12-17/-5-(-2) so divison first,it will become 12+3.4-(-2) =two minuses will become a "+"
So,12+3.4+2=17,4
ANSWER: 17.4
Answer:
The third one, x+(x+1)+(x+2)=-21 because x, x+1 and x+2 are three consecutive numbers.
Answer:
y= 3x -6
Step-by-step explanation:
The equation if a line can be written in the form of y= mx +c, where m is the slope and c is the y- intercept.
Given that the slope is 3, m= 3.
Substitute m= 3 into the equation:
y= 3x +c
To find the value of c, substitute a pair of coordinates into the equation.
Given that it has an x- intercept of -2, the line passes through the point (-2, 0). This is because x- intercept is the point at which the line passes through the x- axis, and this occurs at y= 0.
When x= -2, y= 0,
0= 3(-2) -c
0= -6 -c <em>(</em><em>expand)</em>
c= -6 <em> </em><em>(</em><em>+</em><em>c </em><em>on </em><em>both </em><em>sides)</em>
Thus, the equation of the line is y= 3x -6.
