Answer: The answer is = 2x^2 -11x-40
Step-by-step explanation: a= 2x, b=5, c= x, d =8
= 2xx + 2x (-8) + 5x +5(-8)
+ (-a)=-a
then simplify =2xx-2 -8x+5x.8
2xx=2x^2
2.8x=16x
5.8=40
=2x - 16x + 5x- 40
Answer:
$90000
Step-by-step explanation:
From the pie chart,
Let the total annual income = $y
The percentage of housing = 28 %
The percentage of clothing = 14 %
The combined percentage of housing and clothing = 28+14 = 42 %
If the amount spent on both housing and clothing combined = $ 37800
Therefore,
y(42/100) = 37800
Solve for y
42y = 37800×100
42y = 3780000
y = 3780000/42
y = $90000
Hence, the total annual income is $90000
Answer:
quadrant 1 - (2,4)
quadrant 2 - (-3,4)
quadrant 3 - (-1, -5)
quadrant 4 - (6, -1)
Step-by-step explanation:
quadrant one consists of both x and y being positive.
quadrant two being the x is negative but the y is negative.
quadrant 3 has its x and y both negative.
finally, quadrant 4 has its x positive, but y is negative.
Four? Isn't it stated in the question? Unless I am assuming wrong.
Answer: $252.68
Step-by-step explanation:
Find 12.75% of 249 by using formula T= A + (A•I/100)
T=249+(249•12.75)/100)= 31.75 (taxes)
Then add taxes to room cost;
249+31.75= 280.75
Then you’d apply the coupon of 10% by using; Discount = Original Price x Discount %/100
Discount = 10% or 10/100=0.1
Discount = 280.75 x 0.1
= $28.08
Now you’d find the final price by;
Final Price = Original Price - Discount
Final Price = 280.75 - 28.075
Final Price = $252.68
