A straight line is 180°, so you add these two angles together because they make a straight line:
3x° + 75° = 180°
To find "x", isolate/get the variable "x" by itself in the equation. Subtract 75° on both sides
3x° + 75° - 75° = 180° - 75°
3x° = 105° Divide 3 on both sides to get "x" by itself
x = 35°
PROOF
3x° + 75° = 180° Substitute/plug in 35 into "x" since x = 35°
3(35)° + 75° = 180°
105° + 75° = 180°
180° = 180°

There is an error in the equation provided. Looking at other similar question such as this, I think the equation related to x and y should be 90x + 1600 = y
Answer:
a) 90
b) 1600
Step-by-step explanation:
The equation 90x + 1600 = y is an equation of a straight line in the form y = mc + c
Adjusting the equation to the general form we get
y = 90x + 1600
m = 90
c = 1600
a) the change in Mary's total pay for each copy she sells in this case is referring to the change of y to the change of x.
In other word, it is the slope of the function.
m = 90
b) if Mary didn't sell any copies, the value of x will be 0.
In graph of a straight line, the value when x= 0 is at the value of y-intercept,
c = 1600
