Which situation represents a proportional function? A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee. B. Sandra's cell phone plan charges seven cents a minute. C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month. D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.
Step by step explanation
let x be the number of minutes and y be the total charges per month
A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee.
y=0.02x+10
B. Sandra's cell phone plan charges seven cents a minute.
y=0.07x
C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month.
y=0.05x-5
D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.
y=0.06x+5

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0
Hope this helps :)

Answer:
I believe it is 1.) SAS (angle side angle) 2.) SSA (side side angle), but can not be proven as a postulate, so not enough information, 3.) SAS (side angle side) 4.) SSS (side side side)
Step-by-step explanation:
Answer:
1) ASA (angle side angle postulate)
2) not enough information
3)SAS (side angle side)
4) SSS (side side side)
1) Triangle T1 is transformed into triangle T2 by
a. dilation with scale factor of 1/2
b. reflection over the y-axis
c. translation
2) and triangle T2 is transformed into trinagle T3 by
a. dilation with scale factor 1/2
b. reflection over the x-adis
c. rotation
Answer:
1) The correct option is;
b. Reflection over the y-axis
2) The correct option is;
a. Dilation by a scale factor of 1/2
Step-by-step explanation:
1) The rule for reflection over the y-axis is given as follows;
Given the point of the preimage before the reflection = (x, y), the point of the image after the reflection will be (-x, y)
The coordinate of a point on T1 is (-2, 4). The coordinate of similar point in T2 is (2, 4) which satisfies the rule for reflection over the y-axis
2) The length of a side in triangle T2 is given by the formula for finding the length, l, of segments between coordinate points as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Point 1, (x₁, y₁) = (2, 4)
Point 2, (x₂, y₂) = (6, 2)
The length = √((2 - 4)² + (6 - 2)²) = 2·√5
The length of the corresponding side in T3 is given as follows;
Point 1, (x₁, y₁) = (1, 2)
Point 2, (x₂, y₂) = (3, 1)
The length = √((1 - 2)² + (3 - 1)²) = √5
The length of of a side T3 = 1/2 of the length of a side of T2
Therefore. triangle T2 is transformed into triangle T3 by dilation with a scale factor of 1/2.

If water flows through a pipe at a rate of 6 milliliters per hour, how wil I express this rate of flow in pints per day?
Answer:
0.304 pints per day
Step-by-step explanation:
Here, we want convert
if 6 milliliters flow in an hour , then in a day which is 24 hours, the amount that will flow is 24 * 6 = 144 milliliters in a day
so we need to convert this to pint
mathematically;
1 pints= 473.176 ml
x pints = 144 ml
x =
144/473.16 = 0.304 pints per day

The total number of miles, d, Elise walks in n hours can be modeled by the equation d = ns. Her rate stays the same each hour. Which represents the number of miles Elise walks per hour?
Answer:
Step-by-step explanation:
Given the number of miles Elise walks in n hiurs modeled by the equation;
d = ns
The number of miles he walks per hour is expressed by substituting n =1 into the equation to have;
d = ns
d = (1)s
d = s
Hence the number of miles he walked per hour is expressed as d = s

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!
