A ticket to a baseball game costs $32. Each soda at the game costs $4. Shawn may spend no more than $50. He buys 1 ticket and x sodas. (ignore what I wrote already i think it’s wrong)
Answer:
32 + 4x ≤ 50
Step-by-step explanation:
Cost of tickets = $32
Cost of soda = $4
Total spent = $50
When we say "no more than", we mean less than or equal to (≤)
He buys 1 tickets and x sodas
32 + 4x ≤ 50
4x ≤ 50 - 32
4x ≤ 18
Divide both sides by 4
x ≤ 18 / 4
x ≤ 4.5
Shawn can buy more than 4 sodas
Write the equation of the line that passes through the points (4,9) and (9,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y=-8/5x+77/5
Step-by-step explanation:
The equation of line that passes through the points (4, 9) and (9, 1) is y=-8/5x+77/5. Hope it helps!
The equation of line passes through the points (4, 9) and (9, 1) will be;
⇒ y = - 8/5x + 77/5
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 9) and (9, 1)
Now,
Since, The equation of line passes through the points (4, 9) and (9, 1)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 9) / (9 - 4)
m = - 8 / 5
Thus, The equation of line with slope - 8/5 is,
⇒ y - 9 = - 8/5 (x - 4)
⇒ y - 9 = - 8/5x + 32/5
⇒ y = - 8/5x + 32/5 + 9
⇒ y = - 8/5x + 77/5
Therefore, The equation of line passes through the points (4, 9) and (9, 1) will be;
⇒ y = - 8/5x + 77/5

how do I find the value of x so f(x)=7
Answer:
x=5
Step-by-step explanation:
Here we are given with a graph.
we have been asked to find the value of x for which
As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.
Hence we get x=5, then f(x)=7.

A relation is (1 point)
the output (y) values of the relation
the input (x) values of the relation
a set of points that pair input values with output values
x and y values written in the form (x, y)
Answer:
a set of points that pair input values with output values
Step-by-step explanation:
The set of points that relate, input values with output values.
A relation is a set of points that pair input values with output values.
Therefore the correct option is C.
In mathematics, a relation is a set of ordered pairs, where each pair consists of an input value (x) and an output value (y) that are related to each other in some way.
These ordered pairs represent the relationship between the input and output values of the relation.
So, a relation can be represented as a set of points in the coordinate plane, where each point represents an ordered pair (x, y). The relation itself is not specifically the input (x) values or the output (y) values, but rather the collection of all the paired values.
Therefore the correct option is C.

To determine whether they used the same number of tiles, set the two expressions equal to each other and solve for x. Is there a solution for x? Why or why not? If there is a solution, what is it?
Here is the equation stuff to solve:
Expression for the number of tiles Bruce used : 5x+2
Expression for the number of tiles Felicia used : 5x + 5
How could you change the equation so it has infinitely many solutions? What would infinitely many solutions mean in terms of the situation?
T-T
Answer:
Change the +2 from Bruce number of tiles to +5. Infinitely many solutions would mean that they have a equal amount of tiles I think.
