a babysitter charges 9 dollars each hour she works plus a travel allowance of 5 dollars for each job. write an equation that relates the number of hours. the babysitter worked at a job for which she charged 77 dollars. how many hours did she work?
Answer:
y=9x +5 , 8 hours
Step-by-step explanation:
9 dollars per hour = 9x
travel allowance = 5
y = 9x + 5
77 = 9x + 5
77 = 9x +5
-5 -5
-----------------
72= 9x
72/9 = x
x= 8

Answer:
y= -1/2 + 2
Step-by-step explanation:
To find m or the slope you need to find 2 locations that the line intercepts a point on the graph. I used (0,2) and (2,1).
Then you find the difference of the x and y coordinates. (x,y)
X-coordinates: 0 and 2. 0 - 2 = -2
Y-coordinates: 2 and 1. 2 - 1 = 1
A slope fraction is the difference of y over the difference of x coordinates. It would be written as 1/-2 or -1/2. m= -1/2
To find the b value, just look at the y-intercept or where the line intercepts the y-axis. Which is at (0,2). So b=2

There are two types of cellular phones, handheld phones (H)that you carry and monile phones (M) that are mounted invehicles. Phone calls can be classified by the travelingspeed of the user as fast (F) or slow (W). The probabilitymodel for this experiment has the following information: P[F] =0.5, P[HF] = 0.2, P[MW] = 0.1. What is the sample space ofthe experiment? Calculate the followng probabilites:a) P[W]b) P[MF]c) P[H]
Answer:
Explained below.
Step-by-step explanation:
(1)
Sample space is a set of all possible outcomes of an experiment.
The sample space in this case is:
S = {HF, HW, MF, MW}
(a)
Compute the value of P (W) as follows:
P (F) + P (W) = 1
P (W) = 1 - P (F)
P (W) = 1 - 0.50
P (W) = 0.50
(b)
Compute the value of P (MF) as follows:
P (HF) + P (MF) = P (F)
P (MF) = P (F) - P (HF)
P (MF) = 0.50 - 0.20
P (MF) = 0.30
(c)
Compute the value of P (M) as follows:
P (M) = P (MF) + P (MW)
P (M) = 0.30 + 0.10
P (M) = 0.40
Compute the value of P (H) as follows:
P (H) + P (M) = 1
P (H) = 1 - P (M)
P (H) = 1 - 0.40
P (H) = 0.60

Over the last week, the daily low temperatures in degrees Fahrenheit have been −2, 6.9, 17 1 2 , −5.1, 24, − 1 4 , and 1.45. List these numbers in order from greatest to least.
Answer:
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
Step-by-step explanation:
Given the following temperature values :
2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.
Ordering the values above from greatest to least ; (descending order)
Expressing all temperature values in the same format :
Let's make sure all values are in decimal to make comparison easier :
2.0
6.9
17 1/2 = 35/2 = 17.5
-5.1
24.0
-1/4 = - 0.25
1.45
We begin from the temperature value which is highest :
24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1
Hence ;
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

Answer: y = -2x² + 920x - 84168
suppose: the equation of the parabola is y = ax² + bx + c
because the parabola passes through (126,0); (134,3200); (334,0)
=> we have the equations:
126².a + 126b + c = 0
134².a + 134b + c = 3200
334². a + 334b + c = 0
⇒ a = -2
b = 920
c = -84168
=> the equation of the parabola is y = -2x² + 920x - 84168

Which equation best describes the line in the graph?
Answer:b
Step-by-step explanation:
Give brainliest
Answer:
B
Step-by-step explanation:
The question is looking for an equation in slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept is +4, which all of the answers show, so you must find the slope.
The slope is the change in y over change in x, more commonly referred to as rise over run. So count how many units the graph changes vertically and horizontally, in this case, 1 up and 2 right, so the slope is equal to 1/2. If you have a graph where the line shifts up and left, or down and right, then the slope is negative. Additionally, one way to visually check your work is to remember slopes equal to less than -1 or greater than +1 will be steeper while fraction slopes will make the slope flatter; basically the closer to zero the less steep.

Nicolas sold 86 newspapers on Monday 79 on Tuesday and 68 on Wednesday and 83 on Friday how many newspapers did Nicholas sell on Thursday if he sold a total of 391 in five days?
Define a variable, write an equation, then solve.
Answer:
75
Step-by-step explanation:
86+79+68+83=316
391-316=75
Answer:
75 newspapers
Step-by-step explanation:
391 is equal to the combination of all the newspapers Nicholas sold over those 5 days. This can be written as an equation:
391 = 86 + 79 + 68 + 83 + x
x represents the number of newspapers Nicholas sold on Thursday.
Now let's solve for x:
First, combine like terms:
391 = 316 + x
now subtract 316 from both sides to isolate x:
391 - 316 = 316 - 316 + x
75 = x
Nicholas sold 75 newspapers on Thursday.

what is the vaule 7 to the 6 power
Answer:
117,649
Step-by-step explanation:
Good luck! <3
Answer:
7 to the 6th power is conventionally written as 76, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 7^6.
76 stands for the mathematical operation exponentiation of seven by the power of six.
As the exponent is a positive integer, exponentiation means a repeated multiplication:
The exponent of the number 7, 6, also called index or power, denotes how many times to multiply the base (7).
Thus, we can answer what is 7 to the 6th power as
7 to the power of 6 = 76 = 117649.

Yes, he has enough money to get his things.
Step-by-step explanation:
3 (the amount of grass seed bags he's buying) x 23 (how many dollars it costs) = 69
3 (the amount of flower pots he's buying) x 15 (how many dollars it costs) = 45
69 + 45 = 114
