Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
Answer:
all real numbers greater than or equal to 175
Step-by-step explanation:
Answer:
D) 2
Step-by-step explanation:
A Triangle two sides added together must always be greater than the other side.
It can not be 2 because the two sides of a triangle added are not greater than the other side.
Here 5 + 2 = 7 which is not greater than 7 on the other side, so 2 fails.
A and D
Put 3 in the equations and solve
There are a few answers but an example of one could be 7^10 * 7^5
