Answer:
Sample Response: Start at the origin. The x-coordinate is −2½ , so move left 2½ units. −2½ is halfway between −3 and −2. The y-coordinate is −4, so move down 4 units. Plot the point.
Step-by-step explanation:
This is what I got putting this into to Desmos. Hope it helps :)
It means the same:
2x - 6 + 9 = 3x + 3 + x
2x +3 = 4x + 3
2x - 4x = 3 - 3
-2x = 0
x = 0/(-2) = 0
Answer:
x = 0
Answer:
see explanation
Step-by-step explanation:
f(x) × g(x)
= 11(123x - 40) ← distribute
= 1353x - 440
Substitute x = - 4 into the product
= (1353 × - 4) - 440
= - 5412 - 440
= - 5852
Answer:
40! Seconds
Step-by-step explanation:
Calculation for After how many seconds will the two fish tanks have the same amount of water
First step
Based on the information given let the equation be :
150-1/2x=120+1/4x
Second step
Now let solve for x which means that x will be the number of second by multiplying both side by 4
4(150-1/2x)=4(120+1/4x)
=600-2x=480+x
Third step
Let Add 2x on both side
600=480+3x
Third step
Let Subtract 480 on both side
600-480=480-480+3x
120=3x
Last step is to divide both side by 3
120/3=3x/3
40=x
Hence:
x=40 seconds
Therefore After 40 seconds the two fish tanks will have the same amount of water.
