Answer: The answer is y=-3x
Step-by-step explanation: You can see in the picture that the line is going down which represents a negative slope so you can eliminate C and D. Now you are left with A and B. 1 unit up is equal to 3 so the rise over run is -3/1 and that translates to Y=-3x answer B

Frank wants to go bowling. The bowling alley charges $4 per game and a one-time charge of $3 for bowling shoes. Consider the following information. y = 4x + 3y is the total cost of bowling x is the number of games bowled Based on the information, which statement is TRUE?
A. The total cost will increase by $4 for every game bowled.
B. The total cost will increase by $3 for every game bowled.
C. The total cost will increase by $4 for every 3 games bowled.
D. The total cost will increase by $3 for every 4 games bowled.
Answers
Answer:
A:The total cost will increase by $4 for every game bowled
Step-by-step explanation:
$4 per game not 3 games or 4 game is per game
The correct statement is:
The total cost will increase by $4 for every game bowled.
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
Given:
Total cost of bowling = 4x + 3y
where x is the number of games.
Now, every time the game played they charged it for $4 per game.
So, when there 2 games then the charges will be $8 for two games.
Hence, the correct statement is The total cost will increase by $4 for every game bowled.

The height y (in feet) of a baseball t seconds after it is hit can be modeled by the function y = −16t2 + 96t + 3. About how long does it take to hit the ground?
Answers
Answer:
6.03 seconds
Step-by-step explanation:
Given
[tex]y = -16t\² + 96t + 3[/tex]
To solve this, we simply set the height to 0.
i.e. [tex]y = 0[/tex]
So, we have:
[tex]-16t\² + 96t + 3 = 0[/tex]
Solve using quadratic formula.
[tex]t = \frac{-b+-\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = -16[/tex]
[tex]b = 96[/tex]
[tex]c = 3[/tex]
[tex]t = \frac{-96+-\sqrt{96^2 - 4 * -16 * 3}}{2 * -16}[/tex]
[tex]t = \frac{-96+-\sqrt{9216 +192}}{-32}[/tex]
[tex]t = \frac{-96+-\sqrt{9408}}{-32}[/tex]
[tex]t = \frac{-96+-96.9948452239}{-32}[/tex]
[tex]t = \frac{-96+96.9948452239}{-32}[/tex] or [tex]t = \frac{-96-96.9948452239}{-32}[/tex]
[tex]t = \frac{0.9948452239}{-32}[/tex] or [tex]t = \frac{-192.994845224}{-32}[/tex]
[tex]t = -0.031088913245535[/tex] or [tex]t = 6.0310889132455[/tex]
Since time can't be negative, we have:
[tex]t = 6.0310889132455[/tex]
[tex]t = 6.03\ seconds[/tex] (approximated)

If the function f(x)= 2x – 3 and g(x) = 3/2x + 1 then which of the following is a true statement?
f(0) > g(0)
f(8) = g(8)
f(2) = g(2)
g(4) < f(4)
Answers
Answer:
f(8) = g(8)Step-by-step explanation:
Given
f(x)= 2x – 3 and g(x) = 3/2x + 1
f(0)= 2(0)-3
f(0) = -3
g(0) = 3/2(0)+1
g(0) = 0+1
g(0) = 1
Hence since -3 < 1, this means that f(0)<g(0)
Also;
f(8)= 2(8)-3
f(8) = 16-3
f(8) = 13
g(8) = 3/2(8)+1
g(8) =12+1
g(8) = 13
This shows that g(8) = g(8)
Hence g(8) = g(8) is a true statement

Write an equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis.
Answers
The equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis is y=0x+7 or y=7.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
As it is needed that the line must be perpendicular to the y-axis, therefore, the slope of the line will be 0 and the value of y will be 0. Also, it is given that the line passes through (4, 7). Therefore, the equation in slope-intercept form for the line is,
y = mx + c
7 = 0(4) + c
c = 7
Hence, the equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis is y=0x+7 or y=7.

A six-sided number cube is rolled twice.
Choose all of the dependent events.
A. The event that the first roll is a 3 or 4, and the event that the sum of the rolls is greater than 7.
B. The event that the first roll is greater than 3, and the event that the second roll is less than 3.
C. The event that the first rollis even, and the event that the second roll is also even.
D. The event that the first rollis odd, and the event that the sum of the rolls is 8.
E. The event that the first rollis odd, and the event that the second roll is a 1.
Answers
Answer: A and D
Step-by-step explanation:
Dependent events mean that one event depends on the outcome of the previous event.
A) If the first roll is a 3, and we want to sum more than 7 with the second roll, then the possible outcomes 5 and 6. Now if the first roll is 4, then the possible outcomes for the second event will be 4, 5 and 6. So you can see how the outcome space of the second event changes depending on the first event, so the events are dependent.
B) Here we do not have dependence, each event only depends on it's own outcome.
C) Again, both events only depend on it's own outcome, so the events are not dependent.
D) This is similar as the case for A, these events are dependent because is not the same if the outcome of the first event is 3, than if the outcome is 5 (the outcome needed for the second roll changes depending on the outcome of the first event)
E) Same as B and C, the events are independent.

Function f is symmetric around point (4, -1). This point is the minimum of the function f
Step-by-step explanation:
The vertex-form of the quadratic function is y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of its vertex pointThe graph of the quadratic function is a parabola symmetric at the vertex point (h, k), which is the lowest or the highest on the graphIf the vertex is the lowest point then, it is minimum, if it is the highest point, then it is maximumLet us solve the question
→ From the given graph
∵ The graph represents a quadratic function f(x)
∵ It has the lowest vertex
∴ The vertex is minimum
∵ The coordinates of the vertex are (4, -1)
∵ The is symmetric around the vertex point
∴ The function is symmetric around point (4, -1)
Function f is symmetric around point (4, -1). This point is the minimum of the function f

4x + 3 < 5x − 6
Answers
Answer:
x > 9
Step-by-step explanation:
Isolate the variable, x. Treat the < as an equal sign, what you do to one side, you do to the other.
First, subtract 5x and 3 from both sides of the inequality:
4x (-5x) + 3 (-3) < 5x (-5x) - 6 (-3)
4x - 5x < -6 - 3
-x < -9
Isolate the variable, x. Divide -1 from both sides. Note that when you divide or multiply by a negative number, you must flip the sign:
(-x)/-1 < (-9)/-1
x < -9/-1
x > 9
x > 9 is your answer.
