True.
E.g. (x-1)(x-2) versus 100(x-1)(x-2)
They have same roots of x= 1 or 2, but the second equation is 100 times stretching of the first one vertically
Y=Mx+b
Slope/M= -1
X= 3
Y= -1
-1 = -1(3)+b
-1 = -3 + b
Add +3 to -3 and -1 to cancel -3 out to get (b)
-3+3 = 0 cancel it
-1 +3 = 2
So, b = 2
In an equation it will be written as
y= -1x + 2
In standard form it will be
1x + y = 2
But your official answer will be
B= 2
Y= -1x+2
B. D represents the amount of dimes and q represents the amount of quarters so that equals 20 coins total. 0.25q is the amount of quarters multiples by their cost, when added to 0.1d it equals 4.25.
10/15 is the probability that the gumball is not green
Answer:
(1, 4), (2, 8), (3, 12)
Step-by-step explanation:
The ratio if the number if books to the cost in dollars is 1 : 4
To plot on a coordinate grid, we first look at the horizontal direction (x-axis)
Take the number of books to be values of the x-coordinate.
Start at the origin and travel the necessary distance to the left or the right then move up or down in the vertical direction to mark the y-coordinate.
The corresponding cost to be the values of the y-coordinate. Mark or plot at the intersection of the two numbers.
