The answer should be D. 10.
Substitute x for the number 3 in the first equation.
f(x)=2(3)+1, then solve to get x=7
Substitute 7 for x in the second equation
g(x)=(3(7)-1)/2
g=(21-1)/2
g=(20)/2
g=10

The point-slope form:
We have the point (8, -4) and the slope m = -5/6. Substitute:
Answer:
A'(5,-11)
Step-by-step explanation:
Your only changing the y if you are reflecting over the x-axis but change the x if you are reflecting over the y-axis.
Answer:
the result is a positive number not a negative number
Step-by-step explanation:
a - ( -b)
We know that subtracting a negative is like adding
a+b
This would result in a positive number
Answer:
c = -6
Step-by-step explanation:
To find the value of c to make the line pass through the point K = (2, -3), we just need to use the values of x = 2 and y = -3 in the equation, then we find the value of c.
So, we have that:
y - 1.5*x = c
(-3) - 1.5 * (2) = c
-3 - 3 = c
c = -6
So the value of c is -6
To check if the value is correct, we can use the value x = 2 and see if the value of y is -3:
y - 1.5*x = -6
y - 1.5*2 = -6
y - 3 = -6
y = -6 + 3 = -3
So it's correct.
