graph the equation below using slope intercept form y=-3x+8

Answer: x=4

Step-by-step explanation:

Simplify the left side of 9x-3x-5=19 by combining like terms:

6x-5=19

Add 5 to both sides:

(6x-5)+5=19+5

Simplify:

6x=24

Divide both sides by 6:

(6x)/6=24/6

Simplify:

x=4

Given that,

The equations : 2f-5g=-9  and -7f+3g=4

To find,

The solution of the above equations.

Solution,

We have,

2f-5g=-9  ....(1)

-7f+3g=4 ......(2)

Multiply equation (1) by 7 and equation (2) by 2.

14f-35g=-63  ....(3)

-14f+6g=8 ......(4)

Add equation (3) and (4)

14f-35g -14f+6g = -63 + 8

-29g = -55

g = 55/29

g = 1.89

Put the value of g in equation (1).

2f-5(1.89)=-9

2f = -9+5(1.89)

f = 0.225

Hence, the solution of the above equations are g = 1.89 and f = 0.225.

Answer:

3x+20y

Step-by-step explanation:

First write down the expression.

5(x + 5y) - {2x – [3x – 3(x – 2y) + y]}

Now, the first thing you would have to do is the first parenthesis

5(x+5y)

5x+25y

So far, the expression looks like this: 5x+25y - {2x – [3x – 3(x – 2y) + y]}

No we would do the smallest parenthesis in the expression.

Which is: (x – 2y)

But since there is nothing to simplify, we move on

Next one is  [3x – 3(x – 2y) + y]

We have to do 3(x-2y) first

This is equal to: 3x-6y

So far, the expression looks like this:5x+25y - {2x – [3x – 3x-6y + y]}

The next step is still in the other parenthesis up top

Which is: [3x – 3x-6y + y]

We have to add up the x's and y's

Which is -5y

Our expression now looks like this:5x+25y - 2x-5y

Since we don't have anymore parenthesis, we look for the same letter and add or subtract them.

We have to do 5x-2x=3x

25y-5y=20y

So that means our final answer is :3x+20y

Hope this answer is correct!

Answer:

7536 [tex]km^3/sec[/tex]

Step-by-step explanation:

Given that:

Rate of decreasing of radius = 12 km/sec

Height of cylinder is fixed at = 2.5 km

Radius of cylinder = 40 km

To find:

The rate of change of Volume of the cylinder?

Solution:

First of all, let us have a look at the formula for volume of a cylinder.

[tex]Volume = \pi r^2h[/tex]

Where [tex]r[/tex] is the radius and

[tex]h[/tex] is the height of cylinder.

As per question statement:

[tex]r[/tex] = 40 km (variable)

[tex]h[/tex] = 2.5 (constant)

[tex]\dfrac{dV}{dt} = \dfrac{d}{dt}\pi r^2h[/tex]

As [tex]\pi, h[/tex] are constant:

[tex]\dfrac{dV}{dt} = \pi h\dfrac{d}{dt} r^2\\\Rightarrow \dfrac{dV}{dt} = \pi h\times 2 r\dfrac{dr}{dt} \\$Putting the values:$\\\Rigghtarrow\dfrac{dV}{dt} = 3.14 \times 2.5\times 2 \times 40\times 12 \\\Rigghtarrow\dfrac{dV}{dt} = 7536\ km^3/sec[/tex]

Answer:

Sharon is 36

Her daughter is 7 years and 2 months

Step-by-step explanation:

sharon is 5× as old

her daughter is written as 1 (because we dont know about her age)

then square root of 256 to find square which is equal as said in the queston:which is 16

algebraic equation would be:5n+16 (n represents the years and 5 is how many times older sharon is and 16 is how old their square sum of agewas 4 years ago)

Their present age would be:

Sharon=5x4+16=36

Daughter =36÷5=7 years 2 months

The present age of Sharon is 20 and the Present age of her daughter is 4.

A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation. A variable, coefficients, and constants make up an algebraic equation in most cases.

Given, Sharon is five times her daughter's age. The square of their ages was equal to 256 four years ago. Let the age of Sharon is x and the age of her daughter be y.

Thus the algebraic equation formed as per the given data is,

x = 5*y (Present age)

(x-4 + y -4)^2 = 256 (Four years ago)

Taking square root both the sides

x + y = 24

comparing both equations

5 y + y = 24

y = 4

and x = 20

Therefore, Sharon is currently twenty years old, and her daughter is currently four years old.

[tex]y = -246[/tex] -- Her equivalent weight on earth

Step-by-step explanation:

Given

The attached table

Required

Fill in the gaps

(a) The equation

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

From the table, we can say that:

[tex](x_1,y_1) = (0,-300)[/tex]

[tex](x_2,y_2) = (300,0)[/tex]

So, we have:

[tex]m = \frac{0 -(-300)}{300 - 0}[/tex]

[tex]m = \frac{0 +300}{300}[/tex]

[tex]m = \frac{300}{300}[/tex]

[tex]m = 1[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - (-300) = 1(x - 0)[/tex]

[tex]y +300 = 1(x)[/tex]

[tex]y +300 = x[/tex]

[tex]y= x - 300[/tex]

(b) When x = 54

Substitute 54 for x in [tex]y= x - 300[/tex]

[tex]y = 54 - 300[/tex]

[tex]y = -246[/tex]

Answer:

4x+7=23

4.4+7=23

Step-by-step explanation:

23-7=16

16/4=4

The algebra tiles used in the equation 4x + 7 = 23 are four x-tiles, seven unit tiles, and 23 unit tiles.

To model the equation 4x + 7 = 23 using algebra tiles, we would use variable tiles (x-tiles) and unit tiles.

For the term 4x, we would use four x-tiles since the coefficient is 4.

For the term 7, we would use seven unit tiles since it is a constant.

The equal sign (=) does not have a specific tile representation; it simply indicates the equation's balance.

On the other side of the equation, for the term 23, we would represent it using 23 unit tiles.

So, the algebra tiles used in this equation would be four x-tiles, seven unit tiles, and 23 unit tiles.
