Step-by-step explanation:
<span>What is the value of mc023-1.jpg?
73
90
290
365
answer is 90</span>
Add three to both sides
2x greater than 14 - 5x
Add 5x to both sides
7x greater than 14
divide both sides by 7
x is greater than 2
Answer:
infinite solutions
Step-by-step explanation:
replace x with 3y + 9 in the second equation
9 - (3y + 9) = -3y ➡ 9 -3y -9 = -3y ➡9-9 = 3y-3y ➡ 0 = 0
this means whatever numver you write instead of y there will be a solution.
Answer:
(1, -1)
Step-by-step explanation:
If you replace y and x with (1 and -1) you have -1 - 2^1 < -3
And that equals -3 if solved. The sign says equal to or less than, so you answer is (1, -1)
