Anyone know the answer to this please?

Step-by-step explanation:

Let H = HCF(A,B) and L = LCM(A,B)

Then A*B = L*H

Here L*H = 100*5 = 500

Also H <= A ,B <= L

So we need to find all A*B = 500, satisfying the above condition. This can be done using prime factorisation of 500.

Here 500 = 2^2 * 5^3

so possible values of A and B are

1 , 500

2, 250

4, 125

5,100

10,50

20,25

(assuming order doesn’t matter.)

so pairs satisfying given condition are → (20,25) and (100,5)

You can write a computer program in language of your choice to do it for other bigger numbers.

Answer:

When you solve for y, you get y = 20.

Step-by-step explanation:

You isolate the variable by dividing each side of the equation by the number with the variable, therefore getting 20.

Step-by-step explanation:

Given:

The linear equation is:

[tex]y+6=-\dfrac{5}{2}(x+4)[/tex]

To find:

The general form of the given linear equation.

Solution:

The general form of a line is equation is:

[tex]Ax+By=C[/tex]

We have,

[tex]y+6=-\dfrac{5}{2}(x+4)[/tex]

Multiply both sides by 2.

[tex]2(y+6)=-5(x+4)[/tex]

[tex]2(y)+2(6)=-5(x)-5(4)[/tex]

[tex]2y+12=-5x-20[/tex]

Isolating variable terms, we get

[tex]2y+5x=-20-12[/tex]

[tex]5x+2y=-32[/tex]

Therefore, the general form of the given linear equation is [tex]5x+2y=-32[/tex].

Step-by-step explanation:

x = -3

Step-by-step explanation:

This is a vertical line.  The x value remains constant.

Answer:

x= 5.45 or -5.45

Step-by-step explanation:

Given:

Depart 2:30 pm PST

Arrive 7:20 pm CST

To find:

The total travel time

Solution:

We know that time in CST is 2 hours more than the time in PST

Depart time = 2:30 pm PST

Convert this time in CST.

Depart time = (2:30+2:00) pm CST

                    = 4:30 pm CST

We have,

Arrive time = 7:20 pm CST

The total travel time is the difference between 7:20 pm CST and 4:30 pm CST.

7:20 pm - 4:30 pm = 2 hr 50 min

The total travel time is 2 hr 50 min.

Therefore, the correct option is D.

Answer:

y = - 3

Step-by-step explanation:

x = 4 is a vertical line parallel to the y- axis

A line perpendicular to it will be a horizontal line parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates of the points the line passes through.

The line passes through (- 3, - 3) with y- coordinate - 3 , then

y = - 3 ← equation of perpendicular line

Step-by-step explanation:

Step 1: Define Systems

y = 4x - 18

y = -5x + 9

Step 2: Solve for x

Substitution

Step 3: Solve for y

Answer:

x=3

y = -6

Step-by-step explanation:

y = 4x – 18

y = -5x +9

Set the two equations equal

4x – 18 = -5x +9

Add 5x to each side

4x – 18 +5x= -5x+5x +9

9x -18 = 9

Add 18 to each side

9x -18 +18 = 9+18

9x =27

Divide by 8

9x/9 = 27/9

x = 3

Now find y

y = 4x-18

y = 4*3 -18

y =12-18

y = -6

Answer:

11.3 cm

Step-by-step explanation:

since this is an equilateral triangle it's every sides are equal

side length (a) = 13 cm

formula to calculate the height of equilateral triangle is

h = [tex]a *\frac{\sqrt{3} }{2}[/tex]

=[tex]13 * \frac{\sqrt{3} }{2}[/tex]

=[tex]\frac{13\sqrt{3} }{2}[/tex]

=11.25

=11.3

Answer:

Step-by-step explanation:

If A is parallel to B, then angles 2 and 4 are same side interior and they are supplementary. Thus,

2x + 10 + 4x + 80 = 180 and

6x = 90 so

x = 15

Answer:

Answer is B.

Step-by-step explanation:

You can solve this by recognizing the vertex and the y-intercept of the quadratic equation based on the information provided.

The vertex occurs 6 seconds into the jump, when the cord is fully stretched to 72m, before it starts to contract again. This is when the jumper is closest to the ground, 122-72 = 50m above the ground. Notice the jumper never reaches the ground because the cord is only 72m long - it can't make it the full 122m - so there will not be an x-intercept (or t-intercept in this case). Anyway - the vertex is (6,50) using this information.

The y-intercept is the point at which t=0, the beginning of the jump. At the beginning of the jump, the jump is still on top of the cliff, 122m up. So the coordinates of the y-intercept are (0,122).

Now plug these values into the vertex form of the quadratic formula and solve for a:

[tex]f(t) = a(t-h)^2+k\\122=a(0-6)^2+50\\72 = 36a\\a=2[/tex]

This means our general equation (in vertex form) for this scenario is:

[tex]f(t)=2(t-6)^2+50[/tex]

Our answer options are in standard form, so just expand the vertex form of the equation to finish:

[tex]f(t)=2(t-6)^2+50\\f(t)=2(t^2-12t+36)+50\\f(t)=2t^2-24t+72+50\\f(t)=2t^2-24t+122[/tex]

First solution :

Say, x = 0

→ 2x + 3y = 4

→ 2(0) + 3y = 4

→ 0 + 3y = 4

→ 3y = 4

→ y = 4/3

Second solution :

Say, x = 1

→ 2x + 3y = 4

→ 2(1) + 3y = 4

→ 2 + 3y = 4

→ 3y = 4 - 2

→ 3y = 2

→ y = 2/3

Third solution :

Say, x = 2

→ 2x + 3y = 4

→ 2(2) + 3y = 4

→ 4 + 3y = 4

→ 3y = 4 - 4

→ 3y = 0

→ y = 0 ÷ 3

→ y = 0

⇒ 1600 ≠ 1689

Answer:

EQUATION:  24 + 3X = 27. INEQUALITY: 2X - 6 < 18.

Step-by-step explanation:

For the equation:

"A number" means that we do not know what the number is yet. So it is a variable. I chose the variable, "X."

"The SUM of 24 AND" means we are adding 24 to something. So what we have so far is "24 + ..."

"3 times a number" means we are multiplying 3 by the unknown variable X. So 3X. What we have so far is "24 + 3X..."

"is 57" means that everything we've just stated equals 57.

Our entire equation is: 24 + 3x = 27.

For the inequality:

Inequalities mean that two expressions are NOT equal to each other.

"6 less than" means that we subtract 6. So we have,"6 - ..." so far.

"Double a number" means 2 times a number, which we are saying is X. So "2X."

" is less than 18" means that everything we just said is less than the value of 18.

So the whole inequality is: 2X - 6 < 18.
