3x + y = 6<br> 5x - 2y = 10
Eddi Din [679]

Answer:

x=2

y = 0

Step-by-step explanation:

3x + y = 6         -------------(i)

5x - 2y = 10      -------------(ii)

Multiply (i) by 2   ===>   6x +2y = 12

                     (ii)  ===>   <u> 5x - 2y =  10</u>

add   ============>    11x       = 22

                                              x = 22/11

                                              x = 2

Substitute x = 2 in (i)

       3*2 + y = 6

           6 + y = 6

                 y =  6 - 6

                 y = 0

Until 2014, the mass of a kilogram was defined as exactly equal to the mass of a special
emmainna [20.7K]

Step-by-step explanation:

We have,

Diameter of cylinder, d = 39.2 mm

Radius, r = 19.6 cm

Height of the cylinder, h = 39.2 mm

It is required to find the surface area of this cylinder. The formula of the surface area of cylinder is given by :

S=2\pi rh+2\pi r^2\\\\S=2\pi r(h+r)

Putting all values we get :

S=2\times\dfrac{22}{7}\times19.6\cdot(39.2+19.6)\\\\S=7244.16\ mm^2

7. Write the equation of a line which passes through the points (-3,5) and (6,23)
faust18 [17]

Answer:

answer to the equation is

y = 2x + 11

Step-by-step explanation:

y = mx + b

first find the slope of the line using the two points

slope \: m =  \frac{y2 - y1}{x2 - x1}  =  \frac{23 - 5}{6 - ( - 3)}   \\ =  \frac{18}{9}  \\ slope \: m = 2

substitute 2 for m and use one of the points for x and y and solve for b

5 = 2( - 3) + b \\ 5 =  - 6 + b \\ 5 + 6 = b \\ b = 11

Now that you found b, the y-intercept, you can substitute that into the equation for your line

y = 2x + 11
