7x + 17 = 7x - 17
7x + 17 - 7x = 7x - 17 - 7x
17 = -17
Inconsistent: for no value of x is the above equation true. 17 ≠ -17.
Hope this helps! :)
the center is at the origin of a coordinate system and the foci are on the y-axis, then the foci are symmetric about the origin.
The hyperbola focus F1 is 46 feet above the vertex of the parabola and the hyperbola focus F2 is 6 ft above the parabola's vertex. Then the distance F1F2 is 46-6=40 ft.
In terms of hyperbola, F1F2=2c, c=20.
The vertex of the hyperba is 2 ft below focus F1, then in terms of hyperbola c-a=2 and a=c-2=18 ft.
Use formula c^2=a^2+b^2c

The branches of hyperbola go in y-direction, so the equation of hyperbola is

The relationship between 1’s in the value of 911, 147, 835
shows their numerical order in the number. In which to further elaborate we
shall break down the number into its expanded form and word form:
<span><span>1. </span>900, 000,
000 = nine hundred million</span>
10, 000, 000 = ten million
1, 000, 000 = one million
100, 000 = one hundred thousand
40, 000 = forty thousand
7, 000 = seven thousand
800 = eight hundred
30 = thirty
5 = five
<span><span>2. </span><span> Nine hundred eleven million one hundred
forty-seven thousand eight hundred and thirty five. </span></span>
The remaining number of flires that Linda still not posted is 40.
According to the given question.
The total number of fliers Linda have = 84
Fraction of fliers Linda posted = 1/3
And, fraction of fliers Linda posted second time from the remaning fliers = 2/7
Now,
1/3 of 84 fliers = 1/3 × 84 = 28
So, the number of fliers are left with Linda after first posting = 84 - 28 = 56
Again she posted 2/7 fliers. The number of flires Linda posted second time is given by
⇒ 2/7 × 56 = 16
Thereore, the number of fliers that Lindna still not posted = 56 - 16 = 40
Hence, Linda still not posted 40 fliers.
