R^2+6r-40 factor each expression

bearhunter [10]

(r + 10)(r - 4)

To double check:
r * r is r^2

10 * r = 10r; -4 * r = -4r
Combine to get 6r.

-4 * 10 = -40

snow_tiger [21]

Answer:

slope = -3/4

Step-by-step explanation:

Slope:

− 3/4

y-intercept:

13 /4

Any line can be graphed using two points. Select two values, and plug them into the equation to find the corresponding values.

x | y

0 | 13 /4

1 | 5/ 2

Adriana va a llenar bolsas de dulces para su fiesta de cumpleanos si tiene un paquete con 100 paletas y otro con 56 chocolates y

lions [1.4K]

Answer:

56 bags of a chocolate and a popsicle

Step-by-step explanation:

The first thing is to find the relationship between the number of popsicles and the number of chocolates, which would be the quotient of these:

100/56 = 1.78

Since it does not reach number two, you cannot add 2 popsicles and 2 chocolates, therefore the only way that they contain the same amount is that there is a chocolate and a popsicle, that is to say that a total of 56 bags would come out.

A population of 249 birds increases at a rate of 16% annually. jewel writes and exponential function of the form f(x)=abc to rep

Ad libitum [116K]

Answer:

a = 249 and b = 1.16

Step-by-step explanation:

Consider the provided information.

The exponential function for growth is: $y=a(1+ r)^x$

Here, a is the initial value and r is the rate of change.

It is given that the number of birds is 249.

It means a = 249

The rate is given 16%

r=0.16

Put the value of a and r in the above formula.

$y=249(1+0.16)^x$

$y=249(1.16)^x$

Now we will compare it with the exponential function form $y=ab^x$

Therefore, a = 249 and b = 1.16
