Answer:
Option number B
Step-by-step explanation:
As per the statement:
Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
Given the equation as:
7h - 5 ( 3h -8 ) = -72
Using distributive property,
a ⋅ ( b + c ) = a ⋅ b + a ⋅ c
7h - 15h + 40 = - 72
Combine like terms;
-8h + 40 = -72
Subtract 40 from both sides we have;
-8h 8= -112
Divide both sides by -8 we have;
h = 14 hours
Therefore, the statement is true about Pieter’s solution is, It must be a positive number since it represents a number of hours.
First you add the numbers
6/2*3
Now you calculate the expression
6/2*3
The answer is 9, therefore 9 is your answer
Answer:
for two lines to be perpendicular m2 = -1/m2
using the formula y= mx+c
m1 = 0
for the lines to be perpendicular to each other(m2 = -1/0 )
Note: -1/0 is undefined
using the formula y-y1 = m(x-x1)
y -6 = -1/0(x-2)
cross multiply
0 = -1(x-2)
0 = -x+2
x =2(equation of the line)
