Answer:

f(- 5) = 13

Step-by-step explanation:

Substitute x = - 5 into f(x)

f(x) = - 3x - 2 , then

f(- 5) = - 3(- 5) - 2 = 15 - 2 = 13

Simplify both sides of the equation

5x+2=244

Subtract 2 from both sides

5x+2−2=244−2
5x=242

Divide both sides by 5

$\frac{5x}{5} = \frac{242}{5}$

Answer

$\: x = \dfrac{242}{5}$

$\: x = 48.4$

In parallelogram FGHJ if m∡ GHJ=55˚ find m∡FGH

hodyreva [135]

Answer:

∠ FGH = 125°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, then

∠ FGH + ∠ GHJ = 180° , that is

∠ FGH + 55° = 180° ( subtract 55° from both sides )

∠ FGH = 125°

-18x

you first times the numbers, which becomes -18

Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)

Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)

-18x
