The regression equation y=0.5x+1.3 approximates the number of hours it takes to arrange a dinner event, y, given the number of p
Sphinxa [80]

It would be C.

For example, say 1 person comes. This would be x=1. Plugging this in gives you,

y=0.5 + 1.3

This shows that C is true since x is always going to be multiplied by 0.5.

1.3 would be the base amount of time it takes to arrange since if it the y-intercept.

Find the greatest common factor of 26 and 14.
Molodets [167]

Answer:

2

Step-by-step explanation:

A factor is a number that can evenly divide into another number.

Let’s list all the factors of both numbers.

26: 1, 2, 13, 26

14: 1,2, 7, 14

Now find the GCF, or greatest common factor. The biggest number that is a factor of both 26 and 14 is 2.

Therefore, the GCF of 26 and 14 is 2.

Which equation has x=2/3 as a solution and why?
eduard

There are an infinite number of different equations that have
x=2/3  as the solution, or as one of several solutions.

You didn't show us your list of choices, so we can't help you
pick the right one.

Just take each choice, one at a time.  Write ' 2/3 ' in place of 'x'
in each equation, and simplify everything.  You'll wind up with
one equation that's true, and the others will say something that's
nonsense. 

The one that's true is the one that has  x=2/3  as its solution.
