2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40
Answer:
2
Step-by-step explanation:
2
Answer:
3.89 and -0.39.
Step-by-step explanation:
To find the answer we need to find what is what based of ax squared plus/minus bx + c = 0. A is 2, b is -7, and C is - 3. Now using the formula -b plus minus square root of b squared minus 4 time a time c all divided by 2a.
What it is basically asking is if Y = -4, find the value of x in the equation 6x + 7y = 4x + 4y
To solve this you just need to plug in -4 for y and solve for x
6x + 7(-4) = 4x + 4(-4)
6x - 28 = 4x - 16
Now isolate x by adding 28 to both sides
6x - 28 + 28 = 4x - 16 + 28
6x = 4x + 8
and subtract 4x from both sides
6x - 4x = 4x - 4x + 8
2x = 8
divide both sides by 2
2/2x = 8/2
x = 4
x = 4, y = -2
Answer: (4, - 2)
Hope it helps :)
Bransliest would be appreciated
28 + vector b = -12
vector b = -40
vector b has magnitude 40 units in the negative y direction.
