Answer:
see explanation
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All the equations given are in slope- intercept form
y = 2x + 1 → with m = 2
y = x - 4 → with m =
y = x + 1 → with m = 1
y = - x - 3 → with m = -
y = 10 + x → y = x + 10 → with m = 1
Thus
y = x + 1 and y = 10 + x are Parallel since both have m = 1
y = 2x + 1 and y = - x - 3 are Perpendicular since 2 × -
= - 1
Answer:
Option C is correct
Step-by-step explanation:
Given: inequality is
To find: situation that can be represented by the given inequality
Solution:
Cost of Dunkin Donuts gift card with Daniel = $50
Amount spent by Daniel per day = $3.50
Cost of Dunkin Donuts gift card with David = $100
Amount spent by David per day = $6
Amount left with Daniel after x days =
Amount left with David after x days =
According to question,
Amount left with Daniel after x days > Amount left with David after x days
So, he inequality that satisfies the situation is
Option C is correct
