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.

Write the equations of the lines described.
The line has a slope of 1/5 and y-intercept of (0, -4)
Answer:
y=1/5x-4
Step-by-step explanation:
Hi there!
We want to write the equation of the line, and we're given that the line has a slope of 1/5, and the y intercept of the line is (0, -4)
There are multiple ways to write the equation of the line, the most popular being slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We are already given the slope (1/5), so we can plug it in as m in the equation.
y=1/5x+b
Now for b, we are also given the y intercept; the value of b is the value of y at the point of the y intercept
In this case, b would equal -4
So substitute -4 as b into the equation:
y=1/5x-4
This is the equation of the line.
Hope this helps!

Set up a proportion and solve.
1) On a map, the key indicates that 2.5 centimeters equal 10 miles. A
road on the map runs for 30 centimeters. How long is the road?
Answer:
120 miles
Step-by-step explanation:
A proportion is a ratio that equals a ratio. I'm going to use cm/miles when I setup the proportion.
[tex]\frac{2.5}{10} =\frac{30}{x}[/tex]
Cross multiply
2.5x = 300
divide
2.5x/2.5 = 300/2.5
x = 120 miles

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

Given system of equations:
[tex]\begin{cases}2x+y=3&\\x-3y=2\end{cases}[/tex]
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).

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:

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:
