Which statement is true about the graphs of the two lines y=-x+2 and y=-x- ?
O The lines are perpendicular to each other because - and - are opposite reciprocals of each other.
The lines are perpendicular to each other because 2 and - 1 are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 3 are not opposite reciprocals of
each other.
Answer:
The correct option is Option C
Step-by-step explanation:
We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]
The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]
In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)
In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)
The opposite reciprocal of -4/5 is 5/4
So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.
If the lines are parallel there slope must be same. Hence lines are not parallel as well.
So, The correct option is Option C

c

Solve 10=5m/4
Im Confused, Please Help
Answer:
m = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
10 = 5m/4
Step 2: Solve for m
Multiply 4 on both sides: 40 = 5mDivide 5 on both sides: 8 = mRewrite: m = 8Step 3: Check
Plug in m into the original equation to verify it's a solution.
Substitute in m: 10 = 5(8)/4Multiply: 10 = 40/4Divide: 10 = 10Here we see that 10 does indeed equal 10.
∴ m = 8 is the solution to the equation.
A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 95,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 4% each year. How many total fish did the company catch over the first 14 years, to the nearest whole number?
Answer:
54,265 fishes
Step-by-step explanation:
The formula for Population decrease =
P(t) = Po × e^-rt
Where
P(t) = Population after time t
Po = Initial population = 95000
r = decrease rate = 4% = 0.04
t = time in years = 14
Hence
P(t) = 95,000 × e ^- 0.04 × 14
P(t) = 95,000 × e^-0.56
P(t) = 54264.861066 fishes
Approximately = 54,265 fishes
The total fish the company caught over the first 14 years, to the nearest whole number is 54,265 fishes
Which of the following is not an ordered pair from the function f(x) = -3x + 4?
A. (2,-2)
B. (5, -11)
C. (-3, 13)
D. (-6, 21)
The correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.
To determine which of the ordered pairs is not from the function f(x) = -3x + 4, we need to substitute the x-value of each ordered pair into the function and check if it matches the corresponding y-value.
A. (2, -2)
Substituting x = 2 into the function: f(2) = -3(2) + 4 = -6 + 4 = -2
The y-value (-2) matches the given ordered pair. This is a valid solution.
B. (5, -11)
Substituting x = 5 into the function: f(5) = -3(5) + 4 = -15 + 4 = -11
The y-value (-11) matches the given ordered pair. This is a valid solution.
C. (-3, 13)
Substituting x = -3 into the function: f(-3) = -3(-3) + 4 = 9 + 4 = 13
The y-value (13) matches the given ordered pair. This is a valid solution.
D. (-6, 21)
Substituting x = -6 into the function: f(-6) = -3(-6) + 4 = 18 + 4 = 22
The y-value (21) does not match the given ordered pair (-6, 21). This is not a valid solution.
Therefore, the correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.

Kevin graphed the inequality x > 1.
A number line going from negative 3 to positive 5. A closed circle is at 1. Everything to the right of the circle is shaded.
What mistake did Kevin make? Explain.
.
Answer:
Sample: Kevin should have used an open circle on 1, not a closed circle. The closed circle means that 1 is included in the solution set, but the inequality is x > 1, so 1 is not part of the solution.
Mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.
What is open and closed circles?
" Closed circle represents that the value is included in the given range while that of open circle represents given number is not included."
According to the question,
Graph of inequality x > 1 represents all values greater 1 excluding 1.
Number line represents -3 to 5.
A closed circle at 1 means 1 is included.
As per the condition of inequality x > 1 , 1 is excluded while in closed circle 1 is included both are contradictory conditions.
Hence, mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.

In rectangle PLAN, PT = x + 3 and TL = 3x - 11. What are the lengths of PA and NL?
Answer:
PA = 20 units
NL = 20 units
Step-by-step explanation:
Property of a rectangle,
"Diagonals of a rectangle are equal in measure and divide each other in two equal parts"
By using this property,
PT = TL
(x + 3) = (3x - 11)
3x - x = 11 + 3
2x = 14
x = 7
Length of PT = (x + 3) = 10
Length pf PA = 2(PT) = 20 units
Length of NL = PA = 20 units
0.25(x + 4) – 3 = 28
Answer:
x = 120
Step-by-step explanation:
Given
0.25(x + 4) - 3 = 28 ( add 3 to both sides )
0.25(x + 4) = 31 ( divide both sides by 0.25 )
x + 4 = 124 ( subtract 4 from both sides )
x = 120
The value of x that satisfies the equation 0.25(x + 4) - 3 = 28 is x = 120.
Here, we have,
To solve the equation 0.25(x + 4) - 3 = 28, we will follow these steps:
Let's go through each step in detail:
Step 1: Distribute the 0.25 to the terms inside the parentheses.
0.25(x + 4) - 3 = 28
Distribute 0.25 to (x + 4):
0.25x + 0.25 * 4 - 3 = 28
Step 2: Simplify the equation by combining like terms.
0.25x + 1 - 3 = 28
Simplify 0.25 * 4:
0.25x + 1 - 3 = 28
0.25x - 2 = 28
Step 3: Isolate the variable x on one side of the equation.
To isolate the variable x, we want to get rid of the constant term -2 on the left side.
We can do this by adding 2 to both sides:
0.25x - 2 + 2 = 28 + 2
Simplifying:
0.25x = 30
Step 4: Solve for x.
To find the value of x, divide both sides by 0.25:
0.25x / 0.25 = 30 / 0.25
Simplifying:
x = 120
So, the value of x that satisfies the equation 0.25(x + 4) - 3 = 28 is x = 120.
