The Answer is:
(5a2-3a+8)+(-4a2-1)+(15a+11)
Answer:
y = 3x + 4
Step-by-step explanation:
slope = (y2 -y1)/(x2 - x1)
y2 = 19
y1 = 7
x2 = 5
x1 = 1
Slope = (19 - 7)/(5 - 1)
slope = 12 / 4
slope = 3
So far what you have is
y = 3x + b To solve for b, use either of the two points.
x = 1
y = 7
7 = 3(1) + b
7 = 3 + b
b = 4
The final equation is
y = 3x + 4
We should check that with the other point
x = 5 Find y
y = 3(5) + 4
y = 15 + 4
y = 19 Ans it checks.
Answer:
It's D.
Step-by-step explanation:
Convert each number to decimal format.
It is option D , if we convert as above we get
7.36799, 7.36666.., 7.363636.., 7.33333..
Hey!
In order to simplify this equation, we'll first have to multiply both sides of the equation by v. This will give us v on its own.
<em>Original Equation :</em>

<em>New Equation {Added Multiply Both Sides by V} :</em>

<em>Solution {New Equation Solved} :</em>

Now we'll switch sides to get v on the left side of the equation which is generally where we always want the variables to be located in these types of equations.
<em>Old Equation :</em>

<em>New Equation {Switched} :</em>

Now we'll divide both sides by v to get v on its own.

<em>New Equation {Added Divide Both Sides by V} :</em>

<em>Solution {New Equation Solved} :</em>

<em>So, this means that in the equation

Given:
diameter = 14 inches
radius = 14 inches / 2 = 7 inches
Circumference of a circle = 2 π r = 2 * π * 7inches = 14 inches * π
Area of a circle = π r² = π * (7in)² = π * 49in²
C = 14π and A = 49π
