We have the function
and we want to find a function that has the same y-intercept than the previous function.
First, let's find the y-intercept by subtituting 0 for 'x'.

Now that we found that y-intercept =-3, any lineal function of the type:
will have the same y-intercept. Where 'a' can take all the real values.
Also, any quadratic function of the type:
will have the same y-intercept. Where 'a' and 'b' can take all the real values.
Answer:
A. y + 6= -2(x - 4)
Step-by-step explanation:
Let A(a , b) be a point of the line
and m be the slope.
The equation of the line in Point-slope form :
y - b = m (x - a).
…………………………
Given :
Slope = -2
A(4 , -6)
Then
Point-slope equation : y + 6= -2(x - 4)
15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100
Answer: C
Step-by-step explanation:
This describes an expotential function
At t = 0, P = 70
Therefore, C = 70
P = 70 e^kt
Solve for k by plugging in (4,360)
k = 0.4094
plug in t(7 hours)
70 e^(0.4094*7)
The answer roughly equals C
Answer:
343
Step-by-step explanation:
Finding? How many people with a library card should he expect in the population?
Important? Population = 700. Sample 1= 53%. Sample 2 = 51%. Sample 3 = 43%.
How? Average the 3 samples percentages together. The percent sign tells us what the sample size is (% = out of 100). Set up the proportions for library card to sample size and then library card to population. Cross multiply.
