Answer:
Step-by-step explanation:
the first graph has points (-1, -1) and (2, -2)
slope m = (y2-y1) / (x2-x1) = (-1+2)/ (-1-2) = 1/-3 = -1/3
the second graph has points (0, -3) and (2, 0)
slope m = (y2-y1) / (x2-x1) = (-3-0)/ (0-2) = -3/-2 = 3/2
for the table
x. y
-3. 4
0. 1
slope m = dierence in y /diference in x = 4-1 / -3-0 = 3/-3= -1
which number line shows the solution of 5x - 25 greater than -15
Answer:
you need to add number lines, but if you want the equation to be written and solved, then...
Step-by-step explanation:
5x - 25 > -15
+25 +25
5x > 10
divide both sides by 5
x > 2
Hope this helps!!!
A farmer learns of a new type of corn that is supposed to have a higher yield of ears. From previous crops, he knows approximately how many ears of corn 10 plants will produce from the original seeds. The farmer decides to plant the new type of corn to determine if the seeds will produce a higher number of ears of corn. He plants the first 100 seeds of the new type of corn seeds in the field he uses for corn. When it is time to harvest, he randomly selects 10 plants and counts the number of ears. The farmer compares the number of ears with the yield he received the previous year from 10 plants using the original corn seeds. Because the new type of corn produced a higher number of ears, he concludes that the new type of corn does produce more ears of corn. Which of the following statements is not true about this experimental design?
Because the farmer used the seeds from the top of the packet and did not randomly select the seeds, the conclusion is suspect.
Because the farmer used a comparison between the yield of the new type of corn and the yield from the previous corn seeds, the conclusion is valid.
There may be other variables that affected the yield of corn between this year’s crop and last year’s crop; therefore, the conclusion would be suspect.
Because the farmer did not have two groups growing at the same time, one with the new type of corn and one with the original type of corn, the conclusion may be suspect.
Answer:
Because the farmer used a comparison between the yield of the new type of corn and the yield from the previous corn seeds, the conclusion is valid.

Step-by-step explanation:
The mapping diagrams of the given relations are presented using Microsoft Visio as seen in the attached drawings
From the given options, in option A, -5 is paired with both 4 and 3, therefore, giving an input or domain value, -5, that has two outputs in the range which are 4 and 3, therefore, the relationship between the left and right cells in option A is not a function because it is not defined as one input can have several outputs
Hiking The scatter plot shows a hiker's elevation above sea level during a hike
from the base to the top of a mountain. The equation of a trend line for the
hiker's elevation is y = 7.81x + 672, where x represents the number of minutes
and y represents the hiker's elevation in feet. Use the equation of the trend line
to estimate the hiker's elevation after 155 minutes.

Answer:
20 units squared
Step-by-step explanation:
Using pythagorean theorum, we can find the hypotenuse(the long side). [tex]\sqrt{2^2 + 4^2} = \sqrt{20}[/tex]. Since the area of a square is one of the sides multiplied by itself, we get 20 units squared

B
0.3
3.0
D
30.0
Answer:
0.03
Step-by-step explanation:
3% as a fraction is 3/100. as a decimal it is 0.03. notice when you read the decimal aloud, it is three one-hundredths, which is also the same read aloud in a fraction.
Answer:
A

Answer:
2nd option (y = 3/5x-2)
Step-by-step explanation:
First of all, we already know the y intercept is -2, because it shows it on the graph. Also, starting from -2, you can count 5 units on the graph to the right (run), and 3 units above (rise) which will get you 3/5 due to rise over run. This is a positive slope so there is no need to put a negative behind 3/5x.
hope it helped

[tex]\frac{x^2}{3}-\frac{1}{2}=\frac{x}{3}[/tex]
Because there are 3 and 2 as the denominators. Find the lowest number that both 3 and 2 can divide without any quotients, which is 6.
Multiply all whole equation by 6.
[tex]\frac{x^2}{3}(6)-\frac{1}{2}(6)=\frac{x}{3}(6)\\2x^2-3=2x[/tex]
We should get like this. Then move 2x to subtract.
[tex]2x^2-2x-3=0[/tex]
Because the polynomial is a two-degree and a quadratic equation. We solve the value of x by either factoring, using the formula or completing the square.
But I'll use the Quadratic Formula instead as the factoring doesn't seem to work for the Quadratic Equation with square root answers.
[tex]x=\frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]
This is the formula of Quadratic Equation. Ignore the weird letter as it just randomly appears and can't be deleted.
[tex]x=\frac{-(-2)±\sqrt{(-2)^2-4(2)(-3)} }{2(2)} \\x=\frac{2±\sqrt{4+24} }{4} \\x=\frac{2±\sqrt{28} }{4}\\x=\frac{2±2\sqrt{7} }{4} \\x=\frac{1±\sqrt{7} }{2}[/tex]
Therefore, the answer is x = (1±√7)/2
What is f(3) if f(x) = 2x + 1?
Answer:
f(3) = 7
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 2(3) + 1 = 6 + 1 = 7

The coordinates of three of the vertices of a rectangle PQRS are P(-2, 2), Q(4, 2), and R(4, -3). A. Find the coordinates of point S, the fourth vertex of rectangle PQRS. B. What is the perimeter of the rectangle PQRS?
Answer:
The coordinates are (x,y) (-2,-3)
Step-by-step explanation:
We need to take note of the following properties.
1. A rectangle has 4 sides.
2. Two opposite sides of a rectangle are equal.
Coordinates of the triangle on the graph: P(-2, 2), Q(4, 2), R(4, -3) and S(x,y)
The length of the triangle:
We can get this from the x -coordinates of P and Q
Length = |-2 - 4| = 6 (We are only taking positive values for dimensions. You cannot have a negative length)
Recall that the length of the two sides is equal. Therefore, we can relate the length of the second side to its coordinates using the coordinates of R and S
x = 4-6; x = - 2
The breadth of the triangle
We can get this from the y -coordinates of Q and R
Breadth = |-3 -2| = 5 (We are only taking positive values for dimensions. You cannot have a negative breadth)
Recall that the breadth of the two sides is equal. Therefore, we can relate the breadth of the second side to its coordinates using the coordinates of R and S
2 - y = 5; y = -3
Therefore the coordinates are (x,y) (-2,-3)

A shopkeeper buys 10 television sets from a retailer at a rate of Euro 15,000 per set. He sells half of them at a profit of 25 % and rest half at a loss of 20%. Find the overall profit/loss faced by the shopkeeper.
Answer: Profit of $3,750
Step-by-step explanation:
Sold half of the sets at a profit of 25%;
= (15,000 * 5 sets) * 25%
= $18,750
Sold the other half at a loss of 20%;
= (15,000 * 5) * 20%
= $15,000
Profit (loss) = 18,750 - 15,000
= $3,750
