If a line with slope = 2 passes through the points (4,-8) and (x,2), find x

Mathematics

Deffense [45]2 years ago

Answer:

x = 9

Step-by-step explanation:

Calculate the slope m using the slope formula then equate to 2

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (4, - 8) and (x₂, y₂ ) = (x, 2 )

m = \frac{2+8}{x-4} = \frac{10}{x-4} = 2 ( multiply both sides by x - 4 )

2(x - 4) = 10 ( divide both sides by 2 )

x - 4 = 5 ( add 4 to both sides )

x = 9

What is the volume of this cylinder? *
Juli2301 [7.4K]

Answer   V≈351.86

Step-by-step explanation: V=πr2h=π·42·7≈351.85838

The formula for the volume of a cylinder is V=Bh  or  V=πr2h .

The radius of the cylinder is 4 cm and the height is 7 cm.

Substitute 4 for r and 7 for h in the formula V=πr2h .

V= pie (4)² (7)

v= pie ( 14) (49)

Adding =[tex]15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17} we get 73

Option D is correct

Step-by-step explanation:

We need to find the sum of: 15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17}

Converting mixed fractions into improper fraction

15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17}

=\frac{189}{12}+\frac{149}{17}+\frac{279}{12}+\frac{429}{17}

Taking LCM of 12 and 17 we get 204

=\frac{189*17+149*12+279*17+429*12}{204}

=\frac{3213+1788+4743+5148}{204}

=\frac{14892}{204}

=73

So, adding =[tex]15\frac{9}{12}+8\frac{13}{17}+23\frac{3}{12}+25\frac{4}{17} we get 73

Option D is correct
