There are different types of equations of lines.
There are these three main forms, but I'll focus on just 2:
Slope-Intercept Form:
y = mx + b
Where,
"m" = slope
"b" = y-intercept
Point-Slope Form:
y - y1 = m(x - x1)
Where,
"m" = slope
"y1" = A y point on the graph
"x1" = A x point on the graph that correlates with the y value.
y = 6x - 12
Is in the same form of Slope-Intercept:
So,
y = 6x - 12
m = 6
b = -12
So our slope is,
6
Keep in mind if it was a fraction (Example: 6/5, then the slope is 6/5) the slope will be the entire fraction.
Also remember slope is the RISE over the RUN meaning it is the y value over the x value. So in this case we would go UP 6 and right 1 (because 6 is understood as 6/1).
Answer:
$3.49
Step-by-step explanation:
-The z value is calculated by the formula:
Where are the mean and standard deviation respectively and is the price of the random selection.
#We substitute and solve for :
Hence, the mean price of a box of cereal is $3.49
Answer:
15500 pounds
Step-by-step explanation:
The weight of one load is 4 tons and the weight of other load is 7500 pounds.
We know that, 1 ton = 2000 pounds
4 tons = 8000 pounds
Total weight = 8000 pounds + 7500 pounds
Total weight = 15500 pounds
So, the total weight of sand is 15500 pounds.
W=3/4L
P=2L=2W
70=2L+2(3/4L)
70=2L+6L/4
70=2L+1.5L
70=3.5L
L=70/3.5
L=20 FT. ANS. FOR THE LENGTH.
W=4/4*20=15 ANS. FOR THE WIDTH

but the last bus will not be full all the way
