First, let's simplify the inequality as much as we can:

-4x + 7 > 15
-4x > 8

Divide by -4:
x < -2

Please help me with this math problem!! :) Will give BRAINLIEST!! :)

The rate of change will be positive and a point in the graph will be (1,250);
the function then would be y = 250x;
after 1 year she will owe USD 5,250;
she will have to make 33 payments.

How to form equation using slope and one point?
y - y1 = m(x - x1) is the equation of a straight line's point slope form, where m is the line's slope and (x1, y1) is the point through which the provided line passes.

Using slope-point equation, the equation for the payment can be taken as:
y-250 = [(500-250)/(2-1)]*(x-1)
y - 250 = 250*(x-1)
y = 250 + 250x - 250 = 250x;
Putting x = 12, for a year the amount paid is USD 3,000.
Amount she owes = USD (8250-3000) = USD 5,250;
Total amount to be paid (in USD) = 8250
Amount paid per month (in USD) = 250
Thus, number of payments required = 8250/250 = 33

Thus, the rate of change will be positive and a point in the graph will be (1,250); the function then would be y = 250x; after 1 year she will owe USD 5,250; she will have to make 33 payments.

Katarina [22]

Answer:

It will take 56 seconds

Step-by-step explanation:

A water hose used one -eighth of a gallon of water and every second. This means that the flow rate is

1/8 gallon per second.

If Halsey need to fill up 7 gallons sized containers, let x represent the number of seconds that it will take Halsey to fill up 7 gallons. Therefore,

1/8 gallons = 1 second

7 gallons = x seconds.

Cross multiplying,

1/ 8 × x = 7 × 1

x/8 = 7

x = 8 ×7 = 56 seconds
