Describe how to solve 4x = 36.

netineya [11]

Answer:

hope this helps! :)

Step-by-step explanation:

4x=36

divide both sides of the equation by 4

4x / 4 = 36 / 4

Any expression divided by itself equals 1

x= 36 / 4

Calculate the quotient

36/4 = 9

<u>x=9</u>

Explain how the graph of y=|x+1|-2 will differ from the graph of y=|x|.

Natali5045456 [20]

$\bf ~~~~~~~~~~~~\textit{function transformations}\\\\\\f(x)= A( Bx+ C)+ D\\\\~~~~y= A( Bx+ C)+ D\\\\f(x)= A\sqrt{ Bx+ C}+ D\\\\f(x)= A(\mathbb{R})^{ Bx+ C}+ D\\\\f(x)= A sin\left( B x+ C \right)+ D\\\\--------------------\\\\\bullet \textit{ stretches or shrinks horizontally by } A\cdot B\\\\\bullet \textit{ flips it upside-down if } A\textit{ is negative}$

$\bf ~~~~~~\textit{reflection over the x-axis}\\\\\bullet \textit{ flips it sideways if } B\textit{ is negative}\\~~~~~~\textit{reflection over the y-axis}\\\\\bullet \textit{ horizontal shift by }\frac{ C}{ B}\\~~~~~~if\ \frac{ C}{ B}\textit{ is negative, to the right}$

$\bf ~~~~~~if\ \frac{ C}{ B}\textit{ is positive, to the left}\\\\\bullet \textit{ vertical shift by } D\\~~~~~~if\ D\textit{ is negative, downwards}\\\\~~~~~~if\ D\textit{ is positive, upwards}\\\\\bullet \textit{ period of }\frac{2\pi }{ B}$

with that template in mind,

$\bf y=\stackrel{A}{1}|\stackrel{B}{1}x\stackrel{C}{+1}|\stackrel{D}{-2}$

so is really just |x| but shifted some,

C/B = 1/1 = +1, horizontally to the right by 1 unit.

D = -2, vertically downwards by 2 units.

Hendrick wants to enlarge a photo that is 4 inches wide and 6 inches tall. The enlarged photo keeps the same ratio. How y'all is

zhuklara [117]

Answer:

Step-by-step explanation:

Alright, lets get started.

The original photo size is 4 inches wide and 6 inches tall.

So, the ratio of width and height will be = $\frac{4}{6}=\frac{2}{3}$

The new enlarged photo will be of the same ratio means 2:3

The width of enlarged photo is given as 12 inches.

Suppose new height of enlarged photo is H, so

$\frac{12}{H}=\frac{2}{3}$

Cross multiplying

$2H=36$

Dividing 2 in both sides

$H=18$ inches

So the height of new enlagred photo will be 18 inches. : Answer

Hope it will help :)

A garden is in the shape of a square of length 35 2/5 m. find its (i) perimeter and (ii) area.

Crank

Answer:

perimeter = 56 m

area= 196 m^2

Step-by-step explanation:

perimeter = 4 x sides = 4 x 35(2/5) = 4 x 14 = 56 m

area= sides^2 = (35 x $\frac{2}{5} )^{2}$ = 14^2 = 196 m^2

I don't understand raitos please help solve math problems

ollegr [7]

1st is to make the numbers into ratios. Basically taking the two numbers and putting them in the middle. I’ll do the 1st 15:36.
Next you put it into a fraction: 15/36
Put in the comments if you want me to do all or if you have any questions!
