Answer:

V=3x+6

Step-by-step explanation:

slope intercept form: y=mx+b

V-5=3(x+1)

[open parentheses]

V-5=3x+1

[combine like terms; add 5 to both sides]

V=3x+6

We have two equations :

Take the value of x in Equation 2 and substitute in Equation 1.

Now, take the value of y and substitute in Equation 2.

Solution

Answer:

The lines intersect at the point (-1, 0)

Step-by-step explanation:

−5(      )−y=5

-5(7y-1) - y = 5    substitute the x=7y-1 into first equation

-35y + 5 - y =5   multiply -5

-36y + 5 = 5        combine like terms

-36y = 0              subtract 5

y=0                      divide by -36

x=7(0)-1                substitute 0 for y in x=7(  )-1

  =-1                      simplify

The lines intersect at the point (-1, 0)

Step-by-step explanation:

Each point has been moved 2 spaces to the right and 5 units down.

Moving 2 spots to the right means x updates to x+2

Moving 5 units down tells us to change y to y-5

Therefore, [tex](x,y) \to (x+2, y-5)[/tex]

Using the exponential distribution, it is found that there is a 0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The probability that x is lower or equal to a is given by:

[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]

Which has the following solution:

[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]

In this problem, the mean and the decay parameter are, respectively, given by:

[tex]m = 50, \mu = \frac{1}{50} = 0.02[/tex].

The probability that a randomly selected part will fail in less than 20 hours is given by:

[tex]P(X \leq 20) = 1 - e^{-0.02 \times 20} = 0.3297[/tex]

0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.

13× 1/3=4.33

therefore she was able to bike 4.33 miles in 20 minutes at a constant speed

The final step of the inequality equation –10 + 8x < 6x – 4 is x > 3. Then the correct option is D.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

The inequality equation is given below.

–10 + 8x < 6x – 4

This can be simplified as

–10 + 8x < 6x – 4

       –10 < –2x – 4

        –6 < –2x

        –3 < –x

Step-by-step explanation:

5 to 4 equals 9

divide 234 by 9 and you get 26

26 times 5 is 130

and 26 times 4 is 104

so 130 to 104 adding up gives you 234

When multiplying fractions, there is no need to make the denominators the same like how you do when adding fractions

So we can just straight multiply the numerators and the denominators together

[tex]\frac{1}{4}*\frac{3}{1}[/tex]

I made 3 to 3/1 so the multiplying process is easier

3 x 1 is 3 and 4 x 1 is 4

The numerator is 3

The denominator is 4

3/4

So 1/4 x 3 is 3/4

Answer:

8

Step-by-step explanation:

We know that

Equation

[tex] {x}^{2} + {y}^{2} + 2gx + 2fy + c = 0[/tex]

Represents the equation of Circle

where

[tex]radius = \sqrt{ {g}^{2} + {f}^{2} - c } [/tex]

On comparing the given equation with general Equation of Circle

we get

[tex]g = - 5[/tex]

[tex]f = 3[/tex]

[tex]c = - 30[/tex]

On substituting these values We get

[tex]radius = \sqrt{ { (- 5)}^{2} + {3}^{2} - ( - 30) } [/tex]

[tex]radius = \sqrt{25 + 9 + 30 } = \sqrt{64 } = 8[/tex]

[tex]radius = 8[/tex]

This solution is arrived at using the principles of Quadratic Functions and Inequalities. It is to be noted that the function increases at (-8, 4).

A quadratic function can be defined as that is written in the following way: f(x) = ax2 + bx + c: Where a, b, and c are numbers not equal to zero.

To solve the problem f(4x - 3) ≥ f(2 - x^2), Df = (-8 , 4), we:

A) 4x - 3 ≥ 2 - x²

Rewrite as:  x² + 4x - 2 - 3 ≥ 0

B) Collect the like terms

x² + 4x - 5 ≥ 0

C) Expand to have  x² + 5x - x - 5 ≥ 0

D) Factorizing the expression we have

x(x + 5) - 1(x + 5) ≥ 0, from this we  Factor away x + 5

(x - 1)(x + 5) ≥ 0

E) Solving  for x we obtain: x ≥ 1 or x ≥ -5

This can also be rewritten to read:

-5 ≤ x ≤ 1

Answer: B

Step-by-step explanation:

1/2 8 *7 = 28

because there is 4 triangles you do this 28+28+28+28

28+28+28+28 = 112

The lateral surface area of the pyramid is 112 sq. in.

The correct answer is an option (B)

From the attached figure of the net of a square pyramid, we can observe that the side length of the square base is 8 in and height of the lateral triangular face is 7 in.

Hence, The lateral surface area of the pyramid is equal to the area of the four triangular faces of the pyramid.

Using the formula of the area of triangle, the lateral surface area would be,

A = 4 × (1/2 × base × height)

A = 4 × (1/2 × 8 × 7)

A = 4 × (4 × 7)

A = 4 × 28

A = 112 sq. in.

Thus, This is the required lateral surface area.

So, The correct answer is an option (B) 112 in²

Probability helps us to know the chances of an event occurring. The probability of getting a tail and an even number is 0.25.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Since a coin has two faces, therefore, the probability of getting either of the sides of the coin is (1/2). While a die has six faces, so the probability of getting any side of the die is (1/6).

A.) The probability of getting a tail and an even number can be written as,

[tex]\text{Probability of getting a tail} = \dfrac{1}{2}[/tex]

[tex]\text{Probability of Even Number(2,4,6) } = \dfrac{3}{6} = \dfrac{1}{2}[/tex]

[tex]\text{Probability (Tails and an even number)} = \dfrac12 \times \dfrac12 = 0.25[/tex]

B.) The Probability of getting tails and the number 9 can be written as,

[tex]\text{Probability of getting a tail} = \dfrac{1}{2}[/tex]

[tex]\text{Probability of Number 9} = \dfrac{0}{6} = 0[/tex]

[tex]\text{Probability of the tails and the number 9} = 0[/tex]

C.) The Probability of getting Heads or a number bigger than 4 can be written as,

[tex]\text{Probability of getting a Head} = \dfrac{1}{2}[/tex]

[tex]\text{Probability of a number bigger than 4 (5,6) } = \dfrac{2}{6} = \dfrac{1}{3}[/tex]

[tex]\text{Probability (Heads or a number bigger than 4 )} = \dfrac12 + \dfrac13 = \dfrac{5}{6} = 0.83333[/tex]

D.) The Probability of getting Heads or the number 2 can be written as,

[tex]\text{Probability of getting a Head} = \dfrac{1}{2}[/tex]

[tex]\text{Probability of the number 2} = \dfrac{1}{6}[/tex]

[tex]\text{Probability (Heads or the number 2 )} = \dfrac12 + \dfrac16 = \dfrac{8}{12} = 0.6666[/tex]
