Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10
I believe the answer is x^2-4x+1
(I did the problem in my head but it seems correct)
The formula of a slope m:
We have the points (0, -1) and (5, -2). Substitute:
<h3>Answer: The slope = -1/5</h3>
Answer:
the best answer would be 5
Step-by-step explanation:
If it's breadth is 6 then the circles should have the diameter 6 and radius = 3
now subtract the area of both circles from the area of rectangle
area of circle = π r²
= 3.14 x (3)²
= 3.14 x 9
= 28.26
this is area of one circle
so area of both circles = 2 x 28.26 = 56.52
now the area of shaded region = area of rectangle - area of both circles
area of shaded region = 60 - 56.52
= 3.48 <------ANSWER
