Answer:
x = -1 ± √6 / 5
Step-by-step explanation:
Solve 
+ 2x = 1
move 1 to the left side of the equation by subtracting it from both sides.
+ 2x - 1 = 0
Use the quadratic formula to find the solutions.
-b± 
/ 2a
Substitute the values a = 5 , b = 2, and c = -1 into the quadratic formula and solve for x
-2±
/ 2 ⋅ 5
Simplify.
x = -2 ± 2 
/ 10
x = -1 ± / 5
Exact Form:
x = -1 ± / 5
Answer:
51 students.
Step-by-step explanation:
First you need to establish a rate 6/100+3/50
8*100=800 6*8=48
3/50
850-800=50 3/50
48+3=51
Answer:
The following numbers ARE functions:
2, 3, 6, 7, 9, 12
Step-by-step explanation:
A function is only possible if the x values have NO REPEATING NUMBER!!!
Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.
<u>Question 1</u> has the 8 and 4 with 2 numbers.
<u>Question 4</u> the 3 repeating. (There are 2 dots over the 3)
<u>Question 5</u> has numbers 1 and 5 repeating many times
<u>Question 8</u> numbers 1 and 2 are repeated twice
<u>Question 10</u> number 3 repeats twice
<u>Question 11</u> has the 1 repeated
Yes, these are equivalent
Answer:
dy/dx=8
Step-by-step explanation:
note this differentiating a constant you get zero for that of a function like 8x you would use the index or power of x to multiply the coefficient of the x after substrate 1 from the power of the x putting that in writing for the above question we get
y'=dy/dx=(8*1)x^(1-1) - 0
y'=dy/dx=8x^0
y'=dy/dx=8
