Which input value produces the same output value for the

Mathematics
1 answer:
Brrunno [24]4 years ago
4 0

Answer:

The input value that produces the same output value for the  two functions on the graph is x = -2

It's important to know some concepts:

 1. INPUT: Also called the domain of the function, it Is the set of all x-values for which the function is defined.

 2. OUTPUT: Also called the range of the function, it is the set of all y-values for which the function is defined.

So we need to know which of the following inputs produces the same output value for the  two functions on the graph

x=-3

x=-2

x=-1

x=3

By looking at the graph we can realize that the input value that produces the same output value for the two functions on the graph is the point of intersection of these graph, that is:

the point at x=-2

And the output value is the y-value:

y=1

Luke saves 10p coins and 20p coins he has 3 times as many 10p coins as 20p coins a total of 17 pounds how 10p coins does he have
Lena [83]

Answer:

10p coins does he have 102

Step-by-step explanation:

given data

saves=  10p coins and 20p coins

total = 17 pounds

to find out

how 10p coins does he have

solution

we consider here no of  20p coin = x

so equation will be here

3 ×  10 x  +20 x = 1700

30 x + 20 x = 1700

x = 34

so that

10p coins    = 3 time × 34  = 102    

20p coins    =  34

so that 10p coins does he have 102

what is the ratio for the volumes of two similar spheres given that the ratio of their radii is 4:7 A.)343:64 B.)49:16 C.)16:49
quester [9]

Answer:

Volume of the similar sphere be 64 :343 .

Option (D) is correct.

Step-by-step explanation:

Formula

Volume\ of\ a sphere = \frac{4}{3}\pi r^{3}

As given

The volumes of two similar spheres given that the ratio of their radii is 4:7 .

Let us assume that the x be the scalar multiple of the radi .

Radius of first sphere = 4x

Radius of second sphere = 7x

Putting the values in the formula

Volume\ of\ first\ sphere = \frac{4}{3}\pi\times 4x\times 4x\times 4x

Volume\ of\ first\ sphere = \frac{4}{3}\pi\times 64x^{3}

Volume\ of\ second\ sphere = \frac{4}{3}\pi\times 7x\times 7x\times 7x

Volume\ of\ second\ sphere = \frac{4}{3}\pi\times 343x^{3}

Thus

\frac{Volume\ of\ first\ sphere}{Volume\ of\ second\ sphere} = \frac{\frac{4\pi\times 64x^{3}}{3}}{\frac{4\pi\times 343x^{3}}{3}}

\frac{Volume\ of\ first\ sphere}{Volume\ of\ second\ sphere} = \frac{64}{343}

Therefore the ratio of the volume of the similar sphere be 64 :343 .

Option (D) is correct .

Maggie tells you she is deciding between two jobs for which the pay is calculated by the functions A(x) = 5x+20 B(x) = 20x+5 Exp
salantis [7]

Answer:

B(x) is the better option

Step-by-step explanation:

Let's say that these functions represent the pay f(x) in hours, x. Function B would increase linearly on a greater scale because each X is being multiplied by 20.

You'll notice this trend for larger numbers, such as 10.

A(x) = 5(10) + 20 = 70

B(x) = 20(10) + 5 = 205

Therefore, your answer is B.
