Lana uses factoring by grouping to factor the polynomial 8x2y−10xy2+12x−15y. Her work follows, but the last two lines of work are missing.
Which answers correctly fill in the blanks?
Select two answers: one for blank 1 and one for blank 2.
Answers
Answer:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)
Step-by-step explanation:
The first step in factoring this polynomial is to find the biggest common factor in both numbers inside the parenthesis, and the second step is to find the biggest common factor of the 2 addents.
The other steps are invalid, either because they don't respect positive or negative signs, or that they just factor it wrong completely.
The only correct answer are:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)

What are the slope and the y-intercept of the line shown in the graph?
A. y-intercept = 2 and slope = -3
B. y-intercept = 2 and slope = 3
C. y-intercept = 3 and slope = 2
D. y-intercept = -3 and slope = 2
Answers
Answer:
A
Step-by-step explanation:
The y intercept is where the line crosses the Y (vertical) axis. In this case, it happens at y=2
The slope is the rate of change. For every 1 space it moves on the horizontal axis, it moves 3 vertical spaces. It is going down, so it is -3

2. Tina uSUally brings her children every Sunday afternoon at the children's park in their barangay. The park is 350m Iong and 200m wide complete with slides and
swings for children to play. If is surounded by a pathway of unifom width for children who loves biking and jogging. Suppose the total area of the park and the pathway is 74,464 m2.
a. How wide is the pathway of the park?
b. If you were Tina, woulad you like your children fo go biking and jogging in that park?
Answers
Answer: kindly check explanation
Step-by-step explanation:
Given the following :
Total area of parknand path way = 74,464 m2.
Dimension of park = 350m by 200m
Using the area of rectangle formula:
Area = Length * width
Area of park = 350m * 200m
Area of park = 70,000
Area of path = (74,464 - 70,000) = 4,464m2
Since path has uniform width, then width of the the path is sqrt(4464) = 66.8m
2.) the path of the park seems a bit narrow, hence, I wouldn't love children to bike and jog in such a narrow path

What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
As, slope for printer A= 30-2/2-0
= 30/2 = 15 pages per minute.
So, the rate of Printer A is 15 pages per minute.
Thus,
The rate for Printer B is greater than the rate for Printer A because the rate of 25 pages per minute is greater than the rate of 15 pages per minute for Printer A.

A. 36/9 yards
B. 37/9 yards
C. 35/9 yards
D. 38/9 yards
Answers
Answer:
No estoy seguro, intenta preguntarle a tu profesor
Step-by-step explanation:
The seamstress had 37/9 yards of material for each uniform.
What is division?In mathematics, division is a process of dividing a number into equal parts and calculating the maximum number of equal parts that can be made.
How to solve it?Given that total amount of material = 148 yards
number of students in the concert band = 16
number of students in the symphonic band = 20
Total number of students = number of students in the concert band + number of students in the symphonic band
= 16 + 20 = 36
For 36 students, there are 148 yards of material.
Then for 1 student, there are 148/36 = 37/9 yards of material.
Therefore the seamstress had 37/9 yards of material for each uniform. So, option B is correct.

m∠YPQ = 159°
Step-by-step explanation:
m∠QRP = 107
m∠RQP = 52
m∠RPQ = x
m∠QRP + m∠RQP + m∠RPQ = 180°
107 + 52 + x = 180
159 + x = 180
x = 21°
m∠RPQ = x = 21°
m∠RPQ + m∠YPQ = 180°
21° + m∠YPQ = 180°

larry gets a 5% wage rise. his new wage is £252 per week. what was larrys wage before his wage rise
Answers
The raise was 5% which is 0.05 as a decimal.
For his new rate his original rate was multiplied by 1.05 ( original + 5%)
To find original amount, divide new amount by 1.05:
252 / 1.05 = 240
His original pay was £240
You can check by multiplying the original pay by 5% and adding:
240 x 0.05 = 12
240 + 12 = 252

Which statement or statements accurately describe a good way to avoid excessive service fees?
1. Try to deposit money in large batches rather than in small amounts.
II. Try to limit the number of withdrawals you make from out-of-network ATMs.
III. Try to avoid using your debit card online.
a. I and II
b. ll only
c. Ill only
d. I and III
Answers
Answer:
b. ll only
Explanation:
Remember, service fees often refer to an amount deducted to pay for the cost of providing particular services, such as ATM service charges, etc.
We can this conclusion because if one decides to deposit money in large batches rather than in small amounts; they will be directly subjecting themselves to excessive charges. Consider, most financial institutions often charge higher fees for larger deposits.
Also, if one decides to avoid using your debit card online they will tend to spend more using traditional cash methods which require increasing the number of one's ATM withdrawal.
However, by trying to limit the number of withdrawals you make from out-of-network ATMs, one saves him or herself of excessive service fees.

x = −5 and x = 5
x = −4 and x = 4

Answer:
x=-1 and x=9
Step-by-step explanation:
[tex]3(x-4)^{2} =75[/tex]
[tex](x-4)^{2} =\frac{75}{3}[/tex]
[tex](x-4)^{2}[/tex]=[tex]25[/tex]
