Answer:
0. See explanation below.
Step-by-step explanation:
Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.
For rounds 1 to 4,
4 + 7 + 1 + -12 = 12 - 12 = 0
The summation of points in the first four rounds already results to a zero.
Let us see if the addition of any of the three options for round 5 will still result in a zero!
0 + -24 = -24
0 + -11 = -11
0 + 12 = 12
So all the options here are wrong. The only option that would have been correct is 0.
Since 4 + 7 + 1 + -12 + 0 = 0
Maybe the complete question has 0 as the fourth option. Use that.

how to graph f(x)=7|x -4|-1
Answer:
here I drew it digitally Hope it helps
Step-by-step explanation:
The graph of the function is a V-shaped curve.
Given that we need to determine the graph of the function f(x) = 7|x - 4| - 1.
To graph the function f(x) = 7|x - 4| - 1, you can follow these steps:
Start by identifying the key points of the function. In this case, the function involves an absolute value, which means it may change direction at the point inside the absolute value.
Set the expression inside the absolute value equal to zero and solve for x to find this critical point:
|x - 4| = 0
x - 4 = 0
x = 4
So, the critical point is x = 4.
Next, consider the behavior of the function on each side of the critical point.
Choose some values of x less than and greater than 4 and substitute them into the function to determine the corresponding y-values.
Let's choose x = 2:
f(2) = 7|2 - 4| - 1
f(2) = 7|-2| - 1
f(2) = 7(2) - 1
f(2) = 14 - 1
f(2) = 13
Let's choose x = 6:
f(6) = 7|6 - 4| - 1
f(6) = 7|2| - 1
f(6) = 7(2) - 1
f(6) = 14 - 1
f(6) = 13
Therefore, we have the points (2, 13) and (6, 13) on the graph.
Plot the critical point and the points you found on the coordinate plane. Mark them on the x-axis and y-axis.
To graph the absolute value part of the function, draw a V-shaped curve with the vertex at the critical point (4, 0).
The arms of the V-shaped curve will pass through the plotted points (2, 13) and (6, 13).
Extend the arms of the V-shaped curve indefinitely in both directions.
Finally, add the constant term (-1) by shifting the entire graph down by 1 unit. This means that every y-value on the graph should be reduced by 1 unit.
Your completed graph of the function f(x) = 7|x - 4| - 1 should resemble a V-shaped curve with its vertex at (4, -1), passing through the points (2, 12) and (6, 12), and extending infinitely in both directions.
The graph of the function is attached.

Together, teammates Pedro and Ricky got 2686 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each player have?
Answer:
Ricky had 1205 hits. Pedro had 1481 hits.
Step-by-step explanation:
Set variables.
Pedro = pRicky = rSet up an equation.
Pedro and Ricky got 2686 base hits total.
p + r = 2686Pedro had 276 more hits than Ricky.
p = r + 276Plug p into your first equation.
(r + 276) + r = 2686Combine like terms.
2r + 276 = 26862r = 2410Divide both sides by 2 to isolate r.
r = 1205You now know that Ricky had 1205 hits. Pedro had 276 more hits than Ricky. Therefore,
p = r + 276p = 1205 + 276p = 1481Pedro had 1481 hits.
Check your work.
total hits = Pedro's + Ricky's
2686 = 1481 + 1205
2686 = 2686
Pedro's hits = Ricky's hits + 276
1481 = 1205 + 276
1481 = 1481
Your answers are correct.
Calculate a rough estimate of the total lineal footage of lumber needed for a rectangular house 35’ x 40’?
A. 375’
B. 1,500’
C. 3,000’
D. 750’
Answer:
B. 1,500’
Step-by-step explanation:
Given;
dimension of the rectangular house, = 35’ x 40’
The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'
The rough estimate should be greater than the actual estimate in 100s;
rough estimate = 1,400' + 100' = 1,500'
Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.

Which function has an inverse that is also a function?
Can someone please help me with this problem?
Answer:
The function that has an inverse that is also a function is [tex]x = 3\cdot y + \frac{9}{4 }[/tex].
Step-by-step explanation:
The only function whose inverse is also a function is the linear function, also named first-order polynomial. The inverse of a linear function is also a linear function. That is:
[tex]y = \frac{1}{3}\cdot x -\frac{3}{4}[/tex]
[tex]\frac{1}{3}\cdot x = y + \frac{3}{4}[/tex]
[tex]x = 3\cdot y + \frac{9}{4 }[/tex]

Answer: y=0.5x-6. She forgot the y-intercept
Step-by-step explanation: use the slope formula to get the slope of 0.5 and just add in the y-intercept of -6 since:
y=mx+b
m=slope
b=y-intercept
Answer:
y = 0.5x - 6
Step-by-step explanation:
[tex]since \: there \: are \: two \: points \: \\ m = \frac{y2 - y1}{x2 - x1} [/tex]
