Part A: Solve the equation 4(x + 5) = 9x + 4x − 34, and show your work. (5 points)
Vaselesa [24]

The value of x in the linear equation 4(x + 5) = 9x + 4x − 34 is 6 after applying the property.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have linear equation in one variable:

4(x + 5) = 9x + 4x − 34

4x + 20 = 9x + 4x − 34   (Distributive Property)

4x + 20 -4x + 34= 9x + 4x − 34 -4x +34    

(Subtraction Property of Equality and Addition Property of Equality)

54 = 9x

x = 6   (Division Property of Equality)

Thus, the value of x in the linear equation 4(x + 5) = 9x + 4x − 34 is 6 after applying the property.

Lets say you have 5 apples, but the you give away 3 of them.
To work how many you have left you take away.
5-3 = 2

Lets apply this with fractions now.
You have 9/7 yard, but then you give away 7/20 yard.
Now you take them away:
9/7 minus 7/20 = 131/140

Hope this helps :)

The equation of a circle is x2 + (y-10)2=16. The radius of the circle is units. The center of the circle is at .
aliina [53]

Answers:

Center = (0, 10)

Radius = 4

========================================================

Work Shown:

Rewrite the equation into

(x - 0)^2 + (y - 10)^2 = 4^2

Then note how it is in the form

(x - h)^2 + (y - k)^2 = r^2

We see that the center is (h,k) = (0,10) and the radius is r = 4.
