Solve for p
2p + 3 > 2 (p – 3)
Answer:
All real numbers
Step-by-step explanation:
[tex]2p+3 > 2(p-3)[/tex]
1. Distribute the 2 on the right side of the inequality.
[tex]2p+3 > 2p-6[/tex]
2. Cancel out the 2p on both sides of the equation since they are equal.
[tex]3 > -6[/tex]
The statement above is always true, meaning that p can be all real numbers, therefore having all real solutions.
If a(x) = 2x - 4 and b(x) = x 2, which of the following expressions produces a quadratic function? (ab)(x) (startfraction a over b endfraction) (x) (a – b)(x) (a b)(x)
The expressions which produce a quadratic function is the product of the provided binary functions (ab)(x).
A quadratic function is the function in which the unknown variable is one and the highest power of the unknown variable is two. The standard form of the quadratic function is,
[tex]f(x)=ax^2+bx+c[/tex]
Here,(a,b, c) is the real numbers and (x) is the variable.
The two function for the variable x is given as,
[tex]a(x) = 2x - 4[/tex]
[tex]b(x) = x +2[/tex]
These are the binary function, and the product of two binary function provide a quadratic function. The product or the multiplication of these two function will provide a quadratic function. Thus,
[tex]a(x) b(x)= (2x - 4)(x+2)\\(ab)(x)=2x^2+4x-4x-8\\(ab)(x)=2x^2-8[/tex]
Thus, the expressions which produce a quadratic function is the product of the provided binary functions (ab)(x).

Answer:
x = -166, y = 34
Step-by-step explanation:
5(x+2y) - 3 = 3x+5
4(x-3y) - 50 = -33y
Open both equations
5x+10y - 3 = 3x+5
2x+10y = 8
4x-12y - 50 = -33y
4x+21y = 50
Now multiply -2 on both sides of 1st equation.
(easier to add both equations.)
-4x+-20y = -16
4x+21y = 50
Add both equations
x cancels out
y = 34
plug y back into other equation to find x
2x + 340 = 8
2x = -332
x = -166
Answer:
y = 34, x = -166
Step-by-step explanation:
Let's simplify the first equation.
5(x + 2y) - 3 = 3x + 5
We can multiply the 5 out:
5x + 10y - 3 = 3x + 5
Now let's isolate x on one side, although you can choose to isolate y if you want to. Subtract 3x on both sides:
2x + 10y - 3 = 5
Add 3 on both sides and subtract 10y on both sides.
2x = 8 - 10y
Divide 2 on both sides.
x = 4 - 5y
Now to the next equation!
4(x - 3y) - 50 = -33y
Multiply 4 out:
4x - 12y - 50 = -33y
Add 12y and 50 on both sides.
4x = -21y + 50
Now divide 4 on both sides!
x = -5.25y + 12.5
Now we have these equations:
x = 4 - 5y
x = -5.25y + 12.5
Therefore 4 - 5y = -5.25y + 12.5
Once again let's isolate the variable. Let's add 5.25y on both sides and subtract 4 on both sides:
0.25y = 8.5
Now multiply by 4 on both sides to bring y's coefficient to 1:
y = 34
Let's substitute the y value into the equation x = 4 - 5y to get x = 4 - 136 = -132

If Section 1 uses concrete to cover approximately 9 square feet, which is closest to the total
area that will be covered with the concrete sections?
40 square feet
B. 55 square feet
C 70 square feet
D. 95 square feet
According to the information, it can be inferred that the option that is closest to the area occupied is 40 square feet (option A).
How to calculate the total area covered with brick and concrete?To calculate the total area covered with brick and concrete we must identify how many sections of brick the garden will have, according to the image it can be inferred that there are four sections of brick and concrete in total.
According to the above, what we must do is multiply the area of the section by the number of sections (4).
9 square feet × 4 = 36 square feet.So option A, 40 square feet is the closest to the total area occupied by bricks. Then it would be the correct option.

Answer:
408in[tex]^{2}[/tex]
Step-by-step explanation:
1.) First, find the area of the base (**If you don't know how to do this, just find the length and width, then multiply them together). Since there aren't any other measurements, I'm guessing all sides are 12 inches (12x12=144).
2.) Next, find the area of the triangle. Use 12 and 11 as your measurements in this case (12x11=132).
3.) Now, divide your answer from step 2 (132) by 2 (132/2=66). This is because usually, triangles are HALF of the area of a square. If you skip this step, you will have made a cube instead of a pyramid.
4.) Multiply the answer from step 3 (66) by 4 (66x4=264), since there's 4 triangles on the pyramid.
5.) Add the answer from steps 4 (264) and 1 (144). This should get you the TOTAL surface area (408in[tex]^{2}[/tex]).

The number of ways 5 puppies can be chosen from a litter of 8 puppies is 56 ways
Permutation and CombinationPermutation has to do with arrangement while combination has to do with selection.
From the queston, since we are to select 5 puppies from a litter of 8 puppes, this can be done as shown:
8C5 = 8!/(8-5)!5!
8C5 = 8!/3!5!
8C5 = 8*7*6*5!/6*5!
8C5 = 8* 7

Answer and show all of your work.
Answer:
105 shifts
Step-by-step explanation:
Hourly net rate of pay = $12
1 shift = 8 hours
⇒ net pay per shift = $12 × 8 = $96
Total cost = tuition + residence + books
= $4500 + $4800 + $700
= $10,000
To calculate how many shifts Joanne needs to work, divide the total cost by the pay per shift and round it up:
Number of shifts = total cost ÷ net pay per shift
= $10,000 ÷ $96
= 104.1666666...
= 105 shifts
Note: we need to round up, as if Joanne works 104 shifts, she will earn $9,984 which is not quite enough to pay for tuition, residence and books.
If we know the value of b, the slope of the regression line, we can accurately guess the value for the correlation coefficient without looking at the scatterplot.

B. False
Answer:
A True
Step-by-step explanation:
I am in 12th grade and make straight A's trust me on the answer
Yes it is true that if we know the value of [b], the slope of the regression line, we can accurately guess the value for the correlation coefficient without looking at the scatterplot.
What is Scatterplot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.
Given is the statement -
" If we know the value of [b] the slope of the regression line, we can accurately guess the value for the correlation coefficient without looking at the scatterplot ".
A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict change to the value of another. Mathematically, it is given by -
[tex]$r =\frac{\sum\left(x_{i}-\bar{x}\right)\left(y_{i}-\bar{y}\right)}{\sqrt{\sum\left(x_{i}-\bar{x}\right)^{2} \sum\left(y_{i}-\bar{y}\right)^{2}}}[/tex]
The slope of the regression line can be used to estimate the correlation coefficient without looking at the scatterplot. For '+' slope, the correlation coefficient is positive and for '-' slope the correlation coefficient is negative.
Therefore, yes it is true that if we know the value of [b], the slope of the regression line, we can accurately guess the value for the correlation coefficient without looking at the scatterplot.

In a state lottery, there are 12 finalists who are eligible for the Big Money Draw. In how many ways can the first, second, and third prizes be awarded if no ticket holder can win more than one prize? ways
Answer: 1320 ways
Step-by-step explanation:
In this scenario, 12 finalists are eligible for the money draw and no finalist can win more than one prize.
So for the 1st prize we have 12 finalists
For the 2nd prize we have 11 finalists
And finally, for the 3rd prize we have 10 finalists
Using the multiplication principle:
Total number of ways = 12 x 11 x 10
= 1320
Therefore, there are 1320 ways the first, second, and third prizes be awarded
