Answer:
3x^2-6x+3=0
x^2-2x+1=0
x^2-x-x+1=0
x(x-1)-(x-1)=0
(x-1)(x-1)=0
x=1,1
so x has only one answer
so it intersects only one time
We will use W, L, and T for the number of wins, losses, and ties, respectively.
Using the provided information, we can create the following equation for the points.
2W + 0L + 1T = 30
We also know that there are 10 losses, we we can say the following:
W + T + 10 = 28
Now we have two equations that have the variables W and T. We can solve this system using substitution.
2W + T = 30
W + T = 18
So the answer is A.
Answer:
$0.90 per pound
Step-by-step explanation:
Before the coupon credit, the total bill was $2.58 +0.75 = $3.33 for the 1.25 +2.45 = 3.7 pounds of fruit. The cost per pound is ...
... cost/pound = $3.33/(3.7 lb) = $0.90 /lb

Answer:
Step-by-step explanation:
Consecutive interior angles between parallel lines are supplementary.
Let's start with x.
(8x +40)° +(6x)° = 180°
14x +40 = 180 . . . . . . . . . divide by °, collect terms
14x = 140 . . . . . . . . . subtract 40
x = 10 . . . . . . . . divide by 14
__
We can use the same approach for y:
(7y)° +(3y -10)° = 180°
10y = 190 . . . . . . . . . . . divide by °, add 10, collect terms
y = 19 . . . . . . . . . . . divide by 10
Answer:
smaller: 30°
larger: 150°
Explanation:
1) Given: sinθ = 1/2
2) That is a notable value.
You know that sine ratio is 1/2 for angles 30° and 180 - 30° = 150°
3) Therefore the angles are: smaller= 30°, larger = 150°
