y=-3x+4

x=2y+6

y + 3x =4

-2 + =6

x= 2y +6

y+3.(2y+6)=4

7y = -14

7y=-14

y=-2

y=-2

x=2y+6

x=2(-2)+6=2

solution is {y,x}= {-2,2}

Help please give answer please
Vsevolod [243]

The mean is 8 gerbils and the MAD is 4.29.

<h3>What is the mean?</h3>

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

(0 + 3 + 6 + 9 + 11 + 13 + 14) / 7 = 8

What is the MAD?

MAD =  ∑ l x - m(x) l

| (0 - 8) + (3 - 8) + (6 - 8) + (9 - 8) + (11 - 8) + (13 - 8) + (14 - 8)| / 7 = 4.29

4. 7 + 14x<br> What does that mean
kotegsom [21]

7 + 14x means that a number x (x could be any real number) times 14 is added to 7.

So if x = 2:

7 + 14x = 7 + 14(2) = 28 + 7 = 35

Happy to help!

Is -2 considered a real number
lyudmila [28]

Yes. If we wanted to get even more specific, -2 is an integer, which falls under the label of the real numbers. √-2, on the other hand, is an imaginary number. The square root of -1 doesn't exist in the real numbers, so we invent a new number i with the property that i² = -1. Blending real and imaginary numbers together creates <em>complex numbers, </em>numbers with a real and imaginary part. This extension of the number system is tremendously useful because it essentially makes numbers two-dimensional, allowing us to manipulate and study them through a geometric lens.

1. A computer technician charges a flat fee of $35 to repair a computer in addition to an hourly rate of $22.50. The technician
Misha Larkins [42]

1. Multiply the hourly rate by the number of hours worked ( 22.5h) add that to the flat fee ( 22.5h +35) and that needs to be equal to or greater than what he expects to make:

A. 22.5h + 35 ≥ 215 , with a solution of h ≥ 8

2. Same method as number 1:

C. $3 + 1.80m ≤ $25

3. Each fraction would need 1 negative sign and have the same numerator and denominator, so the answer would be B.6/-7
