Answer:
y = 75x - 747
Step-by-step explanation:
formula is y = mx + b
m is slope
slope = change in y / change in x = (-597 - -672) / (2 - 1) = 75 / 1 = 75
m = 75
Now, to find b, substitute any value from the table. Let's do (1, -672)
y = 75x + b
-672 = 75(1) + b
-747 = b
So equation is y = 75x - 747
Answer:
x = -1 and x = 1
Step-by-step explanation:
<em>Excluded values</em> are values that will make the denominator of a fraction equal to 0.
The fraction is (x+1)/(x² - 1)
x² - 1 = 0
x² = 1
x = ±1
The excluded values are x = -1 and x = 1.
In the middle there are 13 units away.
To find the x-intercept, we can put 0 into y, as any x-intercept would have a y-coordinate at 0.
y=0
y = −12x + 3
0 = -12x + 3
12x = 3
x = 3/12
x = 0.25 or 1/4
Therefore, the x-intercept=0.25 or 1/4.
Hope it helps!
The coordinates of x are (1.6, 1.2).
Solution:
Given points of the line segment are A(0, 0) and B(4, 3)
X be the point divided the line segment AB in the distance .
i.e., in the ratio of 2 : 3.
Section formula:
Here, and m = 2, n = 3
Substitute these in the section formula,
<em>X(x, y)</em> = (1.6, 1.2)
The coordinates of x are (1.6, 1.2).
