Answer:
(- 1, - 1 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply the coordinates of the original point by the scale factor, that is
(- 3, - 3 ) → (
× - 3,
× - 3 ) → (- 1, - 1 )
Answer:
Hello :D
Step-by-step explanation:
Answer:
NO, YES, YES, NO
Step-by-step explanation:
Subsitute the number they give you and then solve. Finally, see if the equation is true.
13 - 7 = 20 This is equation is not true. (NO)
15 · 8 = 120 This equation is true. (YES)
24/12 = 2 This equation is true. (YES)
5 = 10 + 5 This equation is not true. (NO)
Answer: First option.
Step-by-step explanation:
You need to remember that to factorize the given expression
, you need to choose two numbers that when you add them you get "10" and when you multiply them you get "21".
These number are:
7 and 3
Because:

Therefore, you get that the factorization of the expression
is the following:

You can observe that this factorization matches with the first option.
Answer:
x=4,y=−2
Step-by-step explanation:
1 Solve for x in -2y+x=8
x=8+2y
2 Substitute x=8+2y into 3y+2x=2
7y+16=2
3 Solve for y in 7y+16=2
y=-2
4 Substitute y=-2 into x=8+2y
x=4
5 Therefore,
x=4
y=−2
