The vertex form of the function gives the vertex as (-6,48). The vertex of f(x)=x^2 is (0,0) so from this information, the vertex is moved LEFT 6 and UP 48. This cancels out two options. The coefficient -3 tells us that the graph is flipped or reflected over the x-axis (negative sign flips graph) and that all y-values will be 3 times as large. Larger y-values for the same x inputs makes the graph narrower.
Answer:
You can expect at least 9 of her postcards to arrive within a week
To find that, we multiply the number of postcards by the probability
15 x 0.62 = 9.3
Hope this helps
Good Luck
Answer:
5
Step-by-step explanation:
The leading coefficient belongs to the term with the largest exponent
Given
5
- 7x³ + 2x + 1 ← in standard form
The leading term is 5
← with leading coefficient 5
First you divide $4000 by 160 to see how much each book costs. Then you multiply 2 times the cost for each book and subtract that from $4000.
$4000/160= $25
$25=1 book
So if the store gives away 2 books that's $50 dollars. $4000-$50 equals 3,950
Hello there,
To find out the equation you need to use slope intercept form...
y = mx + b
The only equation above that follows that form is...
y = 2x
Hope I helped!!
