Polynomials with the same roots can have different graphs. True? Or false?
Diano4ka-milaya [45]
True.

E.g. (x-1)(x-2) versus 100(x-1)(x-2)

They have same roots of x= 1 or 2, but the second equation is 100 times stretching of the first one vertically

a recipe requires 2.5 teaspoons of sugar to make a candy bar. which equation shows the number of teaspoons of sugar, y, needed t
padilas [110]
If you would like to know the equation that shows the number of teaspoons of sugar needed to make x candy bars, you can calculate this using the following steps:

2.5 teaspoons of sugar ... 1 candy bar
y teaspoons of sugar = ? ... x candy bars = ?

2.5 * x = 1 * y
2.5 * x = y
y = 2.5 * x

The correct result would be <span>y = 2.5 * x.</span>

Solve each inequality and graph its solution -2 ≤ n-1 ≤ 5
Novay_Z [31]

Answer:

Part 1)

Part 2)    

Part 3)

Part 4)  

Part 5)

Part 6)

Step-by-step explanation:      

Part 1)            

Multiply by -1 both sides

   

The solution is the interval -------> [-1.817,∞)

The solution in the attached figure N 1    

Part 2)      

rewrite

     

Multiply by -1 both sides

   

     

   

The solution is the interval--------> (0.09,∞)

The solution in the attached figure N 2

Part 3)

combine like terms

 

Adds 8 both sides

The solution is the interval--------> (-∞,6]

The solution in the attached figure N 3  

Part 4)    

Adds 5 both sides

Multiply by -1 both sides

Divide by 2 both sides

The solution is the interval--------> (-7,∞)

The solution in the attached figure N 4  

Part 5)

applying distributive property left side

Subtract 14 both sides

Divide by 7 both sides

The solution is the interval--------> (-∞,-13)

The solution in the attached figure N 5

Part 6)

applying distributive property left side

Adds 117 both sides

Divide by -1 both sides

Divide by 13 both sides

The solution is the interval--------> [-9.31,∞)  Answer:
