-6(4x + 1) + 7x + 9(x - 3) = 4
-6(4x) - 6(1) + 7x + 9(x) - 9(3) = 4
-24x - 6 + 7x + 9x - 27 = 4
-24x + 7x + 9x - 6 + 27 = 4
-8x + 21 = 4
- 21 - 21
-8x = -17
-8 -8
x = 2.125
Answer:
Option A.
Step-by-step explanation:
Consider the given problem is
Using the properties of radical expressions we get
![[\because \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Cfrac%7B%5Csqrt%7Ba%7D%7D%7B%5Csqrt%7Bb%7D%7D%5D)
![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)
Taking out common factors.
The simplified form of given expression is 
Therefore, the correct option is A.

Answer:
5.5
Step-by-step explanation:
y = 0.5x + 5
Use the slope-intercept form to find the slope and y-intercept.
<em>Slope: 0.5
</em>
<em>y-intercept: 5
</em>
Any line can be graphed using two points. Select two <em>x</em> values, and plug them into the equation to find the corresponding values.
To find the y intercept using the equation of the line, plug in 0 for the <em>x</em> variable and solve for y.
<em>y = 0.5(0) + 5
</em>
<em>y = 5</em>
To graph the y intercept using the equation of the line, plug in 1 for the x variable and solve for y.
<em>y = 0.5(1) + 5
</em>
<em>y = 5.5
</em>
Which means when x is 0, y intercept at 5 and when x is 1 y intercept at 5.5. Graph the line using the slope and the y-intercept, or the points.
This tells us, in practical terms, that, for every one unit that the x-variable increases (that is, moves over to the right), the y-variable increases (that is, goes up) by 50% of a unit.
