HELp ASAP!!!! Natalie works in a toy shop and earns $43 per day. She earns an extra $3 for each toy she sells. If Natalie wants

to earn at least $70 per day, which inequality shows the minimum number of toys, n, that she should sell? (5 points)
a
43 + 3n ≥ 70, so n ≥ 9

b
43 + 3n ≤ 70, so n ≤ 9

c
43 + 3n ≥ 70, so n ≥ 24

d
43 + 3n ≤ 70, so n ≤ 24

Help meh plz I just need answer question in pic
Yanka [14]

Answer:

A

Step-by-step explanation:

At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1)  part. This happens for x=1. So you can already rule out answers C and D.

Now fill in x=-2 in both remaining answers and see what happens.

For A: y = -2(-2 - 1)² + 3 = -15

For B: y = (-2 - 1)² + 3 = 12

That eliminates B and leaves A.

Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a functio
KiRa [710]

Domain: \{3.3,-1.7,-4.7\}

Range: \{5.3,3.3,-2.7\}

The relation is not a function.

Explanation:

The coordinates (3.3,5.3), (-1.7,5.3), (-4.7,3.3), (-4.7,-2.7) are plotted in the graph. The image of the graph is attached below.

The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are \{3.3,-1.7,-4.7\}

The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are \{5.3,3.3,-2.7\}

The relation (3.3,5.3), (-1.7,5.3), (-4.7,3.3), (-4.7,-2.7) is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.
