Answer:

9>a

Step-by-step explanation:

the side with the bigger opening means that side of the inequality has a greater value so since 9 is greater than a the bigger opening will go to 9.

Answer:

9>a

Step-by-step explanation:

The greater than symbol is >

The less than symbol is <

It can be helpful to imagine the signs as little crocodile mouths. They will turn their heads to the biggest catch, or in this case, the greater number. So the open end of the sign will be towards the greater number.

The automaker of your new car recommends an oil change following the first 5,000 miles and then every 3,000 miles thereafter. If

Jlenok [28]

To determine how many oil changes you will need the first year, you can calculate the number of miles driven the first year and then use that to determine how many groups of 3000 miles you will drive after the first 5000 miles.

1. 52 x 250 = 13000 miles

2. 13000 miles - 5000 miles (1 oil change) = 8000 miles

3. 8000 miles - 3000 miles (1 oil change) - 3000 miles (1 oil change) = 2000 miles

The first year, you will need 3 oil changes.

What is the image of the point (8,4) after a rotation of 90° counterclockwise about the origin?<br>

Alenkinab [10]

<h3>Answer: (-4, 8)</h3>

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

Explanation:

The 90 degree counterclockwise rotation rule we use is

$(x,y) \to (-y,x)$

the x and y coordinates swap places, and we change the sign of the first coordinate after the swap.

After using that rotation rule, we would go from (8,4) to (-4, 8) which is the final answer.

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

Extra info (optional section):

Define the following three points

A = (0,0)

B = (8,4)

C = (-4,8)

Use the slope formula to find that AB and AC have slopes of 1/2 and -2 in that order.

Those slopes multiply to -1, since (1/2)*(-2) = -1. This is a property of any two perpendicular lines as long as neither line is vertical and neither is horizontal. So this is sufficient to prove that the lines are perpendicular. This further means that a 90 degree rotation has taken place.
