Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1) \\ [/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-5,-2) and the slope is - 6/5

The equation of the line is

[tex]y + 2 = - \frac{6}{5} (x + 5) \\ y + 2 = - \frac{6}{5} x - 6 \\ y = - \frac{6}{5} x - 6 - 2[/tex]

We have the final answer as

[tex]y = - \frac{6}{5} x - 8 \\ [/tex]

Hope this helps you

Answer: Reflexive Postulate

Any number or expression that is equal to itself is due to the reflexive postulate of equality. Think of a mirror and how it gives a reflection. That's one way to remember. It might seem like a silly idea, but it's useful in geometry settings among other places as well.

Answer:

a. 2³   b. 8

Step-by-step explanation:

(2*2)=2 papers cut in half

2*2*2=2 papers cut in half twice

2*2*2=2³

2³=8

The situation is 1 x 2 + (1 x 2) ³ = X. Kwami has 10 pieces of paper now.

Since Kwami had two large sheets of paper, and he cut each piece of paper in half, and then he cut the smaller pieces of paper in half two more times, to write this as a power and determine how many pieces of paper does Kwami have now the following calculation must be performed:

First, you must consider the division of the paper, and then consider the number of times that process was repeated.

So now Kwami has 10 pieces of paper.

Answer:

39.52 Liters

Step-by-step explanation:

Chris has 10.4 Gallons of gasoline, which needs to be converted into Liters. This is done by multiplying the number of Liters there are in 1 Gallon.

[tex]10.4*3.8=39.52[/tex]

or you can set it up in a fraction and cross multiply to cancel out the units in Gallons

[tex] - 3[/tex]

Answer:

- 3

Step-by-step explanation:

Using the rules of exponents/ radicals

[tex]a^{\frac{m}{n} }[/tex] ⇔ [tex]\sqrt[n]{a^{m} }[/tex]

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]

Thus

[tex]64^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{64}[/tex] = 4

[tex]64^{-\frac{1}{3} }[/tex] = [tex]\frac{1}{4}[/tex]

[tex]64^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{64^{2} }[/tex] = 4² = 16

Substituting values into the given expression

[tex]\frac{1}{4}[/tex] (4 - 16)

Given:

The equation is

[tex](x-2)=-(x-2)[/tex]

Isabel says that the given equation has no  solution because a number can never be equal to its opposite.

To find:

Isabel's mistake.

Solution:

Her reason "a number can never be equal to its opposite" is not correct.

Zero is a number that can be equal to its opposite.

So, the given equation has solution for which LHS=RHS=0.

We have,

[tex](x-2)=-(x-2)[/tex]

[tex]x-2=-(x)-(-2)[/tex]

[tex]x-2=-x+2[/tex]

Add x and 2 on both sides.

[tex]x-2+x+2=-x+2+x+2[/tex]

[tex]2x=4[/tex]

Divide both sides by 2.

[tex]x=\dfrac{4}{2}[/tex]

[tex]x=2[/tex]

So, the given equation has a solution x=2.

We have the two following equation -

[tex]x^{2} +(6x^{2} +5)=5x^{2} -4[/tex]

We have to find out which property justifies Gabrielle's first step.

According to associative property of addition changing the grouping of addends does not change the sum.

For example -  ( 2 + 3 ) + 4 = 2 + ( 3 + 4 )

According to the question, on the left hand side, we have -

[tex]x^{2} +(6x^{2} +5)[/tex]

Using the associative property of Addition, we can write the above expression as -

which equals to :  [tex]7x^{2}[/tex] + 5

Step-by-step explanation:

Answer:

a. Yes.

b. The probability that a household is without kids:

= 0.3167

c. The probability of a household is with kids and owns an Apple product:

= 61%

d. The probability that a household is without kids and does not own an Apple product:

= 52%

Step-by-step explanation:

a) Data and Calculations:

Probability of a household owning an Apple product = 51%

This implies that the probability of a household not owning an Apple product = 49% (100 - 51)%.

Probability of a household with kids owning an Apple product = 61%

This implies that the probability of a household with kids not owning an Apple product = 39% (100 - 61)%.

Probability of a household without kids owning an Apple product = 48%

This also implies that a household without kids not owning an Apple product = 52% (100 - 48)%.

Sample of households = 1,200

Households with kids = 820

Probability of households with kids = 0.6833 (820/1,200)

Therefore, the probability of households without kids = 0.3167 (380/1200)

b) The events "household with kids" and "household without kids" are mutually exclusive and exhaustive because (a) the two events are separate and do not overlap and (b) the two events are inclusive of all possible options.  It is either a household has kids or it does not.  In this situation, no middle ground exists.

Answer: B) Comparison Postulate

This is the idea where if we had two numbers A and B, then we have the three possibilities

We can only pick one item that is true at a time.

In this case, 3+2 simplifies to 5, so 3+2 = 5 is true while 3+2 > 5 is not true.

3+2 > 5 simplifies to 5 > 5, and there's no way a number is larger than itself.

Answer:

a.) transitive property of equality

Step-by-step explanation:

[A] is the sum of the first 998 consecutive positive integers, so it has 998 terms in it.

Gauss's method involved doubling the sum while grouping terms in a clever way: let S be the sum, so that

S = 1 + 2 + 3 + ... + 996 + 997 + 998

It's also true that

S = 998 + 997 + 996 + ... + 3 + 2 + 1

so that adding these equations together gives

2S = (1 + 998) + (2 + 997) + ... + (997 + 2) + (998 + 1)

2S = 999 + 999 + ... + 999 + 999

We know there are 998 terms on the right side, so

2S = 998 * 999 = 997,002

S = 997,002/2 = 498,501

[B] You can do this one the same way. The hardest part is counting how many terms there are in the sum.

Starting with 1, the n-th positive odd integer is given by 2n - 1. The last term in this sum is 101, so

2n - 1 = 101

2n = 102

n = 102/2 = 51

and the sum contains 51 terms.

Let S denote the sum. Then

S = 1 + 3 + 5 + ... + 97 + 99 + 101

S = 101 + 99 + 97 + ... + 5 + 3 + 1

2S = (1 + 101) + (3 + 99) + ... + (99 + 3) + (101 + 1)

2S = 102 + 102 + ... + 102 + 102

2S = 51 * 102 = 5202

S = 5202/2 = 2601

Answer:

2 5/8 cups of flour

Step-by-step explanation:

Use a proportion.

1 3/4 cups of flour is to 2/3 of a batch as x cups of flour is to 1 batch.

1 3/4 : 2/3 = x : 1

2/3 x = 1 3/4 * 1

2/3 x = 1 3/4

2/3 x = 7/4

3/2 * 2/3 x = 3/2 * 7/4

x = 21/8

x = 2 5/8

Inequalities

Is a relation that makes a non-equal comparison between two mathematical expressions using comparators as >, <, ≤, and ≥, among others.

Some usual operations performed in equations cannot be done in the same way in inequalities, especially multiplying or dividing by negative numbers. When we need to multiply or divide by a negative number, the inequality sign must be flipped.

Let's start off with the inequality

4>-3

a) Add 3 to each side:

4+3>-3+3

7>0

b) Subtract 2 from each side:

4-2>-3-2

2>-5

c) Multiply each side by 2:

2*(4)>2*(-3)
