Answer:
y = 5/8 x
Step-by-step explanation:
Since it goes through the origin, the y intercept is zero
Answer:
<u><em>y = -5x + 10</em></u>
Step-by-step explanation:
<em>We know the slope-intercept form is :-</em>
<em>y = mx + b</em>
<em></em>
<em>Now, convert it into that form.</em>
<em>25x + 5y = 50</em>
<em>5y = -25x + 50</em>
<u><em>y = -5x + 10</em></u>
You would do 60 seconds multiplied by 24 hours in a day which would be 1440 beats then you would multiply by the number of days in a year which is 365 then you would get the awnser of 525,600 beats per year.
Answer: 16y² - x²
Step-by-step explanation: The - sign means a difference, so the choices with + signs are eliminated (though 64x² and 9 are squares)
10 is not a square so that one is eliminated (though the y² and the 4x² are squares)
16 is the square of 4, y² is the square of y, and x² is the square. That expression shows a difference of squares.
The ratio of males to females is 1.4 : 1, so the fraction of the total that is made up of males is 1.4/(1.4 + 1) = 1.4/2.4 = 7/12.
There were (7/12)*475 ≈ 277 males at the party.
There were 475 - 277 = 198 females at the party.
