Answer:

True, A

Step-by-step explanation:

If you sum two different sides of a traingle it must be greater than the remaining one

We can test that by adding the two smallest sides

1+8=9

9 is obviously greater than 8, so the answer is: true

The temperature in Celsius would be,

elena-14-01-66 [18.8K]

First derisive the equation for C

$\\ \sf\longmapsto F=\dfrac{9}{5}C+32$

$\\ \sf\longmapsto C+32=\dfrac{5}{9}F$

$\\ \sf\longmapsto C=\dfrac{5}{9}F-32$

F=101F

$\\ \sf\longmapsto C=\dfrac{5}{9}101-32$

$\\ \sf\longmapsto C=\dfrac{505}{9}-32$

$\\ \sf\longmapsto C=56.1-32$

$\\ \sf\longmapsto C=24.1°C$

Find the equation in standard form of the line passing through the points 3,-4 and 5,1

aliina [53]

Answer:

5x - 2y - 23 = 0

Step-by-step explanation:

Line is passing through the points $(3,\:-4)= (x_1, \:y_1) \: \&\: (5,\: 1)= (x_2,\:y_2)$

Equation of line in two point form is given as:

$\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \: \frac{y -( - 4) }{ - 4 -1} = \frac{x -3 }{3 -5 } \\ \\ \therefore \:\frac{y + 4 }{ - 5} = \frac{x -3 }{ - 2 } \\ \\ \therefore \: \frac{y + 4 }{ 5} = \frac{x -3 }{ 2 } \\ \\ \therefore \: 2(y + 4) = 5(x - 3) \\ \therefore \: 2y + 8 = 5x - 15 \\ \therefore \: 5x - 15 - 2y - 8 = 0 \\ \red{ \boxed{ \bold{\therefore \: 5x - 2y - 23 = 0}}} \\ is \: the \: required \: equation \: of \: line \: in \: \\ standard \: form.$

-4004 + 2023 – 24x2 – 2 / – 2x2 + 2x + 1?

Kamila [148]

Answer:

388.5/x

Step-by-step explanation:

multiply:

(-4004+2023-48-2)/ -4 + 2x +1

Simplify:

-2031/ -3 +2x

divide by -3

677/2x

388.5 / x

as simple as you can go

hope this helps!
