The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
Answer:
The first question:
x = -1
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-x - 1 = -1 • (x + 1)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-1 = 0
Add 1 to both sides of the equation :
-x = 1
Multiply both sides of the equation by (-1) : x = -1
One solution was found :
x = -1

Step-by-step explanation:
A linear equation in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula using any 2 points from the table.
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (10, - 1) and (x₂, y₂ ) = (5,2)
m =
=
= - 
Note the point (0, 5) is on the y- axis → c = 5
y = -
x + 5 ← equation representing the function
