Answer:

I like to compare them all the same. Put all the equations in slope intercept form y=mx+b

So you need to isolate y.

Step-by-step explanation:

Main equation to compare y=2/3x + 4

If they have the same slope they are parallel. If they have opposite reciprocal slopes then they are perpendicular.

First one is y=2x +12 neither

Second one is y= -3/2x -1 perpendicular

Third one is y= 2/3x - 1 parallel

Forth one is y= 2/3x + 11/3 parallel

Find the interest using the formula I = Prt Principal: $1800 Interest Rate: 6.5% Time: 30 months Interest =

Oliga [24]

I = P r t

I = (1800) (6.5÷100) (30÷12)

I = (1800) ( 0.065) (2.5)

I = 292.50$

The base of a triangle is 9/4 times of its height. If the area of triangle is 144 cm2. Find the height and the base.

Mazyrski [523]

Step-by-step explanation:

Given that the base of triangle is 9/4 times of its height . And area is 144 cm² . Let the height be h , then its base be 9h/4 .

• According to Question :-

$\tt\to Area_{(\triangle)}=\dfrac{base\times height}{2}\\\\\tt\to 144cm^2 = \dfrac{9h\times h}{4\times 2 } \\\\\tt\to h^2 =\dfrac{12\times 12 \times 2 \times 2 }{3\times 3 }\\\\\tt\to h =\sqrt{\dfrac{12\times 12 \times 2 \times 2 }{3\times 3 }}\\\\\tt\to h =\dfrac{(12)(2)}{3} \\\\\tt\to \boxed{\orange{\tt h = 8 cm }}$

Therefore ,

Height = h = 8cm .
Base ,= 9h/4 = 18cm .
