Verizon [17]

Answer:

x = 2 * (y/5) feets

Step-by-step explanation:

Given that :

Actual dimension of mural = 15 feet by 8 feet

Scale drawing = 2 feet : 5 feet

2 feets on the scale drawing represents 5 feets of the actual drawing.

Drawing length (x)

Actual mural length (y)

x = 2 * (y/5) feets

Hence, dimension of scale drawing:

x = 2 * (15/5) ; x = 2 * (8/5)

x = 6 feets ; 3.2 feets

Find a possible value of b. 5x2 - bx - 8​
pychu [463]

Answer:

Step-by-step explanation:

Without more input from you, it's hard to find an exact value for b.  However, b may take on a large range of values.  b = 10 and b = -3 (chosen arbitrarily) are acceptable choices.

Take a look at the quadratic formula.  The discriminant is b^2 - 4ac.  There is nothing about this equation that restricts or forbids the use of any value of b.
