C. 4
D. -4
Answers
slope = 2
Explanation:
The slope of the line can be calculated using the following rule:
slope = [tex] \frac{y2 - y1}{x2 - x1} [/tex]
In the given, we have:
point (-1 , 4) representing (x1 , y1)
point (3 , 12) representing (x2 , y2)
Substitute with the givens in the above formula to get the slope as follows:
slope = [tex] \frac{12 - 4}{3 - -1} = 2[/tex]

It takes a boat going upstream 11 hours and 9 hours downstream. What is the speed of The boat if the current is 2mph
Answers
if it is going down stream it is with the current so there is a 2 mph assistance.
if upstream then 2 mph resistance.
i feel like there should be a given distance
11 hours to get to where, how far?
or simply answer 11-2=9 and 9+2=11. So possibly average it at 10.
You don't need the distance. The only thing that matters is the times (and assuming the same rate is used no matter what the current is doing). The distance coming and going is the same.
d_coming = d_going
t upstream = 11 hours
t downstream = 9 hours
current = 2 mph
rate_up = rate_down = r
General formula
d = r * t
Specific Formula
11(r - 2) = 9(r + 2) Note he seems faster with less time. That olnly means that the current is going in the same direction he is.
Solve
11(r - 2) = 9(r + 2)
11r - 11 =9r + 18 add 11 on both sides.
11r = 9r + 18 + 11
11r = 9r + 29 subtract 9r from both sides.
11r - 9r = 29
2r = 29 divide by 2
r = 29/2
r = 14.5
Answer
The speed of the boat is 14.5 miles per hour.

It takes typically $27 to fill up your tank up with gas. You have allotted no more than $108 on gasoline for your trip. A) Write and B) solve an inequality to find out how many times you will get to fill up your tank up witj gas.
Answers
B) x ≤ 4
Explanation
Let x be the number of times you can fill up. It takes $27 each time, so this gives us 27x. We are budgeting no more than $108 on gas, so this means our inequality will be "less than or equal to":
27x ≤ 108
To solve this, we divide both sides by 27:
27x/27 ≤ 108/27
x ≤ 4
Final answer:
The student can fill up their gas tank up to 4 times within their $108 budget for gasoline. The inequality used to determine this is 27n ≤ 108, solved by dividing both sides by 27.
Explanation:
To solve the student's question regarding how many times they can fill up their gas tank within a $108 budget, we need to set up an inequality and solve it. Let's define the variable n as the number of times they can fill up their tank.
Step A: Write the Inequality
Since it costs $27 to fill up one tank, and the student has budgeted no more than $108 for gas, the inequality will be:
27n ≤ 108
Step B: Solve the Inequality
To find out how many times the student can fill up the tank, we divide both sides of the inequality by 27:
n ≤ [tex]\frac{108}{ 27}[/tex]
n ≤ 4
Therefore, the student can fill up their gas tank up to 4 times within their budget.

Cross multiply.
2y = 7x
Solve for y.
y = 7/2x
C) The slope of the line is 7/2
D) The y-intercept is 0
You know the slope is 7/2 because it is the coefficient of x.
You know the y-intercept is 0 because there is no other number besides 7/2x, which is the slope.
The proportion y/x = 7/2 indicates that the slope of the line is 7/2. Without additional information, we cannot determine the y-intercept from this proportion.
Explanation:Pierce used the proportion y/x = 7/2 when deriving the equation of a line with similar triangles. This proportion suggests that for every 2 units of increase in x, y increases by 7 units. Therefore, the slope of the line, which is the ratio of the change in y (rise) to the change in x (run), would be 7/2. Thus, the correct answer is (c) the slope of the line is 7/2.
Because the question does not provide a specific point on the line, we cannot determine the exact y-intercept from the information given. However, since the proportion does not indicate any specific y-intercept value, we cannot conclude that it is 0, 2/7, or 7/2 without additional information. We only know the relationship between y and x given by the slope.

Anne plans to increase the prices of all the items in her store by 5%. To the nearest cent, how much will the artist save if the artist buys a canvas and a frame that each measure 24 by 36 inches before the price increase goes into effect
Answers
Answer:
Step-by-step explanation:
Let the cost of canvas be $x per sq inches.
Measurement of the canvas bought by the artist is
24 × 36 inches
Area of canvas = 24×36= 864 sq inches
Cost of canvas = 864x
New cost of canvas =x+5% of x
=x+0.05x
=1.05x
New Cost of canvas = 907.20x
Increase in price=907.20x-864x=43.2x
Percentage = [tex]\frac{43.2x}{864x}*100[/tex]
= 5%
Hence artist is going save 5% of cost by buying sheet today.

This equation is of the form y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth expressed as a decimal number, y is the total, and x is the amount of time. For our problem, a is 16; b is 0.35 (35%=35/100=0.35). This gives us the equation above.
find the interquartile range for the data set: 10,3,8,6,9,12,13

Step-by-step explanation:
3, 6, 8, 9, 10, 12, 13,
Median: 9
Lower quartile (Q1): 6
Upper quartile (Q2): 12
(IQR) Interquartile Range: 12 - 6 = 6
The interquartile range for the data set is, 6
We have to given that,
The data set is,
⇒ 10,3,8,6,9,12,13
We can arrange data set in ascending order,
⇒ 3, 6, 8, 9, 10, 12, 13
Hence, First quartile (Q₁) = 6
Second quartile (Q₃) = 12
Hence, The interquartile range for the data set is,
Interquartile range = 12 - 6
Interquartile range = 6

Simplify the expression. (2x^2y)^3
Answers
Answer:
8x6y3 3 and six put at top between y and and threeSure, I'd be happy to show you how to simplify this expression. Here are the steps:
1. In this expression, we have three numbers that are being multiplied together, 2, x^2, and y, and the entire product is raised to the power of 3.
2. Let's take each part of the product individually and raise them to the power of 3.
For the first part, 2 raised to the power of 3: this gives us 8, since 2 * 2 * 2 equals 8.
3. The next part is [tex]x^2[/tex] raised to the power of 3. When raising a power to another power, we multiply the powers together. Therefore, (x^2)^3 becomes x^(2*3), which can be simplified to x^6.
4. Finally, y raised to the power of 3 remains as y^3.
5. So, when we put together all three parts, we obtain the simplified expression, and (2x^2y)^3 simplifies to 8x^6y^3.
So, the simplified expression for (2x^2y) ^3 is 8x^6y^3.
