Answer:
B)
Step-by-step explanation:
Slope = -3
Y-intercept = 3
So
Equation is
y = mx+b
Where m is slope and b is y-intercept
y = -3x+3
1.5 × 10^(-4). .....this the scientific notation !
The complete question includes the graph of the parabola and is as in the attached image.
The equation of the parabola is; y = one eighthx2 + 5.
<h3>Equation of a parabola;</h3>
From observation;
- According to the graph of the parabola; we can evaluate the y-intercept of the parabola.
The y-intercept of the graph is +5; therefore value of y when x = 0 is; 5.
Additionally, the graph is concave (faces upward); the coefficient of x² is positive.
Ultimately, the required equation is; y = one eighthx2 + 5.

Answer:
y = -1
Step-by-step explanation:
As we move from point (-5, -1)
to point (2, -1), x increases by 7 and y stays the same.
The slope of this line is thus m = [-1 - (-1)] / 7, or just m = 0.
This is a horizontal line. Its equation is y = -1.
Answer:
56 mph
Step-by-step explanation:
196 miles in 210 minutes.
196 divided by 3.5 is 56.
