Answer:
x=17
Step-by-step explanation:
The angle seen here is 180 degree so the equation we make to solve for the variable should equal to 180
First let's set up our equation:
7x+2x+27=180
Then we will combine like terms:
9x+27=180
Next we have to get rid of 27 so we only have 9x on one side. To do this let's subtract 27 on both sides of the equation:
9x=153
Now all we have to do is divide both sides by 9 to isolate the variable:
and you get x=17
Your problem did not have an operator between the x and 1 so I did it as subtraction and addition. There was no answer choice -3 so D x=-9 is the answer
(2+4)/(-2-d) = -2
6 = -2(-2-d)
6 = 4 + 2d
2 = 2d
1 = d
Answer:
y = 7x + 12
Step-by-step explanation:
Slope (m) = 7
Line is passing through the point (0, 12)
y-intercept (b) = 12
Equation of line in slope-intercept form is given as:

Letter D
1-sin^2(x) = cos^2(x)
= sin^2(x)/cos^2(x)
= tan^2(x)
