Answer:
one solution with a y value of 5
Step-by-step explanation:
/| x+y-4 = 0| x-y-6 = 0
We try to solve the equation: x+y-4 = 0
x+y-4 = 0 // - x-4
y = -(x-4)
y = 4-x
We insert the solution into one of the initial equations of our system of equations
We get a system of equations:
/| x+x-6-4 = 0| y = 4-x
2*x-10 = 0 // + 10
2*x = 10 // : 2
x = 10/2
x = 5
We insert the solution into one of the initial equations of our system of equations
For y = 4-x:
y = 4-5
y = -1
We get a system of equations:
/| y = -1| x = 5
Answer:
Subtract 100 then take 10% off
Step-by-step explanation:
Answer: The surface area of the cube is 385 mm^2.
When we are finding the surface area of a shape, we need to add up all the areas of each face. In this case, there are 6 faces.
Each face is the shape of square with sides of 8 mm. So the area of each face is 8 x 8 = 64 square mm.
Since we have 6 faces, we will multiply 64 by 6 to get 384 mm^2 in all.
In mathematics, sometimes the word 'of' means 'multiply'.
Simplify.
So, 1/2 is the answer.

Answer: (18, 2)</h3>
We find this answer by multiplying the original coordinates by the scale factor 2.
The old x coordinate 9 doubles to 9*2 = 18, which is the new x coordinate.
The old y coordinate 1 doubles to 1*2 = 2, which is the new y coordinate.
The dilation rule can be stated as 
, which means
