Remember you can do anything to an equation as long as you do it to both sides
alrighty
distribute, rmember that a(b+c)=ab+ac
-3x-9=-3x-3-5
combine like terms
-3x-9=-3x-8
add 3x to both sides
-9=-8
false
no solution
answer is no solution
One time around the origin of a coordinate plane is 360 degrees. So in order to get to 453, we will go all the way around once, and then keep going til we get to 453. 453-360 = 93. That means that the coterminal angle is 93. It's terminal side is in Q2. If we are looking to find the reference angle, it is 180-93 which is 87. Usually these are presented in the same chapter in math, if not in the same section.
X would equal 48°
Step-by-step explanation:
59°-11°= 48° (x)
Hello from MrBillDoesMath!
Answer: NO points of intersection. The two lines are parallel
Discussion:
Rewrite the equations so the variables and constants line up vertically
x - 2y + 8 = 0
x - 2y -6 = 0 (I added "x" to both sides of the second equation)
Subtract the bottom equation from the the top one:
(x - 2y + 8) - ( x - 2y -6) = 0 or
x - 2y + 8 - x + 2y + 6 = 0 or
(x-x) + (-2y +2y) + (8 + 6) = 0 or
0 + 0 + 14 = 0
14 = 0 !
No solution exists. (Another approach: What is the slope of each line? Hint: 1/2. Since the slopes are the same the lines are parallel and have no points of intersection)
Thank you,
MrB
Answer:
Step-by-step explanation:
P=(3.14)(d) diameter divided by 2 equals radius
P=(3.14)(13)
P=40.82
A=(3.14)(6.5)(6.5)
A=(3.14)(42.25)
A=132.665
