Answer:
One solution: x=6, y=7. (6, 7).
Step-by-step explanation:
y=x+1
y=2x-5
-----------
x+1=2x-5
1=2x-x-5
x-5=1
x=1+5
x=6
y=6+1=7
Answer:
A dependent variable
Step-by-step explanation:
is a variable whose value will change depending on the value of another variable, called the independent variable. Dependent variables are also known as outcome variables, left-hand-side variables, or response variables.
4^0=1
1-1=0
10*0=0
since when something is brought to the power of 0, it equals 1. Then when put into the equation the brackets = 0 therefore the whole equation equals 0
