Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 <u>4x + 14y = - 24</u><u> </u> {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2
Answer:
FIRST OPTION.
THIRD OPTION.
FOURTH OPTION.
FITH OPTION.
Step-by-step explanation:
The equation of the line in slope-intercept form is:

Where m is the slope, b the y-intercept and the exponent of x is always 1 or 0.
Solve for y from the equations shown below:

(In this linear function the slope is 0)

(It is a linear function)

(It is a linear function)
Equation of the line whose slope is not defined:

Answer:
Cylinder
Step-by-step explanation:
Cones are pointed at the top or bottom
Rectangular Prisms are shaped like rectangles
The answer would be D, not sure if you still need it.
