Answer:
It takes the printer 20 minutes to print a banner
Step-by-step explanation:
Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.
So we can write the following two equations involving the total amount of time that takes to print in the two cases:
We can solve for the unknown "p" by subtracting term by term in the equation set above:
So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:
So, it takes 20 minutes to print a banner.
- What is the range of the given function?
- (–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)
- A {x | x = –5, –4, –2, 0, 2}
- B {y | y = –9, –3, 0, 5, 7}
- C {x | x = –9,–5,–4,–3,–2,0,2,5,7}
- D {y | y = –9,–5,–4,–3,–2,0,2,5,7}
- The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
- The range is the resulting y-values we get after substituting all the possible x-values.
- The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)Substitute different x-values into the expression for y to see what is happening. (Ask yourself: Is y always positive? Always negative? Or maybe not equal to certain values?)Make sure you look for minimum and maximum values of y.
