Step-by-step explanation:

The value of the expression |5x + 1 / 2y²| when x = 3 and y = 2 will be 2.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The expression is given below.

⇒ |5x + 1 / 2y²|

The value of the expression at x = 3 and y = 2, then we have

Answer: No, a triangle is not possible

The two smaller sides add to 4+5 = 9 which is not larger than 20. For a triangle to be possible, we need to be able to add 2 sides to make them longer than the third side. This is an application of the triangle inequality theorem.

Albert has 40 toy cars. Brad has 15 fewer toy cars than Albert, but 7 more than Chris. How many toy cars do they have all together?

Answers

Answer:

83

Step-by-step explanation:

40 - 15 = 25

25 - 7 = 18

40 + 25 + 18 =

83

We know that Albert has 40 toy cars.

If Brad has 15 fewer cars than Albert, Brad has 40 - 15 or 25 cars.

Now, we know that Chris has 7 fewer cars than Brad.

So Chris would have 18 cars.

Altogether, they would have 40 + 25 + 18 cars or 83 cars.

Jamaal spent x minutes today practicing his guitar and y minutes today on homework. If the total time he spent on both is 45 minutes or more, which inequality best represents his practice time?

x + y < 45
x + y > 45
x + y ≤ 45
x + y ≥ 45

Answers

Answer:

x + y ≥ 45

Step-by-step explanation:

This is because the total amount of minutes could be equal to 45, meaning your inequality sign has to have a line underneath it.

Additionally, x + y is greater than or equal to because the amount could be more than 45... therefore, 45 is not greater than x + y

Hi there! Hopefully this helps!

If the total time he spent on both is 45 minutes or more, the answer is:

Carly is traveling to visit family. She drives x miles on the first day and y miles on the second day for a total of 800 miles. What are the domain and range of this relationship?

Answers

Answer:

The domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Step-by-step explanation:

We are given that Carly is traveling to visit family.

She drive distance on first day = x

She drive distance on second day = y

We are also given that Carly is travelling a total of 800 miles.

So,x+y=800

We are supposed to find domain and range of this relationship.

y=800-x

Domain : (-∞,∞)

Range:(-∞,∞)

Hence the domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Answer:

B. (m-1)(m-8)

Step-by-step explanation:

The factors of 8 (constant term) are

{(1,8), (2,4)}, from which we see that 1+8 = 9, the absolute value of the coefficient of the second term.

Therefore we can group the expression as

m^2 - 9m + 8

= m^2-m - (8m -8)

then factor each group

= m(m-1) - 8(m-1)

and factor out (m-1)

= (m-1)(m-8)

(m-1)(m-8) is the correct answer

O AX) = (7) . (3)X-1
Rx) = (2) (+)*-1

Answers

Answer:

a(n) = 7*2^(n - 1)

Step-by-step explanation:

The first term of the given geometric sequence, 7, 14, 28, 56, 112, ... , is 7, and the common ratio is 2.  Each new term is twice the previous term.

Thus the general formula for the geometric sequence becomes

a(n) = 7*2^(n - 1).

As a check, let's see whether this formula correctly predicts the fourth term (56):  Here n = 4, and so a(4) = 7*2^(4 - 1) = 7*2^3 = 7*8 = 56.  Yes.

Answer:

f(x) = (7) ∙ (2)x–1

Step-by-step explanation:

The first term in the sequence is 7, and the common ratio is 2. Using the explicit formula and writing it in function notation results in f(x) = (7) ∙ (2)x–1.

A. 14
B. 91
C. 21
D. 127

Answers

Answer:

  D.  127°

Step-by-step explanation:

The exterior angle (x) is the sum of the remote interior angles (y, z).

Setup

  x = y +z

  (197 -5n) = (6n +22) +(n +7) . . . . . substituting the given expressions

Solution

Eliminating parentheses and collecting terms, we have ...

  197 -5n = 7n +29

  168 = 12n . . . . . . . . . add 5n-29

  14 = n . . . . . . . . . . divide by 12

Then the measure of remote exterior angle x is ...

  m∠x = (197 -5(14))° = (197 -70)°

  m∠x = 127°

The length of a rectangular picture is 5 inches more than three times the width. Find the dimensions of the picture if its perimeter is 74 inches.

Answers

Answer:

Length = 29 inchesWidth = 8 inches

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length of the rectangle

w is the width

From the question

length of a rectangular picture is 5 inches more than three times the width is written as

l = 5 + 3w

Now substitute this into the above equation

Perimeter = 74 inches

74 = 2(5 + 3w) + 2w

74 = 10 + 6w + 2w

8w = 74 - 10

8w = 64

Divide both sides by 8

w = 8 inches

Substitute w = 8 into l = 5 + 3w

That's

l = 5 + 3(8)

l = 5 + 24

l = 29 inches

Length = 29 inchesWidth = 8 inches

Hope this helps you

What is the reference angle for 4560 degrees?

Answers

Answer:

30 degrees

Step-by-step explanation:

Answer:

30°

Step-by-step explanation:

4560° ÷360°= 12.667 (5 s.f.)

This means that the angle 4560° goes around from quadrant I to quadrant IV 12 times, before coming back to quadrant I. The 13th round does not reach quadrant IV.

So, let's find the angle covered after the 12 full rounds.

12 ×360°= 4320°

remaining angle left

= 4560° -4320°

= 240°

See the attached picture to see where 240° will lie in the quadrants. It lies in quadrant III and its reference angle is the red coloured angle in the picture.

Reference angle

= 270° -240°

= 30°

In this case, you can consider 9 meters as the length, 5 meters as the height, and 8 meters as the width (but it doesn't really matter which dimensions are which since you are just multiplying them all together).
