80 * 3.5 = 280
she travels around 280km in 3.5 hours.
Answer:
a=-16, b=11, c=23
Step-by-step explanation:
The function that represents the table is
We substitute x=-5 to find the value of a.
We evaluate to obtain:
To find the value of b, we substitute x=4,
We get:
To find c, we plug in x=8,
Answer:
x = 5 or x = -5
Step-by-step explanation:
x^2−9=16
Add 9 to both sides
x^2 = 25
√x^2 = √25
x = 5 or x = -5
Answer:
number 4 or D
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The first step is to find the slope using the provided coordinates (-2, 6) and (2, 14). We can do that using the y1 - y2 / x1 - x2, like so:
6 - 14 / -2 - 2
-8 / -4
2
The slope is two, so we immediately know the answer is either A or B.
Now, plot the two points on graphing paper and determine where the line intersects the y-axis to find the y-intercept...
My graph shows the line intersecting the y-axis at 10, therefore the correct answer is:
y = 2x + 10
