Answer:
(a) no solution
Step-by-step explanation:
Writing the second equation in slope-intercept form, it becomes ...
3x -y = 2 . . . . given
y = 3x -2 . . . . add y-2 to both sides
The first equation is already in slope-intercept form:
y = 3x +3 . . . . first equation
The coefficients of x in the two equations are both 3, so the lines they describe are parallel. They do not intersect, so there is <em>no solution</em>.
Step-by-step explanation: The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.
Answer:
Option A and Option C
Step-by-step explanation:
The surface area of a cone can be calculated with this formula:
(This matches with the option A)
Where 
is the lateral area of the cone (Being "s" the slant height) and 
is the area of the base of the cone (which is a circle).
You know that BA the is the area of the base and LA the lateral area of the cone.
Then, substituting into the formula for calculate the surface area of a cone, you get:
This matches with the option C
Simplify the left side
4c+9=37
Move all terms NOT containing C to the right side of the equation
4c=28
Divide each term by 4 and simplify
28 divided by 4
Answer
C=7
