y= x²

if x= 9 substitute x with 9 in the equation

y= 9² = 81

Answer:

(x + 7) (x + 7)

Step-by-step explanation:

What's the square root of x^2?

That's x

What's the square root of 49

That's 7

And what makes 14?

7 + 7 = 14

So therefore the answer is (x + 7) (x + 7)

Easy Kevin Durant is so smart!

Answer:

The middle number is 14 and the last number is 49.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 14

Multiply together to get 49

Can you think of the two numbers?

Try 7 and 7:

7+7 = 14

7*7 = 49

Fill in the blanks in

(x+_)(x+_)

with 7 and 7 to get...

(x+7)(x+7)

Answer:

(x+7)(x+7)

Answer:

D) 121 degrees

Step-by-step explanation:

A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.

In this case, since supplementary angles add up to 180 degrees, we set up an equation:

<A+<B=180

(6x-19)+(11x-22)=180

17x-41=180

17x=221

x=13

Now we plug in x=13 for angle B:

11x-22

11(13)-22

143-22

121

Therefore, the measure of angle B is 121 degrees

Answer:

This can be simplified by first checking the operational signs present in the question and the rule goes BODMAS so you add before you subtract so 32+8 = 40-2= 38 thank you

According to the given statement Andrea have to mark 440 yards out of 1760 for her race course.

A yard (yd) is a length unit used in various different systems, including US customary measures, Imperial units, and historic English units. It is 3 feet, 36 inches, or 0.9144 meters.

A conversion factor seems to be a number that can be used to multiply and otherwise divide one set of units by another set of units. The right conversion factor must be used when converting to something like an equivalent value. For example, to convert inches to feet, the appropriate conversion value equals 12 inches equals 1 foot.

Want  quarter-mile course for a race.

Total yards  she has is a = 1760

We know that:

1 mile =  1760 yards

quarter-mile (.25) which means = 1760/4

                                                    = 440 yards

According to the given statement Andrea have to mark 440 yards out of 1760 for her race course.

The following function height_range in python language will accept a list of integers and return the difference between the tallest and shortest height.

Python is a well-liked computer programming language used to build websites and software, automate procedures, and conduct data analysis. Since Python is a general-purpose language, it may be used to create a wide range of applications and isn't specifically designed to address any particular problems. Because of its high-level built-in data structures, dynamic typing, and dynamic binding, it is appropriate for Rapid Application Development as well as for use as a scripting or glue language to connect existing components.

Given that, the Function should accept a list of integers as arguments, and the return type should be an integer value which is the difference between the maximum and minimum element from the list function will be:

Answer:

[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]

Thus, -2 comes under the interval domain of the inequality (-∞, 3].

Hence, (-2, 6) is a solution to the linear inequality.

Step-by-step explanation:

Given the linear inequality

x ≤ 3

substitute the value of x = -2

-2  ≤ 3

TRUE

It is clear that -2 is indeed less than 3. Thus, the ordered pair (-2, 6) is a solution to the linear inequality.

Also,

[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]

Thus, -2 comes under the interval domain of the inequality (-∞, 3].

Hence, (-2, 6) is a solution to the linear inequality.

Answer:

The image of P(11,-4) will be: P'(-6, -2)

Step-by-step explanation:

Given the point

The rule:

(x, y) = (x– 17, y+2)

Meaning the image of P(11,-4) can be determined by subtracting 17 units (moving left) from the x-values and adding 2 units (moving up) to the y-values.

Therefore,

P(11, -4) → P'(11-17, -4+2) = P'(-6, -2)

Thus, the image of P(11,-4) will be: P'(-6, -2)

Answer:

we know that

log (P/N) = log P - log N

so

log P - log N = 5----------------> equation 1

log (M/N) = log M - log N  

so

log M - log N = 9 ------------------> equation 2  

If you subtract equation 2 from equation 1,

you have

log M - log P = 4  

That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P

the answer is

the relationship between P and M is  

M = 10000P

The correct answer is City D.

Step-by-step explanation:

When you say the phrase, "closer to sea level" you mean the closest to the very top of the sea, like "0" on a number line.

This means, that whether it is to the left of the right of the number line (or above or below the sea) whichever one has the lowest absolute value is the closest.

Therefore, the correct answer is City D.

Step-by-step explanation:

Diameters of the belt produced are given in fractions which can be converted to decimals to know their values.

Thus,

1 3/2 in. = [tex]\frac{5}{2}[/tex] in. = 2.5 in.

7/16 in. = 0.4375 in.

3/4 in. = 0.75 in.

5/8 in. = 0.625 in.

1 5/16 in. = [tex]\frac{21}{16}[/tex] in. = 1.3125 in.

Arranging the vales from least to greatest, we have;

0.4375 in., 0.625 in.,0.75 in., 1.3125 in., 2.5 in.  = [tex]\frac{7}{16}[/tex] in., [tex]\frac{5}{8}[/tex] in., [tex]\frac{3}{4}[/tex] in., 1[tex]\frac{5}{16}[/tex] in., 1[tex]\frac{3}{2}[/tex] in.

Answer:

confused on what you are asking

Step-by-step explanation:

The option b and c is correct.

To solve this problem we must be aware of the concepts of line segment. And also what is a mid point.

When we connect two dots or two points it forms a line segment or we can say that line segment is part of line which is bounded by two points.

Mid-point of any line or line segment is that point which divides the line segment into two equal parts and also a point which is equidistant from the two endpoints.

So, a midpoint of a line segment divides the line segment in two equal parts and is also equidistant from the two endpoints.

Here, the appropriate option is b and c.
