Answer:

-2

The problem:

y=f(x)=x^2+x

find the slope of the secant line joining (-3,f(-3)) and (0,f(0))

Step-by-step explanation:

We need to first find the values that correspond to f(-3) and f(0).

f(-3) can be found by replacing the x's in f(x)=x^2+x with (-3):

f(-3)=(-3)^2+(-3)

f(-3)=9+-3

f(-3)=6

f(0) can be found by replacing the x's in f(x)=x^2+x with (0):

f(0)=(0)^2+(0)

f(0)=0+0

f(0)=0

So we want to find the slope of the line going through the points:

(-3,6) and (0,0)

Line them up-doesn't matter which point goes on top:

(-3,6)

(0,0)

---------Now subtract!

-3 , 6

The rise goes over the run so the slope is 6/-3 which simplifies to -2.

inessss [21]

Answer:

The required inequality is: 6\leq x

Step-by-step explanation:

Consider the provided information.

Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money, but he must work fewer than 16 hours this week.

Let the number of hours Gurnaz work is represented by x.

Gurnaz will need to work for at least six hours to save enough money,

That means he can work 6 or more than 6 hours,

x\geq 6

He must work fewer than 16 hours this week. That means the value of x should be less than 16.

x

Thus, the required inequality is: 6\leq x

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ or ≥ and use a open circle to represent < or >.

The value of x is greater than or equal to 6 also the value of x is less than 16. The required graph is shown below.

I round to 900 I have twice as many hundreds as ones and all my digits are different but their sums are 18 can someone answer th
stellarik [79]

Answer:

The number of once is 9.1  

The number of hundreds is 8.9

Step-by-step explanation:

Given as :

The total of digits having ones and hundreds = 900

The sum of digits = 18

Let The number of ones digit = O

And The number of hundreds digit = H

So, According to question

H + O = 18             .........1

100 × H + 1 × O = 900          ........2

Solving the equation

( 100 × H - H ) + ( O - O ) = 900 - 18

Or, 99 H + 0 = 882

Or , 99 H = 882

∴   H = \frac{882}{99}

I.e H = 8.9

Put the value of H in eq 1

So, O = 18 - H

I.e  O = 18 - 8.9

∴    O = 9.1

So, number of once = 9.1

number of hundreds = 8.9

Hence The number of once is 9.1  and The number of hundreds is 8.9

Since 6 is positive, it's (x+blank)^2

6/2=3, and (x+3)^2 = x^2+6x+9. We have x^2+6x-2, so we have to add 9 to both sides to get (x+3)^2-2=9, then subtract 9 from both sides to get
(x+3)^2-11=0, or (x+3)^2=11. Square root both sides to get x+3=sqrt(11), and x=sqrt(11)-3, which is approximately 0.32
