Step-by-step explanation:

- Rewrite equations:

y=3x−11;−3x+y=−13

Step: Solvey=3x−11 for y:

y=3x−11

Step: Substitute 3x−11 for y in−3x+y=−13:

−3x+y=−13

−3x+3x−11=−13

−11=−13(Simplify both sides of the equation)

−11+11=−13+11(Add 11 to both sides)

0=−2

Answer:

The scale factor is 1/3

Step-by-step explanation:

Here, we want to get the scale factor used in dilating the original segment

As we can see;

(9,3) turned to (3,1)

looking at this , we can see that both coordinate values were divided by 3

So what this mean is that the particular scale factor used is reduction by 1/3

This is the case with the other point as (-6,-9) turned to (-2,-3)

Given:

A combined figure of a triangular prism and a cuboid.

To find:

The volume of the finished object assuming it is empty inside.

Solution:

From the given figure it is clear that the dimensions of the cuboid are 6 cm, 8 cm and 5 cm.

So, the volume of the cuboid is:

[tex]V_1=length\times width\times height[/tex]

[tex]V_1=6\times 8\times 5[/tex]

[tex]V_1=240[/tex]

The volume of the cuboid is 240 cubic cm.

The area of a triangle is:

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

Thus, the base area of the triangular prism whose base is 8 cm and height 4 cm, is:

[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]

[tex]B=16[/tex]

The volume of a triangular prism is:

[tex]V_2=Bh[/tex]

Where, B is the base area and h is the height of the prism.

The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:

[tex]V_2=16(5)[/tex]

[tex]V_2=80[/tex]

Now, the volume of the given figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=240+80[/tex]

[tex]V=320[/tex]

Hence, the volume of the finished object is 320 cubic cm.

Answer:

3/8 yards

Step-by-step explanation:

3/4 yard tall and 1/2 yard wide

Multiply the two fractions

3/4 (1/2)

= 3/8 yards

If the width of the rectangular painting is one unit then the height of the painting will be 3/8 yards. Then the correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A painting is going to be reprinted as a poster.

The dimensions of the painting are 3/4 of a yard and 1/2 of a yard wide.

The poster company is trying to determine how big to make the poster For each yard of width,

Let h be the height of the poster. Then we have

[tex]\rm h \times 1 = \dfrac{3}{4} \times \dfarc{1}{2}\\\\h \ = \dfrac{3}{8}[/tex]

If the width of the rectangular painting is one unit then the height of the painting will be 3/8. Then the correct option is A.

Answer:

y = -6x - 8

Step-by-step explanation:

Two points on this line are (-3, 10) and (0, -8).  Moving from the first to the second, we see that x increases by 3 and y decreases by 18.  Thus, the rise and run are -18 and 3 respectively, so that the slope of this line is m = -6.

Adapt the slope-intercept form y = mx + b to this particular situation.  Recognize that the given (0, -8) is the y-intercept and that the slope, m, is -6.  

The equation of this line is thus

y = -6x - 8

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.

Addition and subtraction of two matrices can be done if they have the same dimensions.  This is done by simply adding or subtracting the corresponding entries in matrices.

Answer:

(9, 12)

Step-by-step explanation:

Given that :

u = (3, 4)

3u = 3(3, 4)

3u = 3(3, 4) = (9, 12)

Hence, 3u = (9, 12)

Answer:

<9, 12>

Step-by-step explanation:

Multiply X and Y values by the number of U there are.

u= <3,4>

2u=<6,8>

3u= <9,12> Multilpy By 3 to get 3u

Your answer is <9,12>.

Step-by-step explanation:

First, we can simply replace the variables with their numerical values.

Whenever you see a number with a letter (variable) in front of it, this means to multiply.

c=5 and d=4

6 × 5^2 - 5 × 4 + 8

Since there are multiple operations in this expression, we must use PEMDAS.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Now, we can apply the operations.

There are no parenthesis.

In this expression, exponents are present.

6 × 5^2 - 5 × 4 + 8

6 × 25 - 5 × 4 + 8

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There is multiplication.

6 × 25 - 5 × 4 + 8

150 - 5 × 4 + 8

150 - 20 + 8

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There is subtraction.

150 - 20 + 8

130 + 8

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There is addition.

130 + 8

158

Therefore, 6 × 5^2 - 5 × 4 + 8 = 138.

Solution

Given -

polynomial p(x) = x³ - 23x² + 142x - 120

Now see the coefficients

coefficient of x³ is 1 x² is -23 x is 142 and then -120

when you'll add this coefficients

i.e.

1-23+142-120=0

When sum of the coefficient turn out 0 then x = 1

using x=1, x-1 = 0

devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence

Given:

A right triangle with legs 5 units and 6 units.

To find:

The measure of angle opposite of side whose length is 5 units.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

Let [tex]\theta [/tex] be the missing angle. Then, for the given triangle,

[tex]\tan \theta=\dfrac{5}{6}[/tex]

[tex]\theta=\tan^{-1}\dfrac{5}{6}[/tex]

[tex]\theta=39.805571^\circ[/tex]

Round the value to the nearest degree.

[tex]\theta\approx 40^\circ[/tex]

Therefore, the measure of the required angle is 40 degrees.
