Answer:
AC with endpoints at A(1; -1) and C(5; 3)
Answer:
x = 4 ± 
Step-by-step explanation:
To complete the square
add (half the coefficient of the x- term)² to both sides
x² + 2(- 4)x + 16 + 5 = 16
(x - 4)² + 5 = 16 ( subtract 5 from both sides )
(x - 4)² = 11 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ± ← exact values
Answer:
There is no solution
Step-by-step explanation:
The slopes are the same and the y-intercepts are different.
Think of this as the slope as an amount you get per week and y-intercept as how much you start off with. You have a friend that starts off with 10 dollars and gains 5 dollars every week and you start off with 5 dollars and gains 5 dollars every week. Will you ever catch up to your friend if you and your friend don't spend any money? I don't think so. The solution to a set of equations is when both equations have the same y value with the same x value.
Your welcome for the help and comment if you have any questions! :D
Elimination method means you're essentially. "subtracting" one equation from another.
x-y=17
- x+y=-1
---------
-2y=18
Now we'll solve x+y=-1 and -2y=18 separately.
-2y=18
Divide both sides by -2.
y=-9
x-9=-1
Add 9 to both sides.
x=8
The solutions are x=8 and y=-9, or (8,-9).
Answer:
351
Step-by-step explanation:
First you have to find the areas of the two parts, for the herbs its 135ft to get that you need to look at the large 18ft on the left side, and the 9 feet on the right side, 18-9=9 and then multiply by the 15 on the top. 9x15=135 for the vegetables you multiply 9 by 24 9x24= 216 add the 135 to get 351
