Anwser: The hotels charge for a call is the same for a 20 minute call.
Step-by-step explanation:
Alrighty, same deal as the last problem, set up a equality, it should look like this:
$1+.80x=$2+.75x
Move the variable to the left of the equation:
.80x-.75x=2-1
Simplify
.05x=1
x=20
Answer:
Yes, Sally has enough money to buy 28 cans of soda.
Step-by-step explanation:
Yes, because £10 = 1000p
1000p / 28p = 35 cans
35 cans < 28 cans
So Sally has enough money for 28 cans.
Answer:
y = -6x + 2
Step-by-step explanation:
Slope intercept form: y = mx + b
m is the slope
b is the y-intercept
The line pictured goes down 6 for each 1 it moves to the right, slope is rise over run, in this case, -6/1 or just -6
The y-intercept is the point that the function crosses the y-axis, in this case 2
Plug those in to get:
y = -6x + 2
Answer:
It's simple.
Step-by-step explanation:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
