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)

The basketball gym at Dustin's school was built in the 1940s and needs a lot of repairs. So, the school is asking families for donations to build a new gym. Dustin convinced some local businesses to match a fraction of the families' donations. There is a proportional relationship between the amount of money a family donates (in dollars), x, and the matching contribution (in dollars) from local businesses, y. When a family donates $12, the businesses contribute $9. Write the equation for the relationship between x and y.
Answers
Answer:
The equation representing the relationship between x and y is that;
4y = 3x
Step-by-step explanation:
Here, we want to write a relationship.
From the question, we are told that the amount donated by the family which is x dollars is proportional to what local businesses gave.
From the question, there was an example in which a family gave $12 and local businesses gave $9
So let us establish a relationship using ratio of x to y
Thus;
12/9 = x/y
12y = 9x
4y = 3x

Huang Yi works as a paleontologist and a sculptor. She earns \$5{,}500$5,500dollar sign, 5, comma, 500 per month as a paleontologist and \$4{,}500$4,500dollar sign, 4, comma, 500 per month as a sculptor. Huang Yi wants to make more than \$50{,}000$50,000dollar sign, 50, comma, 000 this year. In the inequality shown above, PPP represents the number of months Huang Yi can work as a paleontologist and SSS represents the number of months she can work as a sculptor to reach her goal. If Huang Yi worked for 666 months as a paleontologist this year, what is the minimum whole number of months that she must work as a sculptor to reach her goal?
Answers
Answer:
4 months
Step-by-step explanation:
Let P represents the number of months Huang Yi can work as a paleontologist and S represents the number of months she can work as a sculptor to reach her goal.
If she works for P months as an paleontologist, her income would be 5500P while if she works for S months as a sculptor her income would be 4500S.
Her total income = 5500P + 4500S
Since she wants to earn more than $50000, hence:
5500P + 4500S > 50000
Given she worked as a paleontologist for 6 months, therefore:
5500(6) + 4500S > 50000
33000 + 4500S > 50000
4500S > 50000 - 33000
4500S > 17000
S > 17000/4500
S > 3.78
S > 4
The minimum whole number of months that she must work as a sculptor to reach her goal is 4 months

Solve for x if 5x + 2(x - 3) = 7x - 6
Help me plsss
Answers
Answer:
x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x + 29 (x − 3) = 7x − 6
5x + (29) (x) + (29) (−3) = 7x + −6 (Distribute)
5x + 29x + −87 = 7x + −6
(5x + 29x) + (−87) = 7x − 6 (Combine Like Terms)
34x + −87 = 7x − 6
34x − 87 = 7x − 6
Step 2: Subtract 7x from both sides.
34x − 87 −7x = 7x −6 −7x
27x − 87 = −6
Step 3: Add 87 to both sides.
27x − 87 + 87 = −6 + 87
27x = 81
Step 4: Divide both sides by 27.
27x/27 = 81/27
x = 3

Evaluate the expression m +(3n - 5)2 when m = 6 and n = 4.

Answer: 55
Step-by-step explanation:
M + (3n - 5)² = 6 + (3 x 4 – 5)^²
* 6 + (7)²
* 6 + 49 = 55
Sorry if the other answer misleads you. Here is the real answer!
The answer to the expression m +(3n - 5)² is 55.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
m +(3n - 5)²
Now, put the value of m= 6 and n= 4 we get
m +(3n - 5)²
= 6 +(3(4) - 5)²
= 6 +(12 - 5)²
= 6 +(7)²
= 6+ 49
= 55
Hence, the answer is 55.

Which function represents the same relationship?
Answers
Answer:
y=-3x-10.5
Step-by-step explanation:
Let's use the first set of numbers.
-7.5 and 12
-3.5 and 0
Our rise here is -12 and run is 4. So, our slope is -3.
Now we just need our intercept.
y = mx + b
y = -3x + b
0 = -3(3.5) + b
b = -10.5
The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.
What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

The table represents some points on the graph of a linear function.

-3.5 0
-1 -7.5
2 -16.5
3.5 -21
Take two points from the table, then the points are (-7.5, 12) and (-3.5, 0). Then the equation of the line is given as,
y - 0 = [(-3.5 + 7.5) / (0 - 12)](x + 3.5)
y = - (1/3)(x + 3.5)
3y = - x - 3.5
x + 3y + 3.5 = 0
The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.
