Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2/3x - 1
x = 2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(2) = 2/3(2) - 1
- Multiply: f(2) = 4/3 - 1
- Subtract: f(2) = 1/3
Answer:
Hmmmm. Mr. McGill seems a little lost.
At first, I thought he might have divided both sides by 21 (to get 2x on the left), but look what happens on the right side of the equation!
(not 3, for sure)
I think Mr. McGill needs to take the class you're in!
That expression can be written as this:
7x - 6 2/3+ 3x - 4 3/4. When you add like terms:
10x - 11 5/12.
So the answer is:
10x-11 5/12
Answer:
Step-by-step explanation:
Given
Solving (a): Multiplication sentence
Rewrite of as *
Solve
Hence, the multiplication sentence is:
Solving (b): Rectangular fraction model
In (a) above, the result is 2/5
The fraction model will be represented as thus:
- Draw a rectangle
- Partition in to 5 equal parts (5 represents the denominator)
- Shade 2 of the 5 partitions (2 represents the numerator)
<em>See attachment for model</em>
The slope-point form: y - y₁ = m(x - x₁).
The slope-intercept form: y = mx + b.
We have:
and the point (-5, 7)
therefore
