A student says that the equation of the line that passes through the points (6, 1) and (6, 3) cannot
be written. Explain your thoughts on this statement. (Hint: examine the coordinates of the two
points carefully. What do you notice?)
PLEASE HELP ME
Answer:
Your points have the same x coordinates....this means that u have a vertical line which has an undefined slope. Being that the slope is undefined, you cannot write the vertical line in slope intercept or point slope form. Im not full sure this is right but maybe this will help understand something
Step-by-step explanation:
Answer:
The line has same x- values and different y- values.
It can have an equation, which is:
x = 6For any value of y, the line has x- value of 6.

7. If F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5)=-2, gʻ(5) = 6.. Find F'(5)
Step-by-step explanation:
I'm going to lay this out in a chart so it's a little easier to see:
F(x) = f(g(x))
x | f (x) | f ' (x) | g (x) | g ' (x)
--------------------------------------
-2 | 8 | 4 |
5 | | 3 | -2 | 6
Remember the chain rule, which says
(f (g (x))) ' = g ' (x) f ' (g (x))
When they ask for F ' (5), they are asking for (f (g (x))) ' when x = 5.
Using the chain rule, that's
F ' (5) = g ' (5) f ' (g (5))
We can simplify using the numbers provided.
F ' (5) = (6) f ' (-2)
F ' (5) = (6) (4)
F ' (5) = 24
I hope that helps!
The required simplified solution of the F'(5) is 24
Given that,
F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5)=-2, gʻ(5) = 6..
To determine F'(5),
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
F(x) = f(g(x))
Now,
F'(x) = (f (g (x))) '
Following the chain rule
F'(x) = g ' (x) f ' (g (x))
Now,
x = 5
F'(5) = g'(5)f'(g(5))
substitute the value in the above equation,
F'(5) = 6 × f'(-2)
F'(5) = 6 × 4
F'(5) = 24
Thus, the required simplified solution of the F'(5) is 24.

At Chase Bank, you earned $50 in interest last year. If the interest rate is 4.5% and
your money was in the account for one year, what was your principal deposit, rounded to
the nearest dollar?
Answer:
$1,111
Step-by-step explanation:
Let x = principal amount
x multiplied by 1.045 will equal the final amount
Since 50 was earned, x + 50 will also equal the final amount
1.045x = x + 50
Let's move the x terms to left side by subtracting both sides by x
1.045x = x + 50
- x - x
0.045x = 50
Divide both sides by 0.045 to isolate the x variable
0.045x/50 = 50/50
x = 1,111.111111111
Write in standard form.
y^2+14y-5x+64=0

[tex] \hookrightarrow \: 5x = {y}^{2} + 14y + 49 + 15[/tex]
[tex] \hookrightarrow \: 5x = (y + 7) {}^{2} + 15[/tex]
[tex] \hookrightarrow \: x = \dfrac{(y + 7) {}^{2} + 15 }{5} [/tex]
[tex] \hookrightarrow \: x = \dfrac{1}{5} (y + 7) {}^{2} + 3[/tex]
therefore, the correct option is B
Answer:
x = (1/5)(y + 7)² + 3
Step-by-step explanation:
Given that,
→ y² + 14y - 5x + 64 = 0
Let's find the required solution,
→ y² + 14y - 5x + 64 = 0
→ 5x = y² + 14y + 64
→ 5x = y² +14y +49 + 15
→ 5x = (y + 7)² + 15
→ x = [(y + 7)² + 15]/5
→ [x = (1/5)(y + 7)² + 3]
Hence, it is the correct answer.

A long distance runner does a first lap around a track in exactly 50 seconds. As she tires each subsequent lap takes 20% longer than the previous one. How long does she take to run 3 laps?
9514 1404 393
Answer:
182 seconds, or 3 minutes 2 seconds
Step-by-step explanation:
The second lap takes ...
(50 s)(1 +20%) = (50 s)(1.2) = 60 s
The third lap takes ...
(60 s)(1.2) = 72 s
The three laps take 50 +60 +72 = 182 seconds, or 3 minutes 2 seconds.
