Answer:

-3(2) x 2 -7 = -6x2-7 =-19

Step-by-step explanation:

The value of f(2) for the given function f(x) = -3x² – 7 will be -19.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given function,

f(x) = -3x² – 7

Put x = 2

f(2) = -3(2)² - 7

f(2) = -2(4) - 7

f(2) = -8 - 7 = -15

Hence "The value of f(2) for the given function f(x) = -3x² – 7 will be -19".

The answer to this question is the letter D.

The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.

How to find the correlation coefficient for the data table -0.93,-0.27, 0.27, 0.93?

This is because the correlation coefficient focuses on the linear relationship between two variables.

numbers between -1 and 1 should be one of the values related to the bill. As you can the letter D is the closest and most realistic answer.

Answer: Infinite solutions

Step-by-step explanation:

[tex]8-(2x-9)=17-2x[/tex]

Begin by distributing the negative into the parenthesis.

[tex]8-2x+9=17-2x[/tex]

Combine like terms;

[tex]17-2x=17-2x[/tex]

Subtract 17

[tex]-2x=17-17-2x[/tex]

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

Add 2x

[tex]-2x+2x=0\\0=0[/tex]

Equation: 8 - (2x - 9) = 17 - 2x

First, we distribute the - sign.

8 -2x + 9 = 17 - 2x

Then, we combine like terms if there any on both sides.

17 - 2x = 17 - 2x

Now, we can see the equations are equal to each other.

However, we can go a step further and solve for x.

17 - 2x = 17 - 2x

Subtract 17 from both sides.

-2x = -2x

Divide both sides by -2.

x = x

Therefore, x has no value or is 0.

x=10 if you are looking for the x value

Answer: 25

Step-by-step explanation: In this problem, we're given a diagram and were asked to find the value of x.

Since the two lines in the figure intersect, we know that they form vertical angles and remember that vertical angles are always congruent, or of equal measure.

Therefore, since we know that one angle measures 75° and the other angles measures 3x°, we can setup the equation 75 = 3x.

To get x by itself since 3 is being multiplied by x,

divide both sides of the equation by 3.

On the left, 75 divided by 3 is 25

and on the right, the 3's cancel.

So the value of x in the diagram shown is 25.

Answer:

54

Step-by-step explanation:

Since they don’t overlap, just find the area of each rectangle and add it together. for example, the first rectangle will be 30 because 3x10=30. the second rectangle will be 24 because 3x8=24. 30+24=54. hope this helped :)

Answer:

s = 15

Step-by-step explanation:

Using the given information to solve for s, the work would look something like this:

s + 53 =g, g=68

s + 53 = 68 (Subtract 53 from both sides to get s by itself)

53 - 53 = 0, 68 - 53 = 15

s = 15

Therefore, s is equal to 15

Hope this helps! Have a good rest of your day!

Answer:

15

Step-by-step explanation:

This is very simple, first we write the equation, s+53=g, and plug 68 into "g", so now we have s+53=68. Subtract both sides, s+53-53=68-53, and this equals 15 years of age

Answer:

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

Given

[tex]11^{x}[/tex] = [tex]11^{4}[/tex] × [tex]11^{5}[/tex] = [tex]11^{(4+5)}[/tex] = [tex]11^{9}[/tex]

Since the bases on both sides are common, then equate the exponents

Step-by-step explanation:

I believe it's a scalene triangle.

We could mark that ME = d, where d= diamater.

For segment TE, we can tell it is different length then all of the other lines.

Now, would MT be equivalent to ME in length? No. I can tell that segment MT is a tiny bit shorter than ME.

Why? If we look at line TE, we can tell that it is not perfectly horizontal; it is slanted to the left. By logic, we can deduce that because the left slant brings T ever so closely to M, there is a shorter distance between M and T than M and E.

If none of the sides are the same length, the triangle is scalene.

If you are able, I'd really appreciate a rating, or if you have questions, I'd be happy to answer.

Answer:

8 units

Step-by-step explanation:

If the area of the squares are 32 units^2, we have that:

Area = Side * Side

Side^2 = 32

Side = sqrt(32) = 5.657 units

So as the squares are adjacent to two sides of the triangle, we have that the triangle has two sides of 5.657 units

As it is a right triangle, we can use the Pythagoras' theorem:

c^2 = a^2 + b^2

c^2 = 5.657^2 + 5.657^2

c^2 = 64

c = 8 units

Answer:

[tex] \boxed{Volume \: of \: rectangular \: prism = 2166 \: {ft}^{3}} [/tex]

Explanation:

Volume of rectangular prism is same as volume of cuboid

Length = 19 ft

Width = 6 ft

Height = 19 ft

Volume of rectangular prism = Length × Width × Height

= 19 × 19 × 6

= 19² × 6

= 361 × 6

= 2166 ft³
