Answer:

x- intercept = 2, y- intercept = - [tex]\frac{8}{7}[/tex]

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x

4x - 7(0) = 8 , that is

4x = 8 ( divide both sides by 2 )

x = 2 ← x- intercept

To find the y- intercept , let x = 0 in the equation and solve for y

4(0) - 7y = 8, that is

- 7y = 8 ( divide both sides by - 7 )

y = - [tex]\frac{8}{7}[/tex] ← y- intercept

Answer: 13,12,5

Step-by-step explanation:

According to the triangles inequality : The sum of any two sides of a triangle must be greater than the third.

since [tex]6+5 =11 \ngtr 15[/tex]

[tex]20+10=30\ngtr40\\\\ 16+2=18\ngtr19[/tex]

Only pipe lengths with measure 13,12,5 can form triangle as

13+12 >5

12+5>13

13+5>12

Hence, the correct option is 13,12,5.

Answer:

I have the same questions and I got them right

Step-by-step explanation:

1.) P(2)=4/25

2.) P(4)= 5/25= 1/5

3.) P(2,3)=5/25= 1/5

4/25+1/25= 5/25= 1/5

4.) P(2,4,6)=16/25

4/25+ 5/25+ 7/25= 16/25

5.)There are three even numbers so, 3/6= 1/2. So, 1/2.

6.) P(1, 2, 3, 4, 5, 6)= 25/25 = 1

6/25+ 4/25+ 1/25+ 5/25+ 2/25+ 7/25= 25/25 = 1

P(1)= 6/25   P(2)= 4/25 P(3)= 1/25 P(4)= 5/25 P(5)= 2/25 P(6)= 7/25

Answer:

Step-by-step explanation:

1/3(12x+6x-21)

Take 1/3 of everything in the ()

4x+2x-7 combine like terms

6x-7

The equivalent expression is 6x - 7

Given the function 1/3(12x+6x-21), to get the equivalent expression, we will open the parenthesis using the distributive law;

= 1/3(12x+6x-21)

=  1/3(12x) + 1/3(6x) - 1/3(21)

= 4x + 2x - 7

On simplification, the resulting expression will be:

= 6x - 7

Hence the equivalent expression is 6x - 7

The amount she started with $20

Step-by-step explanation:

Let the amount Ahmya started with = x

when she bought $10 shirt, the remaining money is = x - 10

she spent half of this remaining money on dinner = [tex](\frac{x- 10}{2} )[/tex]

amount left after this = [tex](\frac{x- 10}{2} )[/tex]

she further spent $4 on cofee, the remaining money = [tex](\frac{x- 10}{2} )[/tex] - 4

she also spent 1/4 of remaining money on souveniers = [tex]\frac{1}{4}(\frac{x-10}{2} - 4)[/tex]

amount left = [tex]\frac{3}{4}(\frac{x-10}{2} - 4)[/tex]

The two last fractions should sum up to 1;

[tex]\frac{1}{4}(\frac{x-10}{2} - 4) + \frac{3}{4}(\frac{x-10}{2} - 4) = 1\\\\\frac{x-10}{8} -1 + \frac{3x-30}{8} -3= 1\\\\\frac{x-10}{8} + \frac{3x-30}{8} = 1+3+1\\\\\frac{x-10}{8} + \frac{3x-30}{8} = 5\\\\\frac{x-10 +3x-30}{8} = 5\\\\\frac{4x-40}{8} =5\\\\4x-40 =40\\\\4x =80\\\\x = 20[/tex]

x = $20

Therefore, the amount she started with $20

The rational root theorem is used to determine the potential roots of a function.

The potential roots are: [tex]\mathbf{-10, -5, 3, 15}[/tex]

The function is given as:

[tex]\mathbf{P(x) = x^3 + 6x^2 - 7x - 60}[/tex]

For a polynomial function:

[tex]\mathbf{P(x) = px^n +.............+ q}[/tex]

The potential roots are:

[tex]\mathbf{Roots = \pm \frac{Factors\ of\ q}{Factors\ of\ p}}[/tex]

The factors of 60 are:

[tex]\mathbf{60 = \pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}[/tex]

The factor of 1 is:

[tex]\mathbf{1 = \pm 1}[/tex]

So, we have:

[tex]\mathbf{Factors= \frac{\pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}{\pm 1}}[/tex]

[tex]\mathbf{Factors= \pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}[/tex]

The potential roots in the option are:

[tex]\mathbf{Factors= -10, -5, 3, 15}[/tex]

The change in kinetic energy of the car is -83439.06 joules.

The change in kinetic energy of an object is equal to the final kinetic energy minus the initial kinetic energy.

Since the car comes to rest after hitting the tree, its final kinetic energy is 0.

The initial kinetic energy of the car can be calculated using the formula KE = 1/2 m v², where KE is the kinetic energy, m is the mass of the object, and v is the velocity.

Plugging in the values, we get:

KE = 1/2 × 1622 kg × (11.3 m/s)²

KE = 1/2 × 1622 kg × 128.69 m²/s²

KE = 83439.06 kg m²/s²

To convert this value to joules, you can use the conversion factor 1 joule = 1 kg m²/s².

The change in kinetic energy of the car is equal to the final kinetic energy minus the initial kinetic energy, or 0 - 83439.06 kg m²/s² = -83439.06 kg m²/s².

Therefore, the car's kinetic energy dropped by -83439.06 joules.
