Explain how to subtract 247 from 538?
alexandr402 [8]
1. 538 - 247 = ?

2. 8 - 7 = 1

3. You can't subtract 3 and 4, so you have to take  number from 5 (turning it into a 4) and then you add a 1 right next to 3 (which makes it 13;13 - 4 = 9

4. 4 - 2 = 2

538 - 247 = 291

So the answer is 291.

If G = {(-1, 7),(-8, 2),(0, 0),(6, 6)), then the range of G is
lana66690 [7]

Answer:

\{0, 2, 6, 7\}

Step-by-step explanation:

You are given the relation G = \{(-1, 7),(-8, 2),(0, 0),(6, 6)\}

This means that

f(-1)=7\\ f(-8)=0\\f(0)=0\\f(6)=6

The input values of this relation are -1,\ -8,\ 0,\ 6, so the domain of this relation is \{-8,-1,0,6\}

The output values of this relation are 7,\ 2,\ 0,\ 6, so the range of this relation is \{0, 2, 6, 7\}

PLEASE HELP ME SEE IF MY ANSWERS ARE CORRECT!!!!!!!
Lena [83]
So first one
'how many solutions does 2x-y=-5 and 2x+y=5 have?'
add and get
2x-y-5
plus
2x+y=5

equals
2x+2x+y-y=5-5
4x=0
x=0 always
solve for y
4(0)+y=5
y=5
the solution is (0,5)
only <u>ONE </u>solution






one way is to subsitute
just remember that it is in (x,y) form so
the pont (1,2) means that 1 solution is x=1 and y=2 so subsitute and find that
the first one is the answer you are correct





just look at the graph
the solution is the intersection
it seems to be at a point that is 3 units to the right and -6 units up (6 units down)
so the solution is (3,-6)
yo are corect








subsitution
y=y
therefor
the answe ris (-4,-14) if you did the math correctly











#8 is correct

# 9 is correct




# 10 the answe ris bananas=0.40 pears=0.60


the  last one you got it wrong, remember to check your answer to the graph for commonsense
then answer is (-2,5) and (1,2)
