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)
Answer:
0
Step-by-step explanation:
It is 0 because the slope intercept form is y=mx+b right now you only have the y intercept which is the b of the equation. That means that your slope is non existence
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
Answer:
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.
