Answer:
Step-by-step explanation:
-9x +15y = 3(-3x +5y) = -3(3x - 5y)
The required equivalent expression for the given expression -9x + 15y is 3(-3x + 5y).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
The given expression is given as follows:
-9x + 15y
It is required to find the factorization of the given expression.
As per the question, we have
-9x + 15y
To factor -9x + 15y, we can first factor out the greatest common factor (GCF) of -9 and 15, which is 3:
-9x + 15y = 3(-3x + 5y)
Therefore, the equivalent expression for -9x + 15y is 3(-3x + 5y).

Rowena’s monthly gasoline bill dropped from $83.75 last month to $56.95 this month. Find the percent decrease.
Round your answer to the nearest percent.
Do NOT round until you have calculated the final answer.
Answer:
The percent decrease was of 32%.
Step-by-step explanation:
The percent decrease is the decrease multiplied by 100, and divided by the initial value.
Rowena’s monthly gasoline bill dropped from $83.75 last month to $56.95 this month.
So a decrease of 83.75 - 56.95 = $26.80
Percent decrease:
26.80*100/83.75 = 32%
The percent decrease was of 32%.

Why doesn't the SSA triplet guarantee triangle congruence?
Answer: Because Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two different places. Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles.The AS.S Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. If two triangles have two congruent sides and a congruent non included angle, then triangles are NOT NECESSARILY congruent. And The SSA (or AS.S) combination deals with two sides and the non-included angle. This combination is humorously referred to as the "Donkey Theorem". SS.A (or AS.S) is NOT a universal method to prove triangles congruent since it cannot guarantee that the shapes of the triangles formed will always be the same.

A fair dice has six sides, numbered 1 to 6
After it is rolled, five of the numbers can be seen.
a) Write down the probability that one of these five numbers is 3
b) Work out the least possible sum of the five numbers
(a). The probability that one of these five numbers is 3 is [tex]\frac{5}{6}[/tex].
(b). The least possible sum of the five numbers is 15
Probability:Probability is the ratio of number of favourable outcomes to the total number of outcomes.
When a fair dice has six sides, numbered 1 to 6 ,After it is rolled, five of the numbers can be seen.
The probability that one of these five numbers is 3 is computed as,
[tex]P(E)=\frac{5}{6}[/tex]
The least possible sum of the five numbers, when the number 6 is hidden.
Least sum = 1 + 2 + 3 + 4 + 5 = 15

the triangle Loom is made from wood strips shaped into a 45 45 90 triangle. pegs are placed every half inch along the hypotenuse and every quarter inch along each leg. suppose you make a loom with an 18 inch hypotenuse. approximately how many pegs will you need
Answer:
36 pegs (for the hypotenuse)
About 51 pegs (for the legs)
138 pegs (total)
Step-by-step explanation:
Along the hypotenuse, the pegs are placed every half-inch. That would make 2 pegs per inch. Multiply 2 x 18 to get 36.
The legs are each 9 sqrt 2. This is 12.7279220614. The pegs are placed at each quarter inch for the legs. This is 4 per inch. So multiply 12.7279220614 x 4 to get 50.9116882454. Round this to 51.
Add 51 + 51 for the legs total pegs. You get 102. Add 102 + 36 to get 138 pegs total.

Calculate the distance between the points J=(4, -2) and E = (7. – 7) in the coordinate plane.
Give an exact answer (not a decimal approximation).
Answer:
Step-by-step explanation:
√[(7-4)^2+{-7-(-2))^2] = √36 = 6
The distance between the points J=(4, -2) and E = (7. – 7) in the coordinate plane is 6.
What is coordinate plane ?"A coordinate plane is a two-dimensional plane formed by the intersection of two number lines. One of these number lines is a horizontal number line called the x-axis and the other number line is a vertical number line called the y-axis. These two number lines intersect each other perpendicularly and form the coordinate plane.
The plane is called two-dimensional because anywhere on this plane where you can put your finger, the location of that point will need two things– its distance on the x-axis and its distance on the y-axis."
Using the distance formula between the points
Given, J = (4,-2) and E = (7,-7)
Distance formula = [tex]\sqrt((x1 - x2)^2 -(y1 - y2)^2)[/tex]
[tex]= \sqrt((4-7)^2 + (-2 - (-7))^2)\\\\= \sqrt(9 + 25) = 6[/tex]
Hence, distance between the points J and E = 6
