Answer:

I can't show a graph!

Step-by-step explanation:

Ok first, graph the top function then the bottom one.

On the top one, solve the equation until you hit x = 3, as this is where you have to stop.

You would then start solving the bottom function for any value of x over 3.

It's like this, while x is less than 3, graph 2x, if it is over 3, graph -1/3x + 7. There can be a break in the graph between the two equations.

Hope this helps!

Can someone help me with this? (5+w)(w+4)

mel-nik [20]

Answer:

w^2+9w+20

Step-by-step explanation:

Apply the FOIL METHOD: (a + b) (c + d) = ac + ad + bc + bd

a = 5

b = w

c = w

d = 4

= 5w + 5 x 4 + ww + w x 4

= 5w + 5 x 4 + ww + 4w

Simplify 5w + 5 x 4 + ww + 4w:

w^2 + 9w + 20

Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 sq feet. Write and solve a propo

avanturin [10]

First, I would find the total area that Lisa needs to paint.
26x7=182 square feet

If a gallon of paint will cover 350 square feet, we will need to find out how many are needed to cover the fence.
g=gallons
350g=182
g=0.52 gallons of paint are needed

geniusboy [140]

Answer:

Integers and polynomials are both closed under addition, subtraction, and multiplication; however, operations on polynomials can sometimes be open while operations on integers produce irrational results .

Step-by-step explanation:

Closed means that addition, subtraction, and multiplication of integers gives as result a new integer; and addition, subtraction, and multiplication of polynomials gives as result a new polynomial.

Operations on polynomials can sometimes be open, like in division.

Operations on integers can produce irrational results , for example, dividing 11 by 9.
