Answer:
a. p= 36/(m + 1)
b. p = 3
Step-by-step explanation:
If p varies inversely as (m + 1)
then p = k × 1/(m + 1). {Where k is the constant}
when p = 4, m = 8, that means 4 = k/(8 + 1)
4 × 9 = k and k = 36
a. Therefore the equation is p= 36/(m + 1)
b. When m = 11,
p = 36/(11 + 1)
p = 36/12
p = 3
Sales tax in Colorado is 2.85%, in Ohio is 5.50%, and in Rhode Island is 7%.
- Colorado:
- 3.50 = 100
- 3.60 = X
- 3.60 x 100 / 3.50 = X
- 360 / 3.5 = X
- 102.85 = X
- 2.85% = Sales tax
- Ohio:
- Y = 1.055X
- 10 x 1.055 = Y
- 10.55 = Y
- 10 = 100
- 10.55 = X
- 10.55 x 100 / 10 = X
- 1055 / 10 = X
- 105.5 = X
- 5.5% = Sales tax
- Rhode Island:
- 10 = 100
- 10.70 = X
- 10.70 x 100 / 10 = X
- 1070 / 100 = X
- 107 = X
- 7% = Sales tax
Therefore, sales tax in Colorado is 2.85%, in Ohio is 5.50%, and in Rhode Island is 7%.

Answer:
A, B, C, and E
Step-by-step explanation:
SSA doesn't work because this leaves room for two possible answers in some situations.
The other postulate, HL (hypotenuse-leg) works for right triangles; it's basically a short cut for SSS postulate because if the hypotenuse and leg of a right triangle are congruent to the hypotenuse and leg on another, the other side also has to be congruent.
Answer:
x = 0, y = -2
Step-by-step explanation:
-3x - 4y = 8 (1)
-4x - 3y=6 (2)
Multiply (1) by -4 and (2) by -3, we have:
12x + 16y = - 32 (3)
12x + 9y= -18 (4)
Subtract (4) from (3), we have:
(12x + 16y) - (12x + 9y) = - 32 - (-18)
<=> 7y = - 14
=> y = - 2
Replace y with - 2 in (3), we have x = 0
