Answer:

Slope intercept form: y = -x + 5

Point slope form: y - 4 = -1 (x - 1)

Step-by-step explanation:

First we need to find slope by using this formula⤵⤵⤵

[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]

(Sorry if it's a bit small btw)

-1 - 4 = -5

6 - 1 = 5

Simplify -5/5 by dividing, and your slope is -1.

Now we plug in one of the points and the slope into the point slope formula⤵⤵⤵

[tex]y - y _{1} = m(x - x _{1})[/tex]

We'll use point (1,4) for this:

y - 4 = -1 (x - 1)

To solve this, start by distributing the -1 among everything inside the parenthesis to get

y - 4 = -x + 1. Next, add 4 on both sides to get

y = - x + 5.

Hope this helps you :)

Step-by-step explanation:

Decrease % = 4.2% = 0.042

Total area = 1500 km²

[tex]y =(1 -0.042)^{t}*1500\\\\y= 1500*(0.958)^{t}[/tex]

The interest that will be paid in 10 years is = $2,925

The total amount of money deposited as savings (p)

= $4,500,

The annual simple interest rate (r) = 6.5%.

The time to collect the interest expected (t) = 10 years.

There the simple interest generated =

[tex] \frac{p \times t \times r}{100} [/tex]

[tex] \frac{4500 \times 10 \times 6.5}{100} [/tex]

[tex] \frac{292500}{100} [/tex]

Therefore simple interest = $2,925

7. Theorem : When a transversal cuts two lines, such that pairs of corresponding angles are equal, then the lines have to be parallel.

8. Postulate : When a transversal cuts two lines, such that pairs of alternate interior angles are equal, the lines have to be parallel.

Good Luck

Answer:

1 is parallel to 3. 1 is perpendicular to 2. 2 is perpendicular to 3.

Step-by-step explanation:

The slope of line 1 is 5/3. This is because it is the m term from the equation y=mx+b.

The slope of line 2 is -3/5. You would have to solve the equation in the following format.

[tex]6x+10y-6x=-4-6x[/tex]

[tex]\frac{10y}{10}=\frac{-4-6x}{10}[/tex]

Which simplifies to y=-2/5 - 3/5x, making -3/5 the slope.

The slope of line 3 is 5/3, which can be found by dividing both sides of the equation by 3.

Parallel lines have exactly the same slope. So lines 1 and 3 are parallel.

Perpendicular lines have opposite reciprocal slopes. So lines 1 and 2, and 2 and 3 are both perpendicular.

Answer:

-21

28

Step-by-step explanation:

1) if r = -4

Substitute r = -4 in 3r - 9

= 3 * (-4) - 9

= -12 - 9

= -21

2) ( 4 / 7 ) * x = 16

 4 * x = 16 * 7

 x = 4 * 7

 x = 28

Testing the hypothesis, it is found that:

a)

The null hypothesis is: [tex]H_0: \mu \leq 10[/tex]

The alternative hypothesis is: [tex]H_1: \mu > 10[/tex]

b)

The critical value is: [tex]t_c = 1.74[/tex]

The decision rule is:

c)

Since t = 1.41 < 1.74, we do not reject the null hypothesis, that is, it cannot be concluded that the mean weight loss is of more than 10 pounds.

Item a:

At the null hypothesis, it is tested if the mean loss is of at most 10 pounds, that is:

[tex]H_0: \mu \leq 10[/tex]

At the alternative hypothesis, it is tested if the mean loss is of more than 10 pounds, that is:

[tex]H_1: \mu > 10[/tex]

Item b:

We are having a right-tailed test, as we are testing if the mean is more than a value, with a significance level of 0.05 and 18 - 1 = 17 df.

Hence, using a calculator for the t-distribution, the critical value is: [tex]t_c = 1.74[/tex].

Hence, the decision rule is:

Item c:

We have the standard deviation for the sample, hence the t-distribution is used. The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

For this problem, we have that:

[tex]\overline{x} = 10.8, \mu = 10, s = 2.4, n = 18[/tex]

Thus, the value of the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{10.8 - 10}{\frac{2.4}{\sqrt{18}}}[/tex]

[tex]t = 1.41[/tex]

Since t = 1.41 < 1.74, we do not reject the null hypothesis, that is, it cannot be concluded that the mean weight loss is of more than 10 pounds.

Answer:

$20.55

Explanation:

The total amount spent on apples is $20.5425.

Given that, Kathy is baking 3 apple pies. Each pie requires 2 3/4 pounds of apples. Apples cost $2.49 a pound.

We need to find out how much will Kathy spend on apples.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the amount spent on apples be x.

Now, 2 3/4=11/4

The total number of apples required to make 3 apple pies=3 × 11/4

=33/4 pounds

Apples cost $2.49 a pound.

So, the amount spent on apples=x=33/4 × 2.49

=$20.5425

Therefore, the total amount spent on apples is $20.5425.

Answer:

(x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.

Step-by-step explanation:

Factor the numerator:

(x+9)(x-5)

Factor the denominator:

(x+1)(x+9)

So you have

(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?

You're left with (x-5)/(x+1)

The only number that is restricted is -1, because that would make the denominator zero, which is a no no

Answer:

Step-by-step explanation:

To avoid ambiguity please write the given expression as  

                                                                 x² + 4x - 45

x² + 4x - 45/(x^2+10x+9) or (better) as ---------------------

                                                                   x^2+10x+9

Notice that both numerator and denominator have the factor x + 9:

 (x + 9)(x - 5)

---------------------

 (x + 9)(x + 1)

This allows us to cancel out the (x + 9) factor, resulting in:

x - 5

------- ONLY for x ≠ -1 and x = -9

x + 1

We must exclude these two x-values because otherwise the denominator would be zero, which is not allowed.

16y − 8 is your answer!

Step-by-step explanation:

Simplify the expression!

Using conditional probability, it is found that there is a 0.6262 = 62.62% probability that the part is indeed defective.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

In this problem:

Event A: Positive test result.

Event B: Defective.

For the probability of a positive test result, we consider two scenarios.

Hence:

[tex]P(A) = 0.995(0.01) + 0.006(0.99) = 0.01589[/tex]

The probability of a positive test result and being defective is:

[tex]P(A \cap B) = 0.995(0.01)[/tex]

The conditional probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.995(0.01)}{0.01589} = 0.6262[/tex]

0.6262 = 62.62% probability that the part is indeed defective.

Answer:

Step-by-step explanation:

x distance from A to B

6 - (-2) = 8

3/5(8) = 24/5 = 4.8             or        2/5(8) = 16/5 = 3.2

-2 + 4.8 = 2.8                                 6 - 3.2 = 2.8

y distance from A to B

1 - (-4) = 5

3/5(5) = 3                           or        2/5(5) = 2

-4 + 3 = -1                                       1 - 2 = -1

P = (2.8, -1)

The coordinates of point P (rounded to one decimal place) along the directed line segment AB are approximately (2.8, -1).

Given that the line segment has been divide into ratio 3:2 by a point P, we need to find the coordinates of the point P.

To find the coordinates of point P along the directed line segment AB, such that the ratio of AP to PB is 3 to 2, we can use the concept of section formula in coordinate geometry.

Let's assume the coordinates of point P are (x, y). According to the given information, the ratio of AP to PB is 3 to 2. This means that the distance between A and P (AP) is three times the distance between P and B (PB).

The section formula states that if a point P(x, y) divides the line segment joining points A(x₁, y₁) and B(x₂, y₂) in the ratio m:n, then the coordinates of point P can be calculated as:

x = (mx₂ + nx₁) / (m + n)

y = (my₂ + ny₁) / (m + n)

In this case, m = 3 and n = 2.

Coordinates of A: (x₁, y₁) = (-2, -4)

Coordinates of B: (x₂, y₂) = (6, 1)

Ratio m:n = 3:2

Now, let's plug the values into the section formula to find the coordinates of P:

x = (3 · 6 + 2 · (-2)) / (3 + 2)

= (18 - 4) / 5

= 14 / 5

= 2.8

y = (3 · 1 + 2 · (-4)) / (3 + 2)

= (3 - 8) / 5

= -5 / 5

= -1

So, the coordinates of point P is (2.8, -1).
