Answer:
2x^2+x-36=0
(4,0)
2*4^2+4-15=21
Step-by-step explanation:
Answer: x<5
Step-by-step explanation:
If the circle was dark then it would be x is less than or equal to 5. But here, since the circle is open, that means that 5 is not a possible solution for x. The answer is x<5. Hope this helps!
Given parameters:
1. 
; find the LCM = 8
= 
= 
2. 
Make the fraction decimal;
= -2.4
So;
-2.4 + 15.3 = 12.9
Y=-9x+4
-9x represents the slope . 4 is the initial value/y-intercept
Answer:
Part 1 : y = 0.75x
Part 2 : $750
Step-by-step explanation:
Part 1
Worst Buy, a local electronics store, advertises a sale price of 25% off all televisions 42" or bigger. Model the sales price (original price minus discount) of those televisions, y, as a function of the regular price of the tv, x.
Let y be the sales price of the tv and x its regular price. Since its sales price = regular price - discount, and our discount is 25% of the sales price, that is 0.25x, we have
sales price = regular price - discount
y = x - 0.25x
y = 0.75x
Part 2: If the regular price of a 60" television is $1000, use the equation you came up with in part 1 to find the sales price of the item
Since the sales price, y = 0.75x,and x = regular price = $1000,
substituting x into y, we have
y = 0.75x
y = 0.75($1000)
y = $750
