Answer:
Step-by-step explanation:
Let the number of weeks be x
<u>Then Kendal's CD's</u>
<u>Raymond's CD's</u>
<u>Time when they have equal CD's</u>
- 39 + x = 15 + 3x
- 3x - x = 39 - 15
- 2x = 14
- x = 7 weeks
Answer:
a.
b.
Step-by-step explanation:
a. The equation of a polynomial can be written using its graph by finding the x-intercepts.
The graph has x-intercepts -4, 0, and 3. The x-intercepts are the solutions from the factors of the equation. -4 resulted from x+4. 0 resulted from x except at 0 it doesn't cross through. It touches meaning it has an even exponent likely . And 3 resulted from x-3. Putting these factors together is the equation in factored form.
b. If the function is shifted 2 units to the left then the x-intercepts become -6, -2, and 1. So the factors are .
Answer:
4 questions
Step-by-step explanation:
90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:
0.9x = 36
x = 40
She must have gotten 40 - 36, or 4 questions wrong.
