28 divided by 4= 7
7-3=4
answer: 4 notebooks left.
7.50 times hours would be her pay then add the bonus x number of bouquets
a = 7.50h +(bn)
Answer:
a) 
b) 
Dividing both sides by 0.448 we got:

We can appy the exponent
in both sides of the equation and we got:

Step-by-step explanation:
For this case we know the following function:

The notation is: x is the weight of the crab in grams, and the output f(x) is the weight of the claws in grams.
Part a
For this case we just need to replace x = 2 gram in the function and we got:

Part b
For this case we know tha value for
and we want to find the value of x who satisfy this condition:

Dividing both sides by 0.448 we got:

We can appy the exponent
in both sides of the equation and we got:

You need to substitute the number 6 into the function. The output would be 72, because when l(6) = 12(6), you would get l(6) = 72.
Answer:A vertex (or node) of a graph is one of the objects that are connected together. The connections between the vertices are called edges or links. A graph with 10 vertices (or nodes) and 11 edges (links).
Step-by-step explanation: (The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
