b
Write the slope-intercept form of the equation of each line.
Step-by-step explanation:
9.
the first we see when going from left to right : the line goes down, so it has a negative slope (factor of x).
then we look at the y-intercept (the point where the line crosses the y-axis) : negative y and around -5.
with all that we have eliminated B and D.
and not only does the line go down, it goes sharply down. so, the absolute value of the slope must be bigger.
therefore, C is the right answer.
and a quick check confirms, as the slope -10/3 means that for a change of x by +3 units causes y to change by -10, and that is what we are seeing on the chart.
at x = -3 it looks like y is about +5.
and at x = 0 (change by +3) it looks like y is about -5 (change by -10).
10.
the y-intercept does not give us a clue here, it is 1 for all 4 options, and the graph confirms it.
but this line goes up, so the slope is positive.
it is rather "flat" and by far not even diagonally, so the absolute value of the slope must be a small value (much smaller than 1, as a slope of 1 means "diagonally").
therefore, D is the right answer.
a quick check confirms, as the slope 1/5 means that for a change in x by +5 would lead to a change in y by +1.
and that is what we are seeking on the chart.
at x = -5 it looks like y is about 0.
at x = 0 (change by +5) it looks like y is about +1 (change by +1) - the y-intercept.
Solve for b.
5b = 85
Answer:
b = 17 t = 12
Step-by-step explanation:
5b = 85
5b/5 = 85/5
b = 17
t/3 = 4
t/3 x 3 = 4 x 3
t = 12

Flaws in a certain type of drapery material appear on the average of one in 150 square feet. If we assume a Poisson distribution, find the probability of at least one flaw appearing in 300 square feet.
Using the Poisson distribution, it is found that there is a 0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.Flaws in a certain type of drapery material appear on the average of one in 150 square feet, hence, considering 300 square feet, the mean is of:
[tex]\mu = \frac{300}{150} \times 1 = 2[/tex]
The probability of at least one flaw appearing in 300 square feet is given by:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-2}2^{0}}{(0)!} = 0.1353[/tex]
Then:
[tex]P(X \geq 1) = 1 - 0.1353 = 0.8647[/tex]
0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.

Felicity baby sat 2 hours each night for 10 nights. She earned a total of 180 babysitting. Felicity wants to calculate her hourly rate. How much did Felicity earn per hour babysitting?
Answer:
$9 per hour
Step-by-step explanation:
Total number of hours = hours each night x number of nights
⇒ Total number of hours = 2 x 10 = 20 hours
Hourly rate = total earned ÷ total number of hours
⇒ Hourly rate= 180 ÷ 20 = 9
Therefore, hourly rate = $9 per hour
Answer:
9 dollars per hour
Step-by-step explanation:
First determine the total number of hours
2 hours * 10 nights = 20 total hours
Divide the total amount paid by the total hours to get the rate
180 /20 = 9
She is paid 9 dollars per hour

Y’all I really don’t understand-
Some help with some of this transformation on linear functions would help, you don’t have to necessarily answer all of them, just if you answer two or three i’d be really grateful ;w;
Answer:
1. f(x) - 7
2. The lines do not have same x-intercept
3. a(x) = f(x+7)
4. b(x) = f(x-3)
5. c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)
6. a. g(x) = f(x-8)
b. Slope of g(x) = 1
c. y-intercept = (0, -8)
7. a. p(x)=f(x+6) is vertical transformation of f(x) = x. f(x) is the parent function.
b.(please check explanation section.)
For the second page, here are the answers
5.
a. False
The slope of f(x) will be steeper than m(x)
b. False
The y-intercept doesn't change due to multiplication of 3/5
6. C. h(x) = 3f(x-5)
7. d(x) = 1/4 f(x) + 9
8. Erika: c(x) = 4f(x) + 4 is the first graph
Landry: c(x) = -4f(x) + 3 is the second graph
Step-by-step explanation:
1. f(x) - 7 = x - 7 ( y intercept is translated down when g(x) = x - k )
2. The lines do not have same x-intercept. ( x-intercept of f(x)=x is (0,0) and that of f(x-10) is (0,10)
3. a(x) = f(x) + 7 = x + 7 = f(x+7)
4. b(x) = f(x) - 3 = x - 3 = f(x-3)
5. c(x) = f(x) + 5 = x + 5 = f( x+5)
c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)
6. a. g(x) = f(x) - 8 = x -8 = f(x-8)
b. Slope of g(x) = Slope of f(x)
Slope of f(x) = d(f(x)/dx = dx/dx = 1
Therefore Slope of g(x) = Slope of f(x) = 1
c. y-intercept = (0, -8) (In this case The y-intercept of g (x)=f(x-8) is translated down as -8<0 by 8 units.)
7. b. Look at the graph for part b

Answer:
x = 11/7 y = -1/7
Step-by-step explanation:
2x + y = 3
2x + y - 2y = 3 - 2y
y = 3 - 2x
x - 3(3 - 2x) = 2
x - 9 + 6x = 2
x - 9 + 6x + 9 = 2 + 9
x + 6x = 11
7x = 11
7x / 7 = 11/7
x = 11/7
2(11/7) + y = 3
22/7 + y = 3
22/7 + y - 22/7 = 3 - 22/7
y = -1/7

What is the elimination method?
The elimination method is when you rewrite the two equations so that when added together, one of the two variables (x or y) is eliminated.
Step 1: Multiply the first equation by [tex]3[/tex].
[tex]\implies (3)2x+(3)y=(3)3[/tex]
[tex]\implies 6x+3y=9[/tex]
Step 2: Add the above equation to the second equation to eliminate 3y.
[tex]\begin{array}{r l}6x+3y & = 9\\+\ x-3y&=2\\\cline{1-2}7x&=11 \end{array}[/tex]
Step 3: Solve for x (by dividing both sides by 7).
[tex]\implies \dfrac{7x}{7}=\dfrac{11}{7}[/tex]
[tex]\implies \boxed{x=\dfrac{11}{7}}[/tex]
Step 4: Substitute ¹¹⁄₇ as the value of [tex]x[/tex] in any of the given equations and solve for [tex]y[/tex].
[tex]\implies 2\left(\dfrac{11}{7}\right)+y=3[/tex]
[tex]\implies \dfrac{22}{7}+y=3[/tex]
Step 5: Convert [tex]3[/tex] into a fraction and subtract ²²⁄₇ from both sides of the equation.
[tex]\implies \dfrac{22}{7}-\dfrac{22}{7}+y=\dfrac{21}{7}-\dfrac{22}{7}[/tex]
[tex]\implies \boxed{y=-\dfrac{1}{7}}[/tex]
The solution to the given system of equations is (¹¹⁄₇, -⅐).

4. John, Jim, Jay, and Jack have formed a band consisting of 4 instruments. If each of the boys can play all 4 instruments, how many different arrangements are possible? What if John and Jim can play all 4 instruments, but Jay and Jack can each play only piano and drums?
Answer:
The first part is correct! → There are 4 distinct instruments to distribute to 4 distinct people. And there are 4!=24 distinct ways of doing this.
For the second part. → Jay and Jack can only play 2 instruments, therefore we have 2 instruments for 2 people, and the distribution for these guys can be made in 2!=2 distinct ways.
Then, note that all that is left are 2 distinct instruments for 2 people. So there is an additional 2 distinct ways of doing this distribution for these other guys.
By the product rule, in total, we can do 4 distinct distribution in this condition.
