Can you take the quantity [ x + y ] and square it ?
Can you take the quantity [ x + 2y ] and square it ?
Then you should have no trouble with the square of (.9x + .8y) .
The square of any binomial (expression with 2 terms) is
(square of the first term)
+ (square of the second term)
+ 2 times (product of the terms) .
X-4+x=20
2x=20+4
2x=24
X=12
Number is 12 because 12-4 is 8 and 8+12 is 20
A because I did the work and I just know its right
Answer:
Step-by-step explanation:
Problem One
19 + 2*ln(x) = 25 Subtract 19 from both sides
19 - 19 + 2ln(x) = 25 - 19 Combine
2* ln(x) = 6 Divide by 2
ln(x) = 3 Take the inverse log
e^(ln(x)) = e^3 Reduce
x = 20.09
Problem 2
Getting this to graph in Desmos can be a bit of trouble. The correct format is y = abs(x^2 - 3x + 1). Knowing about abs and getting the quadratic to work are two separate [and difficult] problems.
The graph for this is below.
The answers (according to Desmos) are (2,1) and (3.4, 2.4). I think you should include D but that is a matter of opinion. I think it's a typo. Whoever made the question up may actually get that answer.
