Answer:
Step-by-step explanation:
I believe that there was a typo in this question
Unfortunately, there are no roots of this equation without one of two things:
1. Another equation, and you could solve for the roots in a system of equations
2. The value of y is actually supposed to be 0
In the second case, you would solve it like this:
-3x = 0
factor out x
x(x-3) = 0
x = 0, x = 3
Answer:
B
Step-by-step explanation:
toookt the test dude
Answer:
It already is in standard form
y=(x-2)(x-4) :)
Step-by-step explanation:
Okay, so there are nickels and pennies in this jar.
So, let's call the number of pennies X
Since there are 161 coins altogether, the number of nickels is (161 - X)
So now we solve the equation:
.01X + .05(161 - X) = 3.09
.01X + 8.05 - .05X = 3. 09
4.96 = .04X
124 = X
So, there are 124 pennies
Therefore, there are 161 - 124 = 37 nickels
Let's check our answer:
124 x .01 + 37x .05 = 1.24 + 1.85 = 3.09
It works!
Answer:
A. AB
Step-by-step explanation:
Given that the musical instrument has a shape of ∆ABC, we can determine the shortest side that would be parallel to the ground by comparison of the 3 angles of the triangle corresponding to each side that is opposite each of them.
What this means is that, the larger angle would have the largest side opposite it. The medium angle will have medium length side opposite it, while the smallest angle will have the smallest side opposite it.
m < A = 59°
m < C = 57°
m < C = 180 - (59+57) (sum of angles in a triangle)
m < C = 64°
The smallest angle out of the three angles is angle C = 57°.
The side opposite it, is side AB.
Side AB is the shortest side of ∆ABC.
Therefore, AB should be parallel to the ground.
