Answer:

f(n) = 3+3(n-3)

Step-by-step explanation:

We can first notice that the slope is 3 and a y intercept of 0. So, we can just simplify all the equations

f(n) = 4+3(n-1)

f(n) = 4+3n-3

f(n) = 3n+1

y=3x+1

No

f(n) = 3+5(n-1)

f(n) = 3+5n-5

y=5x-2

No

f(n) = 2+3(n-1)

f(n) = 2+3n-3

y=3x-1

No

f(n) = 3+3(n-1)

f(n) = 3+3n-3

Yes

y=3x

Question: "If y > 3, what is the value of n ?"
iris [78.8K]

Answer:

y-3

Problem:

What is the remainder when the dividend is xy-3, the divisor is y, and the quotient is x-1. ?

Step-by-step explanation:

Dividend=quotient×divisor+remainder

So we have

xy-3=(x-1)×(y)+remainder

xy-3=(xy-y)+remainder *distributive property

Now we just need to figure out what polynomial goes in for the remainder so this will be a true identity.

We need to get rid of minus y so we need plus y in the remainder.

We also need minus 3 in the remainder.

So the remainder is y-3.

Let's try it out:

xy-3=(xy-y)+remainder

xy-3=(xy-y)+(y-3)

xy-3=xy-3 is what we wanted so we are done here.

What is 5 minus 7/16
nekit [7.7K]
Hello.

Convert.
5 = 80/16
80/16 - 7/16 = 73/16
Simplify.
73/16 = 4  \frac{9}{16}
Thus, 5 - 7/16 = 4  \frac{9}{16}
You're welcome.

This was given to me during a summative test and the teacher didn't bother giving me the correction. I just cannot figure it out

  • Base be y

ATQ

\\ \sf\longmapsto xy=6050\dots 1

\\ \sf\longmapsto 2(x+y)=220\implies x+y=110\dots 2

Now

\\ \sf\longmapsto (x+y)^2=x^2+y^2+2xy

\\ \sf\longmapsto 110^2-2(6050)=x^2+y^2

\\ \sf\longmapsto 12100-12100=x^2+y^2

\\ \sf\longmapsto x^2+y^2=0\dots(3)

From all equations

\\ \sf\longmapsto (x-y)^2=x^2+y^2-2xy

\\ \sf\longmapsto (x-y)^2=0-2(6050)

\\ \sf\longmapsto (x-y)^2=-12100

\\ \sf\longmapsto (x-y)=110\dots(4)

Now

Adding 3 and 4

\\ \sf\longmapsto 2x=220

\\ \sf\longmapsto x=110m

One side won't be covered hence

  • y=2(110)=220m
