Step-by-step explanation:

The slope-intercept equation of a line that passes through the points (-2,5) and (6,-4) is [tex]y=-\frac{9}{8}x+\frac{11}{4}[/tex]

We know that the slope-intercept form of the line is y =  mx + c, where m is the slope of the line and c is the y-intercept of the line.

For given question we have been given two points (-2,5) and (6,-4)

We need to find the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4).

Using two-point form the equation of the line is,

[tex]\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1}[/tex]

Let (x1, y1) = (-2,5) and (x2, y2) = (6,-4)

So, the equation of the line is,

[tex]\frac{y-5}{-4-5} =\frac{x-(-2)}{6-(-2)}\\\\ \frac{y-5}{-9} =\frac{x+2}{6+2}\\\\\frac{y-5}{-9} =\frac{x+2}{8}\\\\ 8(y-5)=-9(x+2)\\\\8y-40=-9x-18\\\\8y=-9x-18+40\\\\8y=-9x+22\\\\y=-\frac{9}{8}x+\frac{11}{4}[/tex]

above equation is in the slope-intercept form.

Therefore, the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4) is [tex]y=-\frac{9}{8}x+\frac{11}{4}[/tex]

The simplified form of the expression 8 + (-7)² - (7 × (-2) + 1 ) is 70.

Given the expression in the question;

8 + (-7)² - (7 × (-2) + 1 )

Simplify each term, raise -7 to the power 2

8 + (-7)² - (7 × (-2) + 1 )

8 + 49 - (7 × (-2) + 1 )

Multiply 7 by -2

8 + 49 - ( -14 + 1 )

Add -14 and 1

8 + 49 - ( -13)

Remove parenthesis by multiplying -1 by -13

8 + 49 + 13

Now, simplify by adding the number

8 + 49 + 13

57 + 13

70

Therefore, the simplified form of the expression 8 + (-7)² - (7 × (-2) + 1 ) is 70.

3 Answers: Choice A, Choice B, Choice E

=========================================================

Explanation:

We have four copies of x in the original expression. So that accounts for the 4x. In other words, 4x = x+x+x+x. Multiplication is used for repeated addition.

Also, the other terms add to 15+5+15+5 = 20+20 = 40

Therefore, we end up with 4x+40 from choice A.

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

Once we get to 4x+40, we can factor out 2 from it like so

4x+40

2*2x + 2*20

2(2x+20) which is choice B

I used the distributive property to factor. That rule is a(b+c) = ab + ac

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

Choice C is not one of the answers. We can determine this fairly quickly by noting that the expression in choice C talks about a quadratic, but the original expression given to us is linear.

Choice D is a similar story to choice C.

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

Choice E is another answer

This is because we have two copies of (x+15), so that gives 2(x+15)

We also have two copies of (x+5) to get 2(x+5)

Answer:

Step-by-step explanation:

The formula is (2x60)/15=8.

Answer:

[tex]1[/tex] and [tex]6[/tex].

Step-by-step explanation:

Let [tex]x[/tex] denote one of the integers. Since the two integers add up to [tex]7[/tex], the other integer would be [tex](7 - x)[/tex].

The sum of the squares of these integers is [tex]37[/tex]. In other words:

[tex]x^{2} + (7 - x)^{2} = 37[/tex].

Expand [tex](7 - x)^{2}[/tex] using binomial expansion. Simplify and rewrite this equation and solve for [tex]x[/tex].

[tex]2\, x^{2} - 14\, x + 12 = 0[/tex].

[tex]x^{2} - 7\, x + 6 = 0[/tex].

Using the quadratic formula or factorization, [tex]x = 1[/tex] or [tex]x = 6[/tex]. Thus, the two integers are [tex]1[/tex] and [tex]6[/tex].

    a) Gas has a volume of 12 liters.

    b) 12 liters of oxygen gas will be consumed during the reaction.

Step-by-step explanation:

Moles of Substances:

We measure the quantity of atoms and molecules in moles, which is equal to 6.022 ×10²³, Avogadro's number, because they are too small to be counted or weighed individually. A substance's atomic mass is multiplied by Avogadro's number to get its mass in grams.

Here, Half a mole of carbon is equal to six grams of carbon. since 12 grams make up one mole of carbon. Since carbon dioxide has the chemical formula CO2, when a mole of carbon is fully combusted, it will result in the production of a mole of carbon dioxide gas.

a) Half a mole of gas has a volume of 12 liters because one mole of gas at RTP consumes 24 liters.

b) Due to the fact that each oxygen molecule contains two oxygen atoms and each carbon dioxide molecule contains two oxygen atoms, 12 liters of oxygen gas will be consumed during the reaction.

The probability of selecting both defective gadgets out of 100 gadgets is 1/110, which is calculated using the basic concepts of probability theory.

What is a random experiment?

An experiment that is repeated several times and produces more than one possible outcome is called as the random experiment. It contains a well-defined set of values which constitutes a sample space. Eg: Rolling a die, tossing a coin etc.

Calculation of the probability of selecting both gadgets as defective

The total amount of gadgets = 100

Number of defective gadgets = 10

The probability of selecting a defective gadget is 10 / 100 or 1 / 10

Now, the total number of gadgets and defective gadgets are decreased by 1

So, the probability of selecting another gadget as defective is 9 / 99 or 1 / 11

P(E) = P(when two selected gadgets are defective) = 1 / 10 x 1 / 11

P(E) = 1 / 110

Hence, the probability of selecting both defective gadgets is 1/110.

Answer:

One line of intersection (three points of intersection)

Answer:

Below.

Step-by-step explanation:

a. True - it states that 4 is an element of Set P.

b False - 5 is an element of set Q .

   5 ∈ Q.

c. P ∩ Q = Ф True - This says that there are no common elements in P and Q   which is true.  Ф is the 'empty set'.

d. True: n(P) = 4 means there are 4 elements in P.

e. True: there are 4 elements in P and in S.

   S can be written as {3, 4, 5, 6} - that is the integers which are greater      than 2 and less than or equal to 6. The Z means the set of integers.
