Answer:
18
Step-by-step explanation:
Solve the separate part of the equation first
6(4) 6(-2) would equal 24-12
Add it back in to get: 10 - 4 + 24 - 12
-4-12 and 10+24 are the like terms so
10+24 = 34 and -4-12 = -16
Equation in the end: 34-16
Simplify that to: 34-16 = 18
2x²+6x-8+x+3 in standard form is 2x²+7x-5.
Hope this Helps!
First, add 84 to both sides, to isolate the exponential function.
Then, take the logarithm of both sides:
(2x+3)*log 5 = log 84
Solving for 2x+3, we get log 84 - log 5, and so
2x = -3 + log 84 - log 5. Dividing both sides by -3, we obtain the final answer:
-3 + log 84 - log 5

Answer:
This is a function
Step-by-step explanation:
The vertical line test is a test where you take a straight vertical line and move it from right to left. If during the test, the line touches two points at the same time, it's not a function. In this case, it is a function since it passes the vertical line test.
Answer:
The answer is below
Step-by-step explanation:
The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is given by:
Point J is at (-3, 3), point K is at (4, 3) and point L is at (1, -1). Hence:
The distance between K and L = KL = 
The distance between J and L = JL = 
The distance between K and J = JK = 
Therefore, the perimeter of triangle JKL is:
Perimeter = KL + JL + JK = 5 + 4√2 + 7 = 17.66 units
