-5x+7+2x-13<9 Please Explain
olganol [36]
Ok the answer is -5 less than 9 which is true lol


Anyways here’s how I got the answer

-5+7+2x-13 less than 9

Combine like terms in this case it’s -5 and 2, and the other is 7 and -13

-5+2= -3
7-13= -6

Ok now that that’s done here’s the next step

-3x-6 less than 9 solve it


-3x-6 < 9
+6< +6

-3x < 15



Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5

And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)

Suppose y varies inversely with x. Write an equation if y=7 when x=-4
luda_lava [24]

Answer:

y = -28 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.

So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x

K = constant, we have to work this out

7 = k ÷ -4

7 × - 4 = k

k = - 4 × 7

k = -28

k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x

Two boats left a base camp at bearing of S60°E and S50°W at speeds of 50km/h and 70km/h respectively. Find the distance between
ivolga24 [154]

Answer:

  • 197.93 km

Step-by-step explanation:

Let the base camp is point A and boats' locations after two hours are points B and C.

By connecting the three points together we get a triangle ABC with sides:

  • AB = 50*2 = 100 km
  • AC = 70*2 = 140 km

The angle between AB and AC is:

  • 60 + 50 = 110 degrees (opposite directions from south)

We are looking for the distance BC, which can be found by using the law of cosines:

  • BC² = AB² + AC² - 2AB*AC*cos ∠BAC
  • BC² = 100² + 140² - 2*100*140*cos 110°
  • BC²  = 39176.56 (rounded)
  • BC = √39176.56 = 197.93 km (rounded)

The distance between the boats is 197.93 km.
