2. Find 2 solutions to -X > 10
The two solutions of the inequality -X > 10 are -15 and -11
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
To solve the inequality -X > 10, we need to isolate the variable X on one side of the inequality.
We can start by multiplying both sides of the inequality by -1 to get:
X < -10
This means that any value of X that is less than -10 will satisfy the inequality.
Therefore, two possible solutions to the inequality are:
X = -15 (since -15 is less than -10, the inequality -X > 10 is true)
X = -11 (since -11 is also less than -10, the inequality -X > 10 is true)
Note that there are infinitely many possible solutions to the inequality, since any value of X that is less than -10 will work.
Hence, the two solutions of the inequality -X > 10 are -15 and -11

BRAINLEST! Madison determined that the function f(x)=3x+24 represents the cost of texting on her current cell phone plan, where x represents the number of texts. She discovers that using the inverse function to solve for x = 36, she can predict the how many texts she can use for $36. Explain to Madison how to accomplish this, using complete sentences. You may show any algebraic work necessary to support your explanation.
Answer:
Step-by-step explanation:
Start with f(x)=3x+24 and find the inverse function:
1. Replace "f(x)" with y: y = 3x + 24
2. Interchange x and y: x = 3y + 24
3. Solve for y: 3y = x - 24, or y = (1/3)(x - 24)
This last step results in the inverse function.
Now let's test this. Let x = 36. How many texts could Madison "do" for this dollar amount? y = (1/3)(36 - 24) results in y = (1/3)(12), or 4 (texts).
Let's go back to the original f(x)=3x+24, now letting x = 4:
f(x)=3(12)+24 = $36. This verifies that y = (1/3)(x - 24) is the inverse function of f(x) = 3x + 24.
What are the solutions of x^2 - 2x +2 = 0?
A. X= i Or x= -i
OB. X= 2+ i or x = 2- I
O C. x = 1+i or x = 1-i
O D. x = 2i or x = -2i
Answer:
C
Step-by-step explanation:
Given
x² - 2x + 2 = 0 ( subtract 2 from both sides )
x² - 2x = - 2
To solve use the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(- 1)x + 1 = - 2 + 1
(x - 1)² = - 1 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{-1}[/tex] = ± i ( add 1 to both sides )
x = 1 ± i , then
x = 1 + i or x = 1 - i → C
What is the result of subtracting a number greater than -3 and less than -2 from a number greater than 1 and less than 6
Answer:
3 < M - N < 9
Step-by-step explanation:
First, let's write the inequalities for these two numbers.
"a number greater than -3 and less than -2"
-3 < N < -2
"a number greater than 1 and less than 6"
1 < M < 6
We want to subtract the first one to the second one, so we want to get:
M - N
Because this is a subtraction, the lower bound of the subtraction happens when we have the minimum value of M and the maximum value of N.
Then the minimum value of M - N happens when:
M = 1
N = -2
(notice that M can't be equal to 1, and N can't be equal to -2, we just do this to find the lower bound)
Then the lower bound is:
M - N = 1 - (-2) = 3
We already got:
3 < M - N
For the upper bound, we need to find the difference between the largest value of M, and the lowest value of N
This is:
M = 6
N = -3
M - N = 6 - (-3) = 9
Then:
M - N < 9
If we take both of our results, the possible values of the subtraction are given by:
3 < M - N < 9
The result of subtracting a number greater than -3 and less than -2 from a number greater than 1 and less than 6 is mathematically given as
3 < M - N < 9
What is the result of subtracting a number greater than -3 and less than -2 from a number greater than 1 and less than 6Question Parameter(s):
-3 < N < -2
1 < M < 6
therefore,
subtraction for lower bound
M - N = 1 - (-2)
M - N = 3
3 < M - N
subtraction for upper bound
M - N = 6 - (-3)
M - N = 9
M - N < 9
In conclusion, the possible values after subtraction are
3 < M - N < 9

Un inversionista coloca 1.000.000 en un banco durante un año a una tasa de interés del 16% capitalizable mensualmente. ¿Cual es la tasa efectiva?
Answer:
Tasa efectiva anual= 0.1722= 17.22%
Step-by-step explanation:
Dada la siguiente información:
Tasa de interes anual= 16% capitalizable mensualmente
Primero, debemos calcular la tasa nominal mensual:
Tasa mensual= 0.16 / 12= 0.01333
Ahora, usando la siguiente formula, la tasa efectiva anual:
Tasa efectiva anual= (1 + i)^n - 1
Tasa efectiva anual= (1.01333^12) - 1
Tasa efectiva anual= 0.1722= 17.22%

Answer:
D. 16 times.
Step-by-step explanation:
Volume of a cylinder = π r^2 h
π r^2 h = 432
Now if the diameter is reduced by 1/4 then the radius is reduced by a fourth also.
Let the new height be H, then:
432 = π (r/4)^2 H
so π r^2 h = π(r/4)^2 H
r^2 h = r^2 H / 16
h = H/16
H = 16h.

The given point (-3, -9) is reflected over X-axis
Answer:
The correct answer is (3, 9)
Step-by-step explanation:
The rule for reflecting over the X-axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X-axis and mapped onto point P', the coordinates of P' are (5,-4).

c Find the area of this rectangle
M
Step-by-step explanation:
Given that,
Length, l = (3d+2) m
Width, b = (d+5) m
(a) Perimeter of the rectangle,
P = 2(l+b)
P = 2(3d+2+d+5)

b = (2+5) = 7 m
The area of this rectangle,
A = lb
A = 8×7
A = 56 cm²
Hence, this is the required solution.

At the candy store there are 1170 candies: 1080 gumdrops and 90 chocolate bars. What is the ratio of candies to chocolate bars?
Answer: 13:1
Step-by-step explanation:
Number of candies = 1170
Number of gumdrops = 1080
Number of chocolate bars = 90
The ratio of candies to chocolate bars will be calculated thus:
= Number of candies / Number of chocolate bars
= 1170 / 90
= 13/1
= 13:1
Therefore, the ratio of candies to chocolate bars is 13:1.

Use the quadratic formula to solve 2^2 − 5 − 5 = 0
The formula is : ( -b ± √b^2 - 4ac ) / 2a
Answer:
x = 5/4 + √65/4 or x = 5/4 - √65/4
Step-by-step explanation:
I'm assuming you mean 2x^2-5x-5=0?
x = ( -b ± √b^2 - 4ac ) / 2a
x = ( -(-5) ± √(-5)^2 - 4(2)(-5) ) / 2(2)
x = ( 5 ± √(25 + 40) ) / 4
x = ( 5 ± √65 ) / 4
x = 5/4 ± √65/4
Therefore, x = 5/4 + √65/4 or x = 5/4 - √65/4
