Answer 1

Answer:

x=2

Step-by-step explanation: 1.2x-5.2=-2.4x+2. First, you add 2.4x to 1.2x to get x isolated. So now it's 3.6x-5.2=2. Then add 5.2 to 2 to isolate x. Now you have 3.6x=7.2 now you divide 7.2 by 3.6 to get x=2.

Answer 2

Answer:

x=2

Step-by-step explanation:

1.2x-5.2=-2.4x+2

multiply 10

12x-52=-24x+20

refine and add 52

12x=-24x+72

add 24x

36x=72

divide 36

x=2

Florian ran 1. 2 miles and walked 4. 8 laps around the path at the park for a total distance of 3. 6 miles. Which shows the correct equation and value of x, the distance of 1 lap around the path at the park? 3. 6 x 1. 2 = 4. 8; x = 1 mile 4. 8 x 1. 2 = 3. 6; x = 1 mile 3. 6 x 1. 2 = 4. 8; x = 0. 5 mile 4. 8 x 1. 2 = 3. 6; x = 0. 5 mile.

Answers

The correct equation and value of x, the distance of 1 lap around the path at the park is 4.8x + 1.2 = 3.6. Then the correct option is B.

What is the linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Florian ran 1.2 miles and walked 4.8 laps around the path at the park for a total distance of 3.6 miles.

This is because lap will be dependent on the variable, we know that the number of them will be multiplied by the variable x we also know that 1.2 miles are constant. Now the equation will be

4.8x + 1.2 = 3.6

Thus, the correct option is B .

Answers

Answer:

what do I do I’m new

Step-by-step explanation:

Answer:

y=9 and x=15

Step-by-step explanation:

ok looking at what they give us in the question we can see that we have two equations. to solve for it be will need to combine them together

note that because they use the word sum we know it's addition

y= x-6

x+y=24

now that we have these we can substitute y=x-6 for the y in our addition equaution such that we have it in terms of one variable:

x+ (x-6) = 24

2x-6=24

2x=30

x=15

now going back we can find Y

15+ y = 24

y=9

In a recursive function, what is used to determine whether to stop or to continue with another recursive step

Answers

Recursive functions are functions whose execution is called from within itself

A condition is used to stop or continue another recursive step

When does a recursive function stop?

As implied earlier, the execution of a recursive function is from within the function itself.

This means that the recursive function will continue its execution, until a condition is met.

This condition is used to determine the execution or the termination of the recursive process

Hence, a condition is used to stop or continue another recursive step

Circles (represented by their equations in general form) in ascending order of their radius lengths can be arranged as first-fifth-second-forth-third-seventh-sixth.

What is the equation of circle?

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here (h,k) is the center of the circle and (r) is the radius of the circle.

Lets arrange the first equation, in standard form of equation of circle as,

[tex]x^2 +y^2 - 2x+ 2y -1 = 0 \\(x^2 - 2x) +(y^2+ 2y )= 1\\(x^2 - 2x+1) +(y^2+ 2y +1)= 1+1+1\\(x-1)^2+(y+1)^2=(\sqrt{3})^2[/tex]

The radius of this circle is √(3).

Lets arrange the second equation, in standard form of equation of circle as,

[tex]x^2 +y^2 - 4x+ 4y - 10 = 0 \\(x^2 - 4x) +(y^2+ 4y )= 10\\(x^2 - 4x+4) +(y^2+ 4y +4)= 10+4+4\\(x-2)^2+(y+2)^2=(\sqrt{18})^2[/tex]

The radius of this circle is √(18).

Lets arrange the third equation, in standard form of equation of circle as,

[tex]x^2 +y^2 - 8x - 6y - 20 = 0 \\(x^2 - 8x) +(y^2-6y )= 20\\(x^2 - 8x+16) +(y^2- 6y +9)= 10+16+9\\(x-4)^2+(y-3)^2=(\sqrt{45})^2[/tex]

The radius of this circle is √(45).

Similarly, radius of the forth, fifth, sixth and seventh circle is √(23), √(5), √(117) and √(46) units.

Hence, the circles (represented by their equations in general form) in ascending order of their radius lengths can be arranged as first-fifth-second-forth-third-seventh-sixth.

Are 7/-8 and -7/8 equal?​

Answers

Yes, they are

Because with fractions, you can divide. The rules for multiplying or dividing with negative numbers are that negative * or / negative = positive and that one negative * or / a positive = negative. These fractions here have one negative and one positive, making it so that when you divide, it will be negative.

Hello.

[tex]\mathrm{\displaystyle\frac{7}{-8} \:and\:\frac{-7}{8} \:are\:equal\:}[/tex]

If we divide a positive number by a negative number, we get a negative number.

Let's try.

We can turn both of these fractions into decimals and see if they are equivalent.

The simplest way to turn a fraction into a decimal is divide the numerator by the denominator.

[tex]\mathrm{\displaystyle\frac{7}{-8} = -0.875}[/tex]

Now, let's convert the second fraction into a decimal:

[tex]\mathrm{\displaystyle\frac{-7}{8} =-0.875}[/tex]

[tex]\mathrm{-0.875=-0.875}[/tex]

Therefore, the two fractions are equivalent (equal).

I hope it helps.

Answer for 50 BRAINLIST!!!

Answers

Answer:

[tex](2, 4)\rightarrow\text{First system}[/tex]

[tex](4, -2)\rightarrow\text{Second system}[/tex]

Step-by-step explanation:

First system:

We can substitute 2x for y:

[tex]6x-y=8\\6x-2x=8\\4x=8[/tex]

Divide both sides by 4

[tex]x=2[/tex]

Substitute 2 for x to solve for y:

[tex]y=2x=2(2)=4[/tex]

[tex](x, y)=(2, 4)[/tex]

Second system:

We can isolate x in the second equation by subtracting 4y from both sides:

[tex]x=-4-4y[/tex]

Now, substitute this value for x in the first equation:

[tex]3(-4-4y)+5y=2\\[/tex]


Distribute the 3 to each term in the parentheses:

[tex]3(-4)+3(-4y)+5y=2\\-12-12y+5y=2\\-12-7y=2[/tex]

Add 12 to both sides:

[tex]-7y=14[/tex]

Divide both sides by -7

[tex]y=-2[/tex]

Now, substitute -2 for y to solve for x:

[tex]x=-4-4y=-4-4(-2)=-4+8=4[/tex]

[tex](x, y)=(4, -2)[/tex]

Solve the system by substitution.
y = -5x - 40

Step-by-step explanation:

Shadow problems almost always involve similar triangles, meaning that shadow lengths and object heights generally have the same ratio. We can use this fact to write proportions related to the measures in this problem.

(i)

The ratio of shadow-tip distance to the object height is the same for both objects. For distances in meters, we have ...

  x/7 = (x-y)/2

  2x = 7(x -y) . . . . . multiply by 14

  7y = 5x . . . . . . . add 7y-2x

  y = 5/7x . . . . . divide by the coefficient of y

__

(ii)

Solving the equation from the first part for x, we have ...

  x = 7/5y . . . . . multiply by 7/5

The derivative with respect to time is then ...

  x' = 7/5y'

The rate of change of y is given as 5/3 m/s, so the rate of change of x will be ...

  x' = (7/5)(5/3 m/s) = 7/3 m/s
