Answer:

(3, 4)

Step-by-step explanation:

A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).

Such that a function can map each element of the domain into only one element of the range.

Then, if a "function" has:

f(x1) = y1

and

f(x1) = y2

It is mapping the input "x1" into two different outputs, then this is not a function.

Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)

(The first value is the input and the second one is the output)

Then the point that does not belong to the graph, is the point that has the same input and different output.

(3, 4)

Any of the other points could belong to the graph.

Which is the graph of a quadratic equation that has a negative discriminant?
vovikov84 [41]

Answer:

Here's what I get  

Step-by-step explanation:

The formula for a quadratic equation is

ax² + bx + c = 0

The quadratic formula gives the roots:

x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} =  \dfrac{-b\pm\sqrt{D}}{2a}

D is the discriminant.

It tells us the number of roots to the equation — the number of times the graph crosses the x-axis.

D = \begin{cases}\text{positive}  & \quad \text{2 real solutions}\\\text{zero} & \quad \text{1 real solution}\\\text{negative} & \quad \text{0 real solutions}\\\end{cases}

It doesn't matter if the graph opens upwards or downwards.

If D > 0, the graph crosses the x-axis at two points.

If D = 0, the graph touches the x-axis at one point.

If D < 0, the graph never reaches the x-axis.

Your graph must look like one of the two graphs on the right in the Figure below.

Problem is in the attached image. Thanks in advance!
lutik1710 [3]

Answer: it will take 2.5 hours for both people to meet after person B leaves.

Step-by-step explanation:

The distance between the house of person A and his cousin's house is 234 miles.

At the point where they meet, they would have travelled 234 miles.

Person A travelled at an average speed of 44 miles per hour.

Let t represent the time spent by Person A in travelling from his house to the point where they meet.

Distance = speed × time

Distance covered by person A would be

44 × t = 44t

One and half hours later, person B leaves his house to visit person A, travelling at an average speed of 62 miles per hour. This means that total time spent by person B in travelling to the point where they meet is (t - 0.5) hours. Distance covered would be

62(t - 0.5) = 62t - 31

Since the total distance covered is 234 miles, then

44t + 62t - 31 = 234

106t = 234 + 31 = 265

t = 265/106 = 2.5 hours

The Sugar Sweet Company is going to transport its sugar to market. It will cost $6500 to rent trucks, and it will cost an additi
inessss [21]

Answer:

$10000 Total cost to transport 14 tons

Step-by-step explanation:

The total cost C(S) = $6500 + ($250/ton)S.  <em>This is a linear function with initial value $6500 and slope $250/ton.</em>

C(14) = $6500 + ($250/ton)(14) = <em>$10000 = Total cost to transport 14 tons</em>

I need help on question 9.
KengaRu [80]

Answer: C) 40 degrees

Step-by-step explanation:

if the total angle is 70 degrees and part of it is 30 degrees

then the other part is x degrees

30 + x = 70

30 - 30 + x = 70 - 30

x= 40

Hope this helped!
