Answer:
Step-by-step explanation:
y - y1 = m (x - x1) the slope m = 1 (x1, y1) = (-7, -1)
y - -1 = 1 (x - -7)
y + 1 = 1 (x + 7)
y = x +6

Anders flips two coins. Explain why the probability of two heads is 1/4
Answer:
If anders flips one coin, he has a 1/2 chance of heads.
if he flips two, he has to get to heads, which the chances are 1/2 and 1/2
So multiply 1/2*1/2
you get 1/4
Three men working together can finish a house repair job in 10 days. How manydays will 5 men working at the same rate finish the same job? *
Answer:
17 days
Step-by-step explanation:
Number of days in which 3 men can finish a house repair job = 10 days
Number of days in which 1 man can finish a house repair job = [tex]\frac{10}{3}[/tex] days
Therefore,
Number of days in which 5 men can finish a house repair job = Number of days in which 1 man can finish a house repair job × 5
[tex]=\frac{10}{3}(5)=\frac{50}{3}=16.6[/tex] ≈ 17 days

Answer:
The length of the side TU is approximately 29.9 feet long.
Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(42^{o})}{20}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} = \frac{20}{sin(42^{o})}[/tex] ⇒ [tex]x=\frac{20*sin(90^o)}{sin(42^{o})}[/tex] ⇒ [tex]x=29.9ft.[/tex]

Line parallel to y= -2 + 7
Answer:
So, equation y=7 is parallel to x-axis. A line parallel to X axis. x axis because it is the same thing as y=0x+7 or y=7, therefore y intercept is 7 and slope is 0.
Step-by-step explanation:
Select the correct answer.
Find the solution(s) for x in the equation below.
x(x - 1) = 42
А. x = -7; x = -6
B. x = 7; x = 6
C. x = 7; x = -6
D. x = 6
Answer:
7 and -6 (corresponding to Answer C)
Step-by-step explanation:
Solve x(x - 1) = 42 for x.
To do this, first perform the indicated multiplication and then rearrange the terms in standard quadratic function order:
x^2 - x - 42 = 0
Factoring yields (x - 7)(x + 6) = 0,
leadng to roots 7 and -6 (corresponding to Answer C)

(50 POINTS) Math Inverse Functions please help
Answer:
See below.
Step-by-step explanation:
An inverse function has the x and y coordinates switched. For example, if a function has point (1, 3), then the inverse function has point (3, 1).
Let's find the ordered pairs of the inverse function. We take all the ordered pairs of the original function:
(1, 3), (7, 4), (8, 6), (9, y)
Now we switch x and y in each ordered pair to come up with the inverse function.
The inverse function has these ordered pairs:
(3, 1), (4, 7), (6, 8), (y, 9)
For a relation to be a function, a value used as an x-coordinate can appear only once.
The last ordered pair is (y, 9). For the inverse relation to be a function, y cannot be 3, 4, or 6.
Answer:
inverse of ordered pair (1,3),(7,4),(8,6)and (9,y)
is (3,1),(4,7),(6,8)and(y,9)
restriction is
y≠3,4&8
HELP PLEASE!! Identify Structure What linear expression would you need to subtract from (5x+3) to have a difference of −x ?
Answer:
Expression that is to be deducted will be (6x + 3).
Step-by-step explanation:
Let the linear expression that is to be subtracted from the given expression (5x + 3) is (ax + b).
After subtracting (ax + b) from (5x + 3) the remainder is (-x)
(5x + 3) - (ax + b) = -x
(5x - ax) + (3 - b) = -x
(5 - a)x + (3 - b) = -x
By comparing coefficients,
(5 - a) = -1
a = 5 + 1
a = 6
(3 - b) = 0
b = 3
Therefore, expression that is to be deducted from (5x + 3) will be (6x + 3).
What are the two solutions to f(x)=g(x) when f(x)=x^2+3 and g(x)=-x+9

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Starting from a full tank, can Diego's family drive the car for 14 days without the warning light coming on? Explain your reasoning.
Answer:
20 days
Step-by-step explanation:
Subtract 1.5 gallons from 14 gallons to obtain the number of days the car will run without the warning light going on: 12.5 gallons.
Dividing this result by 0.6 gallons/day, we get
12.5 gal
------------------- = 20.82 days. Round this down to 20 days. (We're not
0.6 gal/day dealing in partial days.)

A fair coin is tossed 14 times. What is the probability of obtaining exactly 1 head? (Enter your answer as a reduced fraction or a decimal rounded to 4 places.)
Answer:
0.0009 probability of obtaining exactly 1 head
Step-by-step explanation:
For each toss, there are only two possible outcomes. Either it is a head, or it is not. The probability of a toss being a head is independent of any other toss. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A fair coin is tossed 14 times.
Fair coin means that it is equally as likely to be heads or tails, so [tex]p = 0.5[/tex]
14 times means that [tex]n = 14[/tex]
What is the probability of obtaining exactly 1 head?
This is P(X = 1).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{14,1}.(0.5)^{1}.(0.5)^{13} = 0.0009[/tex]
0.0009 probability of obtaining exactly 1 head
Which statement is true about this set of data?
43, 50, 60, 36, 47, 50, 52, 78
A. The range is 31.
B. The mode is 78
C. The median is 51
D. The mean is 52.
Answer:
D. The mean is 52.
Step-by-step explanation:
In order to find the mean, you add up all of the numbers and then divide that answer by how many numbers there are.
43+50+60+36+47+52+78=416
416/8=52
Answer:
D. The mean is 52.
Step-by-step explanation:
Add all numbers in the set:
36+47+50+50+52+60+78= 416
Now, divide the sum by how many numbers are in the set; in this case, there are 8 numbers so:
416÷ 8= 52
