which of the following is the correct graph of the compound inequality 4p+1>-7 or 6p+3<33
( the answers^)

Answer:

Answer should be x^9

Step-by-step explanation:

This equation looks really complicted, but it's actually much easier when you break it down! First, your going to multiply the fraction 3/2 by 6 - since one is a fraction, youre going to find the GCF, or Greatest Common Factor, and reduce it. The GCF in this equation is 2, so we eliminate the two from the fraction (making it just 3) and divide 6 by 2 (getting 3). Thus, we are left with (x^3)^3 -> 3 x 3 = 9. So we are left with x^9. I hope this helps!

Answer:

ab = 1/2.

Step-by-step explanation:

The sides of the large square have length √5 while the sides of the small one have sides of length 2.

Each corner has a right triangle with legs of length a and b and hypotenuse 2.

So we have the system

a + b = √5

a^2 + b^2 = 2^2 = 4

Using the identity   a^2 + b^2 =  (a + b)^2 - 2ab:

4 = (√5)^2 - 2ab

4 = 5 - 2ab

2ab = 5 - 4 = 1

ab = 1/2.

Answer:

Step-by-step explanation:

To get the product of the function (y x - 5)(y x + 5), we will have to expand the bracket as shown;

= (y x - 5)(y x + 5)

= (yx)² + 5yx-5yx- 5(5)

= (yx)² + 5yx-5yx- 25

=(yx)² +0- 5(5)

= y²x² - 25

The product is expressed as y²x² - 25

Answer:

The person above me is *almost* right. but the x's are exponents.

Step-by-step explanation:

The right answer is y^2x-25. I hope this helps you! <3

Answer:

Option B.

Step-by-step explanation:

We need to find a pair of lines that represents the equations with the solution (4, −1).

Since (4,-1) is the solution of the equations. It means (4,-1) is the intersection point of lines.

4 on x-coordinate means 4 units right.

-1 on y-coordinate means 1 unit down.

A coordinate grid is shown from negative 8 to positive 8 on the x axis and also on the y axis. A pair of lines is shown intersecting on ordered pair 4 units to the right and 1 unit down.  

Therefore, the correct option is B.

Answer:

7.5 cm

Step-by-step explanation:

it is a right triangle, b=10, hypotenuse c=12.5

a^2+b^=c^2 the Pythagorean theorm

a^=c^2-b^2

a^2= 12.5^2-10^2

      = 56.25

a=√56.25=7.5 cm

Answer: 2.5%

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:  

A = P (1 + r/n) nt  

Where:  

A = Future value of investment (principal + interest)  

P = Principal Amount  

r = Nominal Interest Rate (decimal form, 10/100= 0.1)  

n= number of compounding periods in each year (365)  

Replacing with the values given  

A=250(1+0.1/1)^t/1

A=250(1.1)^t

For a interest compounded annually, n=1, compounded quarterly n= 4 (4quarters in a year )

Interest rate 0.1 /4 = 0.025= 2.5%

Answer:

9.6%

Answer:

{(−5,−3),(−3,2),(3,3),(9,3)}

{(−5,−3),(6,−4),(9,−5),(−2,−5)}

{(7,−1),(4,7),(0,−1),(2,14)}

Step-by-step explanation:

These 3 answer choices all represent functions since the x-values only correspond to one y-value.

The other answer choices are not functions because some of the x-values correspond to more than one y-value.

Answer:

x = 10

y = 70

Step-by-step explanation:

By using the vertical angles theorem we know that x+ y +10 = 90, also simplified to x + y = 80

and 2x + y = 90

By using the substitution method on x + y = 80, it will be y = -x + 80

When you put into the equation 2x + y = 90 you will get 2x -x +80 = 90

Then it will simplify to x = 10

After that plug 10 into x + y = 80 to 10 + y = 80 and get y = 70

Answer: y = -6x + 5

Step-by-step explanation:

equastion is y = dx + e

+) Because it perpendicular y = \dfrac{1}{6} x + 3

d \times \dfrac{1}{6} = -1

<=> d =  -1 : \dfrac{1}{6}

<=> d = -6

=> y = -6x + e;

+) Because it contains the point (-3; 23)

=> 23 = -6 \times (-3) + e

<=> e = 5

=> y = -6x + 5

Answer:

11 gallons

Step-by-step explanation:

We can set up a proportion.

g represents gallons of punch.

24/144=g/66

We can simplify the left side:

1/6=g/66

We cross multiply.

6g=66

g=11

You need 11 gallons of punch to serve 66 guests!

Answer: C

Step-by-step explanation:

This is the answer because you have to multiply (x-1) on both sides and that will cancel out the denominator on the right. Then, multiply by x on both sides and that will cancel the denominator on the left side. When you do this, C should be your answer. Hope this helps :)

Answer:

75%.

Step-by-step explanation:

The increase in miles = 3.5 - 2 = 1.5.

So the percent increase = (1.5 / 2.0) * 100

= 0.75 * 100

= 75%.

Answer:75%

Step-by-step explanation

Her progress 3.5-2=1.5

2 miles progressed by 1.5 miles

1 miles progressedby 1.5/2 miles

100 miles progressedby ( 1.5/2)x 100

=75℅

Answer:

42, because PQ is split in half and one side is 21, the 2 little lines going thru it show that both sides are equal meaning PQ is 42 bc of 21+21 therefore so is SR

Answer:

Step-by-step explanation:

Lets start by defining the numbers in the equation.

This  equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same

In slope-intercept form,

Th equation is y=400+32x so now we know

For the first question the change per minute is the rate so it is 32.

For the second question the starting amount is the same as the y-intercept so it is 400.

Answer:

C) y = -(x + 3)2

Step-by-step explanation:

To vertically shrink the function by a factor of 1/2, we just need to multiply f(x) by 1/2 (This way the values in the y-axis will decrease by a factor of 1/2):

[tex]y = (1/2) * 2(x + 3)^2[/tex]

[tex]y = (x + 3)^2[/tex]

Now, to reflect the function across the x-axis, we just need to put a minus sign in the front of the function (so the values in the first and second quadrant will go to the third and fourth quadrant, that is, f(x) will be -f(x)):

[tex]y = -(x + 3)^2[/tex]

So the correct option is C)

Answer:

C. Cheryl accelerated to 65 mph, drove at a constant speed for 5.5 minutes, and then decelerated to 45 mph.  

Step-by-step explanation:

Assume the graph of Cheryl's commute was like the one below.

We see that she started at 0 mph.  

One minute later, she was up to 65 mph, so she had accelerated (increased her speed).

At 6.5 min (5,5 min later) her speed was still 65 mph, so she was driving at a constant speed.

Over the next 2.5 min, her speed dropped to 45 mph, so she was decelerating.

Short Answer:

1. C ( 60 degrees)

2. B (90 degrees)

Explanation:

The first one is 60 degrees, because every 5 minutes the minute hand goes 30 degrees and she took 10 minutes.

30 x 2

=60 degrees

The second one is 90 because one section is 30 degrees. so,

30 x 3

= 90 degrees

Answer: The answer is "experiment."

Step-by-step explanation:

This procedure is being used in order to validate a hypothesis, particularly in a research study. In the situation above, you have to validate whether a new reading program can increase reading comprehension or not.

The experiment consists of independent, dependent, and controlled variables. The independent variables are the ones being changed by the researcher, while the dependent variables tell whether the changes in the independent variable is significant. The controlled variables are the ones that are constant.

The dependent variable above is reading comprehension, while the new reading program is the independent variable. Examples of controlled variables are the ages of the participants. The age directly affects the reading comprehension, thus it has to be considered.

Answer:

D. 9

Step-by-step explanation:

From the question, we are given the following information:

The number of tennis balls represented by P(n), in n layers of the square pyramid is given as

P(n) = P(n - 1) + n²

In other to solve for n, we would be taking some values for n

Step 1

Let's take the first layer,

n is represented by 1

n = 1

P(1) = P(1 - 1) + 1²

P(1) = 1 tennis ball.

Step 2

Let's take the second layer

n is represented by 2

P(2) = P(2 - 1) + 2²

P(2) = P(1) + 2²

Note that: P(1) above = 1

P(2) = 1 + 2²

P(2) = 5 tennis balls

Step 3

Let's take the third layer

n is represented by 3

P(3) = P(3 - 1) + 3²

P(3) = P(3 - 1) + 3²

P(3) = P(2) + 3²

Note that: P(2) above = 5

P(3) = 5 + 3²

P(3) = 14 tennis balls

Step 4

Let's take the fourth layer

n is represented by 4

P(4) = P(4 - 1) + 4²

P(3) = P(4 - 1) + 4²

P(3) = P(3) + 4²

Note that: P(3) above = 14

P(3) = 14 + 4²

P(3) = 30 tennis balls

We can continue this process, on and on

From the above solution for the number of the tennis balls in first four layers will be: 1, 5, 14, 30,

Hence, the number of tennis balls that Coach Kunal could not have is 9.
