Alice buys some inexpensive bracelets and necklaces as party favors for her jewelry showing. she pays $8 for each necklace (n) and $7 for each bracelet (b). she spends less than $120. which inequality models this situation?
a) 7b + 8n ≤ 120
b) 7b + 8n > 120
c) 7b + 8n ≥ 120
d) 7b + 8n < 120

D.

Step-by-step explanation:

Given : Alice buys some inexpensive bracelets and necklaces as party favors for her jewelry showing.

She pays $8 for each necklace (N) and $7 for each bracelet (B).

Then , the cost of N necklaces = $8N

Cost of B bracelets = $7B

Total money spent =  Cost of N necklaces+ Cost of B bracelets

=$(8N+7B)

She spends less than $120.

i.e. $(8N+7B) < $120

Hence, the inequality models this situation :

1.677

step-by-step explanation:

i'm not good at explaining stuff but if you need an answer i'm here for you.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
