It will be 18 days.

We want the least common multiple (LCM) of 6 and 9. First we find the prime factorization:
6 = 2*3
9 = 3*3

They have a 3 in common; we use this first in the LCM. Then we take the "leftover" factors, 2 and 3:
LCM = 3*2*3 = 18

What is the equation of the line connecting (1,5) and (4,14)?

german

To find the slope of the line:
(y2-y1)/(x2-x1)
(14-5)/(4-1)=(9)/(3)=3

Only one of your 4 possible answers has 3 as a slope. However, plugging in each point into the y=mx+b equation, the y-intercept consistently comes out as 2..
y=mx+b
14=3(4)+b b=2
5=3(1)+b b=2
y=3x+2
If there is a consistent, positive slope (from your question, this does not seem to have a quadratic as an option), 3x+5 is not even a viable solution because x=1 when the y-value is 5 (and thus no other x value {0} could have a y-value of 5). It seems as though you have a typo on your hands. Hopefully this helps?

Tara places a picture in a picture frame. The width of the picture is x inches, and the length of the picture is 2 inches more t

CaHeK987 [17]

Refer to the diagram shown below.

The dimensions of the outside of the picture rame are:
Width = x + 1 + 1 = x + 2 inches
Length = (x+2) + 1 + 1 = x + 4 inches.

The perimeter of the outside of the picture frame is 28 inches.
Therefore
2(x + 2) + 2(x+4) = 28

Solve for x.
2x + 4 + 2x + 8 = 28
4x + 12 = 28
4x = 16
x = 4 inches

Answer: 4 inches
