Answer: [tex]x-0.1x=27[/tex]
Step-by-step explanation:
Let x be the number that gets decreased by 10% of itself.
x decreased by 10% of x is 27.
x is 100%, so 100%-10%=90%
So, 90% of x equals 27.
90% = 0.9
0.9x = 27
x = 30
Find the 96th term of the arithmetic
sequence -3, -14, -25,
The 96th term of this arithmetic sequence is -1059.
In an Arithmetic Progression (AP), the nth term is given by the formula-
a9 = a + (n-1)d
where a = first term of the AP
d = common difference
Here, we are given an AP-
-3, -14, -25
Here a = -3
and d = -14 + 3 = -11
Let the 96th term of the AP be a96
Therefore, according to the formula for finding the nth term of an AP, we get-
a96 = a + (96-1)d
a9 = a + 95d
Substituting the values of a and d given in the question-
a96 = -3 + 96(-11)
a96 = -3 - 1056
a96 = -1059
Thus, the 96th term of the arithmetic sequence is -1059.

Write the quadratic equation whose roots are -5 and 3, and whose leading coefficient is 3.
(Use the letter x to represent the variable.)
Answer: (x-3)(x-5) = x2 - 8x + 15
The roots will be unchanged by multiplication by 3: 3x2 - 24x + 45
Step-by-step explanation:
Answer:
y = 3x² + 6x - 45
Step-by-step explanation:
given roots x = a and x = b then the factors are (x - a) and (x - b)
then the quadratic is the product of its factors
y = a(x - a)(x - b) ← a is a multiplier
here x = - 5 and x = 3 with a = 3 , then factors are
(x - (- 5)) and (x - 3) , that is (x + 5) and (x - 3) , then
y = 3(x - 3)(x + 5) ← expand factors using FOIL
y = 3(x² + 2x - 15) ← distribute parenthesis by 3
y = 3x² + 6x - 45

Step-by-step explanation:
The negative exponent automatically makes it smaller than the positive exponent. The more negative the exponent is, the less the value it will be. However, since 1.01 < 2.7, then it is less.

Explain how to find the constant of proportionality for the ratio of robins to cardinals.
Not really sure how this works!! Thank you for all help
The constant of proportionality is 3 for the ratio of robins to cardinals.
We have a table:
Cardinals Robins
5 15
6 18
9 27
10 30
We need to find the constant of proportionality.
The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship.
We know that:
Robins ∝ Cardinals
Robins = K × Cardinals
K = the constant of proportionality
15 = k (5)
k = 3
So, we get the constant of proportionality as 3.
Therefore, the constant of proportionality is 3 for the ratio of robins to cardinals.

What is the binomial?A binomial is defined as a polynomial with two terms.
Examples of binomials are; x − 2 and x − 6 are both binomials.
A) x² - 4x + 2; This is a quadratic function with 3 terms and is therefore a trinomial and not a binomial.

Determine if the conjecture is true or false.
If False give a counterexample.
a = 1, b = 2 is a counterexample, and with that, we conclude that the conjecture is false.
Is the conjecture true or false?Here we have the conjecture:
"For any two integers a and b, (a - b)^2 = (a^2 - b^2)"
Notice that if we find a single pair of integers a and b such that the equality in the conjecture is false, then we have found a counterexample and that is enough to conclude that the conjecture is false.
If we define=
a = 1
b = 2
Replacing that in the equation of the conjecture we get:
(1 - 2)^2 = (1^2 - 2^2)
(-1)^2 = 1 - 4
1 = -3
This is false, then a = 1, b = 2 is a counterexample, and with that we conclude that the conjecture is false.

seconds.
After 156 seconds the strands will change color at the same time again.
As strand 1 changes color every 12 seconds and Strand 2 .changes color every 13 seconds. we are provided that both strands just changed color and we need to find that After how many seconds will the strands change color at the same time again
To know After how many seconds will the strands change color at the same time again we need to find the least common multiple (LCM) of 12 second and thirteen seconds
The factors of 12 = 2*2*3
The factors of 13 = 1 *13
LCM =2 * 2* 3*13 = 156
Hence, After 156 seconds the strands will change color at the same time again

which of the following indicates the division property of equality when solving -12x = 48
From division it is possible to find x= -4.
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=7x+2. Where:
a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex] .
b= the constant term that represents the y-intercept.
For the given example: a=7 and b=2.
For solving linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.
Therefore for -12x=48, you should follow the steps below
-12x=48
x=48/ (-12)
x= -4
