Answer:

[tex]9x + 5y < 7[/tex]

this is the way u perfom enequality therom

now weite ur answer

Step-by-step explanation:

Triangle inequality theorem =The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

9 + 5 > 7

14 > 7 (True) ✔

5 + 7 > 9

12 > 9 (True) ✔

9 + 7 > 5

16 > 5 (True) ✔

So these side measures form a triangle.

hope you understood.

#since the x in (x) changed into (3) this means that the x change into (3)

f(3) = -4(3) + 1

f(3) = -12 + 1

f(3) = -11

Answer:

3

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -9 -0)/(4 - 7)

   = -9/-3

   = 3

Answer:

9.

Step-by-step explanation:

First solve 1+2. That is 3.

6/2 is 3.

So then we have 3 x 3, which is 9.

Answer: $1,146 billion

Step-by-step explanation:

First find the number of years between 2004 and 2017.

= 2017 - 2004

= 13 years

To find out such answers, use the future value formula which shows the value of an amount being increased by a certain percentage over a number of periods.

Future value = Amount * ( 1 + rate) ^ number of periods

= 500 * ( 1 + 5%) ¹⁷

= $1,146 billion

Given:

The two ways table.

To find:

The number of girls in year 9.

Solution:

Using the two ways table, we get

Boys in year 10 = Total student in year 10 - Girls in year 10

                        = 256 - 123

                        = 133

Boys in year 9 = Total boys - Boys in year 10 - Boys in year 11

                        = 407 - 133 - 125

                        = 149

Girls in year 9 = Total students in year 9 - Boys in year 9

                       = 303 - 149

                       = 154

Therefore, the number of girls in year 9 is 154 and the correct option is C.

Answer:

90 degrees

Step-by-step explanation:

in a square the diagonals always intersect to form 90 degree angles.

Answer:

y= -3x -7

Step-by-step explanation:

You can either use y= mx+b or y-y1=m(x-x1)

I will use y= mx+b

y=mx+b

(-3,2) = (x,y) = -3 is x and 2 is y

-3 =m= slope

y=mx+b

2=-3(-3)+b  

2= -3 x-3 +b

2= 9+b

you then subtract 9 on both sides because now 9 is positive so you subtract it.

2=9+b

-9 on both sides

-7= b and the final answer is above

your welcome! :)

Answer:

B

Step-by-step explanation:

Remark

I have to represent f(x) as plus +f(x)

I like to show this situation as +f(g(x)) which I think is much clearer.

+f(x) = 5x - 4    

Solution

+f(g(x)) = 5(g(x)) - 4  What has happened is that wherever you see an x on the right you put in g(x).

Now on the right, you put whatever g(x) is equal  to.

+f(g(x)) = 5(x^2 - 1)  - 4    

Remove the brackets.

+f(g(x)) = 5x^2 - 5 - 4

And make x = 0

+f(g(0)) = 5*0 - 5 - 4

+f(g(0)) = - 9

Answer:

Initial value: $25; Rate of change: 48; Equation: y= 8x + 25

Step-by-step explanation:

The initial value would be the $25 due to the fact that that's how much money she made during training. After that, her money will go up by $8 for every hour she works for, which is why that's the rate of change.

The equation just restates all that, the rate of change is always represented by the mx in the equation (8 replaces the m), and 25 replaces the b, the start of the line, or on a graph, where the initial dot would be on the y-axis.

Answer: B) 20.25

Step-by-step explanation:

22.5% = 0.225

22.5% of 90 = 0.225 * 90 = 20.25

Hope it helps and lmk if you need more info <3 :D

Answer:

B. 20.25

Step-by-step explanation:

22.5 percent *90 =

(22.5:100)*90 =

(22.5*90):100 =

2025:100 = 20.25

Step-by-step explanation:

Answer:

1+2=3 is answer

Step-by-step explanation:

so what help u need?

Answer:

x=3

Step-by-step explanation:

The problem can be re-written as :

[tex] \sqrt{3^{x} } \div \sqrt{3} = 3[/tex]

This is because x to the power of 1/2 is the same as the square of x.

multiply both sides by sqrt3

[tex] \sqrt{3^{x} } = 3 \sqrt{3} [/tex]

square both sides

[tex]3 ^{x} = (3)^{2} ( \sqrt{3} )^{2} [/tex]

simplify

[tex]3 ^{x} = 9 \times 3[/tex]

3 to the power of x is equal to 27

3 cubed (to the power of 3) is 27

so x is equal to 3.
