Answer:
Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.
Using the formula above,
Substitute the value of m into the equation:
To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,
5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is .
Answer:
B) 161.5 in²
Step-by-step explanation:
We can separate the kite figure into <em>two triangles, by cutting it vertically</em>.
So, we have two triangles with the area of <em>1/2*(6+13)*8.5</em>.
Since there is <em>two</em> of them, the equation of the total area is <em>2*1/2*(6+13)*8.5</em>.
Simplify: <em>1*19*8.5</em> (2 and 1/2 cancel out).
Multiply: <em>19*8.5</em> = 161.5 in²
Answer:
Step-by-step explanation:
The given series is
The first term is
The last term is
To find the number of terms in the sequence, solve,
The sum of the first i-terms of an arithmetic sequence is:
We substitute the values to get;
You can simplify the fraction to get 2/5. If you convert this into a decimal you will get 0.4, so D is your answer.
