Answer: Justin should have multiplied 3.8 and 7.9 first.
Step-by-step explanation:
The equation that was given with regards to the question is 12.5 + 7.9x and we are told that the value of x = 3.8
The error made by Justin was that he didn't multiply 3.8 and 7.9 at first. Solving the equation will be:
= 12.5 + 7.9x = 12.5 + 7.9(3.8)
= 12.5 + 30.02
= 42.52
Answer:
Your answer would be A. f(-2) = -10.
Step-by-step explanation:
f(-2) = 3(-2) - 4
f(-2) = -6 - 4
f(-2) = -10
Hope this is helpful.
The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28. Instead modifications should have been made before applying the equation.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
Total Questions = 20
Total Points = 28
Correct Answers = +2 points
Incorrect Answers = -1 point
The viewer represents the correct answers with x and the incorrect ones with y.
x+y = 20
for every correct answers 2 points;
and for every incorrect answers, -1 point
This can be written as
2x-y = 28
The viewer's mistake is that; instead of subtracting total incorrect points from the correct points, the viewer added them together;
now
2x-y = 28
x+y = 20
On adding the equations
]3x = 48
x = 16
y = 4
This means that the contestant answered 16 questions correctly and 4 questions incorrectly
The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28.
