Answer is C. Y intercept is 3. The slope is 2/3x.
Theres an app called photomath thats useful for these kinds of problems
65% of $19.
So, this would become 65/100 * 19.

Answer:
Step-by-step explanation:
You are multiplying the identity matrix by another matrix.
The effect of multiplying
1 0 0
0 1 0
0 0 1
by another matrix of the same dimensions is nil...nothing happens. So, the answer to this problem is the first matrix itself. Just copy it down.
Answer:
18°
Step-by-step explanation:
The law of cosines tells you ...
a² = b² + c² -2bc·cos(A)
Solve for cos(A) and fill in the numbers. Note that the value of cos(A) is very close to 1, so the angle will be fairly small. This by itself can steer you to the correct answer.
cos(A) = (b² +c² -a²)/(2bc) = (49 +100 -16)/(2·7·10) = 133/140
A = arccos(133/140) ≈ 18.2° ≈ 18°
