What is a straight line ?

A straight line is a line passing through the x-y plane that has equal intercepts with respect to the x axis and the y-axis. The slope of a straight line is always equal. The straight line is also satisfied by the coordinates points in the x and y axis respectively.

How to identify the points on the given line y = 2x ?

To identify the points satisfied by any given equation, we have to replace the points given in the following equation.

Taking first point in option (A) , (16,8) , we have y = 8 and x = 16 which does not satisfy the equation y = 2x .

Taking second point in option (B) , (1,3) , we have y = 3 and x = 1 which does not satisfy the equation y = 2x .

Now from the following options, checking points in Option (D) where x = 3 and y = 6 which satisfies the equation y = 2x .

Also checking the points in Option (F) where x = 5 and y = 10 which satisfies the equation y = 2x .

The following points that are on the line given by the equation y=2x are Option(D). (3,6) and Option(F). (5,10) .

Mrs. Quotient asked her students to simplify each of the expressions below. Which of the numbered choices represents the expressions which simplified to the same result? A 71 B 72 C 73

Answers

Answer:

A and B

Step-by-step explanation:

Mrs. Quotient asked her students to simplify each of the expressions below. Which of the numbered choices represents the expressions which simplified to the same result? A 126/2 B 23 × 3 C 3 × 21

When simplifying an algebraic expression, the following steps are needed to be taken.

Firstly, remove parenthesis by multiplying the constant with the term in the parenthesis or remove parenthesis using exponent rules for parenthesis in exponent form.

Secondly Combine terms by adding coefficients of terms with the same order and lastly sum all constant.

A) 126/2

Applying the division rule give:

126/2 = 63

B) 23 × 3

Applying multiplication rule gives:

23 × 3 = 69

C) 3 × 21

Applying multiplication rule gives:

3 × 21 = 63

Both the results of expression A and expression B are simplified to the same result

In the graph of the equation, 2x – 8y = 32, what is the y-intercept (b) of the line? Express the answer as an ordered pair.

Answers

2x-8y=32

Add 8y to both sides

2x-8y+8y=32+8y

2x=8y+32

Now just divide both sides by 2

2x/2= 8y+32/2

x= 4y+16

So the y value is 4 and the x value is 16

The y-intercept is 4

Find the missing digits. 34 x □5

Answers

Answer: i think 3

Step-by-step explanation:

To find the missing digit in the multiplication problem 34 x □5, we need to determine what number should replace the blank space.

To solve this, we can use basic multiplication principles.

First, let's look at the units digit. When multiplying any number by 5, the units digit of the product will always be either 0 or 5. Therefore, the units digit of the missing number is either 0 or 5.

Next, let's consider the tens digit. In this case, it's 4. To find the tens digit of the product, we need to multiply the tens digit of the multiplicand (3) by the missing digit. If we multiply 3 by 5, we get 15, which means the tens digit of the product is 5. However, if we multiply 3 by 0, we get 0, which means the tens digit of the product is 0.

Therefore, we have two possible answers: 305 and 345. Both of these numbers are valid options for the missing digit in the multiplication problem 34 x □5.
