The statement that best describes the solutions to the given system of equations - There are two possible solutions, but only one of the solutions is viable.

"It is a point or set of points (x, y) that satisfies all the constraints of the given problem."

"It is a solution that makes sense in context as well as mathematically. "

"It is a set of equations for which we find a common solution."

For given question,

Three classmates want to know when a tennis ball and a balloon will reach the same vertical height above the ground.

Given that, x represents the time, in seconds, since the timer starts.

The graph shows the vertical height of the tennis ball and balloon, in feet.

The solution to the system of equations are the points at which the graphs to the system of equations intersect each other.

From the given graph we can observe that,

the graphs intersect at points having the x values near x = 1.2 and x = -3.2 This means, there are two possible solutions.

But we know that the negative value of x (time) is not viable.

Therefore, the statement that best describes the solutions to the given system of equations - There are two possible solutions, but only one of the solutions is viable.

Answer: 1.5x

Step-by-step explanation:

If the figure dilates by 1.5 times it will increasingly do the same with the perimeter. It keeps the same ratio of 1.5x.

Ex: If a side of the figure was originally 10 and the dilation factor is 1.5 the side now with be 15. This goes for all sides.

Step-by-step explanation:

The given inequality is :

x – 2y > 16

We need to draw the graph of this inequality.

If x = 0,

-2y>16

y>-8

If y = 0,

x>16

So, we can draw the graph as follows :

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]

[tex]m = \frac{ - 5 - ( - 7.5)}{2 - ( - 3)} = \frac{2.5}{5} = \frac{1}{2} \: or \: 0.5[/tex]

Standard form of slope-intercept:

y = mx + b

wherein m is the slope and b is the y-intercept.

Let's substitute all values into the equation

[tex]y = 0.5x - 6[/tex]

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.

Step-by-step explanation:

Answer:

Ricky had 1205 hits. Pedro had 1481 hits.

Step-by-step explanation:

Set variables.

Set up an equation.

Pedro and Ricky got 2686 base hits total.

Pedro had 276 more hits than Ricky.

Plug p into your first equation.

Combine like terms.

Divide both sides by 2 to isolate r.

You now know that Ricky had 1205 hits. Pedro had 276 more hits than Ricky. Therefore,

Pedro 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.

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]

The function that has an inverse that is also a function is [tex]x = 3\cdot y + \frac{9}{4 }[/tex].

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'.

Step-by-step explanation:

All the angles that have a cosine of 9/15 are,

⇒ ∠P and ∠X

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Triangle PQR is similar to triangle XYZ.

Hence, We get;

In triangle PQR,

cos P = 9/15

And, In triangle XYZ,

cos X = XZ / ZY

cos X = 9 / 15

Thus, All the angles that have a cosine of 9/15 are,
