4*5 is 20
add 2 zeroes to the end because of the two you took out from 40 and 50
40*50=2000
Okay so i may be wrong but i think that the new coordinates would be (7,5). I’m assuming that the translation is up 2 and 4 to the right so you just follow the rules for translations. (a) being the amount of spaces you’re moving for x and (b) being the amount of spaces you’re moving for y
Translation a units to the right (x,y) ➡️ (x+a, y)
Translation a units to the left (x,y) ➡️ (x-a,y)
Translation b units up (x,y) ➡️ (x,y+b)
Translation b units down (x,y) ➡️ (x,y-b)
i’m not the smartest person ever but hopefully this helps. good luck!!
Answer:
x = 14
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply -2 to both sides of the equation:
-2 * (-1/2x) = -2 * -7
x = -2 * -7
x = 14
Note that when you multiply two negative numbers, the answer will be positive.
14 is your answer for x.

For a relationship to be linear, there must be a constant rate of change. To check this, you need to calculate the equation of the line.
A linear line will always have an equation in the following pattern:
y = mx + c where m is the slope and c is a constant.
This equation must be of first degree (highest power is x^1) to be linear.
Note:
the slope can be calculated using two points (x1,y1) and (x2,y2) as follows:
m = (y2 / y1) / (x2 - x2)
You can then use points from the table and substitute in the equation to calculate the value of c.
