Answer:
the points are :
(0,-1)
(0,0)
(-1,3)
(If you are using MathsWatch) For this question the triangle gets smaller so i'm not sure why it says Enlarge the triangle.
Answer:
Step-by-step explanation:
Take natural log of both sides first.
Taking the natural log of both sides allows you to bring down the powers.
I'm going to differentiate both sides using the power rule.
Now recall (ln(x))'=(x)'/x=1/x while (ln(y))'=(y)'/y=y'/y.
Simplifying a bit:
Now going to gather my terms with y' on one side while gathering other terms without y' on the opposing side.
Subtracting y'ln(x) and ln(y) on both sides gives:
Now I'm going to factor out the y' on the right hand side:
Now we get to get y' by itself by dividing both sides by (-ln(x)+x/y):
Now this looks nasty to write mini-fractions inside a bigger fraction.
So we are going to multiply top and bottom by xy giving us:
Answer:
yes they are the same
Step-by-step explanation:
Equations don't equal numbers.
Sometimes their solutions, if they have one, do.
Here are three equations whose solutions are 36 :
x + 15 = 51
x/3 = 12
x² - 72x + 1,296 = 0
Step-by-step explanation:
-5x+8y=-4
6x-8y=-12 8y and 8x cancel out
x=-16
To solve for y, substitute x=-16 back into the first equation
-5(-16)+8y=-4
80+8y=-4
8y=-84
y=-10.5
