Answer:

Okay to start with we know this side isn't congruent to our side with 55 degrees looking at this side we can see that x is not 95 degrees because it is an acute angle so A is crossed out. Next this side isn't congruent like I said so B is crossed out. C is possible but the angle wouldn't be as wide as it is if we had 59 degrees so C is incorrect. Leaving us with D 70 degrees hope this helps and sorry if I got it wrong!

The first one is reflection because reflection means multiplying the function by a negative constant k the K in this question is representing the -1

Find the determinancof the matrix Q.
stepan [7]

Using a Laplace expansion along the first column, we have

\det Q=2\det\begin{bmatrix}2&1\\-1&6\end{bmatrix}+3\det\begin{bmatrix}3&4\\-1&6\end{bmatrix}+5\det\begin{bmatrix}3&4\\2&1\end{bmatrix}

The determinant of a 2x2 matrix is trivial,

\det\begin{bmatrix}a&b\\c&d\end{bmatrix}=ad-bc

So we have

\det Q=2\cdot13+3\cdot22+5\cdot(-5)=67

ANEK [815]

Answer:

7 Bagels and 3 Large Coffee

Step-by-step explanation:

Represent Large Coffee with L and Bagel with B.

We have that:

0.99B + 1.29L = 10.80 ---- Amount spent

and

B = L + 4 ---- Quantity

Required

Determine the value of L and B

Substitute L + 4 for B in the first equation

0.99B + 1.29L = 10.80

0.99(4 + L) + 1.29L =  10.80

Open Bracket

3.96 + 0.99L + 1.29L =  10.80

3.96 + 2.28L =  10.80

Collect Like Terms

2.28L =  10.80 - 3.96

2.28L =  6.84

Solve for L

L =  6.84/2.28

L =  3

Recall that

B = 4 + L

B = 4 + 3

B = 7
