Answer:

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form. That form is usually written $y=mx+b$ where m is the slope and b is the y-intercept.

Solve the first equation for y.

$6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2$

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

$y+3x=2\\y=-3x+2$

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.

The height of a square prism is 3n + 1. The volume of the prism is 3n³ + 13n² + 16n + 4. What is the area of the square base of

EastWind [94]

If s is the side of the square base, the area of the square base is s^2.
The volume of the square base is,
V = (s²) (h)
s² = V/h
s² = 3n³ + 13n² + 16n + 4 / 3n + 1
You can do this division by factoring, synthetic division, or by plain division.
Factoring out 3n + 1 from the numerator gives you:
s² = (3n + 1)(n² + 4n + 4) / 3n+1
s² = n² + 4n + 4

Therefore, the area of the square base is n² + 4n + 4.

Mathematics Areas and perimeters

sweet-ann [11.9K]

Answer:

54.5 Sq. cm

Step-by-step explanation:

area of a right angled triangle = 1/ 2 × base × height 

(here, the base is 8 and height is 6)

= 1/ 2 × 6 × 8

= 4 × 6

= 24 Sq. cm

area of a circle = $\pi$ r²

(r is the radius that is diameter/ 2, and the value of $\pi$ is 3. 14)

r = 10/ 2 = 5 cm

= 3. 14.× (5)²

= 3.14 × 25

= 78.5 Sq. cm

area of the shaded region = area of Circle - area of triangle

= 78.5 - 24

that is option 3

Find the equation of the circle that is shifted 5 units to the left and 2 units down from the circle with the equation x^2+y^2=1

marysya [2.9K]

Shifting a circle results to changes in the coordinates of the circle. For instance, if the coordinates of the center of the circle is taken to be (0,0), the new coordinates will be [(0+5),(0+2)] after shifting. The equation of the circle will also change with the same margin.

That is, the new equation will be;
(5+x)^2+(2+y)^2 =19

Notice, only the coordinates changes.
