Answer:
Step-by-step explanation:
Since the phone costs $7 for 3 minutes i.e $7=3minutes
$x = 1 minute
$7 = 3x
x = 7÷3
x = $2.33
Answer:
-x
The slope-intercept equation is y = -x + 1
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
square: 10² = 100
Circle: π*5² = 3.14*25 = 78.5
In the squqre not in the circle: 100-78.5 = 21.5
Answer:
Step-by-step explanation:
Create a linear equation for line AB and line CD
Find slope using slope formula
then use point-slope form of linear equation
(where m is the slope and and are two points on the line)
<u>Line AB</u>
<u>Line CD</u>
To find the point of intersection, equate the equations and solve for x::
AB = CD
Substitute found value of x into one of the equations and solve for y:
Therefore, point of intersection is
Answer:
the answer is below
Step-by-step explanation:
We must find the equation in order to make the graph.
According to the statement, the equation would be:
E = v * t - Ei
Being Ei (20) the initial elevation, t the elapsed time and the speed that is 4, we replace and we are left with:
E = 4 * t - 20
Now, we must calculate the corresponding values:
E (0) = 4 * 0 - 20 = -20
E (1) = 4 * 1 - 20 = -16
E (2) = 4 * 2 - 20 = -12
E (3) = 4 * 3 - 20 = -8
E (4) = 4 * 4 - 20 = -4
E (5) = 4 * 5 - 20 = 0
If we graph we would have the attached image:
