Answer:
9
Step-by-step explanation:
x didn't change in value, y changed by 9
the distance between the two points is 9
Answer:
a) -3 gallons per hour
b) y = -3x +14
Step-by-step explanation:
Rate of change is computed by dividing the amount of change by the interval over which it occurred.
<h3>a)</h3>
Here the amount of gas decreased from 14 to 2 gallons, so a decrease of 14-2 = 12 gallons. That occurred over a 4-hour period, so the rate of change is (-12 gallons)/(4 hours) = -3 gallons/hour.
__
<h3>b)</h3>
The initial amount was 14 gallons, so the equation for the line describing remaining gas will be ...
y = -3x +14 . . . . gas in the tank after x hours
by Quadratic formula , 
, values of x are 
. None of mentioned options are correct according to question!
<u>Step-by-step explanation:</u>
Here we have , expression x2 + 20 = 2x or , .
We know that Quadratic formula is :
⇒ 
Putting this value in equation :
⇒
⇒ 
⇒ 
⇒ 
⇒
Therefore , by Quadratic formula , , values of x are . None of mentioned options are correct according to question!
This can be written as:
9-x>10
-x>1 (subtract 9 from both sides)
x<-1 (divide both sides by -1 and change the inequality sign)

If Jayden needs 900, and he already has 375, first you need to find out how much more money he needs. Do that first.
2. His job pays him 155 a week, so 155w. If he needs to make at least 900, that means that it would be ok if he earned equal to 900, or more. So the amount he earns is greater than or equal to 900.
3. Solve for w. This should give you your answer.
I hope this helps!
