Answer:
y = -3x + 7
Step-by-step explanation:
Using any 2 pairs of values, say (-3, 16) and (-1, 10), therefore, rate of change of the data given = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{10 - 16}{-1 -(-3} = \frac{-6}{2} = -3 [/tex].
We would get the same rate of change if we use any other two pairs of values in the data given.
Therefore, the data can be modeled by a linear equation because the rate of change remains constant all through.
To represent y as a function of x, find b, since we know the rate of change (m).
Substitute x = -3, y = 16 and m = -3 in y = mx + b.
Thus:
16 = (-3)(-3) + b
16 = 9 + b
Subtract 9 from each side
16 - 9 = b
7 = b
b = 7
Substitute m = -3 and b = 7 in y = mx + b
The function would be:
✅ y = -3x + 7

A una obra de teatro acudieron 420 personas y se recaudaron $48,000.00. Si el costo de la entrada de los adultos fue de $200 y el costo de la entrada de niños costaba $80. ¿Cuántos adultos y niños que acudieron?
Answer:
La respuesta es que acudieron 120 adultos y 300 niños.
Step-by-step explanation:
De acuerdo a la información proporcionada, puedes escribir las siguientes ecuaciones:
x+y=420 (1)
200x+80y=48,000 (2), donde:
x es el número de adultos
y es el número de niños
Primero, puedes despejar x en (1):
x=420-y (3)
Ahora, puedes reemplazar (3) en (2):
200(420-y)+80y=48,000
84,000-200y+80y=48,000
84,000-48,000=200y-80y
36,000=120y
y=36,000/120
y=300
Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:
x=420-y
x=420-300
x=120
De acuerdo a esto, la respuesta es que acudieron 120 adultos y 300 niños.

if g(x)=2(x-4), find the value of x if g(x)=20
1) 32
2) 12
3) 14
4) 10
please HELP
Answer:
3) 14
Step-by-step explanation:
in the given equation replace the "g(x)" with the provided "20"
20=2(x-4) solve as usual
divide each side by 2
10=x-4
add 4 to each side
14=x
the value of x is 14
A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y = -4x2 + 141x – 703
Answer:
b
Step-by-step explanation:
The maximum amount of profit the company can make is $543
Let y represent the amount of profit and x represent the selling price.
The relationship between x and y is:
y = -4x² + 141x – 703
The maximum profit is at dy/dx = 0, hence:
dy/dx = -8x + 141
-8x + 141 = 0
8x = 141
x = 17.625
The maximum profit is:
y = -4(17.625)² + 141(17.625) – 703 = 543
The maximum amount of profit the company can make is $543

Kiran and Clare live 24 miles away they start walking at 8 am Clare is walking 3.4 miles per hour and they get there at 10:30 am how fast was Kiran jogging
Answer:
Kiran is jogging at 9.6 miles per hour.
Step-by-step explanation:
We can find the speed of Kiran as follows:
[tex] v = \frac{x}{t} [/tex]
Where:
v: is the speed =?
x: is the distance = 24 miles
t: is the time
If Clare and Kiran started walking at 8 am and they get to their destination at 10:30 am, then the time is:
[tex] t = 10:30 - 8:00 = (10 h + 30min*\frac{1 h}{60 min}) - 8 h = 2.5 h [/tex]
Then, the speed of Kiran is:
[tex] v = \frac{x}{t} = \frac{24 miles}{2.5 h} = 9.6 miles/h [/tex]
Therefore, Kiran is jogging at 9.6 miles per hour.
I hope it helps you!
It took Jaylon 27 minutes to run 3 miles. If he continued to run at the same rate, how far did he run in an hour
Answer:
6.66 miles
Step-by-step explanation:
Miles run in 27 minutes = 3 miles
Miles run in 1 minute = 3÷27 miles = [tex]\frac{1}{9}[/tex]
1 hour = 60 minutes
Therefore,
Miles run in 60 minutes = [tex]\frac{1}{9}[/tex] × 60
= [tex]\frac{20}{3}[/tex] miles OR 6.66 miles

If the triangle were reflected across the x-axis, then translated four units to the left,
what would be the value of the x-coordinate of point B?
When the triangle is reflected across the x-axis, then point B would be (6, -6), but when it's also translated four units to the left, it will be (2, -6).
When you reflect something across an axis, then a point you recall will have the x or y value have the opposite sign (i.e. 6 would become -6 across the x-axis and vice versa).
When you translate something across the graph, you are adding to the x value when shifting to the right, subtracting from the x value when shifting to the left, adding to the y value when shifting upward, and subtracting from the y value when shifting downward.
∴, B = (2, -6).

Line segment has endpoints A(-4, -10) and B(-11, -7). To find the x-coordinate of the point that divides the directed line segment in a ratio, the formula was used to find that . What is the x-coordinate of the point that divides into a 3:4 ratio? -7 -5 -3 -1
Answer:
The x-coordinate is -7
Step-by-step explanation:
We can use the internal division formula to find this;
That will be;
(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
