Complete Question:
On Monday, Sarah has to meet her friend at the park after school. The distance from her house to school is 2x + 5. The distance from school to the park is x. If the total distance she walks that day is 10x + 9, how far is it from the park back to her house?
Answer:
[tex] = 7x + 4 [/tex]
Step-by-step explanation:
Distance from her house to school = 2x + 5
Distance from school to park = x
Total distance walked that day including distance from the park back to her house = 10x + 9
Distance back to her house = total distance walked - (distance form her house to school + distance from school to park)
= [tex] (10x + 9) - ((2x + 5) + (x)) [/tex]
[tex] = (10x + 9) - (2x + 5 + x) [/tex]
[tex] = (10x + 9) - (3x + 5) [/tex]
[tex] = 10x + 9 - 3x - 5 [/tex]
Combine like terms
[tex] = 10x - 3x + 9 - 5 [/tex]
[tex] = 7x + 4 [/tex]

Subtract the sides of the equation minus 2x :
[tex]3y = 11 - 2x[/tex]
Divided the sides of the equation by 3 :
[tex] \frac{3}{3}y = \frac{ - 2x + 11}{3} \\ \\ y = - \frac{2}{3}x + \frac{11}{3} [/tex]

help find the equation of the tangent line please (calculus)
Answers
The tangent line to f(x) at x = c has slope equal to the derivative at c, or f'(c).
We have
f(x) = 3 - 2 x + 7 x²
so that
f'(x) = -2 + 14 x
The slope is 5 for
-2 + 14 x = 5 ==> 14 x = 7 ==> x = 1/2
Now, f (1/2) = 15/4, so the tangent line has equation
y - 15/4 = 5 (x - 1/2) ==> y = 5 x + 5/4

Answers
The supplementary angle pairs are: angles 4 and 5
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. Which means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
We know that Two Angles are Supplementary when they add up to 180 degrees.
In the given diagram , the pair of angles must be supplementary that are:
angles 1 and 8
angles 2 and 7
angles 4 and 5
angles 3 and 4

How to find equation of line from two points?The equation of line from two points is given by
[tex]y -y_{1} = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } (x-x_{1} )[/tex]
According to the given question
We have two points (3,1) and (5, -4)
Therefore, the equation of line which passes through the points (3,1) and (5, -4) is given by
[tex](y -1)=\frac{-4-1}{5-3} (x-3)[/tex]
⇒[tex](y-1)=\frac{-5}{2}(x-3)[/tex]
⇒[tex]y -1=\frac{-5}{2}x+\frac{15}{2}[/tex]
⇒[tex]y =-\frac{5}{2} x+\frac{15}{2} +1[/tex]
⇒[tex]y = -\frac{5}{2}x+\frac{17}{2}[/tex]
Hence, the equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .

Consider a communication source that transmits packets containing digitized speech. After each transmission, the receiver sends a message indicating whether the transmission was successful or unsuccessful. If a transmission is unsuccessful, the packet is resent. Suppose a voice packet can be transmitted a maximum of 8 times. Assuming that the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p, determine the probability mass function of the number of times a packet is transmitted.
Answers
Answer:
The probability mass function is
[tex]F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }[/tex]
Step-by-step explanation:
From the question we are told that
The maximum transmission time is [tex]n = 8[/tex]
Generally the number of times a packet is transmitted follows a binomial distribution given that the the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p
Generally the probability mass function is mathematically represented as
[tex]F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }[/tex]
