If a linear system has no solution what happens when you try to solve the system by adding or subtracting

Mathematics

fgiga [73]3 years ago

In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. In order for the new equation to have only one variable, the other variable must cancel out. In other words, we must first perform operations on each equation until one term has an equal and opposite coefficient as the corresponding term in the other equation.

The slope of a line is -4 and it’s y-intercept is (0,4) what is the equation of the line that is perpendicular to the first line
Rasek [7]

Original line equation: y=-4x+4

Perpendicular lines have opposite reciprocals, so the slope of the perpendicular line would be 1/4x.

Perpendicular line equation: y=1/4x+b

Plug in the coordinates that the line passes through to solve for b. Plug -8 in for x and 2 in for y.

2=1/4(-8)+b

Multiply.

2=-2+b

Add 2 to both sides.

4=b

Equation of the perpendicular line: y=1/4x+4

Hope this helps! :)

What is the best approximation of the surface area of this right cone
Tatiana [17]
Use the formula for the surface area of a right cone:

\sf A=\pi rs+\pi r^2

Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):

\sf A=(3.14)(12)(15)+(3.14)(12)^2

Multiply and simplify exponent:

\sf A=565.2+(3.14)(144)

Multiply:

\sf A=565.2+452.16

Add, round to the nearest whole number:

\boxed{\sf A\approx 1017~cm^2}
