Answer:
Would be paid $69.75
Step-by-step explanation:
Since he is paid $0.75 per quart, and he has picked up 93 quarts, you would multiply 0.75 by 93. Which would give you $69.75.
Answer:
The corresponding element in the range when 5 is an element in the domain is 
Step-by-step explanation:
Given that the 5 is an element in the domain of f(x)
The function f is defined by 
To find the corresponding element in the range:
That is put x=5 in the given function f(x)
Therfore f(x) becomes
Therefore corresponding element in the range when 5 is an element in the domain is
Answer: (2, -5) (light blue answer choice)
Solving by substitution
−7x+y=−19;−2x+3y=−19
−7x+y+7x=−19+7x (Add 7x to both sides)
y=7x−19
Step: Substitute7x−19 for y in −2x+3y=−19:
−2x+3y=−19
−2x+3(7x−19)=−19
19x−57=−19 (Simplify both sides of the equation)
19x−57+57=−19+57 (Add 57 to both sides)
19x=38
19x/19 = 38/19 (Divide both sides by 19)
x=2
Step: Substitute 2 for x in y=7x−19:
y=7x−19
y=(7)(2)−19
y= −5 (Simplify both sides of the equation)
Therefore: x = 2 and y = −5
