Answer:
The correct option is (B)
(B) x-y = 6 , 3x+4y = 4
Step-by-step explanation:
As we can see in the graph given below, both lines intersect at (4, -2), which should be the solution of given equations:
Find the values of x and y for (B);
x - y = 6 ⇒ (i)
3x + 4y = 4 ⇒ (ii)
Lets consider equation (i)
x - y = 6
x = 6 + y
Substitute in equation (ii)
3(6+y) + 4y = 4
18 + 3y + 4y = 4
7y = -14
y = -2
Substitute in equation (i)
x - (-2) = 6
x + 2 = 6
x = 6 - 2
x = 4
As solution of part C is also (4, -2), it represents the graph
You can also find the (x, y) for other options the similar way, which will show you they don't have the same value
Answer:
7m
Step-by-step explanation:
-9(-5k + 3m) + 9m - 5(-5m + 9k)
Distribute
45k -27m +9m +25m -45k
Combine like terms
45k -45k -27m+9m+25m
0k + 7m
7m
FORMULA:
Volume of pyramid = L × B × H/3
Height of pyramid = 3V/area of base(L × B)
ANSWER:
So, we have to just plug the respective value.
Height of given pyramid = √(22.1² - 14²)
- √(488.41 - 196)
- √292.41 = 17.1m
Now, Volume of given pyramid = 28 × 28 × 17.1/3
