Answer:
Never
Step-by-step explanation:
If two equations have the same slopes and the same y-intercepts they are equivalent to each other
Here's why:
The formula for a linear equation is y= mx +b
b= y- intercept
m= slope
m and b are only variable that have to be replaced by a number for the equation to be complete
Therefore, when m and b (or the slope and the y-intercept) of both equations are the same, the two equations are the same
The answer would be allrealnumbers, not nosolutions

True or false? 3a+15b is divisible by 3 for any values of a and b.
Answer:
true
Step-by-step explanation:
its TRUE :)
Answer:
False
Step-by-step explanation:
Take a=-1 and b=-1/7
-3+-15/7=-36/7 which is not divisible by 3. There are several other examples which I don't even need to prove
1. A worker in a company work 7 hours in a day, there are 22 working days in a month other than working hours each worker works 8 extra hours in a month, how many hours a worker is working in a full month?
Answer: A worker is working 162 hours in a month.
Step-by-step explanation:
Working hours per day = 7
Total working days = 22
Extra hours per month = 8
Total hours a worker works in a month = (Working hours per day) x (Total working days) +(Extra hours per month)
Total hours works in month = = 7 x22+8
= 154+8
= 162 hours
Hence, a worker is working 162 hours in a month.

What’s the mean,median,mode and range
Answer:
Mean=2.1
Median=2
Mode=1,2, and 3
Range=5
Step-by-step explanation:
Mean is all the numbers added up and then divided by the amount of numbers there are, so 0+1+0+2+3+1+3+5+4+2=21, and then 21 divided by 10=2.1
Median is lining all the numbers up least to greatest and then finding the middle number, which is 2.
Mode is the number that appears the most, and since 1,2,3 all appeared twice in the data, they are the mode.
Range is the highest number in the data subtracted by the lowest number in the data, so 5-0=0

Given: circle P with diameter RS TW
prove: RTW is isosceles
Answer:
Step-by-step explanation:
First, the RS is perpendicular to TW. That is paired with "Given".
Then arc mTR = arc mRW. This is paired with, "Diameter perpendicular to a chord bisects major arcs".
After that, chord TR = chord RW. You'll pair this up with "If arcs are =, chords are =".
Finally you'll pair Triangle TRW is isosceles with "Definition".
RS perpindicular TW Given
m RT= m RW Diameter perpindicular to chord bisects major arcs
TR = TW If arcs are =, chords are =
TRW is issocolees Definition
A sweater that is regularly priced at $25 is on sale for 25% off.
What is the amount of the discount?
What is the sale price?
What is the total price of the sweater including the 6.5% sales tax?
need help now plz
Answer:
Discount = 6.25
Sale Price = 18.75
6.5% tax = 1.21875
Final price = 19.96875 = 19.97
Step-by-step explanation:
25 x .25 = discount
25 - 6.25 = sale price
18.75 × 0.065 = tax
18.75 + 1.21875 = final price

Given the function
[tex]y=-720t\:+\:3600[/tex]
To determine
What is the domain of the function y=-720t + 3600
We know that the domain of the function is the set of input argument values for which the function is real and defined.
Given the function
[tex]y=-720t\:+\:3600[/tex]
From the given function, it is clear that the function has no undefined points nor domain constraints.
Therefore, the domain of the function is

Solve 2x^2 + x - 15 = 0
Step-by-step explanation:

There are various methods of solving quadratic equations. They are as follows :
Solving a quadratic equation by factorisation method : In this method , the second order of polynomial ax² + bx + c is factorised and expressed as the product of two linear factors. Then each linear factors is separately solved to get the required solutions of the equation by applying zero factor property. In zero factor property , if p • q = 0 then either p = 0 or q = 0 .In other words , if the product of two numbers is 0 , then one or both of the numbers must be zero.Solving a quadratic equation by completing the square : In this method , we transpose the constant term ( c ) to R.H.S , then L.H.S to expressed as perfect square expression.Solving a quadratic equation by using formula : In solving a quadratic equation of the form ax² + bx + c = 0 by completing the square , we obtain two roots of x , which are :[tex] \sf{ \frac{ - b + \sqrt{ {b}^{2} - 4ac } }{2a}} [/tex] and [tex] \sf{ \frac{ - b - \sqrt{ {b}^{2} - 4ac } }{2a}} [/tex]. These roots can be written as [tex] \sf{x = \frac{ - b \: ± \: \sqrt{ {b}^{2} - 4ac} }{2a}} [/tex] where a is the coefficient of x² , b is the coefficient of x and c is the constant term. We use this formula to find the required solutions of the given quadratic equation.Hope I helped! ツ

The solutions to the quadratic equation [tex]2x^{2} + x - 15[/tex] are x = 2.5 and x = -3.
Given data:
The quadratic equation is represented as [tex]2x^{2} + x - 15[/tex].
Now, the roots are determined as:
[tex]x_{1}=\frac{-b+\sqrt[]{b^{2}-4ac} }{2a}[/tex]
[tex]x_{2}=\frac{-b-\sqrt[]{b^{2}-4ac} }{2a}[/tex]
The value of a = 2 , b = 1, and c = -1.5
Substituting the values in the equation:
[tex]x_{1}=\frac{-1+\sqrt[]{1^{2}-4*2*(-1.5)} }{2*2}[/tex]
So, the value of [tex]x_{1}=2.5[/tex].
[tex]x_{2}=\frac{-1-\sqrt[]{1^{2}-4*2*(-1.5)} }{2*2}[/tex]
The value of [tex]x_{2}=-3[/tex].
So, the roots are x = 2.5 and x = -3.
Hence, the quadratic equation is solved.

Oliver is training for a marathon. In practice, he runs 15 kilometers in 72 minutes. What is his speed in kilometers per hour?
Answer:
12.5 km/hr
Step-by-step explanation:
An hour is 60 minutes.
So 15km/72min = x km/60min
15*60 = 72*x
x = 12.5
Answer:
12.5 km/hr
Step-by-step explanation:
If he runs 15km in 72minutes,
15km/72min = .208333 km per minute
there are 60 minutes in a hour
.208333 km/min * 60min/hr = 12.5 km/hr

You can earn 15n dollars for mowing n lawns. How much do you earn for mowing 1 lawn? 7 lawn?
Money earned for mowing n lawns = 15 n
Money earned for mowing 1 lawn:
Put n = 1 in the equation:
[tex]15 n\\=15(1)\\=15[/tex]
So, Money earned for mowing 1 lawns = 15 dollars
Money earned for mowing 7 lawn:
Put n = 7 in the equation:
[tex]15 n\\=15(7)\\=105[/tex]
So, Money earned for mowing 7 lawns = 105 dollars
