16x² +8-7x-3x2 - 13x

liq [111]

Answer:

$13x^{2}$ -20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

U would factor by grouping and get x^2(x-2) + 3(x-2) and then get (x^2 +3) (x-2)

(4⁰)-⁹

= 4⁰×-⁹

= 4⁰

(-4⁹)²

= -4⁹×²

= -4¹⁸

=( -4)¹⁸

(4-³)-³

= 4-³ × -³

= 4⁹

(4⁶)-³

= 4⁶ × -³

= 4-¹⁸

= 1/4¹⁸

Given ƒ(x) = −10x + 45, find x when ƒ(x) = 15.

Temka [501]

Answer:

x = 3

Step-by-step explanation:

Given

f(x) = - 10x + 45 and f(x) = 15, then equating gives

- 10x + 45 = 15 ( subtract 45 from both sides )

- 10x = - 30 ( divide both sides by - 10 )

x = 3
