Write an equation in slope- intercept form of the line through points S(-7,-6) and T(10,8)

Answers

Final answer:

The slope-intercept form of the line passing through points S(-7,-6) and T(10,8) is calculated by first determining the slope or 'rise over run' which is 14/17. Subsequently, the slope and point T(10,8) are used to find the y-intercept which is -8/17. Hence, the equation of the line is y = 14/17x - 8/17.

Explanation:

To create an equation in the slope-intercept form we first need to find the slope or rise over run given our two points S(-7,-6) and T(10,8). The formula to find the slope (m) = (y2 - y1) / (x2 - x1). By substituting the values into the formula we get (8-(-6)) / (10-(-7)) = 14/17, which is our slope (m).

Next, we use the slope (m) and one point, let's take T(10,8), in the equation y = mx + b to find the y-intercept (b). Substituting the known values into the equation gives us 8 = 14/17*10 + b. Solving for b gives us b = -8/17.

Therefore, the slope-intercept form of the line passing through the given points S(-7,-6) and T(10,8) is y = 14/17x - 8/17.

Final answer:

To write the equation of a line in slope-intercept form, find the slope and y-intercept. For the points S(-7,-6) and T(10,8), the equation is y = (14/17)x + 70/17.

Explanation:

To write the equation of a line in slope-intercept form, we need to find the slope (m) and the y-intercept (b). The slope can be found using the formula:

m = (y2 - y1) / (x2 - x1)

After finding the slope, we can substitute it along with one of the given points into the slope-intercept form equation: y = mx + b, where y and x are the coordinates of any point on the line. Solving the equation will give us the value of the y-intercept.

So, for the given points S(-7,-6) and T(10,8),

Find the slope: m = (8 - (-6)) / (10 - (-7)) = 14/17Substitute the slope and one point into the slope-intercept form equation: Solve for b: -6 = -98/17 + b, b = -6 + 98/17, b = 70/17Therefore, the equation in slope-intercept form is: y = (14/17)x + 70/17

6i(6i) = 36i², or -36 (note, i² = -1)

Three golfers, Vijay, Ernie, and Phil , during five years had a total of 221 top-10 finishes. Ernie had 13 more top-10 finishes than Phil. Vijay had 16 more top-10 finishes than Phil. Determine the number of top-10 finishes for each golfer.

Answers

For this case what you must do first is to define the following variables:
x: number of top-10 finishes for Vijay.
y: number of top-10 finishes for Ernie.
z: number of top-10 finishes for Phil.
We write the following system of equations:
x + y + z = 221
y = 13 + z
x = 16 + z
Solving the system we have:
Step 1:
x + y + z = 221
(13 + z) + (16 + z) + z = 221
3z + 29 = 221
z = (221-29) / (3)
z = 64
Step 2:
y = 13 + z
y = 13 + 64
y = 77
Step 3:
x = 16 + z
x = 16 + 64
x = 80
Answer:
the number of top-10 finishes for each golfer is:
Vijay: 80
Ernie: 77
Phil 64

Correlation most likely implies causation in the following case: As rainfall increases, the number of umbrellas sold increases.

"Correlation doesn't always imply causation" is a common saying in statistics. Sometimes when there's a high correlation coefficient between two variables, that doesn't always mean that one is the cause for the other.

When rainfall increases, people are in need of umbrellas and often buy new ones, so for this pair of variables, the correlation most likely implies causation.

What is the period of y = 3cot(4x - 3pi)

Answers

4x = 2π when x = π/2

The period is π/2.

The period of y = 3cot(4x - 3pi) is π/2 units.

The period of the function y = 3cot(4x - 3π) is calculated as the reciprocal of the absolute value of the parameter in front of x.

To find the period, identify the coefficient of x, which is 4 in this case. The period is then given by 2π/|4| = π/2.

Therefore, the period of the given function y = 3cot(4x - 3π) is π/2 units.

a copper alloy that is 40% copper is to be combined with a copper alloy that is 80% copper to produce 120 kilograms of an alloy that is 70% copper. how many kilograms of each alloy must be used? please work it out

Answers

Try this way:
1. note, that in such tasks mass of pure copper before merging and after merging is the same (this is the base);
2. If the mass of pure copper in alloy with 40% solution is 'x' and the mass of pure copper in alloy with 80% solution is 'y', then It means before merging was x/0.4 and y/0.8, after merging was (x+y)/0.7. It is one equation of the future system.
3. Using 120 kg. of 70% solution, it is possible to define mass of pure copper after merging, 120*0.7(=84 kg.). And before merging it was 'x+y' kg. of pure copper. It is the second equation of the future system.
4. according to the items no.2&3 (to make up the system of two equations and solve it). All the details are in the attached picture.
5. pure copper in 40% solution is 12 kg., pure copper in 80% solution is 72 kg. It means, that the copper alloy with 40% solution is x:0.4=12/0.4=30 kg., and the copper alloy with 80% solution is y:0.8=72/0.8=90 kg.

After setting up and correcting a system of equations, the student needs to use 30 kg of the 40% copper alloy and 90 kg of the 80% copper alloy to create 120 kg of a 70% copper alloy.

To solve this problem, we need to set up a system of equations. Let x be the amount of 40% copper alloy needed, and y be the amount of 80% copper alloy needed.

First, we have the total weight equation:

x + y = 120 kg (the final alloy's total weight)

Next, we have the copper content equation:

0.40x + 0.80y = 0.70 × 120 kg (the final alloy's copper content)

Now, let's solve this system of equations:

Address the second equation: 40x + 80y = 8400

Express x in terms of y: 40x = 8400 - 80y

Divide by 40: x = 210 - 2y

Substitute x in the first equation: (210 - 2y) + y = 120

Solve: 210 - y = 120, y = 90 kg

Finally, substitute the value of y back into x = 210 - 2y: x = 210 - 2 imes 90 = 210 - 180 = 30 kg

So, we need 30 kg of the 40% copper alloy and 90 kg of the 80% copper alloy.

Latifah makes $12 per hour. She works 18 hours per week. She calculates that in 4 weeks, she will earn $864. If her hourly rate and weekly hours are rounded to the nearest ten, which amount represents an estimate of the amount she will make over 4 weeks? Is her original calculation reasonable?

Answers

here is the steps to figure it out with the answer:
she makes $216 per week. If her hourly rate and weekly hours are rounded to the nearest tenth then it would make her weekly pay $200. Her hourly pay is now $10 and her weekly hours are 20. Now multiply the 20 (weekly hours) by 4 (which would be 4 weeks) 20x4= 80. So 80 hours in 4 weeks. Now her hourly pay is $12 rounded to the nearest tenth = $10 per hour. SOOO the $10 multiplied with the 80= $800 in 4 weeks.

Answer and step-by-step explanation:

Rounding her hourly rate to the nearest ten, we get $10.

Rounding her number of hours to the nearest ten, we get 20.

This gives us an estimate of 10(20)(4) = $800

Her original calculation is reasonable; it is higher because the actual hourly rate is larger than the estimate, so her amount of pay should be higher than the estimate.
