For which function will both ordered pairs (3, 6) and (4, 8) be solutions?y = x + 3
y = 2x
y = x + 4
y = 12 - x

Answers

Answer 1
Answer: So you have two x-coordinate:

x=3 and x=4.

Let's test first option:

for x= 3, we have y = (3) + 3 = 6, which matches (3, 6)

Now for x=4, we have y = (4) + 3 = 7 which doesn't match (4, 8).
Do the same for any other options.

You should get B, y = 2x.

indira predicts that the actual difference of 19-7.82 will be greater than the estamate of19-8 =11. is indira correct? explain how indira might have arrived at that prediction without subtracting the actual numbers.

Answers

7.82 is a little less than 8 (it rounds to 8). 

Therefore 19 - 7.82 will be a little more than 11

To be more accurate .82 is .18 away from 1

Therefore the exact answer would be 8.18

0.0052 scientific notation

Answers

To put a number into scientific notation, we multiply or divide the number by 10 over and over until we have a number between 1 and 10.  But we can't just change a number so we have to account for what we did by describing how many times we multiplied or divided with exponents.

Each time we multiply by 10 the decimal moves 1 place to the right.  Each time we divide by 10 the decimal moves 1 place to the left.  The exponent we use will describe the number of times we moved the decimal to the right or left.  The exponent will be positive or negative to describe the direction we need to move the decimal to represent our original number.

I know... that sounds confusing, but it's really easy!  Let's do yours...

0.0052

Now we need to move the decimal to get a number between 1 and 10.  So we move the decimal 3 places to the right to get 5.2

Now we have to describe how to get to the original number with the exponents.  We moved the decimal 3 places right so to get our number back we would have to move it back 3 places to the left so  negative exponent 3...  Here's how we represent it..

5.2 x 10^-3

So what that says is if we take 5.2 and divide it by 10 three times,we will get our original number.

Answer:

5.2 x 10^-3

By how much is (3/4 + 1/12 + 2/3) greater than 1 ​

Answers

Hey there!

3/4 + 1/12 + 2/3

= 5/6 + 2/3

= 5/6 + 4/6

= 5 + 4 / 6

= 9 / 6

= 9 ÷ 3 / 6 ÷ 3

= 3/2
≈ 1.5


1.5 - 1 = 0.5

Therefore, your answer is: 0.5
