Help stuck on question number 10
Answer:
y = 2/3x - 5 or in standard form 3y = 2x - 5
Step-by-step explanation:
Remember this fact: Parallel lines have the same slope
Step 1 Solve for y so that the equation is in the slope- intersect form
2x - 3y = 6
-3y = -2x + 6
-3y/-3 = -2x/-3 + 6/-3
y = 2/3 x -2
now we know the slope is 2/3 or
when the equation is in Standard form Ax + By = C you can use this fact: slope = - A/B so the slope = -2/-3 = 2/3
Remember the Parallel lines have the same slope
Find the y-intersect "b" use the slope = 2/3 and point (6, -1)
y = mx + b
-1 = 2/3(6) + b
-1 = 4 + b
-5 = b
Now write the equation of line that is parallel to the given line and passes through point (6, -1)
y = 2/3x - 5 or in standard form 3y = 2x - 5
Zach is trying to decide which of three golf
courses is the best. He randomly surveyed
people at a sports store and recorded the
results in the table. Is the sample method
valid? If so, suppose Zach surveyed 150
more people. How many people would be
expected to vote for Rolling Meadows?
Justify your answer.
Answer:
No, the population of people is poorly represented with this low sample size. 150 would better represent the population as a whole. 42 people would want to play on Rolling Meadows. (according to the previous data)
Step-by-step explanation:
Most likely this small sample size is too small to gain sufficient data from the whole population. If he were to survey a larger sample of people, he would overall better represent the population as a whole. The percentage of people who would prefer Rolling Meadows in the first sample was 28% (7/25). So just multiply 150 times .28 and get 42. 42 people would want to play on Rolling Meadows.
What is the measure of NRS?
Answer:
C. 113°Step-by-step explanation:
(7x - 1) + 79° = 21x + 8
• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.
[tex](7x - 1) +79 = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x + 78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\ \frac{70}{14} = x \\ 5 = x \\[/tex]
NRS = 21x + 8

On a map, 1 inch equals 15 miles. Two cities are 7 inches apart on the map. What is the actual
distance between the cities?
The actual distance between the cities is miles.
Answer:
105 miles
Step-by-step explanation:
The ratio you have is 1:15
So you must multiply 7 by 15 to find the actual distance in miles.
7*15=105
what is one way to find the number of minutes in 7 hours?
Answer:
Seven dived by 60
Step-by-step explanation:
60 minutes makes an hour, so if you divide 7 hours by 60 minutes you could easily get an answer.
Multiplication.
because 1 hour = 60 minutes
and for you, there is 7 hours, you'd just do 7 x 60.
The answer would be the number of minutes (in those seven hours).
7 x 60 is 420 minutes just in case you were wondering.

Step-by-step explanation:
Two sides of a triangle have lengths 6 and 16. Which inequalities represent the possible
lengths for the third side, x?
Answer:
22 > x > 10
Step-by-step explanation:
By the triangle inequality, the length of the 3rd side must be less than the sum of the two other sides and greater than the positive difference of the other two sides. Thus, 6 + 16 > x > 16 - 6
22 > x > 10

Answer:
#13. line QR is 26.
#14. a) x = 2 b) m = 6
Step-by-step explanation:
13. We can use the Pythagorean therom: a^2 + b^2 = c^2
We will substitue PQ for a and PR for b
10^2 + 24^2 = c^2
100 + 576 = c^2
100 + 576 = 676
Then, we find the square root of 676, which is 26.
14. a) 3(2x -1) = 9
we first use distributive property:
6x - 3 = 9
then we add 3 to both sides to counteract the -3:
6x = 12
we divide both sides by 6 to get x alone:
x = 2
b) 3m - 12 = 6
we add 12 to both sides to counteract the -12:
3m = 18
we divide both sides by 3:
m = 6

Mamadou has a points card for a movie theater.

Write and solve an inequality which can be used to determine

v, the number of visits Mamadou can make to earn his first free movie ticket.
Answer:
Inequality: 7.5v+55≥100
Answer: v≥6
Step-by-step explanation:
Have a good day :)
The inequality for the given situation is 7.5v+55≤100.
Given that, Mamadou receives 55 rewards points just for signing up. He earns 7.5 points for each visit to the movie theater. He needs at least 100 points for a free movie ticket.
What is an inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The number of visits Mamadou can make to earn his first free movie ticket is v.
The inequality for the given situation is 7.5v+55≤100
Subtract 55 on both the sides of inequality.
That is, 7.5v+55-55≤100-55
⇒ 7.5v≤45
⇒ v=45/7.5
⇒ v=6
Therefore, the inequality for the given situation is 7.5v+55≤100.

I'm having a bit of trouble finding out how to find the Domain of this function. Help please!
In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?

Omar wants to open an account for his grandchildren that he hopes will have
$80,000 in it after 20 years. How much must he deposit now into an account
that yields 1.75% interest, compounded monthly, so he can be assured of
reaching his goal?
Using compound interest, it is found that he must deposit $56,389.
Compound interest:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.In this problem:
Hopes to have $80,000 in 20 years, thus [tex]t = 20, A(t) = 80000[/tex].Interest rate of 1.75%, thus [tex]r = 0.0175[/tex].Compounding monthly, thus [tex]n = 12[/tex]The investment is of P, for which we have to solve.Then:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]80000 = P(1 + \frac{0.0175}{12})^{12(20)}[/tex]
[tex]P = \frac{80000}{(1 + \frac{0.0175}{12})^{12(20)}}[/tex]
[tex]P = 56389[/tex]
He must deposit $56,389.

17. A salesperson earns a base monthly salary of $2000 plus a 10% commission on sales. The salesperson's
monthly income I (in dollars) is given by the function I(s) = 0.1s + 2000, where s is the sales (in
dollars) that the salesperson makes. Sketch a graph to illustrate each situation using the graph of
I(s) = 0.1s + 2000 as a reference.
A. The salesperson's base salary is increased.
B. The salesperson's commission rate is decreased.
The earning of the salesperson is an illustration of a linear function.
The possible functions in the two scenarios are: [tex]\mathbf{I(s) = 0.1s + 2500}[/tex] and [tex]\mathbf{I(s) = 0.05s + 2000}\\[/tex]
The function is given as:
[tex]\mathbf{I(s) = 0.1s + 2000}[/tex]
When the base salary is increased, a possible function is:
[tex]\mathbf{I(s) = 0.1s + 2500}[/tex]
This is so, because 2500 is greater than 2000
When the commission rate is decreased, a possible function is:
[tex]\mathbf{I(s) = 0.05s + 2000}\\[/tex]
This is so, because 0.05 is less than 0.1
So, the possible functions in the two scenarios are:
[tex]\mathbf{I(s) = 0.1s + 2500}[/tex] and [tex]\mathbf{I(s) = 0.05s + 2000}\\[/tex]
See attachment for the graphs of both functions
