The y-value that represents the minimum point of the given function graph is -2

The minimum value of the function represented by the graph is the place where the graph has a vertex at its lowest point. In simple terms the minimum point of the graph is the coordinate of the lowest point of the graph.

Now, looking at the graph critically, we can see that it has a minimum point. We can see that the minimum point of the given graph is seen to be; (-3, -2)

This means the y-value that represents the minimum point of the given function graph is -2

Answer:

The required equation is: [tex]\mathbf{f(x)=\frac{3}{4}x-\frac{29}{4}}[/tex]

Step-by-step explanation:

We need to find equation from the table given

x     f(x)

3     -5

7     -2

11     1

15    4

We can write equation in the form of [tex]y=mx+b[/tex]

where m is slope and b is y-intercept.

Finding Slope

We can used the slope formula to find slope: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table we have: [tex]x_1=3, y_1=-5, x_2=7, y_2=-2[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-(-5)}{7-3} \\Slope=\frac{-2+5}{7-3}\\Slope=\frac{3}{4}[/tex]

So, we get slope [tex]m=\frac{3}{4}[/tex]

Now, finding y-intercept

Using the slope [tex]m=\frac{3}{4}[/tex] and point (3,-5) we can find y-intercept

[tex]y=mx+b\\-5=\frac{3}{4}(3)+b\\-5=\frac{9}{4}+b\\b=-5-\frac{9}{4}\\b=\frac{-5*4-9}{4}\\b=\frac{-20-9}{4}\\b=\frac{-29}{4}[/tex]

The y-intercept is [tex]b=\frac{-29}{4}[/tex]

So, the equation having slope [tex]m=\frac{3}{4}[/tex] and y-intercept [tex]b=\frac{-29}{4}[/tex] will be:

[tex]y=mx+b\\y=\frac{3}{4}x-\frac{29}{4}[/tex]

The required equation is: [tex]\mathbf{f(x)=\frac{3}{4}x-\frac{29}{4}}[/tex]

Answer:

f(4) = 12.2

Step-by-step explanation:

we are given that x = 4, plug in 4 into the equation

f(4) = 5(1+0.25)^(4)

f(4) = 5(1.25)^(4)

raise 1.25 to the 4th, which is equal to 2.44

Step-by-step explanation:

Inequalities help us to compare two unequal expressions. The graph for the inequality can be made as shown below.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

As per the graph let the number of pounds of quinoa be represented by x and the number of pounds of rice Celeste can buy be represented by y.

Therefore, the expression that can represent the number of pounds that Celeste can buy is,

5x + 2y

Also, it is given that Celeste can spend no more than $30. Therefore, the inequality can be written as,

5x + 2y ≤ 30

Now the graph for the inequality can be made as shown below.

The solution to the value of x is 5 < x < 15

A triangle is a shape that has 3 sides and angles. According the triangle rule, the sum of any two sides of a triangle is equal to the third.

From the given triangle shown;

15+x > 20 + 15 > 20 + x

Simplify

15+x > 20

x > 20 - 15

x > 5

Also;

20+15 > 20 + x

35 > 20 + x

35 - 20 >x

Answer:

y = 3x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (4, 6)

m = [tex]\frac{6-0}{4-2}[/tex] = [tex]\frac{6}{2}[/tex] = 3, then

y = 3x + c ← is the partial equation

To find c, substitute either of the 2 points into the partial equation

Using (2, 0 ) , then

0 = 6 + c ⇒ c = 0 - 6 = - 6

y = 3x - 6 ← equation of line

You should only use a closed dot for the symbols ≤ and ≥.

There are two types of dots used when graphing inequalities, closed and open.

So, for exampe in:

x > 3.

We would put an open dot at 3, because the value x = 3 is not a solution, but all the values at the right of the 3 are solutions.

In the other hand, for:

x ≥ 3

Now 3 is in fact a solution, so here we should use a closed dot.

Then, answering the question.

"When you graph an inequality, you used a closed dot when you use which symbols?"

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the value of £3 be = €4

So , the equation will be

The value of €1 = £ ( 3/4 )

So , the value of €24 is calculated by the equation

The value of €24 in pounds = value of €1 x 24

Substituting the values in the equation , we get

The value of €24 in pounds = £ ( 3/4 ) x 24

The value of €24 in pounds = £ 3 x 6

The value of €24 in pounds = £ 18

Answer:

[tex](f\circ g)(x)=x^2+9x+20[/tex]

Step-by-step explanation:

We have the two functions:

[tex]f(x)=x^2+5x+6\text{ and } g(x)=x+2[/tex]

And we want to find:

[tex](f\circ g)(x)[/tex]

This is equivalent to:

[tex](f\circ g)(x)=f(g(x))[/tex]

Therefore, we will have:

[tex]f(x+2)[/tex]

By substitution:

[tex]f(x+2)=(x+2)^2+5(x+2)+6[/tex]

Simplify. Square and distribute:

[tex]f(x+2)=(x^2+4x+4)+(5x+10)+6[/tex]

Rearrange:

[tex]f(x+2)=(x^2)+(4x+5x)+(4+10+6)[/tex]

Combine like terms:

[tex]f(x+2)=(f\circ g)(x)=x^2+9x+20[/tex]

Answer:

D. (3, -1)

Step-by-step explanation:

y = 2x - 7 and 4x + y = 11 are two given equation

Now, Name the equation

y = 2x - 7 ...(1)

4x + y = 11 ...(2)

Then, Put the value of y in equation (2)

4x + y = 11

4x + (2x - 7) = 11

4x + 2x - 7 = 11

6x - 7 = 11

6x = 11 + 7

6x = 18

x = 18/6

x = 3

Here, put the value of x in equation (1)

y = 2x - 7

y = 2(3) - 7

y = 6 - 7

y = - 1

Thus, (3, - 1) pair makes both of these equations true
