Answer:

Below

Step-by-step explanation:

1. Linear because it is of the form y = mx + b. The variable x is of the first degree.

The coefficient of x (1/3) ( = slope) is positive so it is increasing.

2. This is non-linear because the variable x is an exponent.

3. Because its of the second degree (x^2) - it is non-linear.

(3 + 5) * 2Y = (5 * 8) - (2 * 4)

julia-pushkina [17]

Answer:

Y = 2

Step-by-step explanation:

Solve for Y:

(3 + 5)×2 Y = 5×8 - 2×4

3 + 5 = 8:

8×2 Y = 5×8 - 2×4

5×8 = 40:

8×2 Y = 40 - 2×4

-2×4 = -8:

8×2 Y = -8 + 40

8×2 = 16:

16 Y = 40 - 8

40 - 8 = 32:

16 Y = 32

Divide both sides of 16 Y = 32 by 16:

(16 Y)/16 = 32/16

16/16 = 1:

Y = 32/16

The gcd of 32 and 16 is 16, so 32/16 = (16×2)/(16×1) = 16/16×2 = 2:

Answer: Y = 2

I need to solve for x. I'm so confused with the whole 'Slide splitting theorem' thing

Murljashka [212]

Triangles JFE and JLK are similar provided that line segments FE and LK are parallel. This means that corresponding parts of these triangles occur proportionally to one another. In particular,

$\dfrac{JF}{JL}=\dfrac{JE}{JK}=\dfrac{FE}{LK}$

From this relation we get

$\dfrac{JF}{JL}=\dfrac{JE}{JK}\implies\dfrac{(3x+21)-12}{12}=\dfrac{56}{70}$

Now we can solve for $x$ :

$\dfrac{3x+9}{12}=\dfrac45$

$3x+9=12\cdot\dfrac45=\dfrac{48}5$

$3x=\dfrac{48}5-9=\dfrac35$

$x=\dfrac{\frac35}3=\dfrac15$
