The function you're given is in point-slope format, which is one of the easiest ones to graph. The basic form of the format is;
y=ax+b
Where a is the slope and b is the y-intercept.
As you can see, in y=-13+3x, the positions of a and b are switched, but it is essentially the same question.
From here we can tell that the y-intercept is -13, meaning that there is a point on the line that rests at (0,-13)
To find the other points, we can do rise-over-run using the slope of 3 given to us. What happens here is that for every 1 unit you go to the right (positive), you rise 3 units up.
For example, if we perform this on the y-intercept (0,-13):
(0+1, -13+3)
(1,-10)
With these two points, you can graph the line representing the temperature.
An exponential growth model has the form:
we know that the initial population was 3000 and that after seven years the population was 3525, plugging this vales and solving for the unknown we have:
Therefore the missing part of the function is 0.083
Answer:
16.8 or 16 whole 4/5
Step-by-step explanation:
14 divided by 5/6
take reciprocal
14 x 6/5
84/5
16.8
Answer:
0
Step-by-step explanation:
Y-intercept is where the line touches the y-axis, in this case it was the origin (0,0) so the y-intercept is 0
Answer:
x = 8
Step-by-step explanation:
Here, we want to find the value of x
According to the theorem;
45 = 1/2(147 - (7x-5))
90 = 147 -7x + 5
90 = -7x + 147
7x = 147-90
7x = 57
x = 57/7
x = 8.142 which is approximately 8
