Given:
A line passes through the origin and the point (-2,1).
To find:
The slope of the line.
Solution:
If a line passes though two point, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that a line passes through the origin, .i.e., (0,0) and the point (-2,1). So, the slope of the line is
[tex]m=\dfrac{1-0}{-2-0}[/tex]
[tex]m=\dfrac{1}{-2}[/tex]
[tex]m=-\dfrac{1}{2}[/tex]
Therefore, the slope of the line is [tex]-\dfrac{1}{2}[/tex].

A fisherman can row upstream at 2mph and downstream at 8mph. He started rowing upstream till he got tired and the rowed downstream to his starting point. How far did the fisherman row if the entire trip took 2 hours
Answer:
The fisherman row 6.4 miles total.
Step-by-step explanation:
Let the distance from his starting point to the point he turn around is "d" miles.
Given upstream speed is 2 mph and downstream speed is 8 mph.
We now that time = distance /speed
So the time required to row "d "miles upstream = d/2 hours
The time required to row "d" miles downstream = d/8 hours.
As the entire trip took 2 hours so the equation will be :
d/2 +d/8 = 2
( 4d + d ) /8 = 2
5d = 16
d = 16/ 5 = 3.2 miles
So the fisherman rowed a total of ( 3.2 x 2 ) miles = 6.4 miles.
Linear Equation, Need Solved Asap <3
Step-by-step explanation:
y = 5x - 4
When x = 0, y = 5(0) - 4 = -4.
When x = 1, y = 5(1) - 4 = 1.
When x = 2, y = 5(2) - 4 = 6.
The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).
We now check the point (-5,-29):
(-29) : 5(-5) - 4
-29 : -25 - 4
-29 : -29 => -29 = -29.
Since Left hand side = Right hand side, the point (-5,-29) is a solution.
Answer:
1. (1,1) (2,6) (3, 11)
2. Yes
Step-by-step explanation:
1. 5(1)-4 = 5-4 = 1
5(2)-4 = 10-4 = 6
5(3)-4 = 15-4 = 11
(I just chose 3 simple x values and plugged them into the equation to get the y values then wrote it as an ordered pair)
2. 5(-5)-4 = -25-4 = -29
-29 = -29
(Same as number 1 but I used the given x value then I checked if the y value I got matched the ordered pair)

Answer:
D) a = b= 2√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length. This means you have ...
a√2 = 4
a = 4/√2 = 4(√2)/2 = 2√2
Of course, the side lengths are the same (as all answer choices show you). The correct choice is ...
a = 2√2, b = 2√2
In order to convert 3.6 meters into yards, Evin used the following product:
Answer:
2
Step-by-step explanation:
Number 2 was written wrong because it should have been 1 inch / 2.54 centimeters, not the other way around.
This is because the units of the number on the top of the previous one (in this case, centimeters) has to be the same as the units on the bottom of the fraction. This means that if you have cm on top of one, the next one has to have cm on the bottom of the fraction.

The work of a student to solve the equation
2(5y − 2) = 12 + 6y is shown below:
Step 1: 2(5y − 2) = 12 + 6y
Step 2: 7y − 4 = 12 + 6y
Step 3: y − 4 = 10
Step 4: y = 14
Step 5: y = 7
In which step did the student first make an error and what is the correct step? Step 2: 7y − 4 = 6 + 3y
Step 2: 10y − 4 = 12 + 6y
Step 3: 5y − 2 = 2(10 + 3y)

Find the product of the monomial and the polynomial: 4x^3y^3*(3x^3-7xy^2+2xy-y)
Answer: 12x^6y^3-28x^4y^5+8x^4y^4-4x^3y^4
Step-by-step explanation:
The requierd product of 4x³y³ and (3x³-7xy²+2xy-y) is:
12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
The monomial and the polynomial are given in the question, as follows:
4x³y³ × (3x³-7xy²+2xy-y)
To find the product of the monomial 4x³y³ and the polynomial (3x³-7xy²+2xy-y), we need to multiply each term in the polynomial by the monomial and then add the results.
(4x³y³) × (3x³) = 12x⁶y³
(4x³y³) × (-7xy²) = -28x⁴y⁵
(4x³y³) × (2xy) = 8x⁴y⁴
(4x³y³) × (-y) = -4x³y⁴
⇒ 12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴
Therefore, the product of 4x³y³ and (3x³-7xy²+2xy-y) is:
12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

h=(500-260)divided by 2
Answer:
h = 120
Step-by-step explanation:
The required, division of h=(500-260)divided by 2 is 120..
The division is a mathematical operation that involves distributing or sharing a quantity into equal parts. It is the inverse operation of multiplication. In division, a dividend is divided by a divisor to obtain a quotient.
h = (500 - 260) divided by 2
To solve this expression, we first perform the subtraction within the parentheses:
h = (240) / 2
Simplifying further:
h = 120
Therefore, the value of h is 120.

Answer:
$7.22/ft² (Verified Answer) ✅Step-by-step explanation:
We need the unit rate here. The best way to do this is to write a proportion.
Let x = the $ for 1 ft.
130/18 = x/1
130 = 18x
Divide by 18
x = $7.22
Now, we check to make sure we are correct.
130/18 = 7.22/1
130 = 130 ✅
