Answer:
50/3
Step-by-step explanation:
For x
3x-2(2+1)=4
3x-2(3)=4
3x-6=4
3x=4+6
3x=10
x=10/3
as we have to find 5x=?
5(10/3)

Step-by-step explanation:
<em>(4, -2)</em>
Step-by-step explanation:
For a reflection across the y-axis, you need to change the sign of the x to the opposite of what it was.
(x, y) to (-x, y)
If C has the coordinates of (-4, -2), to figure out the coordinates of C' after a reflection of the y-axis, we will change the sign of the x.
C' would be located at the coordinates (4, -2).
Answer:
=![\sqrt[3]{49x^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B49x%5E%7B2%7D%20%7D)
Step-by-step explanation:
We have been given the expression;
7 times x to the two thirds power which can be written mathematically as;
To express the above expression as a radical, we need to recall that;
![a^{\frac{b}{n}}=\sqrt[n]{a^{b}}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bb%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Ba%5E%7Bb%7D%7D)
Therefore;
![(7x)^{\frac{2}{3}}=\sqrt[3]{(7x)^{2} }\\\\=\sqrt[3]{49x^{2} }](https://tex.z-dn.net/?f=%287x%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D%5Csqrt%5B3%5D%7B%287x%29%5E%7B2%7D%20%7D%5C%5C%5C%5C%3D%5Csqrt%5B3%5D%7B49x%5E%7B2%7D%20%7D)
It’s an irrational number (can’t be expressed as a fraction with two integers).
