Answer:

Option B: A triangle with side lengths 4 cm, 5 cm, and 15 cm

Step-by-step explanation:

Since we are dealing here majorly with sides, one condition is that each side has to be shorter than the sum of the other two sides and longer than their difference meaning that if we have a, b and c

The a value has to be shorter than the sum of b and c - a < b+c and the a value also has to be longer than their difference - a > b-c

In this example,we have side lengths 4 cm, 5 cm, and 15 cm. Taking a, b and c as 4 cm, 5 cm, and 15 cm respectively.

The sum of 5 and 4 is 9 and the third side 15 is greater than 9 when it is supposed to be less to construct a triangle.

2x + 3y = 6
cestrela7 [59]

Answer:

D)The slope is -2/3

Step-by-step explanation:

First, put this equation in slope-intercept form by subtracting 2x on both sides:

2x+3y=6

-2x. -2x

Your equation should be:3y=-2x+6

Then, divide the whole equation by 3 since y has to be by itself

3y=-2x+6

---- ------

3. 3

Your equation should be y=-2/3x+6

Since the slope in slope-intercept form is m in y=mx+b, -2/3×=m

Final answer:D) The slope is -2/3

Ivenika [448]
Okay, well 1 ton equals 2,000 pounds.
So if you have 6,000 pounds...
You have 3 tons!
Now to check:
2,000(1 ton) + 2,000 (1 ton) + 2,000 (1 ton) = 6,000

The sum of three numbers is -2. The sum of three times the first number, twice the second number, and the third number is nine.
Anna35 [415]

Answer:

The numbers are 3, 5, -10.

Step-by-step explanation:

Let, the numbers are X, Y, Z.

Given, sum of the three numbers are -2.  

So, the equation is X + Y+ Z = -2 .......(i)

Again, for 2nd condition, the equation will be  

3X + 2Y + Z = 9  ....... (ii)

Again, for the third condition, the equation will be

Y - (Z/2) = 10 ......(iii)

Multiplying the equation (i) by 3 and the equation (ii) by 1, we get

                     3X + 3Y+ 3Z = -6

<u>                      3X + 2Y +  Z =  9</u>

(Deduct)                  Y + 2Z = -15 ......(iv)  

Solving equation (iii) and (iv) we get,

                         Y - (Z/2) = 10

<u>                          Y + 2Z   = -15</u>

(Deduct)        -(Z/2) - 2Z = 25

or, (-Z-4Z)/2 = 25

or, -5Z = 25*2

or, Z = 50/(-5)

Therefore, Z = -10

Putting the value of Z into equation (iv) we get,

Y + 2*(-10) = -15

or, Y - 20 = -15

or, Y = 20 - 15

Therefore, Y = 5

Putting the value of Y and Z into equation (i) we get,

X + 5 + (-10) = -2

or, X + 5 - 10 = -2

or, X - 5 = -2

or, X = 5 - 2

Therefore, X = 3

So, the numbers are, X = 3; Y = 5; and Z = -10.
