Answer:
in y = mx + b the gradient is m
in y = 4 - 5x = -5x + 4 the gradient is -5
Answer:
Hence, the graph is decreasing in the interval: –4 ≤ x ≤ 2 ( option: B is correct)
Step-by-step explanation:
We have to define the interval in which the graph of the given function is decreasing.
Clearly by looking at the graph we could see that the graph is first increasing till x<-4.
and then it decreases in the interval [-4,2] since the value of y changes from y=9 at x= -4 to y= -9 at x=2.
also after x=2 the graph increases till x=6 and after x=6 the graph is constant i.e. the graph is represented by the line:
y=5 in the interval x≥6.
Hence, the graph is decreasing in the interval:
–4 ≤ x ≤ 2 ( option: B is correct)
Answer:
y = 2x/3 + 0 for x < 0
y = -3x for x ≥ 0
Step-by-step explanation:
Blue line
line rises 2 units for each 3 units of run so slope is 2/3, intercept is 2
y = 2x/3 + 0 for x < 0
Red line
line falls 3 units for each 1 unit of run so slope is -3, y intercept is 0
y = -3x
Ok so I am not exactly sure if you want to know how many whole cups can be added or simply how many 2/3 cups make up 10, but heres what I found.
So to find how many 2/3 is in 10 cups you simply have to divide
10/(2/3) = 15
So 10 cups of flour is 15 (2/3) cups of flour.
Hope this helps :)
