Explain or show that the point (5,-4) is a solution to this system of equation 3x-2y=23

Answers

Answer 1

Answer:

Step-by-step explanation:

3(5)-2(-4)=23

15+8=23

23=23

Answer 2

The system of equation 3x-2y=23 satisfies the point (5, -4) after plugging x = 5 and y = -4, the point is a solution to the equation.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation of linear equation is:

3x - 2y = 23

The point is (5, -4)

Plug x = 5 and y = -4

3(5) - 2(-4)  = 23

15 + 8 = 23

Thus, the system of equation 3x-2y=23 satisfies the point (5, -4) after plugging x = 5 and y = -4, the point is a solution to the equation.

Formula:

Height:

Answers

Answer:

Formula:  V = 1/3πr^2h

Height: 6cm

Step-by-step explanation:

step one:

given information

volume =32π cm^#

radius=4cm

step two:

The formula is

V = 1/3πr^2h

substituting we have

32π =1/3π*4^2*h

32π=16πh/3

π cancels out

step three:

cross multiply we have

32*3=16h

divide both sides by 16 we have

96/16=h

h=6cm

Answers

Complete Question

The  relationship  between  altitude  and  the  boiling  point  is  linear. At  an  altitude  of   8300ft, the  liquid  boils  at   194.23 °  F

At  an  altitude  of   4200 ft ,  the  liquid  boils  at   202.02° F.

Write  an  equation  giving  the  boiling  point   b  of  the  liquid,  in  terms  of  altitude  a  in   feet . feet . What  is  the  boiling  point  of  the  liquid  at   2600ft

Answer:

The equation is  [tex]y  =  -0.001943x + 210.3569 [/tex]

At  2600ft  the temperature is  [tex]y  =  205.3051 \  °F [/tex]

Step-by-step explanation:

From the question we are told that

    The temperature at 8300ft is 194.23 °  F

    The  temperature at 4200 ft is 202.02° F

Generally the slope for this relationship is mathematically represented as

      [tex]m  =  \frac{ 202.2 - 194.23}{ 4200 - 8300}[/tex]

=>     [tex]m  = 0.001943  ^o  F / ft [/tex]  

Generally the according to the point slope formula is

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

=>   [tex]y - 194.23 =  -0.001943 (x - 8300 )[/tex]

=>  [tex]y - 194.23 =  -0.001943x + 16.1269 [/tex]

=>  [tex]y  =  -0.001943x + 210.3569 [/tex]

Now we are given from the question that   x =  2600 ft

Then  

         [tex]y  =  -0.001943(2600) + 210.3569 [/tex]

=>      [tex]y  =  205.3051 \  °F [/tex]

Step-by-step explanation:

A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says they now have about 120 apples. Is the owner's estimate reasonable? The owner's answer is reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 fewer apples than they started with. The owner's estimate is not reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 more apples than they started with. The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with. The owner's estimate is not reasonable. They ordered about 240 apples and sold about 240 so they should have about the same number of apples as they started with.

Answers

Answer:

The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.

Step-by-step explanation:

Given that:

Number of apples already available with Owner = 200

Number of bags of apples ordered with 12 apples each = 19

Number of apples ordered = 12 [tex]\times[/tex] 19 = 228

OR

Rounding off 19 to 20:

Number of apples ordered  = 12 [tex]\times[/tex] 20 = 240

Around 240 apples were ordered.

Number of bags of apples with 8 apples each, sold = 42

Number of apples sold = 42 [tex]\times[/tex] 8 = 336

Rounding off 42 to 40, number of apples sold = around 320

Therefore, 80 more apples were sold than that of apples bought.

So, according to the estimate, there will be 80 fewer apples left than they started with.

Correct answer is:

The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with

Answer:

x = -9

Step-by-step explanation:

To solve the equation

Simplify each sideSeparate the variable on one side and the numerical term on the other sideMake the coefficient of the variable equal 1

Let us do these steps with our question to find x

∵ 4(2x + 7) = 12 - 2(10 - 2x)

→ Simplify each side

∵ 4(2x) + 4(7) = 12 - 2(10) - 2(-2x)

8x + 28 = 12 - 20 + 4x

→ Add the like terms in the right side

∵ 8x + 28 = (12 - 20) + 4x

8x + 28 = -8 + 4x

→ Subtract 28 from both sides

∵ 8x + 28 - 28 = -8 - 28 + 4x

8x = -36 + 4x

→ Subtract 4x from both sides

∵ 8x - 4x = -36 + 4x - 4x

4x = -36

→ Make coefficient of x equal 1 by dividing both sides by 4

∴ [tex]\frac{4x}{4}=\frac{-36}{4}[/tex]

x = -9

The sum of 5 amd 8 terms of an A.P is 37 and its 11 term is 32 find the A.P

Answers

Given:

Sum of 5th & 8th terms of an AP = 37

11th term = 32

Find:

A.P

Solution:

We know that,

nth term of an AP – an = a + (n - 1)d

Hence,

⟹ a₅ + a₈ = 37

⟹ a + (5 - 1)d + a + (8 - 1)d = 37

⟹ 2a + 4d + 7d = 37

⟹ 2a + 11d = 37 -- equation (1)

Similarly,

⟹ a₁₁ = 32

⟹ a + (11 - 1)d = 32

⟹ a + 10d = 32

⟹ a = 32 - 10d

Substitute the value of a in equation (1).

⟹ 2(32 - 10d) + 11d = 37

⟹ 64 - 20d + 11d = 37

⟹ 64 - 37 = 20d - 11d

⟹ 27 = 9d

⟹ 27/9 = d

⟹ 3 = d

Substitute the value of d in equation (1).

⟹ 2a + 11(3) = 37

⟹ 2a + 33 = 37

⟹ 2a = 37 - 33

⟹ 2a = 4

⟹ a = 4/2

⟹ a = 2

Now,

General form of an ap = a , a + d , a + 2d...

⟶ Required AP = 2 , 2 + 3 , 2 + 2(3)...

⟶ Required AP = 2 , 5 , 2 + 6...

⟶ Required AP = 2 , 5 , 8...

I hope it will help you.

Regards.

Answer:

→ md - 2nd + 3md = 2 * [ a + (n - 1)d ]

→ 4md - 2nd = 2 * [ a + (n - 1)d ]

→ 2(2md - nd) = 2 * (a + nd - d)

→ 2md - nd - a + d = nd

→ 2md - nd - (md - 2nd) + d = nd

[ From equation (1) ]

→ 2md - nd - md + 2nd + d = nd

→ md + nd + d = nd

→ (m + n + 1)d = n * d

→ (m + n + 1) = n
