Terri's project for the Math Fair is a magnificent black box that she called a function machine. If you put 3 into her machine, the output is 8. If you put in 10, the output is 29; and if you put in 20, the output is 59. Homework help

a. What would her machine do to an input of 5? What about -1? What about x?

b. Write an equation for Terri's machine

Answers

Answer:

a) An input of 5 gives an output of 14. An input of -1 gives an output of -4.

An input of x gives an output of 3x - 1

b) y = 3x - 1

Step-by-step explanation:

The pattern is that you multiply the number by 3 then subtract 1.

3*3 - 1 = 9 - 1 = 8

10 * 3 - 1 = 30 - 1 = 29

20 * 3 - 1 = 60 - 1 = 59

So:

For an input of 5,

5 * 3 - 1 = 15 - 1 = 14

For an input of -1:

-1 * 3 - 1 = -3 - 1 = -4

For an input of x:

x * 3 - 1 = 3x - 1

So the equation is

b) y = 3x - 1

where x is the input value.

7x - 5x/3 (20/x - 8) -48=0

Answers

Hello!

Let’s work this out step by step.

The first thing you want to do is move that 48 to the other side. To do that, add 48 to both sides:

7x-5x/3(20x-8)=48

Now, the equation isn’t equal to zero… so it is solvable! Remember in order of operations: PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction. So, let’s start by multiplying the (-5x/3) by the components inside the parentheses to get rid of the parentheses altogether!

7x-100x/3x+40x/3=48

Since both the numerator and denominator have an “x” in them in “100x/3x”, you can cancel out the “x”s to just get 100/3, which is 33.333333

7x-100/3+40x/3=48

Let’s get rid of that 100/3 by adding it to both sides.

7x+40x/3=81.33333333333

Transform 7x to a fraction that can be added to 40x/3 (common denominators)

7x=7x/1

7x/1* (3/3)= 21x/3

Now, add the two fractions together

21x/3+40x/3= 61x/3

61x/3=81.333333333

Get rid of the 3 by multiplying on both sides:

61x= 244

Divide by 61 to get x

X=4

Answer:

Step-by-step explanation:

So because it is a repeating decimal we have to round it off first. We can round it to the nearest hundredth making it 0.68. This then becomes [tex]\frac{68}{100}[/tex] as a fraction which can be reduced to its lowest terms by dividing both the numerator and denominator by 4 and then it becomes [tex]\frac{17}{25}[/tex].

C. 75
D. 100

Answers

the answer is 75 because 180 is a full circle. so 180 minus 105 since it’s the opposite side which makes b 75

Answer: C. 75

Concept:

Here, we need to know the idea of quadrilaterals in a circle.

The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

Given information

The opposite angle of b = 105°

Given expression

b + opposite angle of b = 180°

Substitute values into the expression

b + 105 = 180

Subtract 105 on both sides

b + 105 - 105 = 180 - 105

b = 75°

Answer:

Step-by-step explanation:

5t-8 and 68 are the angles of a straight line so their addition will be180°.

5t-8 + 68 = 180

5t + 60 = 180

5t = 180-60

If 2x - 4= 16 for some value of x, then
what is the value of x + 2 for the same
value of x?

Answers

Answer:

Step-by-step explanation:

2x - 4= 16

Divide by 2

2x/2 -4/2 = 16/2

x -2 = 8

Add 4 to each side

x-2+4 = 8+4

x+2 = 12

Final Answer: 12
Step 1:
2x - 4 = 16
+4 = +4
2x = 20
2x/2 = 20/2
x = 10

Step 2:
x + 2
10 + 2 = 12

So your answer is 12.

Find three consecutive integers that have the sum of -402

Answers

Answer:

-135, -134, -133

Step-by-step explanation:

Hi there!

Let x be equal to the first integer in the set of three consecutive integers.

Let x+1 and x+2 be the consecutive integers.

We're given that they have a sum of -402.

We can construct an equation:

[tex](x)+(x+1)+(x+2)=-402[/tex]

Combine like terms:

[tex]x+x+1+x+2=-402\\x+x+x+1+2=-402\\3x+3=-402\\3x=-405\\x=-135[/tex]

Therefore the first integer is -135.

The next two consecutive integers after -135 is -134 and -133.

Therefore, the three consecutive integers are -135, -134 and -133.

Answers

Answer:

280/8 = 35 "sets"

35*3 = 105 Constance

35*5 = 175 vowels

Step-by-step explanation:

There are 105 consonants and 175 vowels in a paragraph.

What is vowels and consonants?

Vowels (such as a, e, I o, and u) and consonants combine to form words (the rest of the alphabet). The letter "y" is a little odd since it can function as a vowel or a consonant depending on the context. Spelling will be made easier for you if you understand how vowels and consonants combine to form words and sounds.

a speaking sound made by people when their teeth, tongue, or lips obstruct the breath from leaving their mouths. grammar. Except for the English vowels a, e, I o, and u, a consonant is a letter that represents a sound made in this way.

Given:
The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph.

First to find the number of sets in the paragraph as

[tex]\frac{280}{3+5} = \frac{280}{8} = 35[/tex]

Therefore, there are 35 sets in the paragraph.

So, 35 x 3 = 105 are consonants and

35 x 5 = 175 are vowels.
