Answer:
y= 10x-38
Step-by-step explanation:
Equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
Given that m=10,
y= 10x +c
Now substitute the coordinates into the equation.
When y=12, x=5,
12= 10(5) +c
12= 50 +c
c= 12 -50
c= -38
Thus the equation of the line is y= 10x -38
Answer:
a. at zero years of education, income equals $1500
Step-by-step explanation:
The equation for income 'I', as a function of years of education 't' is given by:
Where b is the regression coefficient and a is the intercept.
The intercept is the value assumed by the function for t = 0 years of education:
Since the income function measures income in $1,000s, at zero years of education, income equals $1500
Answer:
B the service fee for coming to look at the machine
Step-by-step explanation:
f(x) is a multiple of the cosine function. g(x) is a multiple of the sine function. Both the cosine function and the sine function have a maximum value of 1, so the magnitude of the multiple will determine which function has the largest maximum value.
The multiple for f is 2; the multiple for g is 3, which is greater than 2. Hence g(x) has a larger maximum value than f(x).
