Answer:
x=-6 y=7
Step-by-step explanation:
8x+5y=-13; x+y=1
Isolate x and substitute
(-13-5y)/8 +y=1
Isolate y
y=7
substitute y=7
(-13-5*7)/8=-6

13.018
Step-by-step explanation:
14.15 minus 8 percent = 13.018
Answer:
The response that are true are:
- linear function has a constant additive rate of change, while a nonlinear function does not.
Since in linear function the rate of change is always equal as for a linear function we get a equation of line such that the slope is same.
- On a graph, the function must be a straight line to be linear.
Liner means there is a straight line of the function.
( Also it need not be true that the independent variable increases by 1.
There may be change of some other quantity in independent variable )
Answer:
C
Step-by-step explanation:

To solve for x, we have to remember to isolate the variable.
For 1/2, we can make that 0.5, since their values are equivalent. Our equation:
Let's distribute the 0.5 first.
Now, let's simplify the right side of the equation. We have to distribute the negative to 3x and 1.
Then, we simplify the entire expression.
Our equation now:
Let's add 3x to the right and 3x to the left to simplify the -3x on the right side of the equation.
Let's do the same thing we did in Step 3 to 1.5. Subtract 1.5 on both sides of the equation.
Finally, we divide both sides by 6 to isolate x.
