WILL DO BRAINLIEST IF RIGHT ASAP Evaluate the expression for r = –2. –40(–31 − 16r)2 + r2 =
Answers
Answer: -36
Step-by-step explanation:
To evaluate the expression, you want to plug in r to solve.
-40(-31-16(-2))²+(-2)² [parenthesis]
-40(1)²+(-2)² [exponent]
-40+4 [add]
-36
Now we know the expression is equal to -36 when r=-2.

- 10x = 5x^2-1
Answers
Answer:
x = (√6/√5) - 1
Step-by-step explanation:
- 10 x = 5x^2 -1
can be written as
5x² + 10x - 1 = 0
completing the square method :
for quadratic equation of the format ax² + bx + c = 0 ,
step 1, divide equation by a
therefore. dividing the equation by 5
=> x² + 2x - (1/5) = 0
=> x² + 2x = 1/5
c - 2b/4 = -1/5 - (2(2)/4) = -(6/5)
b/2 = 1
=> x² + 2x +1 = 6/5
=> (x + 1)² = 6/5
=> x = (√6/√5) - 1

Hey there!☺
[tex]Answer:\boxed{x=2}[/tex]
[tex]Explanation:[/tex]
[tex]3(-x+4)=7x-8[/tex]
Let's start by simplifying both sides. First, we distribute.
[tex](3)(-x)+(3)(4)=7x+-8[/tex]
[tex]-3x+12=7x+-8[/tex]
[tex]-3x+12=7x-8[/tex]
Now let's subtract 7x from both sides.
[tex]-3x+12-7x=7x-8-7x\\-10x+12=-8[/tex]
Now we will subtract 12 from both sides.
[tex]-10x+12-12=-8-12\\-10x=-20[/tex]
In our last/final step, we will divide both sides by -10.
[tex]\frac{-10x}{-10}=\frac{-20}{-10}[/tex]
Now simplify -20/-10.
[tex]-20/-10=2[/tex]
[tex]x=2[/tex]

inequality.
Answers
Answer:
Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.
Step-by-step explanation:
The given inequality is 3b + 8 ≥ 14
We need to solve the given inequality
Step 1.
Subtract 8 to the both sides of the inequality
3b + 8 - 8 ≥ 14 -8
3b ≥ 6
Dividing both sides by 3
b ≥ 2
The value of b is greater than and equal to 2.
Hence, the correct option is (a).

Answers
Answer:
x= -1
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
3x+2(x-9)=8x+x-14 ;; equation
simplify the equation to the form
3x+2(x-9)=8x+x-14
reorder the terms in parentheses
3x+(+2x-18)=8x+x-14
remove unnecessary parentheses
+3x+2x-18=+8x+x-14
move all terms containing x to the left and all other terms to the right.
+3x+2x-8x-1x=-14+18
simplify left and right side of the equation.
-4x=+4
divide both sides of the equation by -4 to get x.

A box contains 7 red, 14 yellow, 21 green, 42 blue, and 84 purple marbles. A marble is drawn at random from the box. Find the odds against drawing a purple or yellow marble.
A. 5 to 7
B. 5 to 12
C. 2 to 7
Answers
Answer:
B
Step-by-step explanation:
Here, we are to find the odds against drawing a purple or yellow marble.
Mathematically, the odds against drawing a particular marble color = 1 - the probability of drawing that particular marble color
probability of drawing a purple colored marble = number of purple colored marbles/total number of marbles
= 84/(84 + 42 + 21 + 14 + 7) = 84/168 = 1/2
So the odds against drawing a purple colored marble = 1 - 1/2 = 1/2
The odds against drawing a yellow marble color = 1 - probability of drawing a yellow colored marble
Probability of drawing a yellow colored marble = number of yellow marbles/total number of marbles = 14/168 = 1/12
So the probability of drawing a yellow colored marble or purple colored marble = 1/12 + 1/2 = 7/12
Now, the odds against drawing either of the two = 1 - the probability of drawing either of the 2 = 1 -7/12 = 5/12
or simply put 5 to 12

Paul wants to estimate the mean number of siblings for each student in his school. He records the number of siblings for each of 100 randomly selected students in the school. What is the parameter?
Answers
Answer:
A parameter is defined as a numerical or another measurable factor that conforms a set that defines a given system.
In this case, the only parameter that we have is the number of siblings that each one of the 100 students has.
For example, in a table:
#student #siblings.
1 3
2 1
3 4
... ...
In the left side, we have the "number of the student" that does not really matter, because the students are randomly selected, and at the right, we can see our only parameter in this study, that is the number of siblings that each student has.

on a number line, point D is located at 9 and point P is located at -11 what is the distance from d to p
Answers
Answer:
20
Step-by-step explanation:
The distance between two points on the number line is the absolute value of the difference of their coordinates.
coordinate of point D: 9
coordinate of point P: -11
Take the absolute value of their difference. It does not make a difference in which order you subtract the coordinates.
distance = |-11 - 9| = |-20| = 20
Answer: The distance is 20.
¿Cuál es el valor de 0.1561 redondeado a la décima más cercana?

D 0.2
Answers
Answer: 0.2
Step-by-step explanation: Necesitamos ajustar la estimación de 0.1561 al décimo más cercano.
El número después del decimal es el número en el décimo lugar. Considere el número a un lado del lugar de las décimas y utilice el número para decidir si se reunirán o seguirán siendo el equivalente. Observe que el número a un lado del décimo lugar es mayor o equivalente a 5 o menos de 5. En el caso de que ese número sea más digno de mención o equivalente a 5, en ese punto el número se reunirá aún en la remota posibilidad de que ese número es menor de 5, en ese momento el número no se reunirá. Permanecerá igual.
Consideremos el número dado 0.1561
El número en el lugar de las décimas es 1
El número después del punto de las décimas es 5 (que es más prominente o equivalente a 5)
De esta manera, el número se reunirá en 0,2
