Answer:
5 units
Step-by-step explanation:
Notice that the x-coordinate is the same for both points, but that the y-coordinates differ by five units. The distance between these two points is therefore 5 units.
Answer:
<u>16 ounces</u> of the 30% hydrochloric acid solution is used in order to obtain the 25% solution.
Step-by-step explanation:
Let amount of 30% ounces be 'x' and that of 15% ounces by 'y'.
Given:
Total amount on mixing both the solution = 24 oz
∴ ![x+y=24\\x=24-y------------ 1](https://tex.z-dn.net/?f=x%2By%3D24%5C%5Cx%3D24-y------------%201)
Also, the total acid content in the resulting 25% solution is equal to the sum of the acid contents in 30% and 15% solutions.
∴ ![0.30x+0.15y=0.25(24)\\0.30x+0.15y=6-------2](https://tex.z-dn.net/?f=0.30x%2B0.15y%3D0.25%2824%29%5C%5C0.30x%2B0.15y%3D6-------2)
Now, plug in 'x' from equation (1) into equation (2). This gives,
![0.30(24-y)+0.15y=6](https://tex.z-dn.net/?f=0.30%2824-y%29%2B0.15y%3D6)
![7.2-0.3y+0.15y=6](https://tex.z-dn.net/?f=7.2-0.3y%2B0.15y%3D6)
![-0.3y-0.15y=6-7.2](https://tex.z-dn.net/?f=-0.3y-0.15y%3D6-7.2)
![-0.15y=-1.2](https://tex.z-dn.net/?f=-0.15y%3D-1.2)
ounces
Therefore,
ounces
Hence, 16 ounces of the 30% hydrochloric acid solution is used in order to obtain the 25% solution
Answer:
y=2x+6
Step-by-step explanation:
slope intercept formula → y=mx+b
![\frac{6-2}{0-(-2)} =\frac{4}{2} =2\\](https://tex.z-dn.net/?f=%5Cfrac%7B6-2%7D%7B0-%28-2%29%7D%20%3D%5Cfrac%7B4%7D%7B2%7D%20%3D2%5C%5C)
so 2 is your slope and the point (0,6) crosses the y-intercept at 6 since x = 0
plugin 2 for m (or the slope) and 6 for b (y-intercept)
your answer → y=2x+6
Answer:
Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : (9*3)*6-(6*(9*3))=0 STEP 1 : Equations which are always true 1.1 Solve 0 = 0. This equation is a tautology (Something which is always true) Equation is alway true
