Is 6/2(2+1) 1 or 9? I will tell you why it should be one:
6/2a = 3/a. Let a = 2+1.
Answer:
(3,0)
Step-by-step explanation:
The <u>solution</u> of a system of equations is <u>where they meet on a graph.</u>
The two order pairs meet at (3,0)
X = t +4
y = t^2
Rewrite the first equation:
x = t+4
Subtract 4 from each side:
t = x-4
Replace t in the 2nd equation with the rewritten equation:
y = x-4^2
Rewrite x-4^2 as (x-4)(x-4)
Use FOIL to get y = x^2-8x+16
The answer is D.
The answer is A. If you translate the triangle 10 units up and reflect it over the y-axis, the triangle will be on top of the other.
Answer:
45, 117,18
Step-by-step explanation:
The ratio of the three angles are
5:13:2
Multiply that by x
5x 13x 2x
The sum of the three angles is equal to 180.
5x+13x+2x = 180
Combine like terms
20x = 180
Divide by 20
20x/20 = 180/20
x = 9
The angles are
5x = 5*9 = 45
13x = 13*9 = 117
2x=2*9 = 18
