Answer:
16) No
17) (c)
Step-by-step explanation:
For a lot of multiple-choice matrix problems, a simple test is all that is needed to determine the correct answer.
16) The determinant of A is (-2)(-2) -(2)(-3) = 10. So, we expect to see values in the inverse matrix that are 0.2 and 0.3. Alas, they're not there. The matrices are not inverses.
A^-1 = [[-.2, .3][-.2, -.2]]
__
17) The matrices are both 3×3, so their product is possible (eliminates choice D). The upper left term is different among the answer choices, so we can determine the correct one by computing that term only.
BA=C
c11 = (5)(1) +(7)(5) +(3)(-1) = 5 +35 -3 = 37
This matches the third choice (C).
If you use a calculator to compute the full matrix product, it matches choice C in all details.
Answer:
Step-by-step explanation:
4 1/2 - 2 5/8
4 4/8 - 2 5/8 = 1 and 7/8
i mean i guess you could also do this witho ut sol ving
4 4/8 - 21/8 --> 36/8 - 21/8
i dk it's si mplify not solve so here?
slope intercept form
y=mx+b
x-y =2
we need to subtract x from each side
x-y-x = -x +2
-y = -x+2
multiply each side by -1
-1*-y = -1(-x+2)
y = x -2
the slope intercept form is
y = x-2
