Answer:

[tex]2\frac{2}{3}[/tex]

Step-by-step explanation:

Given the following question:

[tex]-2\frac{1}{3} -(-5)[/tex]

To find the answer to this question we will use KCF (Keep, Change, Change) because we are subtracting from a negative. Then we find the common denominator and subtract the numerators.

[tex]-2\frac{1}{3} -(-5)[/tex]
[tex]-5=\frac{-5}{1}[/tex]
[tex]-2\frac{1}{3} =3\times-2=-6+-1=-7=\frac{-7}{3}[/tex]
[tex]\frac{-7}{3} -\frac{-5}{1}[/tex]
[tex]\frac{-7}{3} \times1=\frac{-7}{3}[/tex]
[tex]\frac{-5}{1} \times3=\frac{-15}{3}[/tex]
[tex]\frac{-7}{3} -\frac{-15}{3}[/tex]
[tex]-7+15=\frac{8}{3} =8\div3=2\frac{2}{3}[/tex]
[tex]2\frac{2}{3}[/tex]

Answer:

D. Yes, because it passes the vertical line test

Step-by-step explanation:

the vertical line test is a test you do by drawing a vertical line through the graph of the function if more than one point from the function lies on the line it does not represent a function

in this graph at any part if you draw a vertical line it passes through one point only

Answer:

Okay so what you need to know here is for a graph to be considered a function it has to pass the vertical line test. This means that if a vertical line is moved across the graph and touches the graph at only one point, then it is considered a function. But if the vertical line touches the graph at more than one point, then it is not considered a function.

Step-by-step explanation:

But for this graph, I know it wouldn't be A, B, or C...... This is because this  and it touches the graph at only one point. We know the graph has to pass the vertical line test to be a function. But we can see here that it does because on the graph it only touches one point as you can see in that attachment. So, It would be D.... I'm pretty sure it is D though. Sorry if it's wrong. I tried to do what I could bcs I'm not really good at math lol

Please mark as brainliest pls and I have attached of graphs that pass the vertical line test to help you understand it better!

Answer:

[tex]5c^2+2cd-2d^2-15[/tex]

Step-by-step explanation:

Perimeter of a 2D shape = distance around the outside.

Therefore, to calculate the perimeter, sum the lengths of all the sides.

[tex]\textsf{perimeter} \ =(4c^2+4cd+12)+(c^2-d^2+1)+(3cd+4d^2-30)+(-5d^2-5cd+2)[/tex]

[tex]=4c^2+4cd+12+c^2-d^2+1+3cd+4d^2-30-5d^2-5cd+2[/tex]

[tex]=4c^2+c^2+4cd+3cd-5cd+4d^2-d^2-5d^2+12+1-30+2[/tex]

[tex]=5c^2+2cd-2d^2-15[/tex]

Answer:

(a) AA Similarity using alternate interior angles

(b) 6.3

Step-by-step explanation:

(a)

Triangles ABD and BDC have a given pair of congruent angles, angles ABD and BCD.

With parallel lines AB and DC and transversal BD, then alternate interior angles ABD and BDC are congruent.

Now we have two pairs of congruent corresponding angles, so by AA Similarity, triangles ABD and BDC are similar.

(b)

Triangles ABD and BDC are similar.

The ratios of the lengths of corresponding sides are equal.

AB/BD = AD/BC

4/6 = 4.2/BC

4BC = 6 × 4.2

BC = 6.3

To compare the shapes of the distributions from the experiments, a z-test can be used.

Your information is incomplete as the distributions aren't given. Therefore, an overview will be given. It should be noted that a z-test is a statistical test that's us used to determine if the means of two population are different when their variances are known.

Z-tests simply test the mean of a distribution. To compare the distributions, the error in the mean will be calculated by dividing the dispersion by the square root of the number of data points.

Step-by-step explanation:

well, the price difference is 60000 - 40000 = 20000.

so, we're told that the price increase acres wise is 800 bucks per acre, but we also know it's a total of 20000, so how may times does 800 go into 20000?

20000 ÷ 800 = 25.

so we know that in 20000 bucks there are 25 acres, so how many will there be in 60000 bucks?

[tex]\begin{array}{ccll} \$&acres\\ \cline{1-2} 20000&25\\ 60000&x \end{array}\implies \cfrac{20000}{60000}=\cfrac{25}{x}\implies \cfrac{1}{3}=\cfrac{25}{x}\implies \stackrel{acres}{x=75}[/tex]

The shape of the cross-section is rectangle, 8 inches by 4 inches.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

Now, from the figure we cut the figure from red line.

As the figure is a three dimensional figure called Cuboid.

We know that cuboid is formed by rectangle surfaces.

Then, the shape of the cross-section is Rectangle whose length is 8 inches and width 4 inches.

Answer:

119

Step-by-step explanation:

Angle ABD and angle DBC are supplementary so their sum is equal to 180

therefore to find the measure of ABD we subtract 61 from 180

<ABD = 180 - 61

<ABD = 119

Add up to get the total number of marbles: (8 + 6 + 12 + 10) = 36

Then subtract the number of blue marbles from the total amount of marbles: 36 - 8 = 28.

28 signifies the amount of marbles that are NOT blue.

So the probability is: 28/36 = 0.77 = About 77%

The final answer is 7/9.

An interior angle of a polygon is found by subtracting 2 from the number of sides, multiplying that by 180 And then divide by the number of sides:

40-2 = 38

38 x 180 = 6840

6840/40 = 171

Answer : 171 degrees

[tex]\bold{\huge{\pink{\underline{ Solution }}}}[/tex]

We have given in the question that,

[tex]\bold{\underline{ To \: Find }}[/tex]

[tex]\bold{\underline{ Let's \: Begin }}[/tex]

Let the two numbers be x and y

According to the question,

[tex]\sf{ x + y = 11......eq(1) }[/tex]

[tex]\sf{ x - y = 19......eq(2) }[/tex]

Solving eq( 1 ) we get :-

[tex]\sf{ x + y = 11 }[/tex]

[tex]\sf{ x = 11 - y ......eq(3 ) }[/tex]

Subsituting eq(3 ) in eq(2) :-

[tex]\sf{ x - y = 19 }[/tex]

[tex]\sf{ ( 11 - y) - y = 19 }[/tex]

[tex]\sf{ 11 - y - y = 19 }[/tex]

[tex]\sf{ 11 - 2y = 19 }[/tex]

[tex]\sf{ - 2y = 19 - 11 }[/tex]

[tex]\sf{ - 2y = 8}[/tex]

[tex]\sf{ y = 8/(-2) }[/tex]

[tex]\sf{ y = - 4 }[/tex]

[tex]\sf{\red{Thus ,\: the\: value\: of \: y = -4}}[/tex]

Now, Subsitute the value of y in eq( 3 ) :-

[tex]\sf{ x = 11 - y }[/tex]

[tex]\sf{ x = 11 - (-4 ) }[/tex]

[tex]\sf{ x = 11 + 4 }[/tex]

[tex]\sf{ x = 15 }[/tex]

Hence, The value of x and y are 15 and (-4) .
