AAAAHHHH OKAY ILL TRY TO HELP!!!
So the Y intercept is where x =0 so just read that off the graph to get the coordinates (0,8). Then the slope is the same as the gradient so you do change in y/ change in x to get 2/4 = 1/2 or 0.5. Then to work out the equation you already have the gradient so substitute that in to get y = 1/2 x + c and then pick any point from the line ( eg (4,6)) and sub that in to get 6= 1/2 x 4 + c which is 6 = 2 + c so c is 4 so your overall equation is y= 1/2 x + 4 hope this helps :)

Rainbow [258]

0.0\overline{3}=\dfrac{1}{30}\\0.\overline{03}=\dfrac{1}{33}\\\\\dfrac{0.0\overline{3}}{0.\overline{03}}=\dfrac{\dfrac{1}{30}}{\dfrac{1}{33}}=\dfrac{1}{30}\cdot33=\dfrac{11}{10}=1\dfrac{1}{10}

A train travels from station A to C having distance of 285 miles in 6 hours. During the journey, it reaches intermediate station
Nesterboy [21]

Answer:

Distance between B and C = 3\times 55=165miles

Step-by-step explanation:

Let the time taken to reach from station A to B be x  hr

Let the time taken to reach from station B to C be y  hr

Given total time from station A to C be 6 hr

∴ x + y = 6

⇒ y = 6 - x → (1)

Also total distance given is 285 miles

As Distance=Speed\times Time

∴ distance travelled between station A and B

  =40\times xmiles

distance travelled between station B and station C

  =55\times ymiles

So, 40x + 55y = 285  

⇒ 40x + 55(6 -x) = 285     (From 1)

=> 40x + 330 - 55x = 285

=> -15x = 285 - 330

=> -15x = -45  ⇒ x=3

gives y = 6-3 = 3 hours


Distance between B and C = 3\times 55=165miles

46) through: (3, -5), perp. to y=-x-3<br> find slope intercept form
sweet-ann [11.9K]

Answer:

y = x - 8

Step-by-step explanation:

The equation of the straight line which is perpendicular to the straight line y = -x -3, will be y = x + c' ....... (1), where c' is a constant.

{This is because the product of the slopes of two mutually perpendicular straight line is -1}

Now, (3,-5) point satisfies equation (1).  

Hence, -5 = 3 +c', ⇒c' = -8.

Therefore, the equation of the required straight line in slope-intercept form is y = x - 8 (Answer)

{Note: The slope-intercept form of a straight line is y = mx + c, where m is the slope of the line i.e. tanФ, and c is the length of y-axis intercept.}
