Answer:
B
Step-by-step explanation:
By inspection we can see that the slope of the line is m = 2/5; as x increases by 5, y increases by 2. Next, also by inspection, we see that the y-intercept is (0, 3/2). Using the slope-intercept formula y = mx + b, we get y = (2/5)x - 3/2.
Let's take a look at Answer B: If we divide all three terms by 2, we get:
(2/5)x - y > 3/2. This matches the equation found earlier, y = (2/5)x - 3/2 if we rewrite (2/5)x - y > 3/2 as (2/5)x - 3/2 > y.
Thus, all points that satisfy this inequality are BELOW the y = (2/5)x - 3/2,
Answer B is the correct one.
Answer:
7x - 5 7x - 5
(f/g) = ----------------- = ----------------
2x - 4 2(x - 2)
Step-by-step explanation:
Given f(x) = 7x-5 and g(x)=2x-4, we form the quotient f/g as follows:
7x - 5 7x - 5
(f/g) = ----------------- = ----------------
2x - 4 2(x - 2)
Note that this is not defined for x - 2, due to division by zero.
Answer: 70
Explain:
80*5 = 400
this tells us that the total scores before
dividing must be 400
400 - (78+88+83+81) = 70
this tells us that we lack +70
in conclusion, to get an average of 80% on Sara's test scores; She must receive a grading of 70% in her next test.
Answer:
240m^3, 240m3, 240 meters cubed
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply the width, length, and height.
5*6*8=240.
I believe that you would have to divide by four.
