Answer:
121
Step-by-step explanation:
31+90 = 121
180 - 121 = 59
180 - 59 = 121
Answer:
x=1
Step-by-step explanation:
slope AB = (7-5) / (3 - -1) = 2 / 4 = 1/2
slope CD = (23-11) / (x-7) = 12 / (x-7)
12 / (x-7) = - 2 ... perpendicular to AB slope 1 = - 1/slope 2
-2 (x-7) = 12
-2x + 14 = 12
-2x = -2
x = 1
Answer:
810
Step-by-step explanation:
9 x 10 = 90
9 x 90= 810
<u><em>PLZ MARK BRAINLIEST!</em></u>
Given a quadratic equation 
, we define the discriminant as
The number of real solutions of the equation depend on the sign of 
:
- If
the equation has two solutions - If
the equation has one double solution - If
the equation has no real solutions
In this case, we have
And so this equation has no real solutions.

Answer:</h3>
- sticker: $12,620
- dealer's cost: $10,712
<h3>
Step-by-step explanation:</h3>
The total cost of options is the sum of their individual costs.
total options = $542 +140 +318 +580 = 1580
The sticker price is ...
sticker price = base price + total options + destination charge
= $10600 +1580 +440
sticker price = $12,620
The dealer cost is ...
dealer cost = 82% × base price + 100% × total options + destination charge
= 0.82·$10600 +1580 +440
dealer cost = $10,712
