What is Step 5 on solving systems by elimination?

Answer:

Given AD = 7 and DB = 12, to find AB you need to add them

AB = 12+7

AB = 19

The measure of the line segment AB is 19 units.

Suppose we've two endpoints of a line segment as:

A(p,q), and B(m,n)

Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

[tex]x = \dfrac{p+m}{2}andy = \dfrac{q+n}{2}[/tex]

We are given that;

AD = 7, and DB = 12

Now,

To find the measure of the line segment AB, we need to use the segment addition postulate. The segment addition postulate states that if a point is between two other points on a line segment, then the sum of the lengths of the two smaller segments is equal to the length of the larger segment.

In this problem, D is between A and B, so we can apply the segment addition postulate and write:

AD + DB = AB

Substituting the given values of AD and DB, we get:

7 + 12 = AB

Simplifying, we get:

19 = AB

Therefore, by the given point the answer will be 19 units.

Answer:

41

Step-by-step explanation:

15+26=41

Answer:

41 minutes

Step-by-step explanation:

If she jogged 15 minutes more on Sunday than Saturday, we can find how many minutes she jogged on Sunday by adding 15 to Saturday's amount:

So, add 15 to 26:

15 + 26

= 41

So, she jogged 41 minutes on Sunday.

Answer:

[tex]\frac{n+2}{8}[/tex] has a remainder of 7 ⇒ B

Step-by-step explanation:

In m ÷ n = c + [tex]\frac{r}{n}[/tex] ,

Let us use the facts above to solve the question

∵ [tex]\frac{n}{8}[/tex] has a remainder of 5

→ Let us find the first number divided by 8 and give a reminder of 5

  that means let the quotient = 1

∵ n = (8 × 1) + 5 = 8 + 5

∴ n = 13

∵ [tex]\frac{n+x}{8}[/tex] has a remainder of 7

→ Let us find the first number divided by 8 and give a reminder of 7

  that means let the quotient = 1

∵ n + x = (8 × 1) + 7 = 8 + 7

∴ n + x = 15

∵ n = 13

∴ 13 + x = 15

→ Subtract 13 from both sides

∴ 13 -13 + x = 15 - 13

∴ x = 2

∴ [tex]\frac{n+2}{8}[/tex] has a remainder of 7

Answer:

Step-by-step explanation:

15 is the y-intercept

-7 is the slope

Answer:

[tex]a_{n}[/tex] = 22 - 7n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

8 - 15 = 1 - 8 = - 7

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 7 , then

[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

Answer:

19)   D (-8, -2)

20)  B (0, 8)

Step-by-step explanation:

-x - y = 10

-6x + 11y = 26

-x - y = 10

-x = 10 + y

x = -10 - y

-6x + 11y = 26

-6(-10 - y) + 11y = 26

60 + 6y + 11y = 26

60 + 17y = 26

17y = -34

y = -2

-x - y = 10

-x - (-2) = 10

-x + 2 = 10

-x = 8

x = -8

_______________

-x + y = 8

3x + 2y = 16

-x + y = 8

y = 8 + x

3x + 2y = 16

3x + 2(8 + x) = 16

3x + 16 + 2x = 16

5x + 16 = 16

5x = 0

x = 0

-x + y = 8

-0 + y = 8

y = 8

You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y

y=1

Answer: y =-1

Step-by-step explanation:y =-1

Last option is correct.

Step-by-step explanation:

The given equation is

In order to solve for y, we need to isolate y.

In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.

The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation
