Answer:
C.
Step-by-step explanation:
All linear equations reflect that the line graph is the straight line.
The linear equation reflecting a straight line has the formula as following:
According to the table, the line graph cross four points: A (-3; -1); B(0;0); C(3;1); D(6;2), which means that the x, y of each point would fit the equation.
So that, we replace the x, y of each point in the equation and have:
1) -1 = a*-3 +b
2) 0 = b
3) 1 = a*3 + b
4) 2 = a*6 + b
From these 4 equations, it can be calculated that: a = 1/3; b = 0
So that the linear equation corresponds to the line graph is:
Answer:
8 inches.
Step-by-step explanation:
In the first bounce, the height that the ball reaches was 125 inches.
If the ball always bounces back to of the height, then after 2nd bounce it will reach
inches height.
Again, after 3rd bounce, it will reach inches height.
And, after 4th bounce, it will reach inches height. (Answer)
Answer:
The equation to determine the length is .
The Length of the exercise mat is 16 feet.
Step-by-step explanation:
Given:
Perimeter of Rectangular mat =
Let the length of the mat be denoted by 'l'
And width be denoted by 'w'.
Also Given:
The length of the mat is twice the width of the mat.
So we can say that;
⇒ equation 1
Now we know that;
Perimeter of Rectangle is equal to twice the sum of length and width.
framing in equation form we get;
⇒ equation 2
Now Substituting equation 1 in equation 2 we get;
Applying Distributive property we get;
Hence, The equation to determine the length is .
On Solving the above equation we get;
Dividing both side by 6 we get;
Now Substituting the value of 'w' in equation 1 we get;
Hence The Length of the exercise mat is 16 feet.
