How do I do a question 5* “I, J, k, and L

Mathematics
1 answer:
7nadin3 [17]3 years ago
3 0

Answer:

Step-by-step explanation:

5 (i)  243 ÷x = -81

243 ÷ -81 = x

x = -3

5 (j)  50 ÷ x = -50

    50 ÷ -50 = x

       x = -1

5(k)   -92 * x = 184

                 x = 184 ÷  -92

                 x = -2

5(l)    -800 ÷x = -20

       -800 ÷ -20 = x

       x = 40

Which is the first step in simplifying the expression?
Elenna [48]
\dfrac{3}{2 +  \sqrt{2} }

To rationalise the denominator, this is a standard step:
= \dfrac{3}{2 + \sqrt{2} } \times  \dfrac{2 - \sqrt{2}}{2 - \sqrt{2}}

Answer: Option A

---------------------------------------------------------------------------------------------------

Let me continue to complete the question, though it is not ask for

= \dfrac{3(2 - \sqrt{2})}{(2 + \sqrt{2)}(2 - \sqrt{2}) }

= \dfrac{3(2 - \sqrt{2})}{4 - 2 }

= \dfrac{6 - 2\sqrt{2}}{2 }

two ferries start moving toward each other from opposite riverbanks, a and b. when they pass each other for the first time, the
Usimov [2.4K]

Let 'x' be the distance from THE far bank   where 700 is the distance to the NEAR bank

boat one has travelled 700    (rate = 700/unit time)         boat two has travelled   x    rate = x / unit time

boat one then travels   x  + 400  more      and boat two travels   700 + (700+x -400) more    when they meet

The time is the same      rate x time = distance      distance/rate = time     equate the distances divided by the respective rates

(700 + x + 400)/700     =    (  x  +  700     +  (700+x-400) )/x

1100x + x^2 = 1400x + 700000

x^2-300x -700000 = 0                         quadratic formula yields  x = 1000  

One boat travels 700   the other   1000 whe they first meet.....width of river =   700+ 1000 = 1700 m

Geometry page 1 help please !
victus00 [196]

Answer:

16) y=\frac{1}{4}x +5

17) y = -x - 4

18) y = -2x - 1

19) y = -2x

20)y=\frac{-5}{3} -3

Step-by-step explanation:

With the two points you find the slope using \frac{y_{2}-y_{1}  }{x_{2}-x_{1} }

Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
