Bryan spent 14 minutes on the phone while routing 7 phone calls. How many phone cells does Bryan have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells

How were greek city states formed
Answer:
Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands. These physical barriers caused population centers to be relatively isolated from each other. The sea was often the easiest way to move from place to place.

Find the perimeter of the above shape to the nearest whole number take pi as 22/7
The unshown part is 16cm
Answer:
60.
Step-by-step explanation:
I can't see the question above this and what information it gives, but If I'm not mistaken, that shape is a rectangle, so regardless of whether there's a piece of the last side missing, the sides across from each other are congruent in size.
So if the top is 14, then the bottom is 14, and since the left side is 16, then the side missing a piece adds up to 16.
(14*2) + (16*2) =
28 + 32 = 60.

Answer:
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.
Step-by-step explanation:
Given that:
x-4y = 2
2x+y = 12
For elimination, one of the variable is eliminated.
In this system,
we can either multiplying the first equation by 2 or second equation by 4.
Then we can add the equations.
By multiplying the second equation with 4 and then adding both equations, we can eliminate the variable y.
4(2x+y=12)
8x+4y=48
By adding
(x-4y)+(8x+4y)=2+48
7x=48
Hence,
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.

[tex]24a-3(2a-5)=51[/tex]
Step 1: Let's solve first so we can order it later.
[tex]24a-6a+15=51\\18a+15=51\\-15 -15\\\18a=36\\\\[/tex]
Divide 18 both sides.
[tex]a=2[/tex]
Ok so we have everything solved answer: a=2.
Now we need to order.
Step 1. Distribute 3.
Step 2. Combine like terms 24a and 6a.
Step 3. Subtract 15 from both sides.
Step 4. Divide both sides by 18.

7(x + 5) = -35
O
x = -10
x = 5
O x = -5
X = 0
Answer: x = -10
Step-by-step explanation:
7 (x + 5) = -35
Distribute 7 to x + 5
7 * x = 7x
7 × 5= 35
7x + 35 = -35
Subtract both sides by 35
7x = - 70
Divide both sides by 7
x = -10

Write an equation of the perpendicular bisector of the segment with the endpoints (8,10) and ( -4,2).
y =
Answer:
The required equation is:
[tex]y = -\frac{3}{2}x+9[/tex]
Step-by-step explanation:
To find the equation of a line, the slope and y-intercept is required.
The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.
Given points are:
[tex](x_1,y_1) = (8,10)\\(x_2,y_2) = (-4,2)[/tex]
We will find the slope of given line segment first
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{2-10}{-4-8}\\=\frac{-8}{-12}\\=\frac{2}{3}[/tex]
Let m_1 be the slope of perpendicular bisector then,
[tex]m.m_1 = -1\\\frac{2}{3}.m_1 = -1\\m_1 = \frac{-3}{2}[/tex]
Now the mid-point
[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\= (\frac{8-4}{2} , \frac{10+2}{2})\\=(\frac{4}{2}, \frac{12}{2})\\=(2,6)[/tex]
We have to find equation of a line with slope -3/2 passing through (2,6)
The equation of line in slope-intercept form is given by:
[tex]y = m_1x+b[/tex]
Putting the value of slope
[tex]y= -\frac{3}{2}x+b[/tex]
Putting the point (2,6) to find the y-intercept
[tex]6 = -\frac{3}{2}(2)+b\\6 = -3+b\\b = 6+3 =9[/tex]
The equation is:
[tex]y = -\frac{3}{2}x+9[/tex]
The equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is [tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex] and this can be determined by using the point-slope form of the line.
Given :
Endpoints -- (8,10) and (-4,2)
The following steps can be used in order to determine the equation of the perpendicular bisector:
Step 1 - First, determine the slope of the line that passes through points (8,10) and (-4,2).
[tex]\rm m =\dfrac{2-10}{-4-8}[/tex]
[tex]\rm m = \dfrac{8}{12}[/tex]
[tex]\rm m = \dfrac{2}{3}[/tex]
Step 2 - So, the slope of the perpendicular bisector is given by:
[tex]\rm m'm = -1[/tex]
[tex]\rm m' = -\dfrac{3}{2}[/tex]
Step 3 - Now, determine the midpoint of the line that passes through the points (8,10) and (-4,2).
[tex]\rm x = \dfrac{8-4}{2}=2[/tex]
[tex]\rm y = \dfrac{10+2}{2}=6[/tex]
Step 4 - So, the equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is:
[tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex]

Answer:
1. First choice
2. Image C
3. Fourth chioice
4. Third choice
5. First choice.
Step-by-step explanation:
First ScreenshotSolve the equation.
[tex] {x}^{2} - 9 = 0[/tex]
Use the difference of two squares formula.
[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]
[tex](x + 3)(x - 3) = 0 \\ x = 3, - 3[/tex]
Second ScreenshotA linear relationship already says it all. Find the graph that is NOT a curve. The only image that is not a curve and the graph straight forwards is the Image C aka A choice.
Third ScreenshotA nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.
Fourth Screenshot[tex]y = x + 3[/tex]
If we change the constant from 3 to 5 then we would get
[tex]y = x + 5[/tex]
The graph would shift up 2 units.
Last ScreenshotThe second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.
If the line intercepts more than a point then it is not a function.
If the line intercepts only a point then it is a function.

27 miles per gallon
D)
54 miles per gallon
Answer:
The unit rate = 27 miles per gallon.
Hence, option C is true.
Step-by-step explanation:
From the given line graph:
Taking two points
(2, 54)(6, 162)The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:54\right),\:\left(x_2,\:y_2\right)=\left(6,\:162\right)[/tex]
[tex]m=\frac{162-54}{6-2}[/tex]
Refine
[tex]m=27[/tex]
Therefore, the unit rate = 27 miles per gallon.
Hence, option C is true.

Find the common difference of the arithmetic
sequence 13,9,5,
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4
If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side
Answer:
[tex]x=9, AB=BC=AC=35[/tex]
Step-by-step explanation:
Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for
[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)
Solving for [tex]x[/tex], we get:
[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)
[tex]2x=6x-36[/tex] (Simplify)
[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]-4x=-36[/tex] (Simplify)
[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=9[/tex] (Simplify)
Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!
