Answer:
y = (-3/4)x -2
or: y = -0.75x -2
Step-by-step explanation:
First, find the slope of the line that it parallel to. Using equation
slope m = (y2-y1)/(x2-x1),
slope of line that passes through points (4, 0) and (0, 3)
= (3 - 0) /( 0-4)
= -3/4
Since the lines are parallel, both of them have the same slope, which is -3/4.
The point (0, -2) is actually the point of y -intercept (c) of the new line, so we can simply use the slope-intercept form to find the equation of line.
y = mx + c
y = (-3/4)x + (-2)
y = (-3/4)x -2
Answer:
r
Step-by-step explanation:
Since r is not given, the length we can be find using the Law of Sines using is length r.
The Sine formula or the Law of Sines
q/Sine Q = r/Sine R
q=9.5
r is the unknown
9.5/Sine 18° = r/ Sine 135°
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
