The difference of two integers is thirty. the larger integer is two more than five times the smaller integer. Find the integers
Mnenie [13.5K]
X=2+5y
x-y=30

basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.

this is the new equation : x=30+y

now i plug this equation into the first one.

30+y=2+5y

30=2+5y-y
30=2+4y
28=4y
y=7

now that you know what y is, take that second equation we did in the beginning and plug in y.

x-7=30

solve for x

x=37



the two integers are 37 and 7.

Given the similar triangles below find the missing length
lilavasa [31]

Answer:

SB or ? = 9

Since the two triangles are similar.

((18 + 6) / 6) = 24 / 6 = <u>4</u>

[Scale factor between ∆BCU and ∆SUT]

SB or ? = 12 – 12/<u>4</u> = 12 – 3 = 9

Find f(x) if it is known that f(x−6)=12x−72.
zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation  

This means that if you take out -6 from the x

You will get f(x)=12x

(Also do you go to RSM?)
