Answer:

A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.

A binomial has two terms. For example: 5x2 -4x

A trinomial has three terms. For example: 3y2+5y-2

You can’t decide which estate agent to use to sell your home, so you research the number of properties each estate agent has sol

Triss [41]

Answer:

B. 130 70

Step-by-step explanation:

Agent B sold the highest number (53.85% ) of houses given the number of listed houses.

Find the percentage of houses each agent sold.

For A

x/100 * 150 = 75

cross multiply and find x, that would be 50%

For B

x/100 * 130 = 70

cross multiply and find x, that would be 53.85%

for C

x/100 *145 = 75

cross multiply and find x, that would be 51.72%

v - 6 ≥ 4

+6 +6

v ≥ 10

Graph: 10 -----------------→ the dot at 10 is filled in because of the "equal to" symbol

********************************************************************************************************

-5x < 15

$\frac{-5x}{-5} > \frac{15}{-5}$ divided by a negative so the symbol flipped

x > -3

Graph: -3 o------------------→ the dot at -3 is NOT filled in because it's NOT "equal to"

********************************************************************************************************

3k > 5k + 12

-5k -5k

-2k > 12

$\frac{-2k}{-2} < \frac{12}{-2}$ divided by a negative so the symbol flipped

k < -6

Graph: ←------------o -6 the dot at -6 is NOT filled in because it's NOT "equal to"

********************************************************************************************************

2t ≤ 4 or 7t ≥ 49

$\frac{2t}{2} \leq\frac{4}{2}$ or $\frac{7t}{7} \geq \frac{49}{7}$

t ≤ 2 or t ≥ 7

Graph: ←------- 2 7 ---------→ the dots at 2 and 7 are filled in

| n + 2 | = 4

n + 2 = 4 or n + 2 = -4

-2 -2 -2 -2

n = 2 or n = -6

Answer: n = {2, -6}

2x > 8 or 2x < 6

$\frac{2x}{2} > \frac{8}{2}$ or $\frac{2x}{2} < \frac{6}{2}$

x > 4 or x < 3

********************************************************************************************************

A = {1, 2, 3, 4, 5, 6, 7, 8, 9} B = {2, 4, 6, 8}

A U B = {1, 2, 3, 4, 5, 6, 7, 8, 9} union combines both sets

A ∩ B = {2, 4, 6, 8} intersection includes only those that are in BOTH sets

********************************************************************************************************

P = {1, 5, 7, 9, 13} R = { 1, 2, 3, 4, 5, 6, 7} Q = {1, 3, 5}

P ∩ R ∩ Q = {1, 5}

P ∩ R = {7} disregard 1 & 5 since they are already in P∩Q∩R

R ∩ Q = {3} disregard 1 & 5 since they are already in P∩Q∩R

P ∩ Q = { } disregard 1 & 5 since they are already in P∩Q∩R

P no intersection = {9, 13)

R no intersection = {2, 4, 6}

Q no intersection = { }

If you can't figure out how to draw it based on the information I provided, please see the attached diagram. Note: Usially, you would only identify P, Q, R. I identified the intersections so you would understand why those specific numbers are placed in the designated sections.
