Answer 1

Answer:

x = 4

Step-by-step explanation:

Because we know both figures have the same perimeter, we can set them equal to each other.

3x + 4 + 5x + 1 + 2x + 5 = x + 13 + x + 13 + 2x + 2x

10x + 10 = 6x + 26 (Added like terms.)

4x + 10 = 26 (Subtracted 6x on both sides.)

4x = 16 (Subtracted 10 on both sides.)

x = 4 (Divided 4 on both sides.)

What are the two question that you want to ask to clarify the process of translating real life situation to rational function​

Answers

Answer and Step-by-step explanation:

The rational function is the function that can be written in terms of ratio that contains two polynomial functions in which the denominator is not equivalent to zero

Now the two questions that should be asked which are as follows:

1. Translate real life to rational functions.

2. Process for translate to real life to rational functions

These two questions should be asked

The two question that I want to ask to clarify the process of translating real life situation to rational function are

How can I tell if a function is rational or not?How do rational functions apply in real life situation

For better understanding, lets explain what rational function means.

Rational function is simply known to be the function of the form f(x)= p(x)/q(x) where p(x) and q(x) are polynomial and q(x) cannot equal zero or simply say it is a function gotten when we divides one polynomial by another. in real life, rational functions are often used in modeling more complex equations in science and engineering.

From the above we can therefore say that the answer The two question that I want to ask to clarify the process of translating real life situation to rational function are

Answers

The features of the quadratic function f(x) = x^2 + 10x + 21  are Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5 so option (A) will be correct.

What is a quadratic equation?

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

For example 3x² + 6x + 8 = 0 here x has highest term as 2 and coefficient of x² is not zero.

The standard form of a quadratic equation is ax² + bx + c

The x vertex is given -b/2a

So,

x-vertex = -10/2 = -5

So y = (-5)² + 10(-5) + 21 = -4

So vertex is (-5, -4)

The Y-intercept is given as (0,y)

So,

y = 21

Therefore

y-intercept = (0,21)

the x-intercept is given as (x,0)

So,

x = -7 , -3

Therefore

x-intercepts = (-7,0) and (-3,0)

The Axis of symmetry is given by -b/2a

So,

⇒ -10/2 = -5

Hence "Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5".

If license plates in Idaho have 4 numbers followed by 2 letters, how many different plates can be made?
a. 6,760,000
O b. 676
O c. 260
O d. 17,576,000

Answers

the answer is d. 17,576,000

The number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters is 6,760,000, option a is correct.

To determine the number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters, we need to consider the possibilities for each element.

For the numbers, we have 10 options (0-9) for each of the four positions, resulting in a total of [tex]10^4 = 10,000[/tex] combinations.

For the letters, we have 26 options (A-Z) for each of the two positions, resulting in a total of [tex]26^2 = 676[/tex] combinations.

To find the total number of different plates, we multiply the number of possibilities for each element:

[tex]10,000 \times 676 = 6,760,000[/tex].

Hence, option a is correct.

rewrite

[tex]x-2=-54[/tex]

add 2 to both sides

[tex]x-2+2=-54+2\\x=-52[/tex]

Answer:

[tex]x=-52[/tex]

Step-by-step explanation:

[tex]\frac{1}{3} x-\frac{2}{3} =-18[/tex]

Add [tex]\frac{2}{3}[/tex] to both sides of the equation:

[tex]\frac{1}{3} x=-18 +\frac{2}{3}[/tex]

Simplify [tex]-18+\frac{2}{3}[/tex] by multiplying [tex]-18[/tex] in fraction form [tex]-\frac{18}{1}[/tex] to get a common denominator so you can add the two fractions:

[tex]-\frac{18}{1}[/tex] × [tex]\frac{3}{3}=-\frac{54}{3}[/tex]

Now add the two fractions:

[tex]-\frac{54}{3} +\frac{2}{3} =-\frac{52}{3}[/tex]

Now write the simplified equation:

[tex]\frac{1}{3} x=-\frac{52}{3}[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]\frac{1}{3}[/tex]:

[tex]x=-\frac{52}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex]

Use the reciprocal of the dividend ([tex]\frac{1}{3}[/tex]), and multiply by your divisor:

[tex]x=-\frac{52}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]x=-\frac{156}{3}[/tex]

Simplify the fraction by dividing [tex]-156[/tex] into [tex]3[/tex]:

1. Maya's ice cream machine makes 10 cups of ice cream from 0.5 cup of sugar. How many cups of ice cream can be made with 5 cups of sugar?​

Answers

Answer:

100

Step-by-step explanation:

Since ten cups of ice cream is made from .5 cups of sugar, lets first find out how many cups of ice cream can be made form one cup of sugar

.5*2=1

10*2=20

Since the ratio of sugar to ice scream is .5/10 if you do anything to the top you need to do it to the bottom

so now you have 1/20

for every one cup of sugar there are 20 cups of icecream

now you need to multiply both top and bottom by five

1*5=5

20*5=100

5/100

You can make 100 cups of ice cream

*don't forget to label your answer with cups of ice cream*

100 cups of ice cream can be made with 5 cups of sugar.

What are comparing quantities?

Comparing quantities is the qualitative relation between two quantities which reflects the relative size of both the quantities.

It is given that,

10 cups of ice cream requires = 0.5 cup of sugar

⇒ 1 cup of sugar = 10/0.5 cups of ice cream

⇒ 1 cup of sugar = 20 cups of ice cream

Hence we see that Maya's ice cream machine makes 20 cups of ice cream from 1 cup of sugar.

Similarly, 5 cups of sugar = 5 x 20 cups of ice cream

⇒ 5 cups of sugar = 100 cups of ice cream

Therefore,100 cups of ice cream can be made with 5 cups of sugar.

Step-by-step explanation:

5x+192−321+13=−12x

Step 1: Simplify both sides of the equation.

5x+192−321+13=−12x

5x+192+−321+13=−12x

(5x)+(192+−321+13)=−12x(Combine Like Terms)

5x+−116=−12x

5x−116=−12x

Step 2: Add 12x to both sides.

5x−116+12x=−12x+12x

17x−116=0

Step 3: Add 116 to both sides.

17x−116+116=0+116

17x=116

Step 4: Divide both sides by 17.

17x/17=116/17

x = 116/17
