You have to multiply to get a simple equation so it would be 15x+45=15x-2x+10 and that’s where my knowledge stops with that

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Let's solve your equation step-by-step.

5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )

Step 1: Simplify both sides of the equation.

5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )

( 5 ) ( 3x ) + ( 5 ) ( 9 ) + −2x = 15x + ( −2 ) ( x ) + ( −2 ) ( −5 ) ( Distribute )

15x + 45 + −2x = 15x + −2x + 10

( 15x + −2x ) + ( 45 ) = ( 15x + −2x ) + ( 10 ) ( Combine Like Terms )

13x + 45 = 13x + 10

13x + 45 = 13x + 10

Step 2: Subtract 13x from both sides.

13x + 45 − 1 3x = 13x + 10 − 13x

45 = 10

Step 3: Subtract 45 from both sides.

45 − 45 = 10 − 45

0 = −35

Answer: 6 meters

Step-by-step explanation:

I had this question and got the answer right.

The distance from the base of the tree will be 6 meters.

The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.

Given that a bird is perched eight meters up in a tree. The bird is 10 meters away from you where you are standing.

From the Pythagorean theorem, the base will be calculated as:-

H² = P² + B²

B = √ ( H² - P² )

B = √ ( 10² - 8² )

B = √36

B = 6 meters

Hence, the 6 meters will separate you from the tree's base.

If the central bank increases the money supply by $100 billion and the velocity of money by 3, then the nominal GDP will increase by $300 billion.

Mark brainlist plz

The value of nominal GDP, when the central bank increases the money supply by $100 billion, and the velocity of money is 3, is 300.

What is the equation of exchange?

The equation of exchange can be given as,

[tex]M\times V=P\times Q[/tex]

Here, (M) is the money supplied, (V) is the velocity of the money, (P) is level of price and (Q) is Real GDP.

The central bank increases the money supply by $100 billion, and the velocity of money is 3. Here, we have,

[tex]M=300\\V=3[/tex]

The product of level of price and Real GDP is nominal GDP.

[tex]M\times V=P\times Q\\100\times 3=\text{Nominal GDP}\\\text{Nominal GDP}=300[/tex]

Thus, the value of nominal GDP, when the central bank increases the money supply by $100 billion, and the velocity of money is 3, is 300.

6x2y2 - 9xy - 42  =   3 • (2x2y2 - 3xy - 14)

The complete factorization of 6x^2y^2-9xy-42 is 3 (2x^2y^2 - 3xy - 14).

factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

Answer:

Step-by-step explanation:

You have to use the arithmetic sequence

f(n)=f(n-1)+d

You can plug in (40,10) and (50,20)

(10)=f(1)+39d

(20)=f(1)+19d

subtract

-10=20d divide

d=-1/2

plug into one of the equations above

(10)=f(1)+39(-1/2)

10=f(1)-39/2

59/2=f(1)

f(1)=29.5

plug into formula

f(n)=29.5-1/2(n-1)

f(n)= -1/2n +30 final equation (Plug in the table values into "n") to solve

Answer:

if it was like that wouldnt it go from 10 to 20 to 30 to 40 ect.

Step-by-step explanation:

The evaluation of the expression 2y + 10 + y² at y = 8 returns 90 as its value.

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

The considered expression is 2y + 10 + y²

We need to evaluate it at y = 8

Putting 8 in place of y in the expression, we get:

[tex]2y + 10 + y^2|_{y=8} = 2 \times 8 + 10 + (8)^2 = 16 + 10 + 64 = 90[/tex]

Note that small subscript of y = 8 shows that we're evaluating the expression for y = 8.

Also, when symbols are used with multiplication, we usually hide the multiplication sign and just keep the multiplying quantities close to each other, this is why [tex]2 \times y[/tex] was written 2y in the expression.

Thus, the evaluation of the expression 2y + 10 + y² at y = 8 returns 90 as its value.

We have,

the salary increases from $12,000 to $15,000

So, Change in Amount= (15,000 - 12,000)

= 3, 000

Now, Percent increase = change in amount/ original amount x 100

= 3000/ 12000 x 100

Answer:

3,21 is

2,21 is not a proper ordered pair.

Step-by-step explanation:

Remark

It's not a solution

You can either use the x value to find out the proper y value

or

You can use the y value to find out the proper x value

Proper y value

Let x = 2

y = 7*2

y = 14

So the proper y value given that x = 2 is 14.

Proper x value

Let y = 21

21 = 7x                    Divide both sides by 7

21/7 = 7x/7

3 = x

But (2,21) is not a solution. (3,21) is.
