X=6.62
x+1.91=8.53
you have to subtract 1.91 from both sides of the equation to get x alone on one side of the equation. Once you do that you end up with x on one side and 6.62 on the other side, giving you the answer to x.
The answer is:
B.
rational numbers
Because if you perform subtraction in a set of rational numbers, the result you get would still be a rational number.
This does not apply to the other sets.
A vertical line that passes through (-5,0)
Answer:
w = ±![\sqrt[4]{36/5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B36%2F5%7D)
Step-by-step explanation:
-8+5w^4=28
You can regroup it:
5w^4 - 8 = 28
Add 8 to both side:
5w^4 = 28 + 8
5w^4 = 36
Divide both side by 5:
5w^4/5 = 36/5
w^4 = 36/5
Take the 4 root of both sides:
w = ±![\sqrt[4]{36/5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B36%2F5%7D)
Hope this help you :3
