Answer:
(0,2)
Step-by-step explanation:
solve by addition/elimination
2x + 3y= 6
–3x + 5y = 10
multiply first equation by 3 and second one by 2 to eliminate x)
6x+9y=18
-6x+10y=20 (add the two equations)
6x+9y-6x+10y=38
19y=38
y=38/19=2
2x+3y=6
2x=6-6
x=0
Answer:
a
Step-by-step explanation:
41 inches
B.
4 inches
C.
38 inches
D.
30 inches
Answer:
30
Step-by-step explanation:
the answer has to be greater than 6 and less than 36
15+21=36, 21-15=6
In triangle ABC, where AB = 15 inches, BC = 21 inches, the possible length of AC is 30 inches based on the triangle inequality theorem that states the sum of two sides of a triangle must be greater than the length of the remaining side. The length of AC should be between the sum and the difference of AB and BC. Only option D (30 inches) falls in this range.
To find out the possible lengths of side AC in triangle ABC, we can apply the triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. Here, AB = 15 inches and BC = 21 inches. Therefore, AC must be less than the sum of AB and BC(15 + 21 = 36 inches) and more than the difference of AB and BC(21 - 15 = 6 inches).
So, the length of AC must be between 6 inches and 36 inches. Looking at the options, only D. 30 inches falls within this range. As a result, 30 inches could be the length of side AC in triangle ABC.

Answer:
31.41 ft²
Step-by-step explanation:
Heron's formula is useful when you have the three side lengths.
A = √(s(s -a)(s -b)(s -c)) . . . . sides are a, b, c and s = (a+b+c)/2
Using the given side lengths, we have ...
s = (8 +8.4 +13.5)/2 = 29.9/2 = 14.95
A = √(14.95(14.95 -8)(14.95 -8.4)(14.95 -13.5)) = √(14.95×6.95×6.55×1.45)
A = √986.81399375 ≈ 31.41 . . . . square feet
Answer:
s= (-3, 10)

hundred.
Answer:
let monday be a = 800 (nearest 100)
let tuesday be b = 700 (nearest 100)
a+b = 800 + 700 = 1500
a+b = 1500
Answer:
it is point B
Step-by-step explanation:
because im smart
Answer:
Point B
Step-by-step explanation:
√11 is 3.3
And A is about 2. Something and inbetween D and E is 4 which means C will be 3.5
So it leaves it at B
