Answer:
x < -4
Step-by-step explanation:
Step 1: Write inequality
-4x + 5 > 21
Step 2: Solve for <em>x</em>
- <u>Subtract 5 on both sides:</u> -4x > 16
- <u>Divide both sides by -4:</u> x < -4
Answer:
C) Mapping
Step-by-step explanation:
<span>B. Square the number of the term, n</span>
Answer:
option C is correct
Step-by-step explanation:
We need to find the determinant.
= -1(7*9 - 3*9)-( -3)(4*9 - 3*3) -2(4*9 -7*3)
= -1(63-27) +3 (36 - 9) -2( 36- 21)
= -1(36)+3(27)-2(15)
= -36+81-30
= 15
Option C is correct
If tan(x) = a/4, then
a is opposite <span>to the angle x and
4 </span><span>is adjacent to the angle x
</span>If cos(x) = 4/b, then
4 is adjacent to the angle x and
b is the hypotenuse
sin(x) = opposite/hypotenuse =
a/b
Answer is D.
