Answer:
Step-by-step explanation:
Remark
This is a right angle triangle.
Proof
a^2 + b^2 = c^2
a = 3
b = 4
c = 5
3^2 + 4^2 = 5^2
9 + 16 = ? 25
25 = 25
Area
The 2 smaller legs are perpendicular to each other.
Area = 1/2 a * b
Area = 1/2 * 3 * 4
Area = 6
Answer:
9/5
Step-by-step explanation:
solve the original equation for x
-4× + 3 = 1x +(-6)
-1x
-5x + 3 = -6
-3
-5x = -9
/-5
x = 9/5
CHECK
-4(9/5) + 3 = 1(9/5) +(-6)
-21/5 = -21/5
Answer:
x = 35/22
y = 3/22
Step-by-step explanation:
y= 2/5x-1/2 ................(1)
y=-1/3x+2/3 ...............(2)
10*(1)
10y = 4x -5 ...................(1A)
3*(2)
3y = -x +2 ....................(2A)
To find intersection, solve for y & x
4(2A) + (1A)
12y+10y = -4x+4x +8-5
22y = 3
y = 3/22
Substitute in (1)
3/22 = 2/5x -1/2
multiply by 110
15 = 44x - 55
70 = 44x
x = 70/44 = 35/22
10/7 7/13 3/5 is probably some of the answer
