I’m sorry bc I don’t know how to solve all of them but
#5 is C
#3, the equation is y=4
#4, the equation is x=-6
Answer:
(a) 
(b) Here the intercept means that we pay 
more than 
for each text message received
(c) 145 text messages sent and 30 messages received
75 text messages sent and 50 messages received
180 text messages sent and 20 messages received
Step-by-step explanation:
Here we have
X×0.02 + Y×0.07 = 5
Therefore the equation is
b. Here the intercept means that we pay more than for each text message received
c. Other combinations are
145 text messages sent and 30 messages received
75 text messages sent and 50 messages received
180 text messages sent and 20 messages received.
Answer:
The equation of the line would be y = -1/2x - 15
Step-by-step explanation:
To find the equation, we need to start by looking at the original equation's slope, which is 2. Perpendicular lines have opposite and reciprocal slopes, so the new line will have a slope of -1/2.
Now we use that and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 10 = -1/2(x + 50)
y - 10 = -1/2x - 25
y = -1/2x - 15
625/1000= 0.625
100/625= 0.16
5/8= 0.625
125/200= 0.625
20/125= 0.16
365 days in a year
21 900 hours in a year * 60
1 314 000 minutes a year * 60
3 600 000 / 1 314 000 = 2.73972602739726
