3a + 3b-2c-2d
a= number of hearts
b= number of diamons
c= number of clubs
d= number of spades
if you draw 3hearts, 2 diamonds, and 1 spade, just replace a=3, b=2, c=0, d=1
3(3) + 3(2)-2(0)-2(1)
Multiply each term and add the results:
9+6-0-2 = 13
13 points
Answer:
Line "L" has the slope of 1 and line "K" has the slope of 2.
In order to graph a line with the slope of 
think of the numerator as the "rise" (how much you move up/down on the y-intercept) and the denominator as the "run" (how much you move to the side on the x-intercept)
Step-by-step explanation:
A slope of "1" is simply 
so you rise up one and move to the right once. This clearly demonstrated on line "L".
A slope of "2" is 
so you rise up two and move to the right once, as is demonstrated on line "K".
For the 2nd question, line "A" will have a slope of therefore it will move up once and then to the side three times. It will look like the image attached to this answer.
I hope this helped! Feel free to ask questions if needed!
Answer:
60.32
Step-by-step explanation:
126%=1.26
60.32*1.26=76.0032
76.0032≈76
