Answer:
I got -64
Step-by-step explanation:
The begging multiplication is 0 and subtract -7 is becomes just -7 then add 3 and it is -4 to the third power is -64
Let the two numbers be represented by x and y. The problem statement gives rise to two sets of equations.
x - y = 0.6
y/x = 0.6 . . . . . . . assuming x is the larger of the two numbers
or
x/y = 0.6 . . . . . . . assuming y has the larger magnitude
The solution of the first pair of equations is
(x, y) = (1.5, 0.9)
The solution of the first and last equations is
(x, y) = (-0.9, -1.5)
The pairs of numbers could be {0.9, 1.5} or {-1.5, -0.9}.
Answer:
A. The graph is a line that goes through the points (9,0) and (0,6).
Step-by-step explanation:
Given
![4x + 6y = 36](https://tex.z-dn.net/?f=4x%20%2B%206y%20%3D%2036)
Required
Select the true options
![(a)\ (9,0)\ and\ (0,6)](https://tex.z-dn.net/?f=%28a%29%5C%20%289%2C0%29%5C%20and%5C%20%280%2C6%29)
This implies that"
![(x_1,y_1)= (9,0)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%3D%20%289%2C0%29)
![(x_2,y_2)= (0,6)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%3D%20%280%2C6%29)
So, we have: ![(x_1,y_1)= (9,0)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%3D%20%289%2C0%29)
![4x + 6y = 36](https://tex.z-dn.net/?f=4x%20%2B%206y%20%3D%2036)
![4 * 9 + 6 * 0 = 36 + 0 = 36](https://tex.z-dn.net/?f=4%20%2A%209%20%2B%206%20%2A%200%20%3D%2036%20%2B%200%20%3D%2036)
So, we have: ![(x_2,y_2)= (0,6)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%3D%20%280%2C6%29)
![4 * 0 + 6 * 6 = 0 + 36 = 36](https://tex.z-dn.net/?f=4%20%2A%200%20%2B%206%20%2A%206%20%3D%200%20%2B%2036%20%3D%2036)
<em>Hence (a) is true.</em>
