Answer:

slope of line 1

m = (-8 - 2) / (2 + 2)

m = -10/4 = -5/2

slope of line 2

m = (6 + 1) /(5 - 0)

m = 7/5

slope of line 3

m = (-2 + 7) /(2 - 4)

m = 5/ -2

m = -5/2

Line 1 and Line 2 are neither.

Line 1 and Line 3 are parallel since they have same slope.

Line 2 and Line 3 are neither.

If x 2 = x, then x = 1 true or false?

Answers

Answer:

False

Step-by-step explanation:

If x * 2 = x, and you use 1 as the insert for x, then you would be saying that 1 * 2 = 1, and that is incorrect.

Answer:

I assume the value is x² right from the qn.

With that

x² = x

if x = 1

then

1² = 1

hence the value is true.

To solve the equation, factor a  

2

−13a+42 using formula a  

2

+(a+b)a+ab=(a+a)(a+b). To find a and b, set up a system to be solved.

a+b=−13

ab=42

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 42.

−1,−42

−2,−21

−3,−14

−6,−7

Calculate the sum for each pair.

−1−42=−43

−2−21=−23

−3−14=−17

−6−7=−13

The solution is the pair that gives sum −13.

a=−7

b=−6

Rewrite factored expression (a+a)(a+b) using the obtained values.

(a−7)(a−6)

To find equation solutions, solve a−7=0 and a−6=0.

a=7

a=6

The price p in dollars and the quantity x sold of a certain product obey the demand equation -1/5x+100 (0≤ x ≤ 500)
a) Express the revenue R as a function of x. (remember, R= p.x)

b) What is the revenue if 200 units are sold?

c) What quantity x that maximizes the revenue?

e) What price should the company charge to maximize revenue?

Answers

Answer:

See below

Step-by-step explanation:

We have:

p = -1/5x + 100 = -0.2x + 100

a) The revenue is:

R = px R = x( -0.2x + 100)R= -0.2x² + 100x

b) x = 200, find R:

R = -0.2(200²) + 100(200) = 12000

c) This is a quadratic function and the maximum value is obtained at vertex.

x = -100/(-0.2*2) = 250 is the required quantity

d) The max revenue is obtained when -0.2x + 100 at max:

The maximum possible is p = 100 when x = 0

3.) The quotient property is applied: if two same bases divide with exponent values, then the exponents subtract, and the bases remain. Therefore, n^5 / n^3 = n^5-3 = n^2.

4.)The same rule is applied to this one because the bases (q) are the same variable, and the operation is division. q^2 / q^4 = q^2-4 = q^-2.
Now, we have a negative exponent, here’s what to do:
With a negative exponent, we picture a 1 under the q^-2, like this: q^-2 / 1. We can’t have a negative exponent. So, to get it of positive value, we move it down to where the 1 is. We then get: 1/q^2. We simply shifted it from the numerator to the denominator which cancels out the negative. Your answer is 1/q^2.

5.) 4^5 / 4^4 = 4^5-4 = 4^1 or just 4. This is because of the quotient property.

6.) (-3)^1 / (-3) ^1 = -3^1-1 = -3^0. Now we have an exponent of zero. Whenever you see an exponent to the value of zero, the whole entire base and exponent just becomes the whole number of 1. Therefore, -3^0 = 1 as your answer.

Can anyone help? This is super difficult.

Answers

Answer:

A

Step-by-step explanation:

Recall that from the Exterior Angle Theorem, the exterior angle is equal to the sum of the two interior angles opposite from the exterior angle.

In other words:

[tex]\displaystyle m\angle QPT = m\angle HQP + m\angle PHQ[/tex]

We are given the expressions of each angle. Substitute:

[tex](6x+20)^\circ = (x+40)^\circ + (4x-5)^\circ[/tex]

Solve for x:

[tex]\displaystyle \begin{aligned} 6x + 20 & = (x+40) + (4x-5) \\ \\ 6x + 20 & = 5x + 35 \\ \\ x & = 15 \end{aligned}[/tex]

Hence, the value of x is 15.

Then the measure of ∠QPT will be:

[tex]\displaystyle\begin{aligned} m\angle QPT & = (6x+20)^\circ \\ \\ & = (6(15)+20)^\circ \\ \\ & = (90 +20)^\circ \\ \\ & = 110^\circ\end{aligned}[/tex]

In conclusion, our answer is A.

A is the correct answer :)

Lin’s job pays$8.25 an hour plus$10 of transportation allowance each week. She has to work at least 5 hours a week to keep the job, and can earn up to $175 per week (including the allowance). 1.Represent this situation mathematically. If you use variables, specify what each one means. 2.How many hours per week can Lin work? Explain or show your reasoning.

Answers

Answer:

20

Step-by-step explanation:

($8.25 x 5 hours) + 10x <= 175

41.25 + 10x <= 175

x =4  that is 4 weeks

so multiple 5 hours by 4 to get 20 hours

that way she is earning 175 per week

The algebraic inequality will be (3x + 4) / 4 > 3. Then the value of x will be greater than 8/3.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

I think of a number.

Let the number be 'x'.

Then I multiply it by 3. Then the expression will be

⇒ 3x

Then I add 4. Then the expression will be

⇒ 3x + 4

Then I divide the answer by 4. Then the expression will be

⇒ (3x + 4) / 4

My final answer is 3 less than the number I thought of at the beginning. Then we have

(3x + 4) / 4 > 3

Simplify the equation, then the value x will be

(3x + 4) / 4 > 3

3x + 4 > 12

3x > 8

x > 8/3

The algebraic inequality will be (3x + 4) / 4 > 3. Then the value of x will be greater than 8/3.
