Answer:
yes
Step-by-step explanation:
Substitute x = - 8 and y = - 7 into the equation
If both sides are equal then (- 8, - 7) is a solution
left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14
right side = 2y = 2(- 7) = - 14
Since both sides are equal then (- 8, - 7) is a solution to the equation

Read the conjecture below. Select all of the true statements about this conjecture. If you multiply two numbers, then the product is greater than either number. Select all that apply. a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4. b. This conjecture is false. There is a counterexample that would prove this conjecture false. c. This conjecture is false: . d. There is not enough information.
Answer:
a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4
b. This conjecture is false. There is a counterexample that would prove this conjecture false.
Step-by-step explanation:
The conjecture is true because, if we multiply two numbers, then their product is greater than either number. As given in the example, 7 × 4 = 28. 28 is greater than both 7 and 4.
Also, if we multiplied a fraction by a whole number, the result would be less than one of the numbers. For example 1/2 × 4 = 2. 2 is greater than 1/2 but not 4. So, the conjecture is false.
If we multiply two fractions, the result is less than both fractions. For example 1/2 × 1/4 = 1/8. 1/8 is less than both 1/2 and 1/4. So, the conjecture is false.
The precious two examples show that there are counterexamples which prove that the conjecture is false although it is true sometimes.
whats the distance between (1,2) and (4,-2)
Answer:
5 units
Step-by-step explanation:
Distance formula:
[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]
Square root of those quantities. x2 and x1 mean the x values from one coordinate and the other, and the same goes for the y-coordinates. So y2-y1 represents (-2) - (2) and x2-x1 = (4) - (1). The answers you get (-4 and 3, respectively), now have to be squared, then added together. So (-4)^2 = 16 and (3)^2 = 9. Add 16 and 9 together you get 25. Final answer, you square root 25 and you get 5. Technically the square root of 25 is both positive and negative 5, but you cannot get a negative number for distance in this case (vectors are different).

The amount Ricky charges for his lawn service varies directly with the number of hours it takes to complete the job. If Ricky charges $112.50 for a 3-hour job, how much money would he charge for a 5-hour job?
The charge for a 5-hour job will be $187.5.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Ricky charges $112.50 for a 3-hour job.
Now,
Since, Ricky charges for 3 hour job = $112.50
Hence, The charges for 1 hour job = $112.50 / 3
= $37.5
So, The charges for 5 hour job = 5 x $37.5
= $187.5
Thus, The charge for a 5-hour job will be $187.5.

Step-by-step explanation:
Given,
6/√3
The denominator is √3.
We know that
The rationalising factor of √a is √a. To rationalise the denominator of 6√√3, we multiply this by √3/√3.
⇛(6/√3)×(√3/√3)
⇛(6√3)/(√3)²
⇛(6√3)/(√3*3)
⇛(6√3)/3
⇛2√3
Hence, the denominator is rationalised.

Find the midpoint of AB if A(-3. 8) and B(-7. -6)
The midpoint of AB is (-5, 1).
To find the midpoint of a line segment AB, we average the x-coordinates of the two endpoints and the y-coordinates of the two endpoints.
Given that A has coordinates (-3, 8) and B has coordinates (-7, -6), we calculate the midpoint as follows:
x-coordinate of midpoint = (x-coordinate of A + x-coordinate of B) / 2
= (-3 + -7) / 2
= -10 / 2
= -5
y-coordinate of midpoint = (y-coordinate of A + y-coordinate of B) / 2
= (8 + -6) / 2
= 2 / 2
= 1
Therefore, the midpoint of AB is (-5, 1), where -5 is the x-coordinate and 1 is the y-coordinate. This means that the midpoint is equidistant from points A and B, dividing the line segment AB into two equal parts.

Your sister is selling Girl Scout cookies that cost $3.50 per box. Your family bought 6 boxes. How many more boxes of
cookies does your sister need to sell to raise $196?
Answer:
She needs $175.
Step-by-step explanation:
3.50 X 6= $21. (196-21=175)
So since she needs $196 and per box it would be $3.50 and 6 boxes is $21 total, she would need to sell 56 boxes total to get to her goal, but since her parents bought 6 boxes already she will only need 50 more.

You are about to graph the linear equation y=1/4x+8 but you need to determine the scale of the x and y axes first. Select the best option for a scale for both the x-axis and y-axis (one of each). A) x scale of -5 to 5 B) x scale of -15 to 15 C) y scale of 0 to 15 D) y scale of -30 to 30 (10 POINTS AND BRAINLIST IF RIGHT WILL REPORT WRONG ANSWERS)
Answer:
B) x scale of -15 to 15
C) y scale of 0 to 15
Step-by-step explanation:
The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)
An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...
-15 ≤ x ≤ 15 . . . . choice B
0 ≤ y ≤ 15 . . . . . . choice C

At a certain college, the ratio to men to women is 5 to 4. If there are 2,800 men, how many women are there?
Answer:
2240
Step-by-step explanation:
braniest pls
there are 2,240 women at the college.
To find the number of women at the college, we can use the ratio of men to women given and the known number of men.
The ratio of men to women is 5 to 4, which can be expressed as 5/4.
If we know that there are 2,800 men, we can set up a proportion:
5/4 = 2,800/x
To solve for x, the number of women, we cross-multiply:
5x = 4 * 2,800
5x = 11,200
Dividing both sides by 5:
x = 11,200 / 5
x = 2,240
Therefore, there are 2,240 women at the college.

Step-by-step explanation:
[tex]7(1 - y) = -3(y-2)[/tex]
Expand the terms in the bracket
That's
[tex]7 - 7y = - 3y + 6[/tex]
Add 3y to both sides of the equation
[tex]7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6[/tex]
Subtract 7 from both sides by the equation
[tex]7 - 7 - 4y = 6 - 7 \\ - 4y = - 1[/tex]

What is subtraction?Finding the difference between two numbers is done using the subtraction technique. The size of a group of things decreases if any of the objects are removed.
For instance, at your birthday celebration, you purchased 9 cupcakes, of which your friends consumed 7. There are only 2 cupcakes remaining for you now. Nine minus seven equals two, which may be represented as the subtraction expression 9 - 7 = 2. (9 - 7) = 2 is the result of subtracting 7 from 9.
According to the question, the given values are :
There are 260 people in the graduating class in 2000, then it increased by 60.
5 years later the people class in the class was 320.
Then in the year 2010, it was 400.
So, the difference between 400 and 320 is 80.
Hence, this concludes that the greatest change will occur in 2010.
