Answer:
Step-by-step explanation:
The third, fifth and sixth expressions (from the top) are NOT polynomials, and the reason in each case is that the expression has one or more negative powers of x in it.
the sum of the reciprocals of two consecutive even intergers is 9/40 this can be represented bby the equation shown 1/x+1/x+2=9/40 use the rational equation to determine the integers
SHOW YOUR WORK PLEASE!!!!!!!
Answer:
In explanation
Step-by-step explanation:
To solve the rational equation 1/x + 1/(x + 2) = 9/40, we can start by finding a common denominator and then simplifying the equation. The common denominator for the two fractions is (x)(x + 2). Multiplying each term by this common denominator, we get:
[(x + 2) + x] / (x)(x + 2) = 9/40
Simplifying the numerator, we have:
(2x + 2) / (x)(x + 2) = 9/40
Now, we can cross-multiply to eliminate the denominators:
40(2x + 2) = 9(x)(x + 2)
Expanding both sides, we have:
80x + 80 = 9x^2 + 18x
Rearranging the equation and setting it equal to zero:
9x^2 - 62x - 80 = 0
Now, we can factor the quadratic equation:
(9x + 10)(x - 8) = 0
Setting each factor equal to zero, we have:
9x + 10 = 0 or x - 8 = 0
Solving for x in each case:
9x = -10 or x = 8
Dividing both sides of the first equation by 9, we find:
x = -10/9 or x = 8
Since we are looking for even integers, we can disregard the negative solution. Therefore, the value of x is 8.
Hence, the two consecutive even integers can be represented by x and x + 2, which gives us 8 and 10. So, the integers are 8 and 10.
Solve and identify the graph of each inequality.

This work is way to hard and my work is stacking it would be nice to have some weight off my back
1) Popcorn unit price: 17.57/7 = $2.51
2.51 x 3 = 7.53
Three bags of popcorn would cost $7.53.
2) Old games unit price: 73.10/5 = 14.62
14.62 x 6 = 87.72
If they sold six games they would've made $87.72.
3) Lollipop unit price: 20.51/7 = %2.93
2.39 x 4 = 11.72
Four lollipops would cost $11.72
4) Hotdogs unit price: 82.86/3 = $27.42
Hamburgers unit price: 55.12/2 $27.56
Hotdogs have the lower unit price. $27.42 < $27.56
5) Packs of paper unit price: 12.74/7 = $1.82
1.82 x 2 = 3.64
Two packs of paper would cost $3.64
6) Pair of shoes unit price: 49.32/4 = $12.33
12.33 x 6 = $73.98
Six pairs of shoes would cost $73.98
7) Brand A unit price: 71.28/6 = $11.88
Brand B unit price: 59.15/5 = $11.83
Brand B has the cheaper price. $11.83 < $11.88
8) Pounds of seeds unit price: 37.62/2 = $18.81
18.81 x 6 = $112.86
Six pounds of seeds would cost $112.86
9) Red Grapes unit price: .82
Green Grapes unit price: .84
Green grapes are more expensive. .84 > .82
10) Book Store unit price : 21.69/3 = $7.23
Online unit price: 14.28/2 = $7.14
Online has a lower unit price. $7.14 < $7.23

Omar wants to rent a boat and spend at most $40. The boat costs $6 per hour, and Omar has a discount coupon for $8 off. What are the possible numbers of hours Omar could rent the boat?
Use t for the number of hours.
Write your answer as an inequality solved for t.
Answer:
8 ≥ t
Step-by-step explanation:
The inequality that best models the situation is 40 ≥ 6t - 8, since Omar wants to spend at most (i.e., no more than) $40, the boat costs $6/hr, and he has a discount coupon for $8 off.
Now we can solve for t:
Step 1: Add 8 to both sides:
(40 ≥ 6t - 8) + 8
48 ≥ 6t
Step 2: Divide both sides by 6 to solve for t:
(48 ≥ 6t) / 6
8 ≥ t
Thus, Omar can rent the boat for no more than 8 hours in order to not exceed his $40 spending limit.

A=m/360pi times radius to the power of 2. Given the measure m of the angle and the radius r of a circle.
Find the measure of the angle if the area of the sector is 5 square centimeters and the radius is 2 centimeters. Round your answer to the nearest tenth.
\(A=\dfrac{m}{360}*\pi r^2\)
A = area of sectorm = measure of angle in degreesr = radiusSolving the Question
We're given:
A = 5 cm²r = 2 cmm = ?Plug the given information into the equation and solve for m:
\(A=\dfrac{m}{360}*\pi r^2\\\\5=\dfrac{m}{360}*\pi (2)^2\\\\5=\dfrac{m}{360}*4\pi \\\\\dfrac{5}{4\pi}=\dfrac{m}{360}\\\\m=\dfrac{5*360}{4\pi}\\\\m=143.2\)

From Dan's ranch one road is built to get to Andy's house and two roads are built to get to Willie's house (see previous problem). How many way are there now to get from Andy's house to Willie's house?
Answer: There are ways now to get from Andy's house to Willie's house.
Step-by-step explanation:
Given, from Dan's ranch one road is built to get to Andy's house and two roads are built to get to Willie's house.
Then, the number of ways to get from Andy's house to Willie's house =
(Number of ways to Andy's house) x (Number of ways to get Willie's house) [Using fundamental counting principle]
= 1 x 2 = 2
Hence, there are ways now to get from Andy's house to Willie's house.

Question: What is the value of r.
Which calculation results in the best estimate of 148% of 203? (200) (140 percent) = (200) (100 percent + 40 percent) = (200) (100 percent) + (200) (40 percent) = (200) (1.0) + (200) (0.4) = 200 + 80 = 280 (210) (140 percent) = (210) (100 percent + 40 percent) = (210) (100 percent) + (210) (40 percent) = (210) (1.0) + (210) (0.4) = 210 + 84 = 294 (200) (150 percent) = (200) (100 percent + 50 percent) = (200) (100 percent) + (200) (50 percent) = (200) (1) + (200) (one-half) = 200 + 100 + 300 (210) (150 percent) = (210) (100 percent + 50 percent) = (210) (100 percent) + (210) (50 percent) = (210) (1) + (210) (one-half) = 210 + 105 = 315
Answer:
the best calculation for an estimate would be to do 150% of 203 which is 300
