Estimate 91 +94 by first rounding each number to the nearest ten.

Answer:

about 180

Step-by-step explanation:

(when rounding, numbers 0-4 "stay" meaning you'd round down. If the numbers are 5-9, you round up)

91 rounded to the nearest ten would be 90

94 rounded to the nearest ten would be 90 as well

So, 90 + 90 = 180

Technically though, 91+94 = 185. So rounding this to the nearest ten would be 190.

Do what you will :)

Graphing functions <br> f(x)=x^2-6x-27/x+3
hammer [34]
Funny, this looks like a complex graph, until you realize that the numerator can be written like (x+3)(x-9).

So really, this is a straight line f(x) = x-9.

But wait, there's a catch. x≠3, because that would divide by zero. So in your straight line, you have to draw a "hole" at (3,6)

zloy xaker [14]

<em><u>Complete Question:</u></em>

A colony of flowers is pollinated by hummingbirds and sunbirds. Let H represents the number of hummingbirds and S represent the number of sunbirds that must pollinate the colony so it can survive until next year.

6H+ 4S> 74

This year, 8 hummingbirds pollinated the colony. What is the least number of sun birds that must pollinate the colony to ensure that it will survive until next year?

<em><u>Answer:</u></em>

The least number of sun birds is 7

<em><u>Solution:</u></em>

Given inequality is:

6H + 4S > 74

Where,

H is the number of hummingbirds

S is the number of sunbirds

This year, 8 hummingbirds pollinated the colony

Substitute H = 8 in given inequality

6(8) + 4S > 74

48 + 4S > 74

Subtract 48 from both sides

48 + 4S - 48 > 74 - 48

4S > 26

Divide both sides by 4

S > 6.5

Hence the least number of sun birds is 7

Jonathan uploaded some original songs and also some pictures. alissa uploaded four times as many songs, but only uploaded twice
lesya [120]

X is the number of songs and Y the number of pics

our 2 equations will be - X+y=11 & 4x+2y=24

consider x=11-y

Lets replace x in 2:

=4(11-y) +2y=24

=44-4y+2y=24

=44-24= 4y-2y

=20= 2y

=Y=20/2

=Y=10

Lets replace y in 1

=X+10=11

=X=11-10

=X=1
