Answer:

a) [tex] \frac{4}{3} [/tex]

b) -1

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

where (x₁, y₁) is the first point and (x₂, y₂) is the second point

6a) Slope

[tex] = \frac{7 - 3}{4 - 1} [/tex]

[tex] = \frac{4}{ 3} [/tex]

6b) Slope

[tex] = \frac{6 - 5}{2 - 3} [/tex]

[tex] = \frac{1}{ - 1} [/tex]

= -1

Answer:

The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.

Answer:

Exponential notation is a powerful way to express repeated

multiplication of the same number. Specifically, powers of 10

express very large and very small numbers in a manner which is

convenient to read, write and compare.

• For any non-zero integer a, a–m 1

m a

=

• Laws of exponents are

(a) am × an = am+n

(b) am ÷ an = am–n

(c) (am)

n = amn

(d) am × bm = (ab)

m

(e) a° = 1, where a ≠ 0

(f)

m m

m

a a

b b

  =   

• Numbers can be expressed in expanded form by using exponents.

• Very large and very small numbers can be expressed in standard

form.

• Standard form is also called scientific notation form.

Step-by-step explanation:

Example 1 : Multiplicative inverse of 27 is

(a) 2–7 (b) 72 (c) – 27 (d) – 27

Solution : The Correct answer is (a).

Example 2 : The human body has about 100 billion cells. This number

can be written in exponential form as

(a) 10–11 (b) 1011 (c) 109 (d) 10–9

Solution : The correct answer is (b).

In examples 3 to 5, fill in the blanks to make the statements true.

Example 3 :

Solution : 54

Example 4 : ( ) ( ) 2 3 –3 –2 2 3 _____ × =

Solution : 6–6

Example 5 : The distance between earth and sun is 150 million

kilometres which can be written in exponential form as

_______.

Solution : 1.5 × 108 km

In examples 6 and 7, state whether the statements are true (T) or false (F):

Example 6 : Very small numbers can be expressed in standard form

using positive exponents.

Solution : False.

Example 7 : (–10) × (–10) × (–10) × (–10) = 10–4

Solution : False.

Answer:

supplement = 152°

Step-by-step explanation:

If the complement is 62° , then

angle = 90° - 62° = 28° ( Complementary angles sum to 90° )

Supplementary angles sum to 180° , then supplement of 28° is

180° - 28° = 152°

Answer:#1 is D

Step-by-step explanation:angles must equal 180 and yk that the angle under e is 39 so 180-39 =141

[tex](a+b)(a-b)=a^2-b^2\\\\(4+2i)(4-2i)=4^2-(2i)^2=\boxed{16-4i^2}[/tex]

Answer:

A

Step-by-step explanation:

We want to simplify the expression:

[tex](4 + 2i)(4- 2i)[/tex]

Notice that this is the difference of two squares. That is:

[tex](a +b)(a-b) = a^2 - b^2[/tex]

We can let a = 4 and b = 2i. Hence:

[tex](4+2i)(4-2i) = (4)^2 - (2i)^2[/tex]

Simplify:

[tex]= (16) - (4i^2) \\ \\ = 16 - (-4) \\ \\ = 20[/tex]

(Note that i² = -1.)

In conclusion, our answer is A.

The control group in the experiment are the classes where the teacher does not greet the students

A control group in an experiment is made up of groups of people that do not receive the experimental treatment.

The purpose of a control group is to allow the researcher study one variable at a time.

Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.

The experimental treatment here is positively greeting the students.

The group that do not receive this experimental treatment are referred to as the control group.

At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

Answer:

solve for k,  k=-1

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

k=-1

Step-by-step explanation:

First step: Distribute

Result: -6-3k-6k=6+3k

Second step: Combine like terms

Result: -6-9k=6+3k

Third step: Add 6 to both sides

Result: -9k=12+3k

Fourth step: Subtract 3k from both sides

Result: -12k=12

Final step: Divide by -12 to both sides

Result/Answer: k=-1
