Which coordinate plane represents the linear relationship 4x+5y=20

Answer:

-3, +3, 7/5

Step-by-step explanation:

(5x³-7x²)+(-45x+63)=0

X²(5x-7)-9(5x-7)=0

(X²+9)(5x-7)=0

Either x²-9=0

X²=9 so x=+3 and -3

Or 5x-7=0

5x=7 so x=1.4 (or 7/5)

Answer:

burrito price=$8

Taco Price=$6

Step-by-step explanation:

x=burrito price

y=taco price

3x+4y=48

solve for y

y= −3 /4 x+12

plug in

6x+2y=60

6x+2( −3 /4 x+12)=60

6x+2( −3 /4 x+12)=60

x=8

now plug in for x

3x+4y=48

3(8)+4y=48

y=6

y=6

x=8

burrito price=$8

Taco Price=$6

Answer:

{x,y}={4,7}

Step-by-step explanation:

3x - y = 5

x+ 4y = 32

y + 3x = 5   ,      4y + x = 32  

x = -4y + 32

3•(-4y+32) - y = 5

- 13y = -91

13y = 91  

 y = 7

x = -4y+32

 y = 7

x = -4(7)+32 = 4

so the final solution is:

⇒x = -4(7)+32 = 4

Answer:

67.5

Step-by-step explanation:

Step-by-step explanation:

The question is not properly formated, here is the correct format

The revenue function is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=274−4x, find the revenue if 12 units are sold. Round to two decimal places.

Step one

given the following expression

Revenue

[tex]R(x)=xp(x)[/tex]

Unit price

[tex]p(x)=274-4x[/tex]

Required

the revenue when 12 units were sold

let us find the unit price for 12 units

[tex]p(x)=274-4x\\\\p(x)=274-4(12)\\\\p(x)=274-48\\\\p(x)=226[/tex]

Hence the unit price is$ 226

[tex]R(x)=xp(x)\\\\R(x)=12*226\\\\R(x)=2712[/tex]

Revenue is $2712

There is a revenue of $5.04 if 12 units are sold.

Revenue is the product of the number of units and the price per unit. It is given by:

Revenue = number of units * price per unit

Revenue = x * p(x)

Given that the price per unit is:

[tex]p(x)=27(4)^{-\frac{x}{4} }\\\\For\ x=12:\\\\\\p(12)=27(4)^{-\frac{12}{4} }=\$0.42[/tex]

Therefore the revenue is:

Revenue = x * p(x) = 12 * 0.42

Revenue = $5.04

Therefore there is a revenue of $5.04 if 12 units are sold.

Answer:

The answer is 15

Step-by-step explanation:

Because for the ratio table its like a pattern it goes 1,5,10. So for this ratio table you divide 45 by 3,and 45 divided by 3 is 15. And in the pattern it goes up by five and and ten plus five is 15. and to check to see you can do 45 minus 15 which equals 30.

Answer:

x= - 143

Step-by-step explanation:

x/11 -3 = -16

transpose the 11

x= -13×11

x= - 143

Answer:

P [ X > 35 ]  =  0,983         or    P [ X > 35 ]  = 98,3 %

Step-by-step explanation:  See Annex valid region for 98,3 in red lines

P [ X > 35 ]  =  1  - P [ X ≤ 35 ]

P[ X ≤ z  ]  = ( X -  μ₀ ) / σ

P [ X ≤ 35 ] =  ( 35  -  50  ) / 7

P [ X ≤ 35 ] =  - 15 / 7

P [ X ≤ 35 ] = - 2,1428

We find for  z(score)  =  - 2,14  in z-table the value of  0,01618

P [ X ≤ 35 ] =  0,01618        or     P [ X ≤ 35 ] ≈ 1,62 %

And  

P [ X > 35 ]  = 1  - 0,01618

P [ X > 35 ]  =  0,983         or    P [ X > 35 ]  = 98,3 %
