X=3 because you have to isolate the variable by dividing each side by factors that don’t contain the variable .
Answer:
The value of x = -1
Step-by-step explanation:
=> 3x-5=2(-x-5)
=> 3x - 5 = -2x - 10
=> 3x + 2x = -10 +5
=> 5x = -5
=> x = -5/5
=> x = -1
Answer:
h = 5t
Step-by-step explanation:
So basically, its a slope problem again. You are trying to find the equation that equals hits. So you can cross off t = 5h and t = h + 5. So now, you need to find the most reasonable answer by calculating the slope.
If you try h = t + 5,
Put in 3 - you get 8
Put in 7 - you get 12
But on the table you get 15, 36 respectively.
If you try h = 5t,
Put in 3 - you get 15
Put in 7 - you get 35
Which is much closer to the numbers in the table, therefore it is the answer.
Y = -3x + 5
the points to plot on the graph: (-1, 8) , (0, 5) , (1, 2) , (2, -1)
connect those points and the graph and that should look like y = -3x + 5 which has a slope of -3.
