The x intercept is (-10, 0)
Answer:
-9-5x
Step-by-step explanation:
they aren't the same because of the variable on 5x. You can simplify the problem to -9-5x but that's about it unless it equals something.
Answer:
The measure of the three angles are 120°, 20° and 40°
Step-by-step explanation:
Let
x ----> the measure of the first angle
y ---> the measure of the second angle (smallest angle)
z ---> the measure of the third angle
Remember that
The sum of the angles in a triangle must be equal to 180 degrees
so
----> equation A
-----> equation B
------> equation C
solve the system by substitution
substitute equation B and equation C in equation A
![(y+100)+y+(2y)=180](https://tex.z-dn.net/?f=%28y%2B100%29%2By%2B%282y%29%3D180)
solve for y
![4y+100=180](https://tex.z-dn.net/?f=4y%2B100%3D180)
![4y=180-100](https://tex.z-dn.net/?f=4y%3D180-100)
![4y=80](https://tex.z-dn.net/?f=4y%3D80)
![y=20\°](https://tex.z-dn.net/?f=y%3D20%5C%C2%B0)
<em>Find the value of x</em>
----
<em>Find the value of z</em>
----> ![z=2(20)=40\°](https://tex.z-dn.net/?f=z%3D2%2820%29%3D40%5C%C2%B0)
therefore
The measure of the three angles are 120°, 20° and 40°
X - 4y = 12 ----(1)
y = 1/4 x - 3 ----(2)
(2)*4 ; 4y= x-12
(1) is exactly the same equation with (2)
so there are many solutions (c)
I'm calculated and I figure that it's graphing
