Answer:
x *2 + (28-x)*4 = 100
Step-by-step explanation:
Given
Total number of questions in the paper = 28
Out of these 28 questions let us say that x number of questions are of 2 points and 28-x questions are of 4 points.
Also, the complete test is of 100 marks
Thus, the linear equation representing the
x *2 + (28-x)*4 = 100
Answer:
The temperature would be 55 degrees fahrenheit
Answer:
A. -415m
Step-by-step explanation:
-300 meters is the starting point.
Then, the submarine goes 115m further below the surface, which can be represented as -115.
Add -300 and -115 and you get -415m.
Answer:
C: F(x)=x^2-0.5
Step-by-step explanation:
When the x is squared it's a parabola. A linear graph is shaped like a straight line, while a parabola is curved inward. I have included a graph of what that function would look like (tap/click on it to see the full graph.)
