ZanzabumX [31]2 years ago

Answer:

The slope is -1

Y-intercept is (0, -6)

Equation is y = -1x - 6 or y = -x - 6 either is right

Step-by-step explanation:

We already know that the slope is negative because the line is pointed this way \ pointed up to the left.

You have to do rise/run to find the slope.

The rise is 6 and the run is 6

6/6 = 1 since the line is negative the slope is -1x or -x

The y intercept is -6

Use the point (-2, -4)

Plug in

-4 = -(-2) + b

-4 = 2 + b (subtract 2 on both sides)

-6 = b

y = -x - 6

Hope this helps ya!!

Multiply hourly rate by hours worked:

Saturday 7 hours x 9.00 = 63.00

Multiply by hours : 9.00 x 4 = 36.00

Add the days together: 63 + 36 = 99.00

He earned 99.00

Really struggling plz help with all of them thanks
ollegr [7]
First, look at the whole number if it is 12, it will go near the 1 on the number line, next look at the fraction,
if its 1/2 change it to be 2/4. Next count the lines in between the number. There are 4 lines. If it is 3/4, count 3 lines and put the fraction there. So 41/4 would be the 4 and 1 line next to it.

What is the area?<br> 2 yd<br> 8 yd<br> 5 yd
MrRissso [65]

Answer:

28

Step-by-step explanation:

I assume the polygon is a trapezoid with parallel bases of 2 yd and 5 yd, and an altitude of 8 yd.

area of trapezoid = (base1 + base2)h/2

area = (2 yd + 5 yd)(8 yd)/2

area = 28 yd²

N is a positive integer
Murrr4er [49]

Part (1)

n is some positive integer. Let's say for now that n is even. So n = 2k, for some integer k

This means n-1 = 2k-1 is odd since subtracting 1 from an even number leads to an odd number.

Now multiply n with n-1 to get

n(n-1) = 2k(2k-1) = 2m

where m = k(2k-1) is an integer

The result 2m is even showing that n(n-1) is even

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

Let's say that n is odd this time. That means n = 2k+1 for some integer k

And also n-1 = 2k+1-1 = 2k showing n-1 is even

Now multiply n and n-1

n(n-1) = (2k+1)(2k) = 2k(2k+1) = 2m

where m = k(2k+1) is an integer

We've shown that n(n-1) is even here as well.

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

So overall, n(n-1) is even regardless if n is even or if n is odd.

Either n or n-1 will be even. If you multiply an even number with any number, the result will be even.

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

Part (2)

n is some positive integer

2n is always even since 2 is a factor of 2n

2n+1 is always odd because we're adding 1 to an even number. The sequence of integers goes even,odd,even,odd, etc and it does this forever.

-----------

Another way to see how 2n+1 is odd is to divide 2n+1 over 2 and you'll find that we get (2n+1)/2 = 2n/2+1/2 = n+0.5

The 0.5 at the end is not an integer, so there's no way that (2n+1)/2 is an integer; therefore 2n+1 is odd.
