342/18 18 x 10= 180 342 - 180= 162 18 x 9= 90 + 72= 162 10+9= 19 The answer is 19
If the original investment doubled in 10 years, then double the investment
will double again in the next 10 years. Thus, in <u>20 years</u>, the original sum
would have increased fourfold.
The typical window is about 2.5 - 3 feet long
This parabola is looking up, so it can be C. or D.
We can take a point like vertex (-2, -3) and check it.
<span>
D. y=x² + 4x + 1
</span>-3 =(-2)² + 4(-2)+1
-3 = 4 - 8 +1
-3 = -3 True.
C. <span>y=2x² + 4x + 1
</span> -3 = 2(-2)² +4(-2)+ 1
-3= 8 -8+1
-3 = 1 False
So, correct answer is D. y=x² + 4x + 1
12y - 7x = 5......(1 , ?)....when x = 1....so we sub 1 in for x
12y - 7(1) = 5
12y - 7 = 5
12y = 5 + 7
12y = 12
y = 12/12
y = 1........so ur y value is 1....and ur ordered pair is (1,1) <==
