Given :

f(x) = (x-2)(x-4)

To find :-

The midpoint of x intercepts .

Answer :-

Given function :-

f(x) = (x-2)(x-4)

On equating with 0 ,

(x-2)(x-4) = 0 x = 2,4

Hence it cuts x axis on (2,0) and (4,0) .

Find the number of ordered pairs (m,n) which satisfy the system

4(m - n) &= 7(1 - n),
3/2n= 4-2m.

If there are infinitely many such pairs, enter the word infinite.

Answers

Answer:  0

There are no solutions to this system.

==========================================================

Explanation:

Let's simplify and rearrange terms for the first equation. The goal is to get it into the form Am+Bn = C, where A,B,C are constants.

4(m-n) = 7(1-n)

4m-4n = 7-7n

4m-4n+7n = 7

4m+3n = 7

Let's do the same for the second equation

(3/2)n = 4 - 2m

3n = 2(4-2m)

3n = 8 - 4m

4m+3n = 8

------------------------

The result of each simplification is that we ended up with 4m+3n on the left hand side for each equation. The only difference is that we got 7 for the first equation and 8 for the next one.

This is a contradiction because 4m+3n can only equal one number at a time for any given (m,n) pair. It's like saying z = 7 and z = 8 at the same time, where z = 4m+3n. But z can only equal one value at a time.

-------------------------

In summary, the given system leads to a contradiction and the system is inconsistent. This means that there are no solutions. There are 0 ordered pairs (m,n) that make both original equations to be true.

The correct answer is there is exactly one ordered pair ([tex]m = \dfrac{73}{56}[/tex] , [tex]n = \dfrac{13}{14}[/tex] ) that satisfies the given system of equations.

Given

[tex]4(m - n) = 7(1 - n)[/tex]

[tex]\dfrac{3}{2} n = 4 - 2m[/tex]

First, simplify the second equation:

[tex]\dfrac{3}{2} n +2m = 4[/tex]

Now,  solve this equation for n:

[tex]n = (4 - 2m) * \dfrac{2}{3}[/tex]

[tex]n = \dfrac{(8 - 4m)}{3}[/tex]

Now, substitute this value of n into the equation [tex]4(m - n) = 7(1 - n)[/tex] :

[tex]4(m - \dfrac{(8 - 4m)}{3}) = 7(1 - \dfrac{(8 - 4m)}{3}[/tex]

[tex]m = \dfrac{73}{56}[/tex]

From the value of m, substitute it back into the equation for n:

[tex]n = \dfrac{(8 - 4m)} { 3}[/tex]

[tex]n = \dfrac{13}{14}[/tex]

The solution is one ordered pair  [tex]m = \dfrac{73}{56}[/tex]  and  [tex]n = \dfrac{13}{14}[/tex].

Ben is a waiter at a restaurant. on Saturday, Ben got up at 6:30am, started work at X.am and finished work at X.pm. how long in hours did Ben work that Saturday​

Answers

Answer:

12 hours

Step-by-step explanation:

X = 6:30

From 6:30 am to 6:30 pm = 12 hr

The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.

The number of hours that Ben worked can be represented as:

= Time he finished working - Time he started working

= X pm - X am

If for instance, he started work at 7 am and finished at 12 pm, he would have worked:

= 12 - 7

= 5 hours

The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.

Answers

Answer:

30% decrease in price

Step-by-step explanation:

Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.

Explanation: turn 3 1/4 into an improper fraction makeing it 13/4 multiply both 7 and 2 by 2 makeing 7/2 into 14/4 add the two together 13/4+14/4= 27/4 then simplify down to 6 3/4

They cycled in total 6 3/4 miles.

What is mean by Fraction?

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

Padma cycles 3 1/4 miles.

And, Josh cycles 7/2 miles.

Now,

Since, Padma cycles 3 1/4 miles. Josh cycles 7/2 miles.

Hence, The total cycled by both = 3 1/4 + 7/2

                                                  = 13/4 + 7/2

                                                  = 13/4 + 14/4

                                                  = (13 + 14) / 4

                                                  = 27/4

                                                  = 6 3/4 miles

Thus, They cycled in total 6 3/4 miles.
