Answer:

x=-4

Step-by-step explanation:

3x-5=7x+11    Add like terms

   +5     +5

3x=7x+16       Do it again...

-7x   -7x

-4x=16        Now divide

x=-4

Answer:

The answer is x=-4

Step-by-step explanation:

3x-5=7x+11

1) you have to move the number that has a variable with it onto one side(3x and +7x) and the numbers that do not have a variable move them onto the other side (-5 and +11),but if you move them you have to change the sign like the underlined numbers below

3x-7x=5+11

2) you have to subtract 3x and-7x which it equals  -4x and then you have to add 5 and 11 which it equals 16

Equation now -4x=16

3) you have to divide -4x into -4x and also divide -4x into 16 which you will get x=-4

Answer:

840

Step-by-step explanation:

First you have to multiply 42 by 20. Because you have to find the total cost of the whole bag. Then a little guess and check you would get 16 lb of green tea and 4 lb of herbal tea. They both have to equal 20 lbs and $840. Multiply 16 by 40 then 50 by 4 then add them together you will get 840.

(-1,-3) (0,-5)

Step-by-step explanation:

Move dot at the origin to (-1,-3) down three and one to the left

Select other dot and move it to (0,-7)

Given:

A circle with center O.

[tex]m\angle MOP=45^\circ, m\angle PON=85^\circ[/tex].

To find:

The measure of arc MN.

Solution:

We know that,

[tex]m\angle MON=m\angle MOP+m\angle PON[/tex]

[tex]m\angle MON=45^\circ+85^\circ[/tex]

[tex]m\angle MON=130^\circ[/tex]

The central angles in equal to the measure of the corresponding arc.

[tex]Arc(MN)=m\angle MON[/tex]

[tex]Arc(MN)=130^\circ[/tex]

Therefore, the measure of arc MN is 130 degrees.

f(-12) = -12(-12) + 100 = 144 + 100 = 244

Answer:

244

Step-by-step explanation:

Substitute -12 as x.

f (-12) = -12(-12) + 100

f (-12) = 144 + 100

f (-12) = 244

lol your not the only lazy 1

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.

Answer:

25x-5

Step-by-step explanation:

Answer:

part 1:

1) AB = BC = 10

2) DE = sqrt(10² - 9²) = sqrt(19)

3) CED = 90⁰

4) BCD = (90⁰ - 53⁰).2 = 74⁰

part 2:

because FGHJ is a rhombus

=> GK = KJ

<=> 3x + 1 = x + 9

<=> 2x = 8

<=> x = 4

and we have:

GHK + FGK = 90⁰

<=> (4y - 8)/2 + y + 4 = 90⁰

<=> 2y - 4 + y + 4 = 90⁰

<=> 3y = 90⁰

<=> y = 30

5) with x = 4 => GJ = 2KJ = 2.(4 + 9) = 26

6) JK = 4 + 9 = 13

7) with y = 30, HFJ = 90 - FGK = 90 - 34 = 56⁰

8) HJF = 2.FGK = 2.34 = 68⁰

part 3:

because MNLO is rectangle

=> MP = PO

<=> 5a - 7 = 2a + 8

<=> 3a = 15

<=> a = 5

9) with a = 5, MO = 2.PO = 2.(2.5 + 8) = 2.18 = 36

10) NP = PO = 2.5 + 8 = 18

11) LM² = LN² - MN² = MO² - 26² = 36² - 26² = 620

=> LM = 2sqrt(156) = 24,9

12) tan NMO = NO/MN = LM/MN = 24.9/26

=> NMO = 43,8⁰

part 4:

because RSTU is square

=> SR = RU

=> 2k + 7 = 3k - 2

<=> k = 9

with k = 9 =>RU = SR = 2.9 + 7 = 25

13) RV = 1/2.SU = 1/2.sqrt(25² + 25²) = 17,7

14) SU = 2RV = 2.17,7 = 35,4

15) perimeter RSTU = 25.4 = 100

16) area RSTU = 25² = 625

Answer:

By making x = -3

Step-by-step explanation:

If X was -3 then -3 plus 3 equals 0, and 2 multiplied by 0 is 0, so the problem will have no solution.

Answer:

Either A or D, but the answer is [tex]f(x) = 3^x[/tex].

Step-by-step explanation:

We can check for exponential growth by checking for an [tex]x[/tex] in the exponent of a constant value in the function, which is this case for [tex]f(x) = 3^x[/tex].

f(x) = x + 3 function represents exponential growth. So the correct option is option is c.

An exponential function is a arithmetic function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is know the base of the function and it will be greater than 0.

An exponential function is explain by the formula f(x) = ax, where the input variable x take place as an exponent.

The exponential curve turn on the exponential function and it depends on the value of the x.

The exponential function is an main arithmetic function which is of the form

f(x) = ax

Exponential Growth

In Exponential Growth, the quantity grow very slowly at first, and then quickly. The rate of change growth over time. The rate of growth becomes faster as time passes. The quick growth is meant to be an “exponential increase”. The formula to explain the exponential growth is:

y = a ( 1+ r )x

Where r is the growth percentage.

Therefore, f(x) = x + 3 is a function represents exponential growth.
