Answer:
Step-by-step explanation:
we have
Remember that
To predict a value for y, when x = 4
substitute the value of x in the equation
so
Answer:
D
Step-by-step explanation:
The parabola opens up. Which means the vertex is the minimum value.
Every point on this line has the same y coordinate, which is -2. There is no "rise" at all so rise = 0 while the "run" is any nonzero value you want. If you made the run be say 2, then
slope = rise/run = 0/2 = 0
The slope is 0
Answer: D) 0
note: all horizontal lines like this have a slope of 0. It doesn't matter what the y intercept is
Answer:
144 grams
Step-by-step explanation:
the total mass of the bowl of grapes includes the bowl. to get the mass of the grapes, we need to subtract the mass of the bowl. 265 grams - 121 grams is 144 grams.
(x, y ) → (- 1, 3 )
The solution to the system of equations is the point of intersection of the 2 lines
From the graph, that is (x, y ) → ( - 1, 3 )
We can confirm by solving algebraically
Since both equations express y in terms of x we can equate the right sides
- x + 2 = - 6x - 3 ( add 6x to both sides )
5x + 2 = - 3 ( subtract 2 from both sides )
5x = - 5 ( divide both sides by 5 )
x = - 1
substitute x = - 1 into either of the 2 equations for y-coordinate
y = - x + 2 = 1 + 2 = 3
solution is (x, y ) → (- 1, 3 )
