You're meant to make one side of the equation equal 0.
For example, the first problem is
+ 9k = -7
You'd add 7 to both sides, leaving you with
+ 9k +7 =0
And I assume you know how to factor??
Answer:
V≈4.19ft³
Step-by-step explanation:
The volume of a sphere with a radius of 1 foot is 4.19ft³.
In order to find this:
V=4
3πr3=4
3·π·13≈4.18879ft³
Answer:
Step-by-step explanation:
We are given a system of equation:
To find a solution to the given system, we follow the given steps.
1. Subtracting second equation from first and third equation, we get:
2. After eliminating z to obtain two equations in two variable, we observe that the two equations obtained were same.
So we have three equations that will all graph in the same plane.
Thus, there are infinite number of solution to the given system of equation.
We can write the values of x and y in the form of z:
There's a lot of different approaches to this question, but the easiest one I see is this:
If a chord goes through the center of the circle, it is a diameter. That's 180 degrees we don't have to worry about. 47 is an inscribed angle, so we can multiply it by two to get 94 degrees. Subtract 94 from 180 to get 86.
See y? It's also an inscribed angle. To get it, we just take the 86 we just found for the remaining arc and divide by two.
The measure of y is 43.
Answer:
i got x=-135
Step-by-step explanation:
lets solve!
first remove the parentheses= x-1.2x=27
second you collect like terms= -0.2x=27
last divide both sides by -.02 = x=-135
hope this helps you!! :)
