<span>Let one number be x and the second number y
x + y = 82
x - y = 24 
To solve by elimination add the two equations together to get
2x = 106
x = 53

If one number is 53 substitute x=53 into the first equation.
53 + y = 82
y=82-53
y=29
Check in the other equation
53-29 = 24.

Determine if the given function is a linear transformation. t(x1, x2, x3) = (−2x2, 6x3)
Zepler [3.9K]
T:\mathbb R^3\to\mathbb R^2 will be linear if for any \mathbf x,\mathbf y\in\mathbb R^3 and constants a,b\in\mathbb R, we have

T(a\mathbf x+b\mathbf y)=aT(\mathbf x)+bT(\mathbf y)

Let \mathbf x=(x_1,x_2,x_3) and \mathbf y=(y_1,y_2,y_3), and let a,b be any two scalars. Then

a\mathbf x+b\mathbf y=(ax_1+by_1,ax_2+by_2,ax_3+by_3)

By definition of T, we have

T(a\mathbf x+b\mathbf y)=(-2ax_2-2by_2,6ax_3+6by_3)
T(a\mathbf x+b\mathbf y)=(-2ax_2,6ax_3)+(-2by_2,6by_3)
T(a\mathbf x+b\mathbf y)=a(-2x_2,6x_3)+b(-2y_2,6y_3)
T(a\mathbf x+b\mathbf y)=aT(\mathbf x)+bT(\mathbf y)

Therefore T is a linear transformation.

How do you do Slope?
Lerok [7]

Answer: All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Nina works at an hourly rate of $12.25 per hour and worked 46 hours last week. She earns overtime for hours exceeding 40 hours.
Alenkinab [10]

Answer:

$600.25

Step-by-step explanation:

12.25 per week

46hrs last week

40+ = overtime

Overtime = t*1.5

------------------------------

46-40= 6hrs of overtime

40*12.25= 490 - this is her money for working 40hrs.

To figure out the money amount of overtime pay--- 12.25*1.5= 18.375 (18.38)

<em>18.38*6= 110.25</em>

add now

<em>110.25+490= $600.25</em>


=) ~i hope i helped~ =)
