The inverse equation of x = y is y = x

<h3>What are inverse equations?</h3>

Inverse equations are the opposite of an original equation

<h3>How to determine the inverse equation?</h3>

The equation is given as

x = y

Swap the positions of x and y in the above equation

y = x

This means that the inverse equation of x = y is y = x

A company is selecting 6 people to be on a committee. There are 29 employees eligible to be on the committee. What is the total

postnew [5]

Answer: 342014400

Step-by-step explanation:

Given : A company is selecting 6 people to be on a committee.

Total employees eligible to be on the committee=29

Since each employee will have a different position on the committee, thus order matters here , so we use Permutations.

Number of permutation of n thing taking m things at a time is given by :-

$^nP_m=\dfrac{n!}{(n-m)!}$

Then, the number of permutation of 29 employees taking 6 at a time will be :-

$^{29}P_6=\dfrac{29!}{(29-6)!}\\\\=\dfrac{29\times28\times27\times26\times25\times24\times23!}{23!}\\\\=342014400$

Hence, the total number of ways the committee may be formed = 342014400

An exterior angle of an isosceles triangle has measure 150°. Find two possible sets of measures for the angles of the triangle.

nasty-shy [4]

<span>_Award brainliest if helped!
If the exterior angle of the bases is 150°, then the measure of the angle of each base is
30° and the measure of the vertex is 120°. If the exterior angle of the vertex is 150°, then the measure of the angle of each base is
75° and the measure of the vertex is 30°.</span>

If x=7+root 40 ,find the value of root x+1by the root of x

Luda [366]

Chapter : Algebra

Study : Math in Junior high school

x = 7 + √40

find √x of √x + 1

= √x + 1

= √(7+√40) + 1

in Formula is :

= √7+√40 = √x + √y

= (√7+√40)² = (√x + √y)²

= 7+√40 = x + 2√xy + y

= 7 + √40 = x + y + 2√xy

→ 7 = x + y → y = 7 - x ... Equation 1

→ √40 = 2√xy → √40 = 2.2√10 = 4√10

= xy = 10 ... Equation 2

substitution Equation 1 to 2 :

= xy = 10

= x(7-x) = 10

= 7x - x² = 10

= x² - 7x + 10 = 0

= (x - 5)(x - 2) = 0

= x = 5 or x = 2

Subsitution x = 5 and x = 2, to equation 1

#For x = 5

= y = 7 - x

= y = 7 - (5)

= y = 2

#For x = 2

= y = 7 - x

= y = 7 - (2)

= y = 5

and his x and y was find :

#Equation 1 :

= x = 5 and y = 2

#Equation 2 :

= x = 2 and y = 5

So that :

√7+√40 = √x + √y

= √7+√40 = √2 + √5

And that is answer of question :

= √2 + √5 + 1

I don't get any thing about adding subtraction dividing or multiply fractions

svp [43]

Answer:

its easy

Step-by-step explanation:

for example for addition,

15+4/5

=here we will take the LCM of 1 and 5

LCM=5

to make the denominator 5 we should divide

15/1+4/5

=75/5+4/5

=79/5

for division,

3/2÷5/4

just wright the reciprocal of 5/4

=3/2×4/5

here no need to find LCM, u can just multiply the no. just next to it

=12/10 is the ans

Questions regarding the time spent by Jack jogging and bike riding are needed to be answered.

(A) The equations are $x+y=75, y=15+x$

Time spent jogging is 30 minutes

The total time would be $45+60=105$ minutes which is not equal to 75 minutes.

(B) Let $x$ be the time spent jogging.

$y$ be the time spent bike riding.

$x+y=75\\y=15+x\\x+15+x=75\\2x+15=75\\x=\frac{75-15}{2} =30$

Time spent jogging is 30 minutes.

$y=60\\x+y=75$

Therefore, the total time would be $45+60=105$ minutes which is not equal to 75 minutes.
