Trying to factor by splitting the middle term
2.1 Factoring 2y2-5y-8
The first term is, 2y2 its coefficient is 2 .
The middle term is, -5y its coefficient is -5 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 2 • -8 = -16
Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is -5 .
-16 + 1 = -15
-8 + 2 = -6
-4 + 4 = 0
-2 + 8 = 6
-1 + 16 = 15
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

5.2 Factoring y2 + 11y + 14
The first term is, y2 its coefficient is 1 .
The middle term is, +11y its coefficient is 11 .
The last term, "the constant", is +14
Step-1 : Multiply the coefficient of the first term by the constant 1 • 14 = 14
Step-2 : Find two factors of 14 whose sum equals the coefficient of the middle term, which is 11 .
-14 + -1 = -15

Is p(4p - 9) =12 or p(4p - 9) - 12 quadratic?
pls need help
From: Brainly.ph (philippines)
Answer:
p(4p - 9) =12 ⇒ 4p² - 9p = 12 ⇒ 4p² - 9p - 12 = 0
This is a quadratic equationp(4p - 9) - 12 ⇒ 4p² - 9p - 12
This is a quadratic expressionStep-by-step explanation:
p(4p-9)=124p²-9p=12Since, it's one term has power 2 ,so it is quadratic
p(4p-9)-124p²-9p-12Since, it's one term has power 2, so it is quadratic
The toll to a bridge is 2.50. A three-month pass costs $12.00 and reduces the toll to $0.50. A six month pass $37 and permits crossing the bridge for no additional fee. How many crossing per three month period does it take for the three month pass to be the best deal.
c=number of crossings; Q=quarterly pass; S=semi-annual pass; P=pay as you go
P=$2.50c
Q=$12+$0.50c
S=$40
Compare single pay and quarterly ticket:
$2.50c=$12+$0.50c Subtract $0.50c from each side
$2.00c=$12 Divide each side by $2.
c=6 6 crossings is the break even for single pay and quarterly ticket: more crossings favor the ticket.
Compare quarterly and semi-annual tickets:
3 month pro-rated cost of semi annual ticket=$20
$20=$12+$0.50c Subtract 12 from each side
$8=$0.50c Divide each side by $0.50
16=c The break=even point between quarterly and semi annual tickets is 16 crossings per 3 months. More than this favors the semi annual ticket.
ANSWER: The three month pass is the best deal if you cross between 6 and 16 times during the three month period.

[tex] {5}^{2x - 1} = 12^{x} [/tex]
good luck
use indices nooooo log
step by step explanation:
Add 1 to both sides
52x−1+1=12x+1
Simplify
52x=12x+1
Subtract 12x from both sides
52x−12x=12x+1−12x
Simplify
40x=1
Divide both sides by 40
40x40 =140
Simplify

At a cookware party, 7 of the 25 items are made of glass. What percent of the cookware items are glass?
Answer:
28 %
Step-by-step explanation:
Percentage of glass cookware items = no. of glass cookware items / total no. of cook wares * 100
= 7 / 25 * 100
= 28 %
An electrician charges $40 to come to your house. She also charges $55 for each hour that she works. The electrician charges you a total of $205. How many hours does the electrician work at your house? Use h for the number of hours.
Answer:
$40 + h = $190
190 - 40 = 150
150 ÷ 55 ≈ 2.70 = 3
SO the electrician worked about 3 hours at your house.
h ≈ 3

The diameter of a circle has endpoints (7, 33) and ( 31, 1). Part One: What is the radius of the circle in units?
Answer:
20 units
Step-by-step explanation:
31 - 7 = 24
33 - 1 = 32
24 ^2 + 32^ 2 = c^2
576 + 1024 = c^2
c = 40(diametre)
r = 40÷ 2
= 20 units
I need help with the perimeter
the measurements of a rectangular tablecloth are 94 cm and 64 cm.
how many cm does the perimeter of the tablecloth measure?
how many cm of fabric were used to make it?
Step-by-step explanation:
1) Perimeter = 2(l + w)
Perimeter = 2(94 + 64)
Perimeter= 2(158) = 361 cm
2) Fabric required = Area
Area = l × b
Area = 94 × 64
Area = 6016 cm²
The measurements of a rectangular tablecloth are 94 cm and 64 cm.
Solution and Answer:How many cm does the perimeter of the tablecloth measure?
Perimeter = 2(Length × Width)P = 2(l + w)P = 2(94 + 64)P = 2(158)P = 316 cmTherefore, the perimeter of the tablecloth is 316 cm.
How many cm of fabric were used to make it?
Area = length × widthA = l × wA = 94cm × 64 cmA = 6,016 cm²Therefore, the fabric is 6,016 cm².
The number of writing instruments in some teachers' desks is displayed in the dot plot. Which is greater the mean or the median? Explain your reasoning using the shape of the distribution.
please help..
30 points
The median is greater than the mean. From the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean.
In the given chart we can deduce the following;
number of instruments that is 5 = 1number of instruments that is 6 = 1number of instruments that is 7 = 1number of instruments that is 8 = 1number of instruments that is 9 = 3number of instruments that is 10 = 4number of instruments that is 11 = 2number of instruments that is 12 = 1These numbers can be listed as follows;
5, 6, 7, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 12
The median of these numbers is calculated as;
[tex]median = \frac{9+ 10}{2} = 9.5[/tex]
The mean of these numbers is calculated as;
[tex]mean = \frac{5+6+7+8+9+9+9+10+10+10+10+11+11+12}{14} = 9.07[/tex]
Thus, the median is greater than the mean.
Also, from the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean. But if the distribution is skewed to the right, the mean is always greater than the median.

A dealer mixes 120 liters of milk containing 5% water with 80 liters of milk containing 10 % water. the percentage of water in the mixture is??
9514 1404 393
Answer:
7%
Step-by-step explanation:
Let x represent the percentage of water in the mix. The amount of water in the mix is ...
5%·120 +10%·80 = x·(120 +80)
14/200 = x = 7% . . . . . . . . . . . . . . simplify, divide by 200
The percentage of water in the mixture is 7%.

Step-by-step explanation:
Un cantante subió una publicación la semana pasada en una red social, obtuvo 21 751 "me gusta" y 83 464 "me encanta" por parte de sus fans. Sise sabe que 57 329 de los que participaron en la publicación eran del sexo femenino, ¿cuántas personas eran del sexo masculino? *
A. 46 786 B. 47 886
C. 57 896
D. 57 96
Tenemos que resolver un ejercicio algebraico.
Veremos que la opción correcta es B: 47,886
Lo que sabemos es:
21,751 fans pusieron "me gusta"
83,464 pusieron "me encanta"
Asumimos que cada fan puede usar una sola de esas dos cosas.
Entonces el número total de fans es:
21,751 + 83,464 = 105,215
Tambien sabemos que entre los fans, hay 57,329 mujeres.
Entonces el resto serán hombres:
105,215 - 57,329 = 47,886
Podemos concluir que hay 47,886 hombres, por lo que la opción correcta es B.
