Answer:

Step-by-step explanation:
Hello, please consider the following.
We can read from the graph that the vertex is (1,-4) , it means that the equation is, a being a real number.

And the point (0,-1) is on the graph so we can write.

So the equation is.

Hope this helps.
Do not hesitate if you need further explanation.
Thank you
X=13/24 in decimal form it’s x=0.5416
Answer:
58 seconds.
Step-by-step explanation:
Since one minute equals 60 seconds, Carlos took 63 seconds.
Orlando ran in 63 seconds - 5 seconds, which is equal to 58 seconds.
Answer:
y = 2x + 1
Step-by-step explanation:
From the table attached,
x y Difference ![[d=(y_2-y_1)]](https://tex.z-dn.net/?f=%5Bd%3D%28y_2-y_1%29%5D)
-1 -1 -
0 1 1 - (-1) = 2
1 3 3 - 1 = 2
2 5 5 - 3 = 2
Since,there is a common difference 'd' = 2
Therefore, this table represents a linear equation.
Let the equation is,
y = mx + b
where 'm' is the slope and 'b' is the y-intercept.
Two points lying on the linear equation are (-1, -1) and (0, 1)
Slope 'm' = 
m = 
m = 2
And y-intercept 'b' = 1 unit
Therefore, equation of the line will be,
y = 2x + 1
