Which inequality represents the values of x that ensure triangle ABC exists? a triangle with side lengths of 6.5 units, 3.5 unit
kaheart [24]

Answer:

D. -3.0 < x < 7.5

Step-by-step explanation:

Given the side lengths of a triangle: 6.5 units, 3.5 units, and 2.5 + x units

For the triangle to exist:

  • A side length cannot be negative
  • A side length cannot be zero

Therefore, the third side length

x+2.5>0

x>-2.5

x must be greater than -2.5 and less than or equal to 6.5 units.

The correct option is D which satisfies this condition.

D. -3.0 < x < 7.5

Answer:

{ \underline{ \sf{\int\limits^2_1 {x^{2}-8x+8 } \, dx}  \: =  \:  - 1}}

Step-by-step explanation:

{ \tt{\int\limits^2_1 {x^{2}-8x+8 } \, dx}} \\  \\ =  { \tt{[ \frac{ {x}^{3} }{3}  - 4 {x}^{2}  + 8x ] {}^{2} _{1}}}

Substitute x with the limits:

= { \tt{( \frac{ {2}^{3} }{3}  - 4( {2)}^{2} + 8(2)) - ( \frac{ {1}^{3} }{3}  - 4( {1)}^{2}  + 8(1)) }} \\  = { \tt{( \frac{8}{3}  -  \frac{11}{3} )}} \\  \\  = { \tt{ - 1}}

Write an equation that represents the line. (1,-1),(3,-5)​
geniusboy [140]

Answer:

x+y=0

Step-by-step explanation:

slope m of given equations is

(-5+1)÷(3+1)

=-1

then the equations of this line is

y-(-1)=m(x-1)

or, y+1=-1(x-1)

or, y+1= -x+1

or, x+y=0

x+y=0 is required equation of line.
