Answer: Option A  is the graph for given function y=(x-2)(x+5)

Explanation:  we have  given function y = (x-2)(x+5)

which is a quadratic meaning the equation in which highest degree is two

and graph of a quadratic equation is a parabola.

In case of  (x-2) graph will shift two units right along x-axis.

In case of  (x+5) graph will shift 5 units left along x-axis.

it will cover left and right side of x-axis.

In option B graph is only on left side which is not satisfying given points

In option C graph is only on right side which is satisfying given points

What is a counterexample for the statement the difference between two integers is always positive
Maru [420]

We have to give counter example for the given statement:

"The difference between two integers is always positive"

This statement is not true. As integers is the set of numbers which includes positive and as well as negative numbers including zero.

Consider any two integers say '2' and '-8'. Now, let us consider the difference between these two integers.

So, 2 - 8

= -6 which is not positive.

Therefore, it is not necessary that the difference of two integers is only positive. The difference of two integers can be positive, negative or zero.

You have been saving nickels, dimes, and quarters in a jar for about a year. You decide to see how much money you've saved up. W
anyanavicka [17]

Answer:

x = number of nickels = 127

y = number of dimes = 156

z = number of quarters = 78

Step-by-step explanation:

Let

x = number of nickels

y = number of dimes

z = number of quarters

Total worth of the coins = $41.45

Total number of coins = 361

x + y + z = 361 (1)

dime = $0.1,

nickel = $0.05

quarter = $0.25

0.05x + 0.1y + 0.25z = 41.45 (2)

twice as many dimes as quarters.

y = 2z

Substitute y = 2z into (1) and (2)

x + 2z + z = 361

0.05x + 0.1(2z) + 0.25z = 41.45

x + 3z = 361

0.05x + 0.2z + 0.25z = 41.45

x + 3z = 361 (3)

0.05x + 0.45z = 41.45 (4)

Multiply (4) by 20

x + 3z = 361 (3)

x + 9z = 829 (5)

Subtract (3) from (5)

9z - 3z = 829 - 361

6z = 468

Divide both sides by 6

z = 468 / 6

= 78

z= 78

Recall,

y = 2z

= 2(78)

= 156

y = 156

Substitute the value of y and z into

x + y + z = 361

x + 156 + 78 = 361

x + 234 = 361

x = 361 - 234

= 127

x= 127

x = number of nickels = 127

y = number of dimes = 156

z = number of quarters = 78

What's three equivalent ratios for 6/9
vaieri [72.5K]

Answer:

Three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27

Step-by-step explanation:

An equivalent ratio refers to the same number but written differently. For example, for the ratio 6/9, we could obtain the following equivalent ratios.

First equivalent ratio

You can divide the numerator and denominator by 3. You get 2/3

\frac{6\div 3}{9\div 3}=\frac{2}{3}

Second equivalent ratio

You can multiply the numerator and denominator by 2. You get 12/18

\frac{6\times 2}{9\times 2}=\frac{12}{18}

Third equivalent ratio

You can multiply the numerator and denominator by 3. You get 18/27

\frac{6\times 3}{9\times 3}=\frac{18}{27}

Thus, three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
