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)
we only need the x coordinates in this case
m = 3 and n = 4
x = 4(-4) + 3(-11)/(3 + 4)
x = (-16 -33)/7 = -49/7 = -7
Answer:
A. -7

3х + 2y = 14
3х - 2y = 10
Answer:
(4, 1 )
Step-by-step explanation:
Given the 2 equations
3x + 2y = 14 → (1)
3x - 2y = 10 → (2)
Adding the 2 equations term by term, eliminates y , that is
6x = 24 ( divide both sides by 6 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
3(4) + 2y = 14
12 + 2y = 14 ( subtract 12 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (4, 1 )
Please help me w the equation and please don’t take advantage of the points.
Answer:
y = 6x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 and given point (0, 4 ) ⇒ c = 4
y = 6x + 4 ← equation of line

Step-by-step explanation:
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).

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

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.

We are going to define two equations where b means bagels and m will be muffins, First equation: 10*b + 4*m = 13 Second equation: 5*b + 8*m = 14 From the second equation, we can isolate b: b = (14 - 8*m)/5 In the second equation 10*(14 - 8*m)/5 + 4*m = 13 2*(14 - 8*m) + 4*m = 13 28 - 16*m + 4*m = 13 28 -13 = 16*m - 4*m 15 = 12*m m = 15/12 = 1.25 Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8 So one bagel costs $0.8 and one muffin $1.25
Answer:
Muffins: $1.25
Bagels: $0.80

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
