the important thing you need to know in solving mathematics is to understand the question and the formulae that follws.for finding equations ur general formulae us:

y-y1=m(x-x1)

do not solve y and x.

the y1 and x1 are ur x and y values from ur coordinates respectively.

m is ur gradient or slope given.

plug in the values.

Step-by-step explanation:

y-y1=m(x-x1)

y-4=2/5(x-(-2))

the x-(-2) will change to positive thus giving you an equation of:

y-4=2/5(x+2).

Using opposite by the same vertex and supplementary angles, it is found that the measure of angle 4 is of 66º.

In this problem, angles 5 and 7 are opposite by the same vertex, hence:

m<7 = m<5 = 114º.

Angles 4 and 5 are supplementary, hence:

m<4 + m<5 = 180º.

m<4 = 66º.

The measure of angle 4 is of 66º.

Answer:

b=19.25

Step-by-step explanation:

Ok, so if you plug in 77 for A and 4 for h, you will get 77=4h. So from here, you have to divide 77 by 4, which is 19.25 and that is the answer for variable b.

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

Answer:

Choice C

Step-by-step explanation:

We are given the function:

[tex]\displaystyle \large{f(x)=3x+5}[/tex]

Let [tex]\displaystyle \large{y=f(x)}[/tex] therefore:

[tex]\displaystyle \large{y=3x+5}[/tex]

To find an inverse of function, swap the position of x and y:

[tex]\displaystyle \large{x=3y+5}[/tex]

Then solve or simplify the equation in term of y:

[tex]\displaystyle \large{x-5=3y}\\\displaystyle \large{\frac{x-5}{3}=y}\\\displaystyle \large{y=\frac{1}{3}x-\frac{5}{3}}[/tex]

Therefore, the answer is choice C.

__________________________________________________________

Summary

An inverse function is a function that swaps the position of domain and range, defined as notation [tex]\displaystyle \large{f^{-1}(x)}[/tex] or [tex]\displaystyle \large{y^{-1}}[/tex] generally. When finding an inverse function, make sure to swap position of range and domain, if given the interval.

Only one-to-one functions may have an inverse — multiple-to-one can not have an inverse such as quadratic function or any even-degree polynomial functions.

The average speed is the ratio of the total distance to the total time. Then the average distance covered in one hour​ by the bus is 60 kilometers.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distace }{Time }[/tex]

A bus traveled 63 km in the first hour 60 km in the second hour and 57 km in the third hour.

Then the average speed will be

[tex]\rm Average \ speed = \dfrac{Total \ distace }{Total \ time }\\\\\\Average \ speed = \dfrac{63 + 60 +57}{1+1+1}\\\\\\ Average \ speed = \dfrac{180}{3}\\\\Average \ speed = 60 \ km/h[/tex]

The average distance covered in one hour​ by the bus is 60 kilometers.

Answer:

Step-by-step explanation:

Answer: x = $7, y = $6

Step-by-step explanation:

Let x be the cost of an adult ticket

Let y be the cost of a children's ticket

Translate these sentences to algebra:

At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51

Five adult tickets and two child tickets cost $47: 5x + 2y = 47

Now we have two equations. Let's use substitution to solve.

3x + 5y = 51

3x = 51 - 5y

.: x = 17 - 5y/3

Now substitute this value of x into the second equation to find the numerical value of y:

5(17 - 5y/3) + 2y = 47

85 - 25y/3 + 2y = 47

-19y/3 = -38

-19y = -114

.: y = 6

Now find x:

x = 17 - 5y/3

x = 17 - 10

.: x = 7

So an adult ticket costs $7, and a child ticket costs $6 :)

Answer:

20

Step-by-step explanation

use the formula a²+b²=c²

since a=21 and c=29 you need to solve for b

Put 21 in for a and 29 in for c

21²+b²=29²

21²=441

29²=841

so then the equation would be 441+b²=841

subtract both sides by 441

then you have b²=400

now just find the square root of 400

√b²=√400

b=20
