X-y=3=>x=3+y
X+2y=-6
=========
3+y+2y=-6
3+3y=-6
3y=-6-3
3y=-9
y=-3
X+2y=-6
X+2(-3)=-6
X-6=-6
X=0
under a rotation about the origin of 180°
a point (x, y ) → (- x, - y )
hence D is correct, both the x and y coordinates of the points on ΔA'B'C' have opposite signs from the corresponding points on ΔABC
You know the following information:
1. The amount of money (in dollars) earned last year was:
2. The amount of money (in dollars) earned this year, is:
Then, to estimate the sum (the total amount of money the Software Company earned in those two years, you can round the numbers to the nearest billion.
Having:
You need to look at the digit located in the Hundred millions place. Notice that this is:
Then, since:
You need can't round up. Then:
Now, having:
You can identify that the digit in the Hundred millions place is
Therefore:
Now you can add the numbers rounded:
Hence, the answer is: Option B.
Answer:
6/24= 3/12 = 1/4= 25%
Step-by-step explanation:
add 6+6+12 = 24. 6 small dogs so 6/24 and simplify
F(x) = a(x-h)²<span> + k
</span><span><u>Given that the vertex is (-3 -6):</u>
</span>f(x) = a(x + 3)² -6
<span>
<u>Given that it passes through (0.0), find a:</u>
a(0 + 3)</span>² - 6 = 0
<span>
9a - 6 = 0
9a = 6
a = 6/9 =2/3
<u>So the equation is :</u>
</span>f(x) = 2/3(x + 3)² -6
<span>
<u>Write the equation in standard form:</u>
</span>f(x) = 2/3(x² + 6x + 9) - 6
f(x) = 2/3x² + 4x + 6 - 6
f(x) = 2/3x² + 4x
<span>
Answer: </span>f(x) = 2/3x² + 4x<span>
</span>
