Answer:

4 chairs for every table.

Step-by-step explanation:

Write a ratio:

12 chairs : 3 tables = 4 chairs : 1 table

4 chairs for every table.

There are 4 chairs for every table is equivalent to the given sentence " 12 chairs for every 3 tables"

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

The given statement is "12 chairs for every 3 tables"

According to the given question, translate the phrase into an algebraic form :

We can write a proportion as

12 chairs : 3 tables = 4 chairs : 1 table

12 / 3 = 4 / 1

This means 4 chairs for every table.

Therefore, there are 4 chairs for every table is equivalent to the given sentence " 12 chairs for every 3 tables"

#SPJ3

Answer: VA: x = {-5, 5), HA: y = 0, Zeros: x = 0

Step-by-step explanation:

[tex]f(x) = \dfrac{5x}{x^2-25}[/tex]

Vertical asymptotes: The denominator cannot equal zero.

x² - 25 = 0  

(x - 5)(x + 5) = 0

x = 5, x = -5

Horizontal Asymptote: Let m represent degree of numerator and n represent the degree of the denominator.

For the given equation, m = 1 and n = 2 so we use option 3 --> y = 0

Zeros: Set the equation equal to zero and solve for x.

[tex]0=\dfrac{5x}{x^2-25}[/tex]

Multiply both sides by x²- 25   -->    0 = 5x

Divide both sides by 5       -->          0 = x

Using function concepts, it is found that:

The function is given by:

[tex]f(x) = \frac{5x}{x^2 - 25}[/tex]

Applying the subtraction of perfect squares, the function will be given by:

[tex]f(x) = \frac{5x}{(x - 5)(x + 5)}[/tex]

The zero is the value of x for which:

[tex]f(x) = 0[/tex]

In a fraction, it is when the numerator is zero, thus:

[tex]5x = 0[/tex]

[tex]x = \frac{0}{5}[/tex]

[tex]x = 0[/tex]

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator, thus:

[tex](x - 5)(x + 5) = 0[/tex]

[tex]x = \pm 5[/tex]

The horizontal asymptote is:

[tex]y = \lim_{x \rightarrow \infty} f(x)[/tex]

Hence:

[tex]y = \lim_{x \rightarrow \infty} \frac{5x}{x^2 - 25} = y = \lim_{x \rightarrow \infty} \frac{5x}{x^2} = y = \lim_{x \rightarrow \infty} \frac{5}{x} = 0[/tex]

Put a square which covers this triangle

Find the area of the rectangle which is 20

Half it which is 10

Now you have the area which is 10

Answer: The other answer is incorrect!

Step-by-step explanation:

An easier way is just imagine it being straight and not slanted. Counting the base its 3blocks and counting from the highest point all the way to the base its 4 blocks. Base=3 blocks and height=4 blocks. Substituting into the tirangle area formula which is b(h)/2 (base times height divided by 2).

You have 3x4=12.

Then 12/2=6 blocks

Therefore the area of the given triangle is 6 blocks squared (din)t forget the square).

The other answer is incorrect because this triangle is not half of this rectangle and in this question it’s just a grid (we have to use the grid)!

Trust me I know this.

they share the same min of -3

Answer:

The minimum values are equal

Step-by-step explanation:

The minimum for f(x) = (4,-3)  since the parabola is written in vertex form

y = a(x-h)^2 +k

The minimum is at x=4 the the y value is -3

Looking at the graph for g(x) the minimum is at x=-3 y = -3

Since the y values are equal

The minimum values are equal

Answer:

f(x) = x^2 + 11x + 18.

Step-by-step explanation:

As the zeroes are -2 and -9 the factored form  is

f(x) = a(x - (-2))(x -  (-9))   where a is some constant.

As we want any quadratic function with theses zeros we  can let a = 1 so:

f(x) = (x + 2)(x + 9)

f(x) = x^2 + 2x + 9x + 18

f(x) = x^2 + 11x + 18.

The required quadratic function is given as x²+11x+18 = 0,

Given that,
To write a quadratic function f whose zeros are -2 and -9

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
x = -2 and x = -9
x  2 = 0  and x + 9 = 0
The function is given as,
(x + 2)(x + 9) = 0
x²+11x+18 = 0,

Thus, the required quadratic function is given as x²+11x+18 = 0,

Add 1 to both sides

Multiply both sides by 4

Take the square root of both sides

Subtract 5 from both sides

In this problem, you are trying to isolate the x. In order to do that you have to get rid of all the other numbers surrounding it. The first thing you're going to do is move the 1. To get rid of the -1 you have to do a +1. What you do to one side you have to do to the other. Therefore, you have to add +1. Next, you will move the 1/4 by multiplying by the reciprocal which is 4 (because 1/4 x 4 = 1, this gets rid of the 1/4 on the left side). After that you will do the opposite of square, which is to take the square root. Lastly, you will subtract the five for the same reason you added the 1.

The attached image in conjunction with the question is shown in the file below.

We can see from the RT segment that the equation given can be expressed as:

[tex]\mathbf{2x+3x = 10}[/tex]

so; if we solve for x ; we have ;

[tex]\mathbf{5x= 10}[/tex]

divide both sides by 5 ; we have:

Answer: 72 beads

Step-by-step explanation:

From the question, we have the information that Johnathan picked colored beads from a jar 50 times and replaced the bead each time. Jonathan picked a red bead 12 times, yellow bead 14 times, and a blue bead 24 times.

Out of 50 picks, the following beads were picked:

Red = 12

Yellow = 14

Blue = 24

Total = 50

Fraction of blue bead = 24/50 × 100

= 48%

The blue beads that Johnathan will pick out of 150 beads will be:

= 48% of 150

= 48/100 × 150

= 0.48 × 150

= 72 blue beads

Jonathan will pick 72 blue beads out of 150 beads.

Explanation:

Just take the width of the rectangle and multiply each number by 2, including the exponent.

Answer & Step-by-step explanation:

We can solve this problem by multiplying the the expression by 2 one term at a time just like it is shown in the diagram. Your exponent will remain the same.

(5x² * 2) + (-2x * 2) + (3 * 2)

10x² - 4x + 6

Answer:

An even number is a number that can be divided into two equal halves.

Also even numbers end in one of these digits: 0, 2, 4, 6, or 8

12 + 12 + 12 + 12 = 48

48 with the digit 8

48 divided in half gives two equal halves:

48/2 = 24

The number 24 can be added twice to check that the answer is correct:

24 + 24 = 48

So to summarize:

The sum of 12 + 12 + 12 + 12 is an even number because it can be equally divided in two halves and it ends in the digit 8.

For every hour she earns 12$

The correct statement about the graph is for each hour Lisa earns $12. This can be obtained by studying the graph.

By observing the graph we can say that Earnings are directly proportional to Time.

Taking any point on the graph, for example (24,2) we can say that for 2 hours Lisa earns $24 ⇒ for 1 hour she earns $12 .

Hence the correct statement about the graph is for each hour Lisa earns $12.
