x=?? hurry i will give brainliest

Answer:

x=-2 and x=-8

Step-by-step explanation:

(x+5)=3

Subtract 5 from both sides, to isolate x

x=-2

-(x+5)=3

Distribute the -

-x-5=3

Add 5 to both sides to isolate x

-x=8

Multiply both sides by -

x=-8

Step-by-step explanation:

Answer: -5/3

Step-by-step explanation:

12(b + 2) + 3b = -1

12b + 24 + 3b = -1

15b + 24 = -1

15b = -1-24

b = -25/15 = -5/3

The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.

Given the equation in the question:

12( b + 2 ) + 3b = -1

To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.

Distribute the 12 across the terms inside the parentheses:

12( b + 2 ) + 3b = -1

12×b + 12×2 + 3b = -1

Simplifying, we get:

12b + 24 + 3b = -1

Collect and combine the like terms on the left side of the equation:

12b + 3b + 24 = -1

15b + 24 = -1

Subtract 24 from both sides of the equation:

15b + 24 - 24 = -1 - 24

15b = -1 - 24

15b = -25

Divide both sides by 15:

b = -25/15

Simplify

b = -5/3

Therefore, the value of b is -5/3.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable

The exponential function is given in the question, as follows:

f(x) = 3(2/3)ˣ

As per the given function, the y-intercept is (0, 3) which is shown in the attached figure.

Hence, the required graph has been attached below which represents the given exponential function.

Answer:

The answer is 1690, and then 1630

Step-by-step explanation:

2050, 1990, 1930, 1870, 1810, 1750, 1690, 1630

Each number is going down by 60

===============================================================

Explanation:

This is an arithmetic sequence. We are adding -60 to each term to get the next term. Put another way, we are subtracting 60 from each term to get the next.

term 1 = 2050

term 2 = (term1) + (-60) = (term1) - 60 = 2050 - 60 = 1990

term 3 = (term2) + (-60) = (term2) - 60 = 1990 - 60 = 1930

term 4 = (term3) + (-60) = (term3) - 60 = 1930 - 60 = 1870

and so on

Keeping this pattern up, we get these next two terms

1750 - 60 = 1690

1690 - 60 = 1630

which are the two answers

-----------

If you want to use a formula, then a1 = 2050 is the first term and d = -60 is the common difference. We get this nth term formula

a(n) = a1 + d(n-1)

a(n) = 2050 + (-60)(n-1)

a(n) = 2050 - 60n + 60

a(n) = -60n + 2110

Then note that six terms of the sequence are given to us. This means we want to find the 7th term, so we plug in n = 7 to get

a(n) = -60n + 2110

a(7) = -60(7) + 2110

a(7) = -420 + 2110

a(7) = 1690

The 7th term is 1690

Repeat for n = 8

a(n) = -60n + 2110

a(8) = -60(8) + 2110

a(8) = -480 + 2110

a(8) = 1630

The 8th term is 1630

Answer:

For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula

Step-by-step explanation:

The great pyramid of Cheops is a square based pyramid therefore we have;

V + F = E + 2

Where:

V = Vertices

F = Faces

E = Edges

Hence, we have for a square pyramid;

V = 5 vertices (One at the peak, and four  at the base edges)

F = 5 faces (The four lateral or side faces and the base)

E = 8 edges ( The four lateral edges and the four base edges)

Hence;

5 + 5 = 8 + 2 which proves Euler-Descartes formula.

Answer:

red = 3/13

yellow = 6/13

blue= 4/13

Step-by-step explanation:

breainliest really needed!!

The probability of selecting the red marble and yellow marble is 18/169.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a bag contains 3 red, 4 blue, and 6 yellow marbles.

Total number of outcomes = 3+4+6=13

Probability of selecting red marble = 3/13

Probability of selecting yellow marble = 6/13

So, P(red and yellow) = 3/13 × 6/13

= 18/169

Therefore, the probability of selecting the red marble and yellow marble is 18/169.

Answer:

The twentieth term is 50.

Step-by-step explanation:

The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:

a1 = 3*1 - 10

a1 = -7

Therefore to find the twentieth term we need to make n equal to 20. This is done below:

a20 = 3*20 - 10

a20 = 60 - 10

a20 = 50

The twentieth term is 50.
