It’s -3,-2 hope thiisssss helpsssss
Answer:
2.5 cm
Step-by-step explanation:
Rectangle A L x W = 40
Rectangle B L * W = 1/2 (40)
8 * W = 20
W = 2.5 cm
Here we must see which information about the graph of a linear relationship is given. The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.
<h3>
Linear relationships:</h3>
So we define a general linear relationship as:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this problem we know that:
- Originally, the sheet of ice is 2 meters thick.
- The thickness decays at a constant rate
- After 3 weeks, the thickness is 1.25 meters.
The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)
So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

Answer:
x=7
y=-1
Step-by-step explanation:
When the two equations are solved together, they form simultaneous equations.
x+y=6
x-y=8
Let us use the elimination method. if we add the two equations, we eliminate y.
2x=14
x=7
Let us substitute for the value of x obtained above.
x-y=8
7-y=8
y=7-8
y=-1
