Determine the equation of the line given by the graph.
A) y = 5/7 x − 2/3
B) y = 5/7 x − 3/2
C) y = 7/5 x − 2/3
D) y = 7/5 x − 3/2
Hello!
I was going to try to use the slope formula, and solve for the y-intercept, but the given graph is hard to distinguish accurate ordered pairs. So, we will find the equation with the graph instead.
Looking at the graph, we can see that the y-intercept is negative. Also, we can also determine that each square represents one unit. So, the y-intercept has to be -3/2 or -1.5. That removes the choices A and C because the y-intercept is in between the values of -1 and -2.
Secondly, the graph has a positive slope. Why? When the x-values increase, the y-values increase. Also, when the x-values decrease, the y-values also decrease. This tells us that the graph has a positive slope (this doesn't remove any choices, but it helps to distinguish which graph has a positive or negative slope).
Finally, we know that if the slope is greater than one, then it is steeper (m > 1). But, if it's less than one, then it becomes less steep (0 < m < 1). Looking at the graph, the graph looks relatively steep (graphing the equations y = 5/7 x - 3/2 and y = 7/5x - 3/2 can help you see the differences between them).
Therefore, the equation of the line given by the graph is choice D, y = 7/5 x − 3/2.
The equation of the line given by the graph is y = 5/7 x - 2/3 (Option A).
Explanation:The equation of the line given by the graph is y = 5/7 x - 2/3 (Option A).
To determine the equation, we look at the slope and y-intercept of the line. The slope of the line can be determined by comparing the change in y-coordinates to the change in x-coordinates between any two points on the line. In this case, the slope is 5/7. The y-intercept is the value of y when x = 0, which is -2/3 in this case.
Therefore, the equation of the line is y = 5/7 x - 2/3.

Dion had 25.00 he purchased the following items for his younger brother using his money. If the tax purchase was 1.85 how much money did dion have left?
he has 77 cents left
1.95*3=5.85
3.60*2=7.20
2.48*3=7.44
1.89+5.85+7.20+7.44+1.85=24.23

Dion has $23.15 left after taking into account all of his purchases as well as the tax.
Explanation:A simple subtraction issue from the subject of mathematics underlies this query. Dion started out with $25.00. We deduct this $1.85 from his initial sum to determine how much money Dion still has if he bought certain products and paid a tax of $1.85 on his purchases. Dion now has $23.15 left after subtracting $1.85 from the $25.00. This is an illustration of how you must deduct purchases and expenses from a total to determine the balance that is left.

Ricardo would swim a farther distance in 1 hour. By taking the number of miles he swam and in the fraction of the hour, you can find the answer.
Divide 5 1/4 by 3 because it took 3/5 of an hour to swim that far. That would lead to 1 3/4 for 1/5 of an hour. Now that we know this, we can multiply 1 3/4 to 5 to get how much he would swim in 1 hour which is 8 3/4
Divide 4 1/2 by 5 because it took 5/9 of an hour to swim that far. That would lead to 9/10 for 1/9 of an hour. Now that we know this, we can multiply 9/10 to 9 to get how much he would swim in 1 hour which is 8 1/10
Since 8 1/10 is less than 8 3/4, Ricardo swam farther

Square roots of given perfect squares are 14, 5, 9. Two of given numbers are not perfect squares (75 and 200) and one number is not defined in this context (2).
Explanation:The square root of a number is a value that when multiplied by itself gives the original number. In other words, √a*b = a if and only if b=a*a. A perfect square is a number that is the square of a whole number. So, the task here is to find the numbers that are perfect squares and then find their square roots.
196 is a perfect square, as 14*14=196, so the square root is 14.
75 is not a perfect square so we do not need to find its square root.
Given '2' is not properly defined in this context, so we can't identify the square root.
25 is a perfect square, as 5*5=25, so the square root is 5.
81 is a perfect square, as 9*9=81, so the square root is 9.
200 is not a perfect square so we do not need to find its square root.

In quadrilateral ABCD, diagonals AC and BD bisect one another:
What statement is used to prove that quadrilateral ABCD is a parallelogram?
(A) Angles BAD and ADC are congruent.
(B) Corresponding angles BCD and CDA are supplementary.
(C) Sides CD and DA are congruent.
(D) Triangles BPA and DPC are congruent.
In order to prove that this quadrilateral is a parallelogram, we need to get the opposite sides to be parallel.
The answer would be D because it shows 2 triangles to be equal. If they are equal then they must have corresponding sides.
The O! Natural Company sells a juice in 1 gallon bottles. The current retail price of the juice is $3.50 for 1 gallon. In order to remain competitive, the company will decrease the price to $3.20. What percent of the original price are consumers going to pay?
Answer:
After the discount, the customer will pay only 91.4% of the initial price.
Step-by-step explanation:
We have that the price of the current retailer, in dollars, is:
3.50
After the discount, the new price, in dollars, is:
3.20
We want to know what percentage of the original price is the final price.
To find out, we must divide the final price between the initial price and then multiply the result by 100%
So:
[tex]\frac{ 3.20}{3.50}[/tex]*100% = 0.914. * 100% = 91.4%
After the discount, the customer will pay only 91.4% of the initial price.
The discount percentage you are going to pay is 100% -91.4% = 8.6% of the initial price

Final answer:
The conjecture that for every integer n, the value of [tex]n^2[/tex] is positive is disproven by the counterexample of squaring zero, as 0 squared equals 0, which is not positive.
Explanation:
The conjecture for consideration is: For every integer n, the value of [tex]n^2[/tex] is positive.
To evaluate this conjecture, we need to look at the definition of integer squares. When we square any positive or negative integer, we multiply the number by itself, resulting in a positive product since a negative times a negative equals a positive. However, the conjecture overlooks the integer zero (0). When we square zero, 02, we get zero, which is neither positive nor negative. Thus, while the conjecture holds for all integers except zero, the case where n is zero provides a counterexample and disproves the original claim
To further illustrate this, let's consider a few examples:
Positive integer: [tex]3^2[/tex] = 9.Negative integer: [tex](-3)^2[/tex] = 9.Zero: 02 = 0 (Counterexample).Given that 0 is not a positive number, we can conclude that the conjecture does not hold true for every integer since it fails for n=0.

The sum of 5 consecutive integers is 110, what is the fourth number in this sequence?
The answer is: " 23 " .
→ The fourth number in the sequence is: " 23 " .
_____________________________________
Explanation:
To solve:
" x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 110 " ;
in which:
"x" = The first number in these sequence;
"(x + 1 )" = the second number in the sequence;
"(x + 2)" = the third number in the sequence;
"(x + 3)" = the fourth number in the sequence;
"(x + 4)" = the fifth number in the sequence;
_____________________________________
Solve for the "fourth number in the sequence" ; or: "(x + 3)" ;
_____________________________________
Given: " x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 110 " ;
↔ " x + x + 1 + x + 2 + x + 3 + x + 4 = 110 " ;
→ Solve for "x" ;
→ then, solve for "(x + 3)" ;
→ which is the fourth number in this sequence;
_____________________________________
→ " x + x + 1 + x + 2 + x + 3 + x + 4= 110 " ;
"5x + 1 + 2 + 3 + 4= 110 " ;
" 5x + 10 = 110 " ;
Solve for "x" :
Subtract "10" from EACH SIDE of the equation; as follows:
" 5x + 10 - 10 = 110 - 10 " ;
to get :
" 5x = 100 " ;
Now, divide EACH SIDE of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" ; as follows:
5x / 5 = 100 / 5 ;
to get:
" x = 20 " .
_____________________________________
Now, to find the fourth number in the sequence:
→ " (x + 3) " ;
→ Substitute "20" for "x" ;
" x + 3 = 20 + 3 = 23" ;
_____________________________________
The answer is: " 23 " .
The fourth number in the sequence is: " 23 " .
_____________________________________
Let us check our work:
If there are five "5" numbers in the sequence, and "23" is the "fourth number" , then: "24" is the "fifth number" .
As such: "22" is the "third number" ; "21" is the "second number" ; and "20" is the "first number" . Is this consistent with: "x = 20" as the "first number" ? Yes!
Thus, "20 + 21 + 22 + 23 + 25 = ? 110 ? ? ;
→ 20 + 21 = 41 ;
→ 41 + 22 = 63 ;
→ 63 + 23 = 86 ;
→ 86 + 24 = 110 . Yes!

Bob spends 4,145 minutes per week taking care of his cows; this includes petting all 53 cows daily, grooming twice a week, and feeding one cow daily.
To calculate the time Bob spends taking care of his cows each week, we need to consider each activity separately and then add the times together:
Petting each cow: 10 minutes per cow per dayAdding these three amounts together gives us a total time spent on care: 3,710 minutes (petting) + 400 minutes (grooming) + 35 minutes (feeding one cow) = 4,145 minutes per week.
