The 4-liter acid material was a lower concentration than 40%. Call it 4 liters of x percent acid.
4x+10*40
————— =30
X+10
Answer:
Step-by-step explanation:
add like terms.
simplified it would be 2ab+2xy or 2(ab+xy)
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Answer:
Step-by-step explanation:
(-3.1 - 4.92)/2 = -8.02/2 = -4.01
(-2.8 - 3.3)/2 = -6.1/2= -3.05
(-4.01. -3.05) the midpoint
Answer:

Step-by-step explanation:
The scatter plot shows that there is a negative linear trend. That as the distance to the coffee shop increases, whatever the y value represents goes down.
6 below and 6 above
(1,4) (7,1) Coordinates of the two points on the trend line
I can't see what the Y axis represents so can't really explain the prediction but as the distance to the coffee shop increases, whatever the Y axis represents will decrease.
