Answer:

298 points

Step-by-step explanation:

First, I added 245, 672 and 437 for 1,454.

245+672+437=1454

Then, multiply 438 (Anne's average) by 4 for 1,752.

4(438)=1752

After that, subtract 1454 from 1752 for 298 points in game 4.

1752-1454=298

(A strategy for that you could use is subract the larger ending two digits from the smaller one, then subtract that from 100. Then subtract the front digits of the second number from the front digits of the first number minus one.

So here, 54 - 52 = 2

100 - 2 - 98, so that's the last two digits.

(17 - 1) - 14 = f

16 - 14 = 2 = f, so that's the front digit.

how would you find the slope of x- y=-2? and explanation step by step would help me so much to understand this and no longer hav
shepuryov [24]

Answer:

y=x+2

Step-by-step explanation:

Isolate y to get the slope.

x-y=-2

move x by subtracting from both sides to get:

-y=-2-x

Make -y positive by multiplying both sides by -1:

y=2+x

Reorder the problem:

y=x+2
