Answer: or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that (second equation), you can substitute it into the first equation and solve for the variable y:
Now you need to substitute into the second equation to calculate the value of the variable x. Then:
Then, the solution is:
or (1,1)
Answer:
The correct answer is:
It is a linear function because there is a constant rate of change in both the input and output values.
Step-by-step explanation:
Given table is:
Input
(x) Output
(y)
−2 7
−5 4
−8 1
−11 −2
It can clearly be observed that the values for x and y are changing with the same rate.
In case of x, -3 is added to the previous input to get the next input.
Similarly, in case of y, the next output value is obtained by subtracting 3 from the previous value.
Hence,
The correct answer is:
It is a linear function because there is a constant rate of change in both the input and output values.
Answer:
-1
Step-by-step explanation:
The slope formula when given two points is
m = ( y2-y1)/(x2-x1)
= (4 - -1)/(-1 -4)
= (4+1)/(-5)
= 5/-5
=-1
Answer:
8, -8 and 1
Step-by-step explanation:
It is 40 1/2 because it's a mixed number<span />
