Let x <u>represent</u> the <u>number of row</u> and y represent the <u>number of seat</u>. Then Sarah was sitting in a seat with <u>coordinates</u> (x,y).

The other ticket holder kindly told Sarah she needed to go 5 rows down and 3 seats to the right. The translation that describes Sarah movement is

  1. (x,y)→(x,y-5) - she has to find correct row that is 5 rows down from that she was actually sitting;
  2. (x,y-5)→(x+3,y-5) - in a correct row she has to move 3 seats to the right from that she sat at start.

Answer: correct choice is D

The slope of the line whose equation is x-3y= 1 is<br> 0-3<br> -1/3<br> 0<br> 0<br> 1/3
insens350 [35]

x-3y= 1

The equation needs to be rewritten in proper Slope intercept form ( y = mx+b) where m is the slope and b is the y-intercept.

x-3y = 1

Subtract x from each side:

-3y = 1-x

Divide both sides by -3:

y = 1/-3 - x/-3

Simplify:

y = 1/3x - 1/3

The slope is 1/3

STEP
1
:
Pulling out like terms

Pull out like factors :

32 - 2x = -2 • (x - 16)

STEP
2
:

Equations which are never true:

2.1 Solve : -2 = 0

This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:

2.2 Solve : x-16 = 0

Add 16 to both sides of the equation :
x = 16

Based on experimental data, the function T(x) = -3(x − 4)^3 + 10 models the temperature of a special substance after being place
Ainat [17]

I can't say for sure this answer is 100% correct because I think more info is needed.

If your teacher is looking for the turning point, then that would be (4,10)

The equation y = a(x-h)^3 + k has a turning point at (h,k). The parent function y = x^3 gets shifted h units to the right (assuming h is positive) and k units up (if k is positive). In this case, (h,k) = (4,10) so we have y = a(x-4)^3 + 10. The original turning point (0,0) has been shifted to the new turning point (4,10) which is 4 units to the right and 10 units up. The value of 'a' does not effect the turning point.

If x was say the time in minutes and y was the temperature, then the turning point of y = -3(x-4)^3 + 10 could mean that at time 4 minutes (x = 4) the substance turns from liquid to solid (y = 10 degrees).

Note: more information is needed about this function be 100% certain about the claim made.
