Which equation represents the cost of the high-efficiency washing machine over a given number of years?
Which equation represents the cost of the standard washing machine over a given number of years?
After how many years of use would the washing machines cost the same amount?
Which washing machine would be the more practical purchase if kept for 9 years?
heres ur answer:
i) y = 25x + 500
ii) y = 30x + 400
iii) the washing machines would cost the same amount after 20 years of use
iv) standard machine

How are greater than > and greater than or equal ≥ to similar?
how are they different?
Answer:
They are different because the greater than or equal to symbol is used when something is greater than or equal to a number and the greater than symbol is used only for numbers greater than for example 5 is greater than or equal to 5 but 5 is not greater than 5.
Step-by-step explanation:
I hope that helped :)
Answer:
They are similar because they both show if a number is greater then another, but > doesn't mean that that number could be equal.

What is the quotient of-27.375 divided by 7.5?
A. -3.65
B. -0.365
C. 0.365
D. 3.65
God bless all! :)
Answer:
-3.65 *Can I have brainliest plz?
Step-by-step explanation:
Shift the decimals of both 27.375 and 7.5 to the right by 1 decimal place. (This is needed to convert 7.5 to 75, since long division must divide by a whole number.)
273.75\div 75273.75÷75
Use the algorithm method.
3 . 6 5
7 5 | 2 7 3 . 7 5
2 2 5 .
4 8 . 7
4 5 . 0
3 . 7 5
3 . 7 5
Now consider the signs. One number is positive, and the other number is negative. Therefore, the result will be negative.
-27.375,7.5 \rightarrow \text{Negative}−27.375,7.5→Negative
Therefore, -27.375\div 7.5=-3.65
-3.65

A- 80mm
B- 250mm
C- 100mm
D- 1 240mm
Answer:
A
Step-by-step explanation:
We can cross out the two sides that are the same in both shapes.
so that leaves the hypotenuse of 253 and the sides 231 & 104 of the square.
Because 253 is close to 231, it can be cancelled out and that leaves out the 104.
But we can take 20 away from the ~250 and ~230
100-20 is about 80

C. (2/5)(8/9)(1/3)(-2/7)
D. (-2/5)(-8/9)(1/3)(2/7)
PLEASE HURRY!!!!!!!!! God bless all and stay safe!! :) :)
The product of (-2/5)(-8/9)(1/3)(2/7) is positive. so the correct option is (D)
WE are given the following the expression as;
A. [tex]\frac{2}{5}{\times}\frac{-8}{9}{\times}\frac{-1}{3}{\times}\frac{-2}{7}=\frac{-32}{945}[/tex]
This is a negative number, thus Option A is incorrect.
B.[tex]\frac{-2}{5}{\times}\frac{8}{9}{\times}\frac{-1}{3}{\times}\frac{-2}{7}=\frac{-32}{945}[/tex]
This is a negative number, thus Option B is incorrect.
C.[tex]\frac{2}{5}{\times}\frac{8}{9}{\times}\frac{1}{3}{\times}\frac{-2}{7}=\frac{-32}{945}[/tex]
This is a negative number, thus option C is incorrect.
D. [tex]\frac{-2}{5}{\times}\frac{-8}{9}{\times}\frac{1}{3}{\times}\frac{2}{7}=\frac{32}{945}[/tex]
This is a positive number, thus option D is correct.

Mark as brainliest :)
I'm not 100% if this is correct but I hope it is.
The width of the DNA in scientific notations will be 1.5x10⁻⁸ meter. The correct option is D.
What is scientific notation?Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation. It could be called scientific form.
A numerical indication of the operation of raising to a power that is placed above and to the right of a mathematical expression.
Given that the width of DNA is approximately 0.0000000025 meters wide. The number is multiplied by 6 then the answer in the form of the scientific notations will be written as:-
DNA width = 0.0000000025 x 6
DNA width = 0.0000000025 x 6
DNA width = 1.5 x 10⁻⁸ meter
Therefore, the width of the DNA in scientific notations will be 1.5x10⁻⁸ meter. The correct option is D.

PLS HELP WITH MY MATH
Answer:
1)yes the graph is a function,because it follows the 1 line rule.
2)The graph has a maximum, The graph is opened downward, which means its a maximum
3) the graph is increasing at (-2,0) and (2,0), because the graph starts to widen
4) the graph decreases at (0,4), because the graph ends there
5) the graph is linear because, because it follows the 1 line rule.
I hope this helps you :)
Answer:
It is a function. It is a function because none of the x-coordinates repeat/it passes the vertical line test. It does have a maximum. I know because the graph does not go up farther than y=4. I am not sure what it is asking here but I think that it is increasing on the x-axis as the graph travels further down. The graph is decreasing on both the y and x-axis because as the graph travels further down, both of them decrease I think. This is not linear. I know because it is quadratic, not linear and for it to be linear, the values would increase by the same amount every time and this graph does not apply to that.
