Devin buys four shirts of equal price for a total of 36$ and teo pairs of shoes for equal price of $25.He has to pay 8% sales tax on his purchases devin decides instead to purchase five shirts and one pair of shoes.If the sales tax is 8% how much will devin pay for his ourchase
Answers
Answer:
$65.88
Step-by-step explanation:
Given data
Sales Tax= 8%
Cost of shirt= $36
Cost of shoe= $25
Total cost= 36+25
Total=$61
Let us find the amount of the Tax
=8/100*61
=0.08*61
=$4.88
Hence the amount paid is
=61+4.88
=$65.88
Which of the statement(s) about the graph shown are true? Select all that apply.
a. An equation for the graph is y=2x^2-9x+7
b. the function has two roots
c. The solutions of the related quadratic equation are -1.5 and -3
d. The related quadratic equation has two solutions
Answers
Step-by-step explanation:
The solutions of the related quadratic equation are -1.5 and -3
To summarize, the true statements are:
(b) The function has two roots.
(d) The related quadratic equation has two solutions.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
To determine which statements about the quadratic function that passes through (1,0) and (3.5,0) are true, we need to use the fact that the roots (or x-intercepts) of a quadratic function can be found by solving the related quadratic equation, which is obtained by setting the function equal to zero.
Let's start with a statement (a). Plugging in the two points given into the equation y = 2x^2 - 9x + 7, we get:
At x = 1, y = 2(1)^2 - 9(1) + 7 = 0
At x = 3.5, y = 2(3.5)^2 - 9(3.5) + 7 = 0
This confirms that points (1,0) and (3.5,0) are indeed on the graph of the function, but it doesn't tell us whether this is the only function that passes through those points. So statement (a) alone is not sufficient to determine the true statements.
Next, let's consider statement (b). Since the graph passes through (1,0) and (3.5,0), we know that it must cross the x-axis at those two points. Therefore, the function has two roots or x-intercepts. Statement (b) is true.
Moving on to statement (c), we need to find the solutions of the related quadratic equation. Setting y = 2x² - 9x + 7 equal to zero, we get:
2x² - 9x + 7 = 0
Using the quadratic formula, we find that the solutions are:
x = (9 ± √(9² - 4(2)(7))) / (2(2)) ≈ 2.5 and ≈ 1.75
Therefore, statement (c) is false.
Finally, statement (d) asks whether the related quadratic equation has two solutions. We just found that it has two solutions, so statements (b) and (d) are true.

The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coordinates. y = f(x) y = g(x) If g(x) = k f(x), what is the value of k? I am not sure how to do this. k = -3
Answers
Answer:
k = -3
Step-by-step explanation:
f(x) = -2x+1
g(x) = 6x - 3
=> g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3
The value of k for the given function will be k = -3.
What is a function?In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be thought of as a machine that takes an input, performs a certain operation on it, and produces an output.
Formally, a function is defined as a set of ordered pairs (x, y) such that each value of x is associated with exactly one value of y. The set of all possible inputs to a function is called its domain, while the set of all possible outputs is called its range.
The given functions are,
f(x) = -2x+1
g(x) = 6x - 3
The value of k will be calculated as,
g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
k= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3
