Answer:
3rd Matrix
Step-by-step explanation:
When you start putting the coefficients in as the matrix, you see that -9 has to be the 1st number, so that eliminates choice B and choice D as answers. You are left with choices A and C. C is the correct choice because when you plug in the second equation, your coefficient is -5, not 0.
Answer:
y = 2x+2
Step-by-step explanation:
y = mx+b
m = slope = 2
b = y-intercept = 2
Answer:
(a+b)(a-b) = a^2 - b^2
Step-by-step explanation:
Formula for volume = length × width × height
21 * 7 = 147
9 1/3 = 28/3
147 * 28 /3 = 4116/3
Simplify :
4116/3 = 1372
Volume = 1372 cm³.
