Answer:
Step-by-step explanation:
because The curve C crosses the x-axis at the origin and at the points A and B => the x coordinates of A and B are the solution of the equation:
x(x + 4)(x - 2) = 0
<=> x = 0
x = -4
x = 2
because the x-coordinates of the points A and B aren't 0 and the x-coordinate
of A is a negative value
=> the x-coordinate of A is -4
the x-coordinate of B is 2
Answer:
<h3> The first: The easiest to solve for is x in the first equation.</h3>
Step-by-step explanation:
To get x from first equation you just need to subtract 4y from both sides.
The rest of variables needs two operations to get variable - subtracting and then dividing.
Answer:
C. y = 4x, table B, graph A
Step-by-step explanation:
Charges = $4 per hour (this is the slope, m,)
m = 4
The equation can be represented in the form of y = mx
Where,
m = slope = 4
Substitute m = 4 into y = mx
Thus:
y = 4x
✔️The table that represents the equation y = 4x showing that for 1 hour, the charges is $4 is table B (x = 1, y = 4).
Table B represents the parking cost.
✔️The equation with a slope of 4 is the equation that represents the parking cost. Thus, in graph A, when x = 1 (hour), y = 4 (cost).
Therefore, graph A is the answer.
Answer:
<h2>A'(-1, -4)</h2>
Step-by-step explanation:
A(x, y)
reflected across the x-axis: A'(x, -y)
reflected across the y-axis: A''(-x, y)
We have A(1, 4)
reflected across the x-axis: (1, -4)
and then reflected across the y-axis: A'(-1, -4)
Answer:
x = 8
Step-by-step explanation:
Since AB and BC combined would create the total amount of distance between AC your equation becomes 2x+1+3x = 41. 2x and 3x share the same variable therefore you can add them together which then makes the equation 5x+1 = 41. Now the equation can be solved, subtract 1 from both sides which gives you 5x = 40. From there you divide 5 from both sides which leaves you with 8 as the value of x.
