Answer:

(-1,1)

Step-by-step explanation:

Answer:

(- 1, 1 )

Step-by-step explanation:

2x - 3y = - 5 → (1)

3x + y = - 2 → (2)

multiplying (2) by 3 and adding to (1) will eliminate y

9x + 3y = - 6 → (3)

add (1) and (3) term by term to eliminate y

11x + 0 = - 11

11x = - 11 ( divide both sides by 11 )

x = - 1

substitute x = - 1 into either of the 2 equations and solve for x

substituting into (2)

3(- 1) + y = - 2

- 3 + y = - 2 ( add 3 to both sides )

y = 1

solution is (- 1, 1 )

Answer: 68 degrees

Step-by-step explanation:

Let the measure of the angle be x.

The supplement of the angle is 180 - x as supplementary angles add up to 180 degrees.

The complement of the angle is 90 - x as complementary angles add up to 90 degrees.

We can set up an equation.

180 - x = 46 + 3*(90-x)

180 - x = 46 + 270 - 3x

Combine like terms:

2x = 136

Divide both sides by 2:

x = 68

What are supplementary and complementary angles?

The supplement of an angle (180 - x) is [=] 46 more than 3 times the complement (90-x):

180 - x = 3 (90 - x) +46

Now, solve for x:

180 - x = 3 (90 - x) +46

180 - x = 270 - 3x +46

180 - x = 316 -3x

-x = 136 -3x

2x = 136

x = 68

The angle is 68°

Answer:

from the lines i you can see that these triangles are the same so that means the other angle is 74 so since we know that the angles of a triangle always add up to 180

5x+3x+2+74=180

Answer:

it is more intense by 3.0

Step-by-step explanation:

Answer:

d = 90°

e = 41°

f = 139°

Step-by-step explanation:

d + 90° = 180° (Angles in linear pair)

-> d = 180° - 90°

-> d = 90°

e = 41° (vertical angles)

f + 41° = 180° (Angles in linear pair)

-> f = 180° - 41°

-> f = 139°

Answer:

Let A represent the center of the circle. Let the point B be a point at the intersection of the one end of the chord and the edge of the circle. Finally, let C represent a point between the center of the circle and the midpoint of the cord. The triangle ABC is a right triangle with a 90 degree angle at ACB. Since the cord length is 30, the bisected segment BC is length 15 .

(length AB)^2 = (length BC)^2 + (length AC)^2

17^2 = 15^2 + (length AC)^2

289 = 225 + (length AC)^2

add -225 to each side

64 = (length AC)^2

take square root of each side

8 = length AC

Answer:

The volume of the composite figure is approximately 337.27 m³

Step-by-step explanation:

The given parameters are;

The length of the cylinder, L = 15 meters

The diameter of the cylinder, D = 7 meters

The base length of the square prism, B = 4 meters

We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder

Therefore, we have;

The volume of the composite figure = The volume of the cylinder - The volume of the square prism

The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³

The volume of the square prism = B² × L = 4² × 15 = 240 m³

∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³

The volume of the composite figure ≈ 337.27 m³.

Step-by-step explanation:

Three students is part of her sample is students 1, 10, and 20.

We have given that,

Karen created a sample of 20 students from a population of 100 in the following way.

First, she gave each student a unique number from 1 to 100. She then obtained a list of 20 randomly generated numbers between 1 and 100.

She used these numbers to identify which students to select. Here is the list of random numbers.

We have to determine the three students are part of her sample.

A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol S.

Therefore option A is correct.

Answer:

It would not be any of those answers. it would be 106 :) Its negative numbers divided

The value of expression is,

⇒ - 27 / 79

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 27 ÷ (- 34 - 45)

Now, We can simplify as;

⇒ 27 ÷ (- 34 - 45)

⇒ 27 ÷ - 79

⇒ - 27 / 79

Thus, After simplification, we get;

⇒ - 27 / 79

The similar triangles ABC and DEF may or may not have equal lengths

Janette's claim that triangles ABC and DEF are similar triangle is true

Start by calculating the length of the third sides using the Pythagoras theorem.

[tex]a^2 = b^c + c^2[/tex]

For triangle ABC, we have:

[tex]AC^2 = 20^2 + 21^2[/tex]

[tex]AC = 29[/tex]

For triangle DEF, we have:

[tex]58^2 = 40^2 + EF^2[/tex]

This gives

[tex]EF^2 = 58^2 - 40^2[/tex]

[tex]EF = 42[/tex]

So, we have the following corresponding lengths on both triangles

Triangle ABC             Triangle DEF               Common ratio

20                                      40                                    2

21                                       42                                    2

29                                      58                                    2

Since the common ratios are the same, then the triangles are similar

Hence, Janette's claim is true

Step-by-step explanation:

They substitute =AC for =12 from step 1.

just replace x with the highest value

f([tex]x_{max}[/tex]) = 3(2) + 2

= 8

The greatest value in the range of f(x) is 8.

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The range of a function is defined as the set of all the possible output values that are valid for the given function.

WE are given that the domain for f(x) = 3x + 2 is -3 ≤ x ≤ 2.

We just need to replace x with the highest value;

f(2) = 3(2) + 2
