Answer:
If we are assuming that this is a direct variation, y would be equal to 99.
Step-by-step explanation:
To find this, we start with the base equation for direct variation.
y = kx
Now we find k by plugging in our original values for x and y.
y = kx
36 = k(4)
9 = k
Now that we have k, we can model the equation.
y = 9x
And we can use the value of 11 in the next equation to find y.
y = 9x
y = 9(11)
y = 99
Answer:
2.5
Step-by-step explanation:
Usually when you try and find the area you would multiply but you don't have one of the numbers to multiply, so what is the oppisite of multiplication? Divison. You would divide the area by the highth. so it would be 4.5 divided by 1.8. 4.5 divided by 1.8 equals 2.5. And to make sure your answer is correct you would multiply 1.8 times 2.5 wich does equal 4.5. The highth is 1.8, the Length is 2.5, and the are is 4.5
Question 6
(1 , 2) (3 , 2) (3 , 4)
Question 7
(4 , 0) (0 , -2) (4 , -4)
Answer:
No solution
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
Equation of the line A and equation of the line B are parallel lines, because the slope is the same
therefore
The system has no solution, because its graphs do not intersect
