Answer:
(-4,-6),(-2,-5),(0,-4),(4,-2)
Step-by-step explanation:
(x,y)
x represents the x co-ordinate of a point
y represents the y co-ordinate of a point
Let Peters age be x
Phil's age is 1/5x+7---------------------------(i)
Phil's age can also be calculated as
4(1/5x+7)=2x-2--------------------------------(ii)
So,
4/5x+28=2x-2
28+2=2x-4/5x
30=10/5x-4/5x
30=6/5x
x=30*

x=25
Write the Inequality
A number b times -16 is greater than 5.
A number b is a variable... b.
Times means multiply.
-16 is what you are multiplying b by.
Is greater than means the greater than symbol.
5 is what the past statements are greater than.
So this is the inequality.
-16b > 5
Solve the Inequality
You need to isolate b.
To do this, divide each side by -16. You do this because b is being multiplied by -16. You know that any number divided by that number equals 1, canceling the number.
-16b ÷ -16 = b
5 ÷ -16 = -5/16
So you get b > -5/16
So to make the inequality true, b must be more than -5/16.
Or as an inequality...
b > -5/16
Answer:
13.6 gallons
Step-by-step explanation:
y = 2.72x
this means that 2.72 is multiplied by x
y = 2.72 * x
x = number of gallons
5 = number of gallons
5 = x
y = 2.72 * 5
y = 13.6 gallons
