Answer:
7
Step-by-step explanation:
f(x) means y, it is equal to the value of y, so f(x) = y
so, f(1) means to find the value of y when the value of x is 1, and that is 7, since 7 is the value of y indicated when the value of x is 1.
I hope this is helpful.
Answer:
15/16
Step-by-step explanation:
4/5 x=3/4
x=(3/4)/(4/5)
x=15/16
Answer:
A. -1/5
B. 8 gallons
C. 75 miles driven
Step-by-step explanation:
Part A is essentially just asking for the slope, which is written as a fraction with the numerator being the number of units the line goes up/down and the denominator being the number of units the line goes left/right. Because the line is going down from left to right, the slope is negative. The slope is -1/5.
Part B can be answered by simply looking at the graph and seeing where the line is at above 175 miles, which is 8 gallons.
Part C can be answered in the same way as Part B, by looking at where the line is at when level with 12 gallons, which is 75 miles driven.
What is the net of the shape? I would say a ball, or a cylinder.
Answer: P ( 3/2, - 1 )
Step-by-step explanation: the formulae that defines the midpoint of a line is given below as
x = (x2 + x1)/2 and y = (y2 + y1)/2
Where x and y are the coordinates of the mid point.
Point A is (-1, 5) hence x1 = - 1 and y1 = 5
Point B is (4, -3) hence x2= 4 and y2 = - 3
For x coordinate, we have that 4 + (-1)/2 = 4 - 1/ 2 = 3/2
For y coordinate, we have that - 3 + 5 / 2 = - 2/2 = - 1
Hence, coordinate of midpoint is P ( 3/2, - 1 )
