Answer:
EF = 9
GF = 2
Step-by-step explanation:
For EF, we want to find the distance between their c coordinates, since their y coordinates are the same. We want the distance between -4 and 5, which when you add their distance from 0, is 9.
For GF, they share the same x coordinate, so you're finding the distance between their y coordinates, which are 3 and 5. The distance between the two is 2, so the length of GF is 2.
C, because the opposite would be + 2 and none of the ions have that charge
<span>-4x + y = -25 y = 4x - 25
-6x - 6y = 0 </span>
-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5
y = 4(5) - 25
y = 20 - 25
y = -5
(5, -5)

Answer:
Step-by-step explanation:
We have been given that a skin care manufacture produces 85 g canister of skin balm. Any canister whose weight differs by more that 0.05 g cannot be shipped out.
To write an equation that would find the maximum weight of an acceptable canister (y) we will use an absolute value equation as the weight of an acceptable balm canister cannot be more than 85+0.05 and it cannot be less than 85-0.05.
This information can be expressed as .
Subtracting 85 from all the sides we will get,
Now using the definition of absolute value symbol we will get,
Therefore, the equation representing the maximum weight of an acceptable canister(y) is .
