What is the slope of a line through (1, 3) and (-2, 2)?
Answer:
The slope of the line is [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
It's given the points (1,3) and (-2,2). Let's calculate the slope:
[tex]\displaystyle m=\frac{2-3}{-2-1}[/tex]
Calculating:
[tex]\displaystyle m=\frac{-1}{-3}[/tex]
[tex]\displaystyle m=\frac{1}{3}[/tex]
The slope of the line is [tex]\frac{1}{3}[/tex]

The Population of a town was
12000 in 1980 and 16000 in 1990.
What was the percent increase in
the population of the town during
this period?
[2011]
Answer:
33.3%
Step-by-step explanation:
Step one:
given data
Initial population (1980)= 12000
Final population(1990)= 16000
change in population= 16000-12000= 4000
Step two:
% increase= change in population/initail population *100
%increase= 4000/12000*100
%increase= 0.333*100
% increase= 33.3%
A game of football with 11 players lasts for exactly 90 minutes. There are four substitutes that alternate equally. If each player plays for the same length of time, what is the duration? (A) 22.5 mins (B) 18 mins (C) 66 mins (D) none of these
Answer: (A) 22.5 mins
Step-by-step explanation:
Given data:
Duration of the match = 90mins.
Number of substitutes = 4.
Solution:
Since Each of the four (4) substitute players alternated equally, simply means each of the 4 players spent an equal amount of time on the football pitch.
= 90mins/4
= 22.5mins.
Each player spent 22.5minutes on the football pitch.
The division of total time distribute the same time for each substitutes player.
The duration for which each substitute player plays the game of football is 22.5 minutes.
What is division of time?Division of total time by the units of division provides the equal time for each unit.
Given information-
A game of football with 11 players lasts for exactly 90 minutes.
Total number of substitutes is 4.
All the players plays for the same length of time.
As there is total number of substitute players are 4 and the total time duration is 4.
Thus for each player to play same length of time, the time should be divided by the number of players. Therefore,
[tex]t=\dfrac{90}{4} \\t=22.5[/tex]
Hence the duration for which each substitute player plays the game of football is 22.5 minutes.

By claiming 1 more withholding allowance, Mario would have $13 more in his take home pay. How many withholding allowances does Mario currently claim? a. 3 b. 4 c. 5 d. 6 Please select the best answer from the choices provided A B C D
Answer:
The answer would be B.
Step-by-step explanation:
Write an equation of the line with the given slope and y-intercept:
M = 2, B = - 3/4
a. y = 2x + 3/4
b. y = 2x + 3/4
C. y = 2x - 3/4
d. y = 2x + 3/4
Please select the best answer from the choices provided
Answer: C
Step-by-step explanation: Since we know both the slope and the y-intercept we can plug them into Slope-Intercept form. Slope-Intercept form is y=mx+b
Since m = 2 and b = -3/4 all we have to do is replace both m and b in the form and that would be the answer. y = 2x-3/4

The marked price of an electric heater is Rs 1,500. If the shopkeeper allows 15 %
discount and makes a profit of Rs 175, at what price did he purchase the heater?
TL med price of a calculator is Rs 1 800. The shopkeeper allows 10 %
Answer:
1100
Step-by-step explanation:
price = 1500
discount= 15%
15% of 1500 = (15/100)*1500= 15*15= 225
so selling price = 1275
profit is selling price - cost price
1275 - CP = 175
CP = 1275-175= 1100

Slope of perpendicular line is [tex]\frac{1}{4}[/tex]
y - 1 = - 4(x - 2) ⇔ y = - 4x + 9
Equation of the perpendicular to KL from point M(4, - 3) is

y - 1 = - 2(x - 2) ⇔ y = - 2x + 5
Equation of the perpendicular to LM from point K(3, - 3) is

Step-by-step explanation:
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

A. It is shifted right.
B. It is shifted down.
C. It is flipped over the x-axis.
D. It is vertically compressed.
E. It is vertically stretched.
Answer:
Shifting down.
Vertically compressed
Step-by-step explanation:
Given
[tex]f(x) = 2^x[/tex]
[tex]g(x) = \frac{1}{3}(2^x - 7)[/tex]
Required
Determine the translation from f(x) to g(x)
The first translation from f(x) towards g(x) is:
[tex]f(x) = 2^x[/tex]
[tex]f'(x) = 2^x - 7[/tex]
This is derived by:
[tex]f'(x) = f(x) - b[/tex]
Where
[tex]b = 7[/tex]
Notice that, in the above, b (i.e. 7) was subtracted from f(x), this implies that the function shifted down
The next translation that resulted in g(x) is:
[tex]g(x) = \frac{1}{3}(2^x - 7)[/tex]
This is derived by:
[tex]g(x) = a.f'(x)[/tex]
By comparison:
[tex]a = \frac{1}{3}[/tex]
Since the value of a is less than 1, then f'(x) is vertically compressed to give g(x).
Hence, the transformations that apply from f(x) to g(x) are:
Shifting down. Vertically compressedAnswer:

A. the equation has two true solutions
B. the equation had one true solution
C. the equation has one extraneous solution
D. the equation has one true solution and one extraneous solution
Answer:
C. the equation has one extraneous solutionStep-by-step explanation:
Given equation:
x/(x - 1) + 2/(x + 2) = -6/(x² + x - 2)Common denominator is x² + x - 2, consider x ≠ 1 and x≠ -2
Multiply both sides by x² + x - 2:
x(x + 2) + 2(x - 1) = -6x² + 2x + 2x - 2 + 6 = 0x² + 4x + 4 = 0(x + 2)² = 0x + 2 = 0x = -2There is one solution but it is not true one.
Option C is correct
Answer:
[tex] \frac{x}{x - 1} + \frac{2}{x + 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ \frac{x(x + 2) + 2(x - 1)}{(x - 1)(x + 2)} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 2x + 2x - 2 }{ {x}^{2} + 2x - x - 2} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 4x - 2 }{ {x}^{2} + x - 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ {x}^{2} + 4x - 2 = - 6 \\ {x}^{2} + 4x + 4 = 0 \\ {x}^{2} + 2 \times 2 \times x + {2}^{2} = 0 \\ {(x + 2)}^{2} = 0 \\ x + 2 = 0 \\ \boxed{x = - 2 }[/tex]
x =-2 is the right answer.C. the equation has one extraneous solution.

When expressing the reciprocal of $1.67$ as a simplified fraction, what number do you get if you subtract the numerator from the denominator?
Answer:
67
Step-by-step explanation:
Aops Question
The value if you subtract the numerator from the denominator will be -67.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that expressing the reciprocal of $1.67$ as a simplified fraction. The number when you subtract the numerator from the denominator will be calculated as below:-
Fraction form of the number 1.67 = 167 / 100.
The subtraction of numerator from denominator = 10 - 167 = -67
Therefore, the value of subtraction of the numerator from the denominator will be -67.

I need help finding the value
Answer:
17
Step-by-step explanation:
First, we notice that the triangle is isosceles . (In case you didn't know, the two tick marks on the sides of the triangle signify that they are congruent and have the same length.) Since the triangle is isosceles, we can apply the Base Angles Theorem.
The Base Angle Theorem states that the two angles opposite of the two congruent sides are also congruent. In this case, we can say that, because the angle measuring 29° and the third(top) angle are opposite to the two congruent sides, those two angles are congruent. Therefore, the third angle measures 29° as well.
Now that we know this, we can write the following equation:
29°+29°+(11x-65)° = 180.
Solving this equation, we have x = 17.

What is an
equation of the line that passes through the points (-1,-4) and
(-2,-8)?
Answer:
y = 4x
Step-by-step explanation:
To start, we need to find the slope:
m = y₁ - y₂ / x₁ - x₂
Substitute the numbers and solve for the slope:
m = -4 - (-8) / -1 - (-2)
m = -4 + 8 / -1 + 2
m = 4 / 1
m = 4
Now we know that the slope is 4.
Next, we need to use point-slope form:
y - y₁ = m(x - x₁)
Once more, substitute the numbers:
y - (-4) = 4(x - (-1))
y + 4 = 4(x + 1)
y + 4 = 4x + 4
y = 4x
Therefore, the equation of the line is y = 4x.
