does anyone know how to solve this pre cal question Im super confused

Answer:
112

Step-by-step explanation:

Just plug in 2 into the equations and then multiply them together at the end.

g(2) = 3(2) + 1
       = 6 + 1
       = 7

f(2) = (2)² + 3(2)²
      = 4 + 3(4)
      = 4 + 12
      = 16

g(2) × f(2)
    7 × 16 = 112

The actual area of Zahra's office is 50ft².

Proportions are used to solve scale problems using the rule of three.

The drawing is scaled from 6 cm to 15 ft, which means that each 6 cm represents 15 ft of real dimensions.

The length in the drawing is 4 cm, so:

Cross multiplication is used:

Her actual office measures are 10 feet long.

The width is 2 cm, so:

Cross multiplication is used:

Her actual office measures are 5 feet wide.

Formula of area: l × b

Therefore, the actual area of Zahra's office is 50ft².

examples of equivalent equations

Equivalent equations are algebraic equations that have identical solutions or roots.

Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.

Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

The first step is to know the rules of equivalent equations:

Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.

Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

Raising both sides of the equation to the same odd power or taking the same odd root will produce an equivalent equation.

If both sides of an equation are non-negative, raising both sides of an equation to the same even power or taking the same even root will give an equivalent equation.

Solution :

10+ 4(-8q - 4)=0

10+ 4(-8q ) = 4

10-24 p =4

10 -4 =24 p

6 =24 p

6/24 = p

1/4 = p

The number of volunteers who are selected for the tennis tournament is 40 as calculated by the fractions.

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction in spoken English refers to the number of components of a particular size.

A fraction consists of a numerator and a denominator. The numerator divided by the denominator is known as a fraction.

Compound fractions, complicated fractions, and mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.

There are a total of 200 applicants who volunteered at the tennis tournament.

1/4 of the volunteers were successful.

Number of successful applicants= [tex]\frac{1}{4} \times 200=50[/tex]  

Now 1/5 of the successful candidates could not complete the training.

Number of unsuccessful candidates= [tex]\frac{1}{5} \times 50=10[/tex]

Number of Volunteers selected to help at the tournament= 50-10=40

Hence 40 candidates were selected to help at the tournament.

Disclaimer: The complete correct question is :

200 applicants applied to volunteer at an international tennis tournament.1/4th of the applicants were successful. However, of the successful applicants, 1/5th couldn’t make all the training sessions and were discounted. How many were selected to help at the tournament?

The price of the file is Rs 89.18  and pen is Rs 109.43 as calculated from a linear equation .

An equation is said to be a linear equation if the maximum power of the variable is consistently 1.

Let us consider the cost of the file be x dollars.

Then cost of the pen = x + 20.25

And cost of the book = x + 20.25 - 13.20 = x - 7.05

The cost of all three items together is 280.75

Now we will form a linear equation in x to find the cost of each of the pen, book and file separately.

x + x + 20.25 + x - 7.05 = 280.75

or, 3x + 13.20 = 280.75

or, 3x = 267.55

or, x = 89.18

Hence the cost of the file is approximately Rs 89.18

Cost of the pen = 89.18 + 20.25 = Rs 109.43

Cost of the book =  x - 7.05 = 89.18 - 7.05 = Rs 82.13

The parent function of the function y =  2x² - 6 is y = x². The explanation about transformation is given.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

We have the quadratic function,

y = 2x² - 6

To find the parent function:

Add

y(x) = 2x²

Divide by 2

y(x') = x²

If there is a horizontal or vertical shift, reflection around the x-axis or y-axis, or vertical stretch, the transformation may be found by comparing the equation to the parent function.

Parent Function:

y = x²

Horizontal Shift: None

Vertical Shift: Down 6 Units

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Stretched

Therefore, the parent function is y =  x².

Step-by-step explanation:

to be a function every value of x must have exactly one value of y.

in other words, if you create a vertical line and move it across the whole chart (e.g. from left to right), this line must not even once intersect the function curve more or less than once.

so, this is clearly a given here. yes, it is a function.

the domain is the interval or set of all valid x (input) values. and that starts on the right with x = 5 (included in the function indicated by the filled dot). and it goes endlessly to the left. that means -infinity (but not included as "infinity" is only a symbol but not a number).

-infinity < x <= 5

the range is the interval or set of all valid y (function result) values.

and that starts on the top with y = 2 (included). and it goes endlessly down. that means again -infinity (not included).

-infinity < y <= 2

By dimensional analysis and the conversion factor between feet and yards, we find that a square yard is equal to a quantity of 3² square yard, that is, a quantity of 9 square feet. (Correct choice: C)

In accordance to dimensional analysis, area units are equal to the square of length units, that is, length unit multiplied by length unit. That is:

[A] = [L] × [L] = [L]²

Where:

L - Length unit

A - Area unit

If a yard is equal to a quantity of three feet, both length units, then a square yard is equal to a quantity of 3² square feet, that is, a quantity of 9 square feet, both area units. Therefore, we can construct the following conversion factor:

1 square yard = (3 feet)² = 9 square feet

I hope this helps good luck

The measure of the angle 1 is 95.05 degrees.

It is given in the question that:-

Measure of Angle 1 = 7x + 10

Measure of Angle 2 = 3x + 4

Measure of Angle 3 = 3x + 8

All the angles are supplementary.

We know that, the sum of all the supplementary angles is equal to 180 degrees.

Hence, we can write,

(7x + 10) + (3x + 4) + (3x + 8) = 180

(7x + 3x + 3x) + (10 + 4 + 8) = 180

13x + 22 = 180

13x = 180 - 22

13x = 158 degrees

x = 158/13 degrees

x = 12.15 degrees (rounded off  to the hundredths place )

Hence,

Measure of angle 1 = 7x + 10 = 7(12.15) + 10 = 85.05 + 10 = 95.05 degrees.
