Question 1:

D. Multiply/divide both sides by the same non-zero constant.

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

non zero constant is 4:

[tex]x + 4 = 12[/tex]

Question 2:

Yes

[tex] \mathrm{Answer}[/tex]

1. We can get Equation (B) from Equation (A) by multiplying it with 4.

therefore the correct option would be :

C. Multiply / Divide only one side by a non-zero constant.

2. A. Yes, they are equivalent since we can get Equation (B) from Equation (A) by multiplying it with 4.

solve the equation using multiplication and division.

Write the slope-intercept form of the given line. Include your work in your final answer.

Answers

Step 1: Find the slope:
To find the slope, find two points on the graph and count the “rise over run” between the points.
Two points here are (0,-1) and (2,1). To get from (0,-1) to the other point, you need to go “up 2” and then “right 2”. This means your slope is 2/2 or 1.

Step 2: Find the y-intercept:
We can see the y-intercept is (0,-1) on the graph. We’ll use the “-1” from that point for our equation.

Step 3: Put it all together:
The slope-intercept form is y=mx+b, where m is the slope and b is from the y-intercept.
Putting Step 1 and Step 2 into play, we have:
y = x - 1

Note: since m=1, we don’t need to write y = 1x -1. That 1 on the 1x is unnecessary.

Rational numbers are those which can be expressed as a fraction of 2 whole numbers
(2/3 , 1/2 etc)

Irrational numbers are those that CAN NOT be expressed as a fraction of 2 whole numbers
( pi, square root of 2, etc)

*Extra notes to help differentiate*

-An irrational number has endless non-repeating digits to the right of the decimal point.

- Every whole number is a rational number, because any whole number can be written as a fraction. For example, 2 can be written as 2/1

Thomas invested $40,000. He put part of the money in an account paying 2% interest and the remainder
into stocks paying 3% interest. The total annual income from these investments was $1020. How much
did he invest at each rate?
(show work please)

Answers

Answer:

18,000 at 2%

22,000 at 3%

Step-by-step explanation:

x: the amount in account paying 2% interest

y: the amount in stock paying 3% interest

x + y = 40,000

2%. x + 3%. y = 1020

⇒ x = 18,000

y = 22,000

Ivan currently has $ 45 saved. He had been saving $ 9 each week. You spent $ 126 of those savings yesterday. How many weeks have you been saving?

Write an equation that can be used to answer the previous question. First, choose the appropriate shape. Then fill in the blanks with the numbers 45, 9, and 126. Let w be the number of weeks.

please i need the procedure of this pls

Answers

9w + 45 = 126

Ivan earns $9 per week so we would write it as 9w
Add 45 to it because that is what he also saved
Then he spent those savings which was 126.
Now we can find how many weeks he was saving for.

First minus 45 from both sides
9w = 126 - 45 = 81

The divide both sides by 9
w = 9

Ivan has been saving for 9 weeks

Bill's bike wheels have a 26-in. diameter. The odometer on his bike counts the number of times a wheel rotates during a trip. If the odometer counts 200 rotations during the trip from Bill's house to school, how many feet does Bill travel? Round to the nearest foot.

Answers

Answer:

1361 ft.

Explanation:

The circumference of the wheel times the number of rotations equals distance travelled

[tex]C = d\pi[/tex]

Answer:

≈ 1361 ft

Step-by-step explanation:

One rotation is same distance as:

C = πd = 3.14*26 = 81.64 in

Total distance traveled:

200*81.64 = 16328 in

Convert inches to feet:

12 in = 1 ft16328 in = 16328/12 ft = 1360.66666667 ft ≈ 1361 ft

Answer:

7

Step-by-step explanation:

You've said that both triangle are equal.

This means, both are in proportion

Let the unknown side be x

4 : 5 : x = 36 : 45 : 63

Divide LHS by 9

4 : 5 : x = 4 : 5 : 7

Since you may see x and 7 are same. So, the missing side is 7.

Answer:

Step-by-step explanation:

[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex]                      #1 Find same sides  

So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex]                 #2 fill it in.

36BC= 252                 #3 Cross multiply.

[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex]                      #4 Divide by 36

BC= 7                           #5 Here's your answer!

If you want to check, plug the sides in.

[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]

[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]

The siplified fractions should all equal the same number. If they do, the triangles are similar.
