BabaBlast [244]

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

Step-by-step explanation:

The floor score must be higher than 15.133 and lower than 15.500

The missing digit must be an integer.

Then all the possible scores are: 15.166 , 15.266 , 15.366 and 15.466

Then all the possible digits are 1 , 2 , 3 and 4

The difference between her vault score and her uneven bar score is

15.500 - 15.133 = 0.367

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

2x + 4y = 12 y = x – 3 What is the solution to the system of equations? (–1, 8) (8, –1) 5 1/2 1/2 5

Goryan [66]

Answer:

The solution is (8, -1).

Step-by-step explanation:

2x + 4y = 12..........(1)

y = 1/4x – 3 ..........(2)

Substitute y = x - 3 in equation (1):

2x + 4(1/4x - 3) = 12

2x + x - 12 = 12

3x = 24

x = 8.

Now substitute for x in equation (2):

y = 1/4 *8 - 3

y = -1.

If y2 = x3 + 2, which statement is true? The equation is a function at all values of x. The equation is not a function. The equa

tatyana61 [14]

Answer:

The equation is not a function.

Step-by-step explanation:

We are given that

$y^2=x^3+2$

$y=\pm\sqrt{x^3+2}$

Function: It is mapping between the values of two sets A and B.

Each element of A has unique value in set B.

By definition of function

In given function

y has no unique value for each value of x.

Substitute x=0

$y=\pm \sqrt{0+2}=\pm \sqrt 2$

Hence, it is not a function.

Lauren Rob need to find a decimal equivalent to 39/50 Laura said she could write an equivalent fraction with 100 as the denomina

Lina20 [59]

Answer:

Laura and Rob are correct

Step-by-step explanation:

we have

39/50

1) Rob said he could divide the numerator by the denominator

so

using a calculator

39/50=0.78

Rob is correct

2) Laura said she could write an equivalent fraction with 100 as the denominator to converted into a decimal

so

Multiply by 2/2

(39/50)*(2/2)=78/100=0.78

Laura is correct

therefore

Laura and Rob are correct
