Answer:
Step 3
Step-by-step explanation:
She made her first mistake in Step 3.
This is because 4/7 is actually less than 5/3.
Step 1 and 2 are mathematically accurate.
1/2 is less than 1.
So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.
Therefore, Step 3 contains the mistake.
Accuracy is how close a measured value is to the actual (true) value.
Answer:
f(1) = 8
Step-by-step explanation:
Step 1: Define
f(x) = 7(x - 1) + 8
f(1) = x = 1
Step 2: Substitute and evaluate
f(1) = 7(1 - 1) + 8
f(1) = 7(0) + 8
f(1) = 8
Answer:
29.16
Step-by-step explanation:
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,

Now, subtract 2 from the above expression,

Hence, the required expression is x²-2.
