Answer:

In Quadrant I or III

Step-by-step explanation:

We know if the sign was not showing closed inequality facing other way

xy < 0 would be in the 2nd or 4th quadrant.

If xy = 0  then either xy or both are on the x or y axis

But if xy>0 then they are in quadrant I or III

If xy>0, then the points of P(x,y) lies in Quadrant I and III

According to the given condition;

This means that the product of x and y is a positive number.

Hence, either both x and y-coordinates are positive or are both negative

Hence, only points in the Quadrant I have positive x and y coordinates Or Quadrant III in which case all x and y values are negative.

Answer:

200 miles

Explaination:

in order to fiind the point of interaction you must put the world problem into an liner equation.

y=mx+b

key:

miles : x

y= 0.70x + 120

&

y= 0.90x + 80

now you put them together

0.70x + 120 = 0.90x + 80

-0.70x. -0.70x

____________________ subtract slope from both sides

120 = 0.20x + 80. ( doesn't matter which one)

-80 - 80

____________________ subtract

40 = 0.20x

_________ Divide each # with the slope

0.20 0.20

200 = x

Answer: D. Square

The cross section is shown as the shaded region. There are four sides to the shaded figure, so the cross section is a quadrilateral. This rules out choice C. We can also cross choice B off the list because cross sections of 3D figures are 2 dimensional.

Choice A is ruled out as well because we have both pairs of opposite sides that are parallel. The only thing left is choice D. This is true assuming we have a square prism. Any cube is a square prism that has its height equal to the width and length.

Answer:

[tex]Range = [24, 375][/tex]

Step-by-step explanation:

Given

[tex]f(x) = 3x^3[/tex]

[tex]Domain = [2,5][/tex]

Required

Find the Range

The range is calculated by solving for f(2) and f(5). In other words, the range is calculated when x is 2 and x is 5

When x = 2;

f(2) is as follows;

[tex]f(2) = 3*2^3[/tex]

[tex]f(2) = 3 * 8[/tex]

[tex]f(2) = 24[/tex]

When x = 5;

f(5) is as follows;

[tex]f(5) = 3*5^3[/tex]

[tex]f(5) = 3 * 125[/tex]

[tex]f(5) = 375[/tex]

Hence, the range of the function is [24, 375]

Answer:

Step-by-step explanation:

When taking out the absolute value, it's 4x+2=6 and 4x+2=-6. At this point just solve for x and your answer(s) should be 1/-2

Answer:

x =1   x=-2

Step-by-step explanation:

|4x +2|= 6

There are two solutions a positive and a negative

4x+2 = 6      and 4x+2 = -6

Subtract 2 from each side

4x+2-2 = 6-2      4x+2-2 = -6-2

4x = 4                     4x = -8

Divide by 4

4x/4 = 4/4            4x/4   =-8/4

x =1                            x = -2

[tex]-18n^4-2n^3-5n^2+8[/tex]

Step-by-step explanation:

[tex](-9n^4+8)-(9n^4+2n^3+5n^2)= \\\\-9n^4 - 9n^4 + 8-2n^3-5n^2= \\\\-18n^4-2n^3-5n^2+8[/tex]

Hope this helps!

Steps:

Distribute the Negative Sign:

=-9n⁴+8+-1(9n⁴+2n³+5n²

=-9n⁴+8+−1(9n⁴)+−1(2n³)+−1(5n²)

=−9n⁴+8+−9n⁴+−2n³+−5n²

Combine Like Terms:

=−9n⁴+8+−9n⁴+−2n³+−5n²

=(−9n⁴+−9n⁴)+(−2n³+(−5n²)+(8)

=−18n⁴+−2n³+−5n²+8

Description:

The first steps is to distribute the Negative Sign, after you do it your equation will end like =−9n⁴+8+−9n⁴+−2n³+−5n². Second step is to Combine Like Terms/factors. When you do it your equation will end like=−18n⁴+−2n³+−5n²+8. And that will be the answer to simplify.

Answer:

A: 5/23

Step-by-step explanation:

First, lets take the total amount of coins in the jar: 8 nickels, 10 dimes, 6 quarters, and 22 pennies- for a total of 46 coins.

The question is asking what the odds of pulling a dime are.

Since there is 46 coins in the jar, you can just do a fraction and set it up like this:

10

46

From there just simplify the fraction, 10 / 2 = 5, 46 / 2 = 23. The problem can't be simplified further, so the answer you originally had was correct. 5/23

D- John does not wear his school colors and does not attend any school event.

Description in mathematics, a conjecture is a conclusion or a proposition which is suspected to be true due to preliminary supporting evidence, but for which no proof or disproof has yet been found.

The counter-example for the given conjecture is "John does not wear his school colours and does not attend any school event". Therefore, option D is the correct answer.

The given conjecture is "All students have school pride."

We need to identify a counter-example for the given conjecture.

In mathematics, a conjecture is a conclusion or a proposition that is proffered on a tentative basis without proof. Some conjectures, such as the Riemann hypothesis or Fermat's Last Theorem, have shaped much of mathematical history as new areas of mathematics are developed in order to prove them.

Now, "All students have school pride" is not true, because not all students have school pride.

The counter-example for this conjecture is "John does not wear his school colours and does not attend any school event"

Therefore, option D is the correct answer.

Answer:

16/24

Step-by-step explanation:

let’s use the GCF of both which is 3 for 15/27

15/27 divided by 3 is 5/9

for 16/24 the gcf is 8

16/24 / 8 is 2/3

now we have to multiply 2/3 times 3

2/3 times 3 6/3 which is 2

so 16/24 is greater.

Answer:

105 cars

Step-by-step explanation:

150cars=100%

and if 30% of the cars are sedans then the cars which are not sedans is

100%-30% =70%

if 150 cars=100%

? cars=70%

if less more devides

70%/100%×150cars

all zeros cancel which would be left with

7× 15

105 cars.

Answer:

The answer is 105

So that 30% of those cars are 45 Sedans of the 150 cars.

Now we need to find out how many cars are in that remaining 70%

In order to do this we need to subtract 45 from 150

So 150 minus 45 is 105

Finally, we know that that remaining 70% is 105 cars that aren't Sedans.

So 105 cars are not Sedans.

Answer:

A. y=-3x+4

Step-by-step explanation:

Since the equation is in y=mx+b form, m represents the slope of a line. To solve for slope-intercept, use the equation m=(y2-x2)/(y1-x1).

[tex]m=\frac{-2-4}{2-0}[/tex]

[tex]m=\frac{-6}{2}[/tex]

[tex]m=-3[/tex]

Make sure to plug in one of the points into the equation to check if the numbers equal to one another or not.

Answer:

Which is the most efficient way to solve this equation?

+4=17

Subtract 4

from both sides because that will result in an equivalent equation with

alone on one side.

Subtract 17

from both sides of the equation so all terms will be on the same side of the equal sign.

Nothing, because the equation is already solved.

Add 4

to 17

because

equals 21.
