Answer:
y = - 
x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (- 4.5, 0 ) ← coordinates of intercepts
m = 
= 
= 
= -
The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3
y = - x - 3 ← equation of line
Multiply the number of bags by the ounces in each bag:
8 x 3 1/2 = 28 total ounces.
Divide total ounces by the number of hikers:
28 / 12 = 2.33 ounces per hiker.
1 cup = 8 ounces.
Divide the number of ounces per hiker by the number of ounces in 1 cup:
2.33 / 8 = 0.29 cups per hiker.
The formula for finding a gradient is
y2-y1/x2-x1.
So in your case it will be the following:
Answer:
The factors are (x-7) and (x-4)
Step-by-step explanation:
We are finding the factors of a function from the zeros
The zeros are 7 and 4
We can use the zero product property which is
(x-b)(x-c) = 0 where b and c are the zeros
(x-7) (x-4) =0
The factors are (x-7) and (x-4)
Answer:
those are pretty good! all a's and b's are good! Keep up the good work!!
