I need help with this
Answer: 500
Step-by-step explanation: use the equation y=mx+b.
B = cost of the plan per month
X = number of minutes
M = price per minute
The first plan is a flat rate of $25 a month. Whereas the second is $10 plus $0.05 a minute.
Plug in the answers until you get a price that is equal to $25.
Y = 0.05(300) + 10
Y = 25
therefore after 300 minutes the other plan is cheaper

Find the area of the surface. The part of the surface z = xy that lies within the cylinder x2 + y2 = 36.
Answer:
Step-by-step explanation:
From the given information:
The domain D of integration in polar coordinates can be represented by:
D = {(r,θ)| 0 ≤ r ≤ 6, 0 ≤ θ ≤ 2π) &;
The partial derivates for z = xy can be expressed as:
[tex]y =\dfrac{\partial z}{\partial x} , x = \dfrac{\partial z}{\partial y}[/tex]
Thus, the area of the surface is as follows:
[tex]\iint_D \sqrt{(\dfrac{\partial z}{\partial x})^2+ (\dfrac{\partial z}{\partial y})^2 +1 }\ dA = \iint_D \sqrt{(y)^2+(x)^2+1 } \ dA[/tex]
[tex]= \iint_D \sqrt{x^2 +y^2 +1 } \ dA[/tex]
[tex]= \int^{2 \pi}_{0} \int^{6}_{0} \ r \sqrt{r^2 +1 } \ dr \ d \theta[/tex]
[tex]=2 \pi \int^{6}_{0} \ r \sqrt{r^2 +1 } \ dr[/tex]
[tex]= 2 \pi \begin {bmatrix} \dfrac{1}{3}(r^2 +1) ^{^\dfrac{3}{2}} \end {bmatrix}^6_0[/tex]
[tex]= 2 \pi \times \dfrac{1}{3} \Bigg [ (37)^{3/2} - 1 \Bigg][/tex]
[tex]= \dfrac{2 \pi}{3} \Bigg [37 \sqrt{37} -1 \Bigg ][/tex]

What is -2 2/3 divide by -1/2
Answer:
16/3
Step-by-step explanation:
Answer:
5 1/3
Step-by-step explanation:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−8/3 ÷ −1/2
Applying the fractions formula for division,
=−8×2/3×−1
=−16/−3
Simplifying -16/-3, the answer is
=5 1/3

Solve the following system of equations using elimination.
5x+y=24
-5x-4y=-56
Answer:
x = 8/3 and y = 32/3
Step-by-step explanation:
Add the two equations, getting -3y = -32, thus y = 32/3
Sub for y in first equation, getting 5x + 32/3 = 24
5x = 40/3
x = 8/3
a graph represents a relation that is also a function if only and if every ___ intersects the graph ___ once
Answer:
A graph represents a relation that is also a function if only and if every vertical line intersects the graph at most once.
Step-by-step explanation:
The vertical line test should be used to get an idea about the nature of a graph whether it represents a function or not. A vertical line must not intersect the graph multiple times as it would violate the definition of a function.
If a vertical line intersects the graph multiple times, it means the graph is having the same repeated inputs, which is against the definition of a function. A function can not have repeated input values.
Thus, we conclude that a graph represents a relation that is also a function if only and if every vertical line intersects the graph at most once.
Select the correct graph of the function y = –1/8(x – 1)2 – 4 below.
Question 8 options:

C)
image
D)
image
Step-by-step explanation:
The given function is :
[tex]y=\dfrac{-1}{8}(x-1)^2-4[/tex] ...(1)
It is an equation of parabola. The vertex form for equation of parabola is given by :
[tex]y=a(x-h)^2+k[/tex] ...(2)
Here,
Vertex = (h,k), axis = h and rate = a
From equation (1) and (2) :
a = -1/8, h = 1 and k = -4
The atached graph shows the graph for the given equation.
The coordinates of the turning point of the parabola whose
equation is y = x² - 6x + 8
Answer:
y=×2-6×+7 is the answer

What is the area of this quadrilateral?
10
OA. 130 square feet
B. 50 square feet
)C. 80 square feet
O D. 30 square feet
Answer:
C. 80
Step-by-step explanation:
5x10x.5=25
25x2=50
3x10=30
50+30=80
Answer:
C
Step-by-step explanation:
Split the shape into normal shapes such as a rectangle and two triangles
use there formulas for area for each shape
rectangle L x W
10 x 3 = 30
for triangles it’s side a times the base divided by 2
5 x 10 / 2 = 25
so it’s 50 because there is two triangles
add 50 and 30
so it’s 80ft so C
The forces exerted on an object are shown.
A box has an arrow pointing right labeled 6 N and an arrow pointing left labeled F.
If the object moves right, which of the following is a possible value of F?
5 N
6 N
7 N
8 N
Answer:
So you have a box, with weight Wb and you have a right force of 6N and a left force of Fl
With sum of forces you get that to maintain equilibrium the force Fl must be 6 therfore to maintain moving right the left force must be 5N
Rate positively and give brainlist
Answer:
The answer is 5n
Step-by-step explanation:
Since the force on the right would have to be greater, and the force on the right is 6n, the left force would have to be less. Therefore, the answer is 5n.

Write an equation for the line that passes through the point -3,2 and is parallel to line 4X + 2Y= -10
9514 1404 393
Answer:
2x +y = -4
Step-by-step explanation:
The equation of the given line can be simplified by dividing all of the numbers by 2:
2x +y = -5
The parallel line can have the same coefficients of x and y, but will have a different constant. The constant will be appropriate to the given point, so will be ...
2x +y = constant
2(-3) +(2) = constant = -6 +2 = -4
The parallel line is ...
2x +y = -4
Which of the following is an equivalent expression to 2x+2x+3y+y
A.4x + 2y
B.4xy
C.x+y
D.4x + 4y

Step-by-step explanation:
2x + 2x = 4x
3y + y = 4y
So, 4x + 4y is the answer!

4(x-3)=9 what is the first step
Answer:
x= 5.25
Step-by-step explanation:
You have to get x alone, so do inverse operations.
(Basically, reverse what it is)
4(x-3)=9
divide 4 by both sides to get rid of 4 on left side
9/4 = 2.25
(x-3) = 2.25
Now add 3 to both sides, to get x alone
2.25 + 3 = 5.25
x=5.25
Check work
4(5.25-3) = 9
4(2.25) = 9
9=9
