Step-by-step explanation:

or,(x-2)(x-4)+(3x-11)(x-3)/(x-3)(x-4)=(4x+13)/(x+1)

or,x^2-4x-2x+8+3x^2-9x-11x+33/x^2-4x-3x+12=(4x+13)/(x+1)

or,4x^2-4x-2x-9x-11x+8+33/x^2-7x+12=(4x+13)/(x+1)

or,4x^2-26x+41/x^2-7x+12=(4x+13)/(x+1)

or, (x+1)(4x^2-26x+41)=(4x+13)(x^2-7x+12)

or,4x^3-26x^2+41x+4x^2-26x+41=4x^3-28x^2+48x+13x^2-91x+156

or,-26x^2+4x^2+28x^2-13x^2+41x-26x-48x+91x=156-41

or,-7x^2+58x=115

or,-7x^2+58x-115=0

or,-(7x^2-58x+115)=0

or,7x^2-58x+115=0

or,7x^2-(35+23)x+115=0

or,7x^2-35x-23x+115=0

or,7x (x-5)-23 (x-5)=0

or, (x-5)(7x-23)=0

Either, Or,

(x-5)=0 (7x-23)=0

or,x=0+5 or,7x=23

:x=5 :x=23/7

Hence,x=5 or 23/7

Answer:

The maximum height of the rocket is 64 ft.

Step-by-step explanation:

The -t^2 term tells us that the graph of this function is a parabola that opens down.  The x-coordinate of the axis of symmetry is

        -b

x = -----------

       2a

which here is:

        -32

x = ------------ = 1

       2(-16)

The value of this function at t = 1 is

h(1) = -16(1)^2 + 32(1) + 48, or 64 ft

The maximum height of the rocket is 64 ft.

Answer:

  y = 7

Step-by-step explanation:

The slope is ...

  m = (7 -7)/(0 -4) = 0

The y-intercept is the point (0, 7), so the slope-intercept equation is ...

  y = mx +b

  y = 0·x +7

Simplifying this puts it in standard form:

  y = 7

Answer:

The answer is (1,4) because both lines pass through this point.

Step-by-step explanation:

To find a solution to a system of equations, both lines have to pass through the same point. If both lines intercept at the same point, that means that point is the solution to the system of equations.

Answer:

x = 20 , ∠ A = 125°

Step-by-step explanation:

∠ A and ∠ B are alternate angles and are congruent, then

6x + 5 = 4x + 45 ( subtract 4x from both sides )

2x + 5 = 45 ( subtract 5 from both sides )

2x = 40 ( divide both sides by 2 )

x = 20

Then

∠ A = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°

Answer: 238

Step-by-step explanation:

The formula to calculate the nth term of an arithmetic progression = a + (n-1)d

Based on the question,

a = -140

90th term = a + 89d = 483

We need to get the value of the common difference

a + 89d = 483

-140 + 89d = 483

89d = 483 + 140

89d = 623

d = 623/89

d = 7

Therefore 55term will be:

= a + (n - 1)d

= a + (55 - 1)d

= a + 54d

= -140 + 54(7)

= -140 + 378

= 238

Option 3

Step-by-step explanation:

The sentence provides the reasoning for a possible explanation.

Now, let's look at all the possible answers:

1. This doesn't show us that scientists cannot agree. A sentence like that could be that many scientists have analyzed the region, but they did not find anything.

2. This does not tell us that this region is interesting. A sentence like that would be saying that the cause of the lightning is unknown.

3. This is correct- it provides evidence for a main theory.

4. This does not explain why people name the lightning a certain way. A sentence like that could be a local fable.

Answer:

1.25 hours

Step-by-step explanation:

Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?

The number of hours he spent riding and walking to his friends house is calculated as:

45 minutes + 30 minutes

= 75 minutes

Converting this to hours

60 minutes = 1 hour

75 minutes = x

Cross Multiply

60 × x = 75 × 1

x = 75/60

x = 1.25 hours

Answer:

The hypothesis formulae will be

H0 : p = 0.5

Ha : p < 0.5

we will reject H0.

Step-by-step explanation:

Number of responses ( n ) = 1017

percentage( p ) = 39% = 0.39

significance level ( ∝ ) = 0.05

P0 = 50% = 0.5

Test the claim that fewer than half of all teenagers feel the pressure

The hypothesis formulae will be

H0 : p = 0.5

Ha : p < 0.5

Perform the test statistic

Test statistic ( Z ) = -6.957

P-value < 0.05   we will reject H0.  

Answer:

y=-2x+1

Step-by-step explanation:

to find the slope use the formula (y2-y1)/(x2-x1)
