Which of these tables represents a function?

you first eliminate the same base and bring down the exponents

-7 . 3

-7×3

= -21

Answer:

B. 60

Step-by-step explanation:

There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.

15%  got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds

The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds

Answer:

x = 13  and  x = -3

Step-by-step explanation:

divide each side by 2 first and get:

(x-5)² = 64

take the square root of each side next and get:

x - 5 = [tex]\sqrt{64}[/tex]

x - 5 = 8  and  x - 5 = -8

x = 13  and  x = -3

Answer:

Answer:

-1 is your answer,

Step-by-step explanation:

first of all, add all those scores

-3 + 1 + -2 + -4 + 3 = -5

and for average, there is 5 rounds, so divide by 5

hence answer is -5 / 5 - = -1

Answer:

f(x) = -|x| + 1.

Step-by-step explanation:

You get this by inverting the graph of  f(x) = |x| then moving it up 1 unit.

f(x) = -|x| + 1.

By invert I mean reflect in the x-axis.

Answer:

f(x) = -|x| + 1.

Answer:

11.45mm^2

Step-by-step explanation:

Given data

Circumference= 12mm

The expression for the circumference is

C= 2πr

12= 2*3.14*r

12= 6.28r

r= 12/6.28

r= 1.91mm

Hence the area of each small circle is

A= πr^2

A= 3.14*1.91^2

A= 3.14*3.6481

A=11.45mm^2

Step-by-step explanation:

-14 and -3 are the two factors of 42 which has as a sum of -17

What are Factors of a Number?

Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder

Given data ,

The number = 42

The number has both negative and positive factors

The factors of the number 42 are

The positive factors of 42 are 1 , 2 , 3 , 6 , 7 , 14 , 21 , 42

The negative factors of 42 are -1 , -2 , -3 , -4 , -6 , -7 , -14 , -21 , -42

Product of -14 and -3 = -14 x -3

                                   = 42

Sum of -14 and -3 = ( -14 ) + ( -3 )

                             = -17

Hence , -14 and -3 are the two factors of 42 which has as a sum of -17

answer:

it's a function

step-by-step explanation:

according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.

but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function

another way to solve-

for this, we will put the pairs into a graph then perform the line test-

as you can see each point has its own individual line, therefore, meaning it passed the vertical line test

good luck :)

Answer:

350x⁶+1360x⁵-1337x⁴-7618x³-5517x²+1620x+1836

Answer:

100 cubic in

Explanation

step 1: divide the figure into two

step 2 : find area then multiply by height of the cuboid

step 3 : add both

Answer:

The answer is 100.

Step-by-step explanation:

Volume = weight times height times length = 5 times 1 times 8 = 40

Volume = weight times height times length = 5 times 2 times 6 = 60

So now that we have the volume of each rectangular prism, we must add them together to get the full volume.

60 + 40 = 100

Answer:

66.6%

Step-by-step explanation:

Step one

given

A coat at a store is originally priced at $54.99

The store marks down the price down to $32.99

Required

the percent decrease

Step two:

the percent decrease= change in price/ old price*100

the percent decrease= 54.99-32.99/54.99*100

the percent decrease= 22/ 32.99*100

the percent decrease= 0.666*100

the percent decrease= 66.6%
