Your neighbor subscribes to Play-All-Day television service that charges a $20 installation fee and $15 per month. You have a similar plan through The Best Company television service and you paid a $32 installation fee and $12 per month. WRITE AND SOLVE an equation to determine the month when you would pay the SAME total amount as your neighbor for television service
Answer:
4monthsStep-by-step explanation:
Play-All-Day television service
the Modell for the cost is given as
y=mx+c
y=15x+20------------1
where x is the number of months
The Best Company television service
the Modell for the cost is given as
where x is the number of months
y=mx+c
y=12x+32------------2
equating 1 and 2 we can solve for x, we have
15x+20=12x+32
15x-12x=32-20
3x=12
divide both sides be 3
x=12/3
x=4
the number of months is 4months
HELP ME Rachel finished a meal at a diner and received a bill for $10.99. She charged the bill along with a 15 percent gratuity to her credit card. What is the total amount she charged to her credit card? $11.14 $12.64 $13.19 $13.73
Answer: $12.64
Step-by-step explanation:
From the question, we are informed that Rachel finished a meal at a diner and received a bill for $10.99 and that she charged the bill along with a 15 percent gratuity to her credit card.
The total amount she charged to her credit card will then be:
= $10.99 + (15% × $10.99)
= $10.99 + (0.15 × $10.99)
= $10.99 + $1.6485
= $12.6385
= $12.64
the selling price of 12 eggs is equal to the cost price of 15 eggs. find the profit percent
Answer:
I believe it would be 25% profit
Step-by-step explanation:
Answer:
ok first thing multiply 15 by the cost of each egg the amount you'll get will be equal to the 12 eggs he sold then check the original price that each egg is supposed to be sold at and multiply it by 12 then subtract the selling price minus the original price to get your profit so to get percentage profit equals profit over original price * 100%

Y=x^2-12x+46
(Find the vertex, show steps )
Answer:
(6, 10)Step-by-step explanation:
Vertex form of an equation of a quadratic function is y=a(x-h)²+k, where vertex is (h, k)
We can find h and k by comleting the square:
[tex]y=x^2-12x+46\\\\y=x^2-2\cdot x\cdot\underline6+6^2-6^2+46\\\\y=\underline{x^2-12x+6^2}-36+46\\\\y=(x-6)^2+10\quad\implies\quad h=6\,,\ \,k=10\,,\ \,a=1[/tex]

The residents of a city voted on whether to raise property taxes. The ratio of yes to no votes was 7 to 4 of there 10,208 votes how many no votes are there
Answer: the number of no votes =3712
Step-by-step explanation:
Given: The ratio of yes to no votes was 7 to 4.
Let 7x = Number of resident said yes, 4x = Number of resident said No
Total votes = 7x +4x=11x
As per given, Total votes =10,208
[tex]11x = 10208\\\\\Rightarrow\ x=\dfrac{10208}{11}\Rightarrow\ x=928[/tex]
So, the number of no votes = 4(928)=3712
Hence, the number of no votes =3712

HELO PLEASE WILL GIVE BRAINLIEST Which series of transformations will map the trapezoid onto itself?
reflection over the x-axis, then a rotation 180° counterclockwise about the origin
reflection over the y-axis, then a rotation 180° counterclockwise about the origin
o reflection over the line y = x, then a rotation 90° counterclockwise about the point (0, 2)
O reflection over the line y = 2, then a rotation 90° counterclockwise about the point (0, 2)
Answer:
Step-by-step explanation:
In order to map the trapezoid onto itself, reflect the trapezoid over the x-axis, then rotate trapezoid by 180° in counterclockwise about the origin.
For the image of a figure to overlap with itself, the amount by which the figure should be rotated is?For the image of a figure to overlap with itself, the figure should be rotated by 360°
We have a trapezoid as shown in the image.
In order to map the trapezoid onto itself -
Reflect the trapezoid over [x] axis.Now, rotate it counter - clockwise by 180 degreesTherefore, in order to map the trapezoid onto itself, reflect the trapezoid over the x-axis, then rotate trapezoid by 180° in counterclockwise about the origin.

What is the equation of the line that passes through the point (-8, 1) and has a slope
of -3/4
Answer:
y - 1 = -3/4(x + 8)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Step-by-step explanation:
Step 1: Define
Point (-8, 1)
Slope m = -3/4
Step 2: Write equation
y - 1 = -3/4(x + 8)

A car initially at rest accelerates at 10ms2. The car’s speed after it has traveled 25 meters is what?
Answer:
22.4 m/s
Step-by-step explanation:
Given:
Δx = 25 m
v₀ = 0 m/s
a = 10 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (0 m/s)² + 2 (10 m/s²) (25 m)
v = 22.4 m/s
The average person's speed when riding a bike along a street is 18 kilometers per hour. What conversion factor can be used to convert this speed to meters per hour? StartFraction 1 kilometer Over 1,000 meters EndFraction StartFraction 1 meter Over 1,000 kilometers EndFraction StartFraction 1,000 meters Over 1 kilometer EndFraction StartFraction 1,000 kilometers Over 1 meter EndFraction
Answer:
The conversing factor is [tex]\dfrac{1}{1000}\ km[/tex].
Step-by-step explanation:
The average speed of a person is 18 km/h.
We need to convert the speed to meters/hour.
We know that,
1 km = 1000 m
or
[tex]1\ m=\dfrac{1}{1000}\ km[/tex]
So,
[tex]18\ \dfrac{km}{h}=18\times \dfrac{1000\ m}{h}\\\\=18000\ m/h[/tex]
So, the conversing factor is [tex]\dfrac{1}{1000}\ km[/tex].
