Second one is 4
Third one is P’ (4, -1)
Step-by-step explanation:
Answer:
2x/3
Step-by-step explanation:
-1^2 is just 1 am and that + 2 is 3 f(x) divided by g(x) is 2x/3
Answer:
The three numbers are 12, 11, and 6
Step-by-step explanation:
Let
First Number be x
Second Number be y
Third Number be z
Now, we can come up with equations from the word problem.
The 2nd is 1 less than 1st means:
y = x - 1
3rd is 5 less than 2nd means:
z = y - 5
1st is TWICE as large as 3rd means:
x = 2z
We have 3 equations. Let's put 3rd into 1st, we get:
y = 2z - 1
Now put this into 2nd equation, we get:
z = 2z - 1 - 5
Solving for z:
5 + 1 = 2z - z
z = 6
We know x = 2z, so x = 2(6) = 12
x = 12
and y = x - 1, this means y = 12 - 1 = 11
y = 11
Answer:
Step-by-step explanation:
Use the slope-intercept formula: where m is slope and b the y-intercept.
Use the slope formula for when you have two points:
Rise over run is the change in the y-axis over the change in the x-axis. Insert values:
Simplify parentheses (negative+negative=positive)
Simplify
2 is the slope:
Now use one of the points to find the y-intercept by substituting the x and y values into the equation. Solve for b:
(4,7)
The y-intercept is -1. Insert into the equation. Change the + symbol to -:
Done.
