- 10x = 5x^2-1
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

What is the solution to the equation 3x + 2(x − 9) = 8x + x − 14? (5 points)
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.
x=-1
Payton goes shopping. She finds two shirts. One costs $24.97 and the other costs $13.75. She needs to
know if she has enough money to buy both shirts. Using mental math, she rounds $24.97 to $25.00 and
adds that to $13.75 to get $38.75. How does Payton need to compensate to find the exact total of the two
shirts?
O A. Subtract $0.03.
B. Add $0.03.
O C. Add $0.25.
OD. Subtract $0.28.
Answer:
A subtract 0.03
Step-by-step explanation:
This is because when she rounded $24.97 to $25.00 she added $0.03 cents so she needs to subtract that amount to get the exact number.

3(-X+4)=7x-8. Yeahhhh...
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]

1. Find the slope of the line containing the points (9,6) (11,9).
Answer:
[tex]y=\frac{3}{2}x-\frac{15}{2}[/tex]
Step-by-step explanation:
Use the point-slope formula [tex]y-y_{1}=m(x-x_{1})[/tex]
First you have to find m with the formula [tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
[tex]m = \frac{9 - 6}{11 - 9} = \frac{3}{2}[/tex]
Choose whichever point you want as [tex](x_{1}, y_{1})[/tex], in this case I'll choose [tex](9, 6)[/tex]
[tex]y - y_{1} = m(x - x_{1})\\y - 6 = \frac{3}{2} (x - 9)\\y - 6 = \frac{3}{2}x - \frac{27}{2} \\y = \frac{3}{2}x - \frac{27}{2} + 6\\y = \frac{3}{2}x - \frac{15}{2}[/tex]
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
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
What x value makes this equation true -12x - 2(x+9) = 5(x+4)
A. -2
B. 13/19
C. 5
D. -1/3
Answer:
A. -2, x= -2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Given
- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides )
- 12x - 2x - 18 = 5x + 20 , that is
- 14x - 18 = 5x + 20 ( subtract 5x from both sides )
- 19x - 18 = 20 ( add 18 to both sides )
- 19x = 38 ( divide both sides by - 19 )
x = - 2 → A

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]

¿Cuál es el valor de 0.1561 redondeado a la décima más cercana?
A 0.15
B 0.16
C 0.1
D 0.2
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

A map has a scale of 1 inch : 5 kilometers. Use the given actual distance to find the map distance.
14.4 inches
9.25 inches
68 inches
20.3 inches
Answer:
A) inches: 1.5, 1.2, 3.0, 3.9
B) km 72, 46.25, 340, 101.5
Step-by-step explanation:
A) To find the distance in inches, divide by 10 miles:
15 miles ⇒ 1.5 inches
12 miles ⇒ 1.2 inches
30 miles ⇒ 3.0 inches
39 miles ⇒ 3.9 inches
__
B) To find the distance in km, multiply the map distance by 5.
14.4 in ⇒ 72 km
9.25 in ⇒ 46.25 km
68 in ⇒ 340 km
20.3 in ⇒ 101.5 km
