Geometry is so hard pls help

Answer:

-55

Step-by-step explanation:

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?"

The ≤ and ≥ symbols.

thats the answer

(2,4)

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

f(4) = 5(2.44)

f(4) = 12.2

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]

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

x < 15

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

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

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]

Probabibility = 1/6 * 1/6 = 1/36 = 2.77%.

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

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

Therefore , the value of €24 in pounds is £ 18

Hence , The value of €24 in pounds is 18 pounds or £ 18

The cost and the patient's condition are other factors. For instance, a doctor might decide against suggesting surgery if a patient has very bad health because of the potential for additional difficulties. Then, we won't be able to tell if a higher death rate is a result of the therapy or the participants' pre-existing health.

Any condition that necessitates a localised treatment, such as surgery or one of the many vascular procedures or radiation methods, is referred to as a surgical disease. A more comprehensive, pharmacological strategy to treat a medical issue is required.

"Non-surgical" treatments are also referred to as "non-invasive" procedures in the cosmetic industry. These techniques don't need cutting the skin or inserting tools into the body, in contrast to "invasive" surgical therapies.
