Answer to Problem 5LC
The relationship equation of gift card purchased and spent is
The three combinations of gift card purchased is given as
Explanation of Solution
Given info:
The price of the gift card is either $10 or $25.
Consider the number of $10 gift card is
Consider the number of $25 gift card is
The amount spent for buying gift card is $285.
Formula used:
Show the standard form of equation as follows:
Here,
Calculation:
Find the relationship equation of gift card purchased and spent as follows:
Hence, the equation in standard form is
Find the
Consider the number of $10 card purchasedis
Hence, the first combination is
Consider the number of $20 card purchased is
Hence, the second combination is
Consider any value of
Hence, the third combination is
Conclusion:
Thus, the relationship equation of gift card purchased and spent is
Thus, the three combinations of gift card purchased is given as

- Thank you.arrow_forwardThank you.arrow_forwardLet V, W, and Y be vector spaces. Suppose dim(V) dim(W) = dim(Y) = 2. = Let ("beta") be an ordered basis for V. Let ("gamma") be an ordered basis for W. Let ("zeta") be an ordered basis for Y. Suppose S is a linear transformation from V to W and that T is a linear trans- formation from W to Y. Remember that ToS is the function from V to Y defined by (TOS)(v) = T(S(v)). (a) Prove that To S is a linear transformation. (b) Prove that ° [T • S] = [T]{[S]}.arrow_forward
- Let W={(0, a, 0) | a Є R}. (a) List four elements from W. (b) Determine whether W is a subspace of R³, and prove that your answer is correct.arrow_forwardFor this problem, refer to the network as shown in Figure 1, answer the following questions. B A C FIGURE 1. For Problem (7). Let x₁ be the number of users at website A. Let x2 be the number of users at website B. Let x3 be the number of users at website C. Assume that there are a total of 900 users at these three websites. This gives us the following system of linear equations: x1 = x2 + 1x3 x2 = x1 + x3 x3 = x2 = 900 x1 + x2 + x3 = (a) Put this system into a standard form (with all variables on the left side and with the constants on the right), and convert that system into an augmented matrix, and then... (b) Use elementary row operations to put the augmented matrix into reduced row echelon form, and then... (c) Write down the solution space for this system of equations, and then... (d) Identify which website(s) would be ranked most highly by PageRank.arrow_forward4 2 Let C = -6 -3 (a) Find det(C). (b) Use your answer for (a) to determine whether C is invertible.arrow_forward
