Yesterday, Jim had b baseball cards. Today, he gave 13 away. Using b, write an expression for the number of cards Jim has left.

1 answer:

8 0

Jim started with b baseball cards and gave 13 away. So, that means we take away from his starting amount or b.

So, b - 13 is the expression you are looking for.

When drawn in standard position, an angle a has a terminal ray that lies in the second quadrant and whose sine is equal to 9/41.

Semenov [28]

Answer:

$\frac{40}{41}$

Step-by-step explanation:

We have the angle in standard post has a sine ratio of

$\frac{9}{41}$

This means the opposite side length of the corresponding right triangle is 9 units and the hypotenuse is 41 units.

Using Pythagoras Theorem, the adjacent side length can be found using:

${x}^{2} + {9}^{2} = {41}^{2}$

This implies that:

${x}^{2} = {41}^{2} - {9}^{2}$

${x}^{2} = 1600$

$x = \pm \sqrt{1600}$

$x = \pm40$

The cosine ratio is adjacent over hypotenuse.

$= \frac{ \pm40}{41}$

Since we are in the second quadrant, the cosine ratio is negative;

$= - \frac{40}{41}$

Please help me with these last two my teacher didn’t explain it really well

GrogVix [38]

So since you know that this is a line you can use the slope intercept form which is y=mx+b. M being the slope and B being the y intercept. So for 5a. It is asking for the equation so you just plug in the numbers into y=mx+b.

y=5x-2

For 5b all you have to do is plug in 0 for y in the equation above.

So it will be 0=5x-2. So you simplify it.

Subtract 2 to both sides and you get -2=5x

THen divide by 5 on both sides to isolate the x and so you will get -2/5 =x.

So the answer would be the value of x when y is 0 is -2/5

I really hope that this helped you in some way. If you have any questions feel free to ask me. Have a great day :)

Additive Inverse Property<br><br> 0 = 5c + <br><br> what is the missing number?

Vilka [71]

Answer:

Hi there!

Your answer is:

-5c

The full equation is:

0= 5c + (-5c)

Step-by-step explanation:

The additive inverse is whatever two numbers, when added, equal 0. We have a positive 5c here. To get rid of 5c, we must subtract 5c from 5c

I hope this helps!
