Answer:

y=3x+2

Step-by-step explanation:

y is going up by 3 as x goes up by 1 so slope=3/1=3.

We can use this pattern to determine what will happen at x=0 (the y-intercept). 5-3=2 so the y-intercept is 2.

Slope-intercept form is y=mx+b where m is slope and b is y-intercept.

The equation is y=3x+2.

Original price $29.99, markdown is 33 1/3%

Allushta [10]

Subtract 33.333% from 100%; you'll get 66.667%.

Mult the original price by 0.66667: ($29.99)(0.667) = $20.00 (answer)

This answer reflects a 33.333% discount from the regular price of the item.

What is x?<br> 7(x – 5) = 9x – 3

Mkey [24]

Answer:

x = -16

Step-by-step explanation:

$7(x-5) =9x-3 \\7x -35 = 9x - 3\\3- 35 = 9x - 7x\\-32 = 2x\\x = \frac{-32}{2}\\\huge \red{\boxed{x = -16}}$

Pachacha [2.7K]

Answer:

a = 9.849

b = 20.25

c = 491.03

Step-by-step explanation:

By using Pythagoras theorem in the right triangle BDC,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

BC² = BD² + DC²

a² = 9² + 4²

a = $\sqrt{(81+16)}$

a = $\sqrt{97}$

a = 9.8489

a ≈ 9.849 units

By mean proportional theorem,

$\frac{\text{DC}}{\text{BD}}=\frac{\text{BD}}{\text{AD}}$

AD × DC = BD²

b × 4 = 9²

b = $\frac{81}{4}$

b = 20.25 units

BY Pythagoras theorem in ΔADB,

AB² = AD² + BD²

c² = b² + 9²

c² = (20.25)² + 9²

c² = 410.0625 + 81

c = 491.0625

c = 491. 063 units
