We have been given a table which lists some of the characteristics of the houses on Katrina’s street.

There are four different relation choices are given. now we have to identify which relationship describes a function.

We know that relations are written usually in ordered pairs (x,y) and a relation can be function only if x-value doesn't repeat.

So we just have to find which of the given ordered pair choices has no repeated x-value in the table.

We see that only "Appraised value" has no repeated value in the table. Hence 4th choice (appraised value, property tax) is the correct answer.

3x+y=7 6x+4y=22 can somebody help me solve this problem?

swat32

Hey there!

$\boxed{x=1;y=4}$

$3x + y = 7 \\ \\ 
 6x + 4y = 22$

$y = -3x + 7 \\ \\ Plug \ this \ in \ for \ variable \ (y) \ in \ equation \ \\ \\ 

 6x + 4*(-3x+7) = 22 \\ \\ 
 -6x = -6 \\ \\ 6x=6 \ x+1 \\ \\ x=1 \ y=-3x+7 \\ \\ \boxed{y=-3(1)+7=4} \\ \\ \boxed{\boxed{x=1;y=4}}$

I hope this helps you!

A rectangle has a length that is 8 less than its width, w. The perimeter is 52. Which equation can be used to determine its

Juliette [100K]

Answer:

2(w-8) +2w=52

its perimeter so u multiply everything by 2 and since u dont know the length but know its 8 less u subtract by width

The product of 3 consecutive even integers is equal to the cube of the first plus the square of the second plus twice the square

algol [13]

Answer:

6, 8 and 10 and -2, 0, 2

There are two roots x = -2 and 6,

but the since I don't believe 0 is an even number the answer is 6, 8 and 10

I was incorrect according to G0ggle zero is an even number so another answer is -2, 0, 2

Step-by-step explanation:

read the question and convert the English to mathematics

x, y and z even consecutive number

y = x+2

z = y+2 = x+4

and

xyz = x³ + y² + 2z² substitiute x terms in for y and z

x(x+2)(x+4) = x³ + (x+2)² + 2(x+4)² solve for x by graphing on DEMOS

x = -2, 6 solved algebraically below

x = -2 y=0 z=2

x = 6 y=8 z=10

Checked both answers

xyz = x³ + y² + 2z²

-2(0)2 = -8 + 0 + 8 when x = -2

0 = 0

and

6(8)(10) = 6³ + 8² +2(10)² when x = 6

480 = 216+64+200

= 480

x(x+2)(x+4) = x³ + (x+2)² + 2(x+4)² solved algebraically

(x²+2x)(x+4) = x³ + x² +4x +4 + 2x² + 16x + 32

x³ + 6x² + 8x = x³ + x² +4x +4 + 2x² + 16x + 32

x³ + 6x² + 8x = x³ + 3x² + 20x + 36

3x² - 12x - 36 = 0 factor out the 3

3[x² - 4x - 12] = 0

3(x+2)(x-6) = 0 x = -2 and -12

Bijou has $72 in her savings account and plans to save $x each month for 8 months. The expression $8x+$72 represents the total a

AfilCa [17]

Answer:

The total money in account after 8 months is $72 + $8 x

Step-by-step explanation:

Given as :

Total money available in saving account = $72

The money saves each month in account = $x

So, The money saves in account after 8 months = $x × 8 = $8 x

Let The total money in account after 8 months = $A

Or, A = money available in saving account + money saves in account after 8 months

i.e A = $72 + $8 x

So, The total money in account after 8 months = A =$72 + $8 x

Hence, The total money in account after 8 months is $72 + $8 x Answer
