It's always easier to understand a concept by looking at specific examples with pictures, so I suggest looking at the dilation examples below first...before you try to internalize the steps listed below and that explain the general formula for dilating a point with coordinates of (2,4) by a scale factor of <span><span>12</span><span>12</span></span>.
<span><span>1) multiply both coordinates by scale factor<span>(<span><span>2⋅<span>12</span>,4⋅<span>12</span></span><span>2⋅<span>12</span>,4⋅<span>12</span></span></span>)</span></span><span>2)
2. Simplify(1,2)</span><span>3)
3. Graph(if required)<span> </span></span></span>
Answer:
<u><em>C. strong negative</em></u>
Step-by-step explanation:
The reason why is because, the student's grade is falling dramatically while they watch TV. So therefore, we can erase A and D. B maybe however, it isn't "weak" but it is a heavy decrease. Therefore, your answer would be C.
Answer:
YES
Step-by-step explanation:
4(3b-4)=2(6b-8)
12b-16=12b-16
YES
Answer:
A
Step-by-step explanation:
Lets find the values:
<em>Gained</em><em> </em>2.2 kg = 2.2
<em>Lost</em><em> </em>1.5 kg = (-1.5)
<em>Lost</em><em> </em>3.7 kg = (-3.7)
Adding these would be represented by the equation:
2.2 + (-1.5) + (-3.7) = ?
