Answer:
Y = 35 - x
Step-by-step explanation:
The two expenses for the phones is $40 and $25 per phone. It is sold for $100. The amount of earnings is the sale price of the phone minus the expense for the phone. Let x be the number of phones they sell and y be the earnings. The expression is:
Y = 100x - (40 + 25) times X
b.) the amount (in dollars) the company earns from each phone
Answer:
y = 2/3x + 2
Step-by-step explanation:
Slope intercept form is y=mx+b where m is the slope and b is the y intercept.
Given 2 points you can find the slope using (y-y1)/(x-x1)
m = (-2-4)/(-6-3) = -6/-9 = 2/3
To find b use one of the points and m and plug into the slope intercept form and then solve for b.
y=mx+b
4=2/3(3) + b
4=2 + b
b=2
Now we can write the final equation as : (plug m and b back in)
y = 2/3x + 2
Answer:
i think the given triangle is equilateral triangle because all side are equal.
5 1/2 - u = 9/4 U= 13/4
Basically you have to get the variable (u) by itself. Doing this by doing the opposite of what it’s doing to both sides of the equation.
