Step-by-step explanation:

A linear expression has the highest power of the variable to 1, i.e ax+b

Then only the first option is in a linear expression format

9x-2

The linear expression from the given options is 9x - 2.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given are four expressions consisting of variable x.

Linear expressions are those expressions for which the highest degree of the variable in the expression is 1.

Look at the expressions with the power of the variable equals one and no other term in the expression has power of the variable more than 1.

The expression is 9x - 2.

In 3x² + 4x - 5, the highest degree of the variable is 2.

In 5x³ + 6x² - 7x + 8, highest degree of the variable is 3.

In 4x⁴ - 5x³ + 6x² - 7x + 8, highest degree of the variable is 4.

Hence the linear expression is 9x - 2.

Answer:

21 feet (20.977)

Step-by-step explanation:

1. Draw a picture, it makes it much easier. Draw a right triangle with the vertical labeled 25 and the horizontal labeled X, then label the angle adjacent to the horizontal and hypotenuse 40°

2. Use tangent because X is opposite of 40 and 25 is adjacent to angle 40. the equation would be Tan40/1 = X/25

3. You then cross multiply to get 25Tan(40) = X

4 You then plug it into a calculator and get the full answer of 20.97749078, but I always round up to either 20.98 or 21 feet, whatever your teacher allows

Answer:

mean = -0.25

Step-by-step explanation:

Explanation:-

mean:- The sum of all the observations and then divided the number of observations and it is denoted by 'μ'

given data is -15 , -12 , 8 and 9

Given observations is '4' so n = 4

[tex]mean= \frac{-15-12+8+9 }{4}[/tex]

[tex]mean= \frac{-27+17}{4}[/tex]

[tex]mean = -0.25[/tex]

The mean of given data is - 0.25

The mean of -15, -12, 8, and 9 is calculated by summing the numbers to get -10 and then dividing by 4, leading to a mean of -2.5.

The mean of a set of numbers is calculated by summing up all the numbers and then dividing the total by the count of the numbers. In this case, to find the mean of -15, -12, 8, and 9, you would add these four numbers together and then divide by 4, because there are four numbers in this set.

The calculation would look like this:

(-15) + (-12) + 8 + 9 = -10

To find the mean, you would then divide -10 by the number of values in the set, which is 4:

Mean = -10 / 4 = -2.5

Therefore, the mean of the numbers -15, -12, 8, and 9 is -2.5.

Final answer:

Pedro had 1,482 hits, while Ricky had 1,204 hits. We determined these numbers by setting up a system of linear equations and solving for both players' hits using substitution.

Explanation:

To solve the problem of determining how many base hits teammates Pedro and Ricky had last season, we can set up a system of linear equations. Let's let P represent the number of hits Pedro had, and R represent the number of hits Ricky had. According to the problem, together they had 2,686 hits, so we can write the first equation as:

P + R = 2,686

The second piece of information tells us that Pedro had 278 more hits than Ricky, which gives us the second equation:

P = R + 278

We can substitute the second equation into the first equation to find the value of R:

P = (R + 278)

(R + 278) + R = 2,686

2R + 278 = 2,686

2R = 2,686 - 278

2R = 2,408

R = 1,204

Now, we know Ricky had 1,204 hits. To find out how many hits Pedro had, we substitute R's value back into the second equation:

P = 1,204 + 278

P = 1,482

So, Pedro had 1,482 hits and Ricky had 1,204 hits.

Answer: 9.84 x 10²

Step-by-step explanation: To write 984 in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.

So here we have 9.84.

Next, count the number of places that we would need to move the decimal point in 9.84 in order to get back to the original number, 984.

Since we would need to move the decimal point two places to the right to get back to the original number, we have an exponent of 2.

Notice that our exponent is positive because we would need to move the decimal point to the right.

Now, scientific notation is always expressed as a power of 10. In this case, we have 10 to the 2nd or 10 to the 2nd power.

So 984 can be written in scientific notation as 9.84 x 10².

The width of the canyon is 315 ft.

An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

Given that, Jim owns a restaurant on the edge of a canyon. He wants to install a cable car over the canyon. He needs to know the width of the canyon. (please refer to the figure attached)

m ∠ ABC = 180°-80°  (Linear pair)

m ∠ ABC = 100°

In Δ ABC,

∠ A + ∠ B + ∠ C = 180°  (sum of interior angles of a triangle)

∠ A = 180°-(100°+40°)

∠ A = 40°

Since, ∠ A = 40° and ∠ C = 40°

Therefore, ∠ A = ∠ C

Therefore, AB = BC (Side opposite to equal angles are equal)

That means,  Δ ABC is an isosceles triangle

∵ BC = 315 ft

∴ AB = 315 ft

AB is the width of the canyon.

Hence, The width of the canyon is 315 ft.

Maggie wants to the middle of the healthy range weight 130lbs should she gain.

Given that,

Maggie weighs for her height = 105lbs

Recommended weight = 120lbs

Limit for weighs not more than = 160lbs

We have to find ;

If she wanted to be in the middle of the healthy range how much weight should she gain.

Answer:

A) 200

Step-by-step explanation:

x = 6600/33

x = 200

x = 5

Solution:

Given equation is [tex]x+1=\sqrt{5x+11}[/tex].

[tex]\Rightarrow x+1=\sqrt{5x+11}[/tex]

Squaring on both sides of the equation to remove the square root.

[tex]\Rightarrow (x+1)^2=(\sqrt{5x+11})^2[/tex]

[tex]\Rightarrow (x+1)^2=5x+11[/tex]

Using algebraic identity: [tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex]\Rightarrow x^2+2x(1)+1^2=5x+11[/tex]

[tex]\Rightarrow x^2+2x+1=5x+11[/tex]

Combine all terms in one side of the equation.

[tex]\Rightarrow x^2+2x+1-5x-11=0[/tex]

Arrange like terms together.

[tex]\Rightarrow x^2+2x-5x+1-11=0[/tex]

[tex]\Rightarrow x^2-3x-10=0[/tex]

Now solve by factorization.

[tex]\Rightarrow x^2-5x+2x-10=0[/tex]

[tex]\Rightarrow (x^2-5x)+(2x-10)=0[/tex]

Take common terms on left side of the term.

[tex]\Rightarrow x(x-5)+2(x-5)=0[/tex]

Now, take (x – 5) common on both terms.

[tex]\Rightarrow (x+2)(x-5)=0[/tex]

⇒ x + 2 = 0 (or) x – 5 = 0

⇒ x = –2 (or) x = 5

If we put x = –2 in the given equation,

[tex]-2+1=\sqrt{5(-2)+11}[/tex]

[tex]\Rightarrow-1=1[/tex]

It is false. So, x = –2 is not true.

If we put x = 5 in the given equation,

[tex]5+1=\sqrt{5\times5+11}[/tex]

[tex]5+1=\sqrt{36}[/tex]

[tex]\Rightarrow6=6[/tex]

It is true. So, x = 5 is true.

Hence x = 5 is the solution.

The simplified fraction is 9/40.

To simplify the complex fraction 1/4 over 10/9, you can multiply both the numerator and the denominator by the reciprocal of the denominator of the complex fraction, which is 9/10. This is sometimes referred to as the skillfully chosen factor. By doing so, you are simplifying the expression by getting rid of the complex fraction structure.

Here's the step-by-step simplification:

Multiply both the numerator (1/4) and the denominator (10/9) by 9/10.

Simplifying the numerator: (1/4) * (9/10) = 9/40.

Simplifying the denominator: (10/9) * (9/10) = 1 because the nines and tens cancel out.

Now you have a simple fraction: 9/40 over 1, which is just 9/40.

The simplified fraction is 9/40. When multiplying fractions, you multiply the top numbers and divide by the bottom numbers in the fractions.

DE and XY are perpendicular.

XAE and DAY are vertical angles.

Step-by-step explanation:

This answer explains the mathematical concepts related to angles and lines i.e., vertical angles, perpendicular lines, complementary angles, and linear pair. Vertical angles are equivalent, perpendicular lines intersect at right angles, complementary angles sum to 90 degrees, and a linear pair of angles sum to 180 degrees.

Without the actual diagram presented in your question, I can only provide some general insights into your question which is related to angles and lines. Firstly, vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Secondly, two lines are perpendicular if they intersect at a right angle(90 degrees). In terms of angles, two angles are complementary when they add up to 90 degrees. Finally, a linear pair refers to two angles that are adjacent (share a common vertex and side but have no common interior points) and whose non-common sides are opposite rays, i.e., they add up to 180 degrees.
