Answer:
I just took the test, it's 1 and 3
Step-by-step explanation:
Hey there,
To find the value of x we can take the two, CD or DE and set them equal to CE.
First step is set the lines equal to each other:
Now we combine like terms:
Then we subtract 7x from both sides:
Add 6 to both sides:
Lastly we divide both sides by 2:
So the value of x would have to be 5.
Hope I helped,

For this case we have the following equation:
y = 3619000 (2.7) ^ 0.009t
We must evaluate the equation for the year 2000.
Therefore, we must replace the following value of t:
t = 2000 - 1994
t = 6
Substituting we have:
y = 3619000 (2.7) ^ (0.009 * 6)
y = 3818407.078
Round to the nearest ten thousand:
y = 3820000
Answer:
3820000 residents are living in that city in 2000

For these lines, let

.

And for these, let

.
Now,

The vertices of

in the x-y plane are (0, 2), (2/3, 10/3), (2, 2), and (4/3, 2/3). Applying

to each of these yields, respectively, (2, 2), (2, 4), (-2, 4), and (-2, 2), which are the vertices of a rectangle whose sides are parallel to the u-v plane.
3x² - 7x - 8 = 0
We're asked about square roots so we won't try to factor; we'll go right for the quadratic formula,
x = ( 7 ± √(7² - 4(3)(-8)) )/(2(3)) = (7 ± √(49+96))/6 = 7/6 ± √145/6
145 = 5×29, so no square factors. The positive difference is
d = (7/6 + √145/6) - (7/6 - √145/6) = 2√145/6 = √145/3
so m=145, n=3 for a sum of
Answer: 148
