If you would like to solve the equation -5x - 25 = 78, you should do this using the following steps:
<span>-5x - 25 = 78
</span>-5x - 25 + 25 = 78 + 25
-5x + 0 = 103
-5x = 103 /(-5)
x = 103 / (-5)
x = - 103/5 = - 20.6
The error was already made at step 1.
Range: the set of all y-values of a graph or equation.
Y-intercept: the y-value where the graph intersects the y-axis.
Domain: the set of all x-values of a graph or equation.
X-intercept: the x-values where the graph intersects the x-axis.
Hope this helps! :)
Answer:
Find the graph that has (2,0)
Step-by-step explanation:
+ x +x
3x - 2 = 4
+ 2 + 2
3x = 6

Answer:
The angle of A is 80°
Step-by-step explanation:
Given that angle A lies on a straight line which is 180°. So in order to find A, you have to substract 100° from 180° :
∠A + 100° = 180°
∠A = 180° - 100°
∠A = 80°
