \times \frac{4}{3 } \times 2[/tex]

[tex] = \frac{40}{9} cm {}^{3} [/tex]

___________________________________

Volume of cube = a³

[tex] = ( \frac{1} {3}) {}^{3} [/tex]

[tex] = \frac{ {1}^{3} }{ {3}^{3} } [/tex]

[tex] = \frac{1}{27} cm {}^{ 3} [/tex]

Answer:

X²(4+x)

Step-by-step explanation:

You pick out the common term

Greetings.

The answer is x²(4+x)

Explanation:

[tex]4x^2+x^3\\[/tex]

By using a common factor, we factor x-term out. We factor the x-term with least degree and that is 2-degree. So we factor x² out.

When factored out, It's similar to dividing. When x² is divided by itself, the result is 1. When x³ is divided by x², the result is x (From the property of exponent.)

Similar to dividing, but we pull x² out.

[tex]4x^2+x^3\\x^2(4+x)[/tex]

Therefore, the answer/factored form is x²(4+x)
