The function y=6+1.25x can be used to find the cost of joining an online music club and buying x songs from the website. Based o

Butoxors [25]

The y-intercept is obtained when we equate x to 0, where x is the number of songs bought. Thus, before buying any songs, $6 have to be paid. This is the cost of joining the the music club. The second statement is true.

A triangle has side lengths of (1.3f+2.9g)(1.3f+2.9g) centimeters, (1.1f-7.7h)(1.1f−7.7h) centimeters, and (2.3h+1.5g)(2.3h+1.5g

VikaD [51]

Answer:

Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.

Step-by-step explanation:

It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.

We have to find the expression which represents the perimeter, in centimeters, of the triangle.

Perimeter of a triangle = Sum of its all the sides.

$Perimeter=(1.3f+2.9g)+(1.1f-7.7h)+(2.3h+1.5g)$

On combining like terms, we get

$Perimeter=(1.3f+1.1f)+(2.9g+1.5g)+(-7.7h+2.3h)$

$Perimeter=2.4f+4.4g+(-5.4h)$

$Perimeter=2.4f+4.4g-5.4h$

Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.

Apply the distributive property to create an equivalent expression.

Amanda [17]

The distributive property: a(b + c) = ab + ac

(-7c + 8d)0.6 = (-7c)(0.6) + (8d)(0.6) = -4.2c + 4.8d
