Answers
Answer:
1. y-intercept = 5
2. x-intercept = -2.5
3. slope = 2
4. y = 2x + 5
Step-by-step explanation:
Part 1
The y-intercept is the point at which the line crosses the y-axis, so when x=0. From inspection of the given graph, the y-intercept is 5.
Part 2
The x-intercept is the point at which the line crosses the x-axis, so when y=0. From inspection of the given graph, the x-intercept is -2.5.
Part 3
The slope of the line is the measure of its steepness. To find the slope of a line, substitute two points on the line into the slope formula.
Two points on the line are the y-intercept and the x-intercept:
(x₁, y₁) = (0, 5)(x₂, y₂) = (-2.5, 0)[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-5}{-2.5-0}=\dfrac{-5}{-2.5}=2[/tex]
Therefore, the slope of the line is 2.
Part 4
Slope-intercept form of a linear equation:

Suppose x and y vary inversely, and x=8 when y=-7 .
c. What is y when x=2 ?
Answers
After the inverse variation y = -28 when x = 2.
What do we mean by inverse variation?A relationship between two variables in which the value of one increases while the value of the other decreases is known as inverse variation.Indirect or inverse variation occurs when two quantities, say X and Y, are related in such a way that increasing X causes a decrease in Y and vice versa.So,
Varies inversely denotes: 1/variableThe initial statement is: y ∝ 1/xTo convert to an equation, multiply by k, the variation constant.
y = k × 1/x = k/xTo find k, apply the given condition.
x = 8 when y = -7:
y = k/x ⇒ k = xy = -7 × 8 = -56So, the equation is: y = -56/x
When x = 2 ⇒ y = -56/2 = -28Therefore, y = -28 when x = 2.

Properties of Functions:
Definition of a Function: A function is a rule or formula that associates each element in the set X (an input) to exactly one and only one element in the set Y (the output). Different elements in X can have the same output, and not every element in Y has to be an output.
Definition of the Domain of a Function: The set of all possible inputs of a function is defined as the domain. The domain of a real-valued function defined by a formula for y in terms of x will be the set of all x input-values that result in a real y output-value unless the domain of the function is further restricted.
Definition of the Range of a Function: The set of all possible outputs of a function is defined as the range. The range of a real-valued function defined by a formula for y in terms of x will be the set of all y output-values that result from the x input-values in the domain.
Function Notation: Given that f(x) is given by some formula containing x, f(B) will be the same formula with each x replaced by B.
Linear Function Definition: If a function may be written in the form f(x) = mx + b where x is the independent variables and m and b are constants, then f(x) represents a linear function. The variable m is defined as the slope and the point (0, b) represents the y-intercept. An equation in this form is known to be in Slope-Intercept Form.
Linear Function Slope Definition: Given that f(x) = mx + b, then m is defined as the slope where:
for any two points (x1, y1) and (x2, y2) on the line. Graphically, the slope represents the change in y with respect to x on the graph of the line.
Linear Functions of Parallel Lines If two linear functions are given by f(x) = m1x + b and g(x) = m2x + b, and m1 = m2, then the graphs of f(x) and g(x) will consist of two lines that are parallel to each other.
Linear Functions of Perpendicular Lines If two linear functions are given by f(x) = m1x + b and g(x) = m2x + b, and m1 = -1/m2, then the graphs of f(x) and g(x) will consist of two lines that are parallel to each other.
Graphs of Even Functions Given a function f(x), if f(c) = f(-c) for all c in the domain, then f(x) is an even function and its graph will have symmetry with respect to the y-axis.
Graphs of Odd Functions Given a function f(x), if f(c) = -f(-c) for all c in the domain, then f(x) is called an odd function and its graph will have symmetry with respect to the origin. Symmetry with respect to the origin implies that a 180-degree rotation of the graph about (0,0) results in an identical graph.

Find the inverse of each function. Is the inverse a function? f(x)=2/3 x-3
Answers
The inverse for the function f (x) = 2 / 3 x - 3 will be f ⁻¹ (x) = 3 / 2 x + 9 / 2.
We are given the function:
f (x) = 2 / 3 x - 3
we need to find the inverse of the function.
First we will write the function in the form of x.
y = 2 / 3 x - 3
y + 3 = 2 / 3 x
2 x = 3 y + 9
x = 3 / 2 y + 9 / 2
So, the inverse function will be:
f ⁻¹ (x) = 3 / 2 x + 9 / 2.
Therefore, the inverse for the function f (x) = 2 / 3 x - 3 will be f ⁻¹ (x) = 3 / 2 x + 9 / 2.

What is the solution of √5 x+4 - √x=4 ?
Answers
The solution is 9.
To find the solution, firstly rewriting the given equation -
√(5x+4) - √x = 4
Now, shifting √x from Left Hand Side to Right Hand side of the equation. Rewriting the equation -
√(5x+4) = √(x) + 4
Taking square of complete equation
(√(5x+4))² = (√(x) + 4)²
Solving the square of equation
5x + 4 = x + 16 + 8√x
Simplifying the equation
5x - x - 8√x = 16 - 4
4x - 8√x = 12
Rewriting the equation
4x - 12 = 8√x
Again taking square on both sides
(4x - 12)² = (8√x)²
16x² + 144 - 2×4x×12 = 64x
16x² + 144 - 96x = 64x
16x² + 144 - 96x - 64x = 0
16x² + 144 - 160x = 0
Dividing the equation by 16
x² + 9 - 10x = 0
x² - 10x + 9 = 0
x² - 1x -9x + 9 = 0
x(x - 1) -9(x - 1) = 0
(x - 1) (x - 9) = 0
x = 1, 9
Keep the value of x in equation to find the solution
x = 1
√(5×1 + 4) - √1 = 4
√(5 + 4) - 1 = 4
√9 - 1 = 4
3 -1 = 4
2 ≠ 4
x = 9
√(5×9 + 4) - √9 = 4
√(45 + 4) - 3 = 4

Answers
The total amount of that Harry will need for the project is nineteen and one third feet and Hence the option B is correct.
Addition of Fraction
Wood 1:
Length of each = 2 3/4 feet
Number of pieces = 4
Total = Length of each × Number of pieces
= 2 3/4 × 4
= 11/4 × 4
= 11 meters
Wood 2:
Length of each = 1 2/3 feet
Number of pieces = 5
Total = Length of each × Number of pieces
= 5/3 ×5
= 25/3 meters
Total amount of wood needed for the project = 11meters + 25/3 meters
= 11 +25/3
= (33+25)/3
= 58/3

what is -9/10 x - 2/3
Answers
Answer:
[tex] \frac{3}{5} [/tex]
Step-by-step explanation:
[tex] -\frac{ 9}{10 } \times - \frac{2}{3} [/tex]
you're going to cancel the 9 using the three then, cancel the 10 using the 2 then you'll have
[tex] - \frac{3}{5} \times - \frac{1}{1} [/tex]
then you will get your answer after finding the product and remember a negative multiplied by a negative is a positive , therefore we. have a positive answer
Show that solving the equation 3 ²x=4 by taking the common logarithm of each side is equivalent to solving it by taking the logarithm with base 3 of each side.
Answers
The solving of equation 3²x=4 in both the given cases gives the answer x = 0.631.
What exactly is an equation?A mathematical statement composed of two representations joined by an equal sign is known as an equation.3x - 5 = 16 is an example of an equation.We obtain the value for the variable x as x = 7 after solving this equation.So,
(1) Common logarithm:
2x log 3 = log 4, or 2x(0.47712) = 0.60206When we solve for x, we get 0.95424x = 0.60206, and x = 0.60206/0.95424.x = 0.631(2) Logarithm with base 3:
2x (log to the base 3 of 3) = (log to the base 3 of 4)This can be reduced to 2x(1) = 2x = (log 4)/log 3 = 1.262.Divide the result by 2 to get x = 0.631Therefore, the solving of equation 3²x=4 in both the given cases gives the answer x = 0.631.

Wha percentage of probability I have to take a pencil of a bag if I have 9 pen 7 pencils and 6 crayons?
Answers
The probability of taking out a pencil from the bag having 9 pens, 7 pencils and 6 crayons is 0.32.
We are given that:
We have-
Number of pens = 9
Number of pencils = 7
Number of crayons = 6
Now, the total number of objects in the bag = 9 + 7 + 6
Now, the total number of objects in the bag = 22
We have to find the probability of taking out a pencil from the bag.
P ( taking out a pencil from the bag ) = 7 / 22
P ( taking out a pencil from the bag ) = 0.32
Therefore, we get that, the probability of taking out a pencil from the bag having 9 pens, 7 pencils and 6 crayons is 0.32.
