Which statement could be used to explain why f(x)=2x-3 has an inverse relation that is a function
Answers
The function is a one-to-one function.
Explanation:
When an equation is graphed, we use the Vertical Line Test to determine if that equation is a function; if a vertical line hits more than one point anywhere on the graph, the graph is not a function.
This corresponds with the definition of a function: A function is a set of ordered pairs in which each element of the domain (x) is mapped to no more than one element of the range (y). Since every x has no more than one y, there will be no two points hit by the same vertical line.
When we have the graph of a function, to determine if it has an inverse, we use the Horizontal Line Test: if a horizontal line hits more than one point anywhere on the graph, the function does not have an inverse.
This corresponds with the definition of a one-to-one function: A function in which every element of the range (y) is mapped to exactly one element of the domain (x). Since every y has one x, there will be no horizontal line that hits more than one point anywhere on the graph.
I hope it helps, Regards.

What is a linear system of equations?
A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
a) The given system of equations are y=30x+20 -----(i) and y=20x+90 -----(ii)
Fromm equation (i) and (ii), we have
30x+20=20x+90
30x-20x=90-20
10x=70
x=7
b) Substitute x=7 in equation (i), we get
y=30×7+20
y=210+20
y=230
Therefore, the solution of the system of equations is (7, 230).

u/p +u/q = m, if, p is not equal to -q
Answers
Final answer:
To solve the equation u/p + u/q = m, where p is not equal to -q, we can follow these steps: multiply both sides by pq, factor out the common variable u, and then solve for u by dividing both sides by (q + p) and we getu=mpq/(q+p) .
Explanation:
In this equation, u is a variable and p and q are different values. So, the equation can be rewritten as:
u/p + u/q = m
To solve this equation, we need to get rid of the fractions. We can do this by multiplying both sides of the equation by pq:
uq + up = mpq
Now, we can factor out the common variable u:
u(q + p) = mpq
Finally, we can solve for u by dividing both sides of the equation by (q + p):
u = mpq / (q + p)

Answer:
66 + 1 ( not fully shaded ) squares will be shaded.
66.67% region will be shaded
Step-by-step explanation:
It is given that Marks uses a grid to model percent equivalent of .
Let us assume that Mark uses a model containing 100 grids.
Now, as the grids are divided into region equivalent to i.e. it is divided into 3 parts.
Moreover, 2 out of those 3 parts will be shaded.
As,
i.e. =66.67%
So, it gives us that 66 squares in the grid will be fully shaded and one will not be fully shaded.
Hence, 66 + 1 ( not fully shaded ) squares will be shaded and in percent, 66.67% of the region will be shaded.
Final answer:
To represent the fraction 2/3 on a grid, approximately 67% of the squares on the grid should be shaded. This means such a fraction corresponds to 67 out of 100 squares on a 100-square grid or equivalently 67% shaded.
Explanation:
To determine how many grid squares Mark should shade to model the percent equivalent of the fraction 2/3, we need to understand the relationship between fractions, decimals, and percents. When we convert the fraction 2/3 into a decimal, we get approximately 0.67. To represent this as a percent, we multiply by 100, which gives us 67%. So, about 67 out of 100 squares should be shaded.
Let's say Mark's grid has 100 squares (10 rows by 10 columns). In that case, he would shade about 67 squares to represent 2/3 as a percent. If the grid contains fewer than 100 squares, he would need to adjust accordingly.
In summary, the model would show about 67% shaded.
