Answer:
3
Step-by-step explanation:
Direct variation is y=kx where k is a constant
the fiest way to see if it is direct or not, is if x increases, then y increases as well,
then we see if y=kx is valid, basically if we have a constant of variation
the first one x increase and y increase
see if same constant
y=kx
-4.5=-3k
1.5=k
so
see next one
-1 and 3
-3=-1(k)
-3=-1(1.5)
-3=-1.5
false
not it
2nd is increase and y decrease, so not direct variation
3rd is x is same but y increase so nope
4th is x increase and y increase, now test the constant
-7.5=-3k
2.5=k
-1 and -2.5
-2.5=-1k
-2.5=-1(2.5)
-2.5=-2.5
true
answer is last option
Answer:
Step-by-step explanation:
<h3>#1</h3>
- 15 ⋅ 6 - 2² ⋅ 8 + 4³ =
- 15 ⋅ 6 - 4 · 8 + 64 =
- 90 - 32 + 64 =
- 58 + 64 =
- 122
<h3>#2</h3>
- 2³ + 2² ⋅ 2 + 6 - 2¹ ⋅ 2⁰ - 1 =
- 8 + 4 · 2 + 6 - 2 · 1 - 1 =
- 8 + 8 + 6 - 2 - 1 =
- 22 - 2 - 1 =
- 20 - 1 =
- 19
Answer:
40 years old
Step-by-step explanation:
John is 23. Multiply that by 2 and its 46. 46-6 is 40, which is how old Davis is. Johns age, 23, plus Davis age, 40, is 63
