Let f(x)=2x^4+x^3+x^2-3x+r. For what value of r is f(2)=0?

Answers

Answer 1

Answer:

the answer is 0

Step-by-step explanation:

Answer 2

Answer:

r = -38

Step-by-step explanation:

For what value of r in the formula:  f(x)  =  2x4 + x3 + x2- 3x + r  does  f(2)  =  0?

Replace x with 2:  2·24 + 23 + 22- 3·2 + r  =  32 + 8 + 4 - 6 + r  =  38 + r

This value is to equal 0:   38 + r  =  0

                                                r  =  -38

QUESTION: How does the Indian reservation have an effect on the right of occupancy

THESE ARE MY NOTES THE ANSWER IS IN IT

Neither the Secretary of the Interior, Congress, or any other branch of government, has the Constitutional power to disregard the Right of Occupancy and this fact is settled government policy. Congress has recognized Original Indian Title in several state enabling acts (or acts of Congress officially creating/recognizing a state) by requiring the incoming state to disclaim all right and title to lands owned or held by any Indian or Indian tribe. From our class discussion on Discovery, what the Treaty of Guadalupe Hidalgo transferred to the United States was the right to purchase/conquer the lands of that territory from tribes (the Federal Government cannot grant what it does not have). Where no land cession has been freely made by a tribe, Original Indian Title remains unaffected. So, the second right of Original Indian Title is to transfer that title to the sovereign possessing the right of Discovery. When the United States would attempt to purchase land of Native Americans, “Indian reservations” were created by removing those lands from the purchase so the tribe would continue to hold Original Indian Title within those boundaries.
Original Indian Title contains two very basic rights, the right to occupy the lands involved and the right to sell those lands to the government who possesses the right of Discovery. Though the United States had the right to conquer Native American lands to claim possession, the fact is that the common approach was to avoid military conflict and to purchase those lands instead.

Steve had $140.50 dollars. He loaned $50 dollars to a friend, spent $31.25 dollars, and received his $80.75 dollars paycheck from work. How much money does he have now? Show your work

Answers

Answer:

Steve has a total of $140.

Step-by-step explanation:

At first, we know that Steve has $140.50. Next, he loaned $50 to a friend. This tells us that this money went out of his account.

140.50 - 50 = $90.50

So now, Steve has only $90.50 left.

Then, he spent $31.25. This also tells us that his went out of his account, so we must subtract it.

90.50 - 31.25 = $59.25

Now, Steve has $59.25 left.

Finally, Steve received an $80.75 paycheck from work. This tells us that this money went in to his account.

59.25 + 80.75 = $140

Therefore, Steve now has a total of $140.

Solve the following system of equations using substitution. Show ALL of your work and write the ordered pair in the space provided. y = x - 1 y = 2x + 1

Answers

Answer:

substitution method would go as follows

5x-2=7x-8 we than rearange it so it becomes 5x-7x=-8-2 this than becomes -2x=-6 so x=3

we can than substitute 3 for x in one of the first equations

y=7 times 3-8 = 21-8 = 13

so therfore the interception should be at 3,13

Step-by-step explanation:

Andre and Noah started tracking their savings at the same time. Andre started with $15 and deposits $5 per week. Noah started with $2.50 and deposits $7.50 per week. The graph of Noah's savings is given and his equation is y=7.5x+2.5, where x represents the number of weeks and y represents his savings.

Write the equation for Andre's savings and graph it alongside Noah's. What does the intersection point mean in this situation?

Answers

Answer:5x + 15
Plzzz trust I had the same answer as well and the question too thx

An equation and the intersection point of the two lines is required.

Andre's equation [tex]y=5x+15[/tex]

The intersection point is [tex](5,40)[/tex]

This means that at 5 months both Andre and Noah will have a total of $40 savings.

Noah's equation

[tex]y=7.5x+2.5[/tex]

x = Number of weeks

y = Savings

Andre's equation

[tex]y=5x+15[/tex]

Let us find two points of each line

[tex]x=0[/tex]

[tex]y=2.5[/tex]

[tex](0,2.5)[/tex]

[tex]y=0[/tex]

[tex]x=-\dfrac{2.5}{7.5}=-0.33[/tex]

[tex](-0.33,0)[/tex]

[tex]x=0[/tex]

[tex]y=15[/tex]

[tex](0,15)[/tex]

[tex]y=0[/tex]

[tex]x=-\dfrac{15}{5}=-3[/tex]

[tex](-3,0)[/tex]

Draw lines through their respective points

The intersection point is [tex](5,40)[/tex]

This means that at 5 months both Andre and Noah will have a total of $40 savings.

Six friends go to the local sandwich shop. All six people order the combination meal, which includes a drink and a veggie wrap for $4.95. One person thinks the total bill for all six friends will be around $20.00
Is that a reasonable estimate? Why?

A. No, a reasonable estimate is around 6 times $7 = $42
B No, a reasonable estimate is around 5 times $6 = 30
C. No, a reasonable estimate is around 10 times $5 = 50
D Yes, a reasonable estimate is around 4 times $5 - $20

please help and don't just do for points

Answers

Answer:

c?

Step-by-step explanation:

B. No, a reasonable estimate is around 5 times $6 = $30

The total bill for all six friends can be estimated by multiplying the number of friends by the cost of the combination meal. Since there are six friends and each combination meal costs $4.95, the reasonable estimate for the total bill would be:

6 friends * $4.95/meal = $29.70

Since option B suggests a reasonable estimate of $30, which is very close to the calculated estimate of $29.70, it is the most appropriate choice. Option A suggests a much lower estimate than the actual cost, option C suggests a much higher estimate, and option D suggests a lower estimate without considering the actual cost of the meal.

Therefore, option B is the best choice for a reasonable estimate of the total bill for all six friends at the sandwich shop.
