2t-✓2= 3t+✓2. Number 1
(-x+2✓3)(-3x-✓2) =0 number 2
Answer:
which class you read now
Answer:
see explanation
Step-by-step explanation:
Given
2t - [tex]\sqrt{2}[/tex] = 3t + [tex]\sqrt{2}[/tex] ( add [tex]\sqrt{2}[/tex] to both sides )
2t = 3t + 2[tex]\sqrt{2}[/tex] ( subtract 3t from both sides )
- t = 2[tex]\sqrt{2}[/tex] ( multiply both sides by - 1 )
t = - 2[tex]\sqrt{2}[/tex]
-----------------------------------------------------------
Given
(- x + 2[tex]\sqrt{3}[/tex] )(- 3x - [tex]\sqrt{2}[/tex] ) = 0
Equate each factor to zero and solve for x
- x + 2[tex]\sqrt{3}[/tex] = 0 ( subtract 2[tex]\sqrt{3}[/tex] from both sides )
- x = - 2[tex]\sqrt{3}[/tex] ( multiply both sides by - 1 )
x = 2[tex]\sqrt{3}[/tex]
- 3x - [tex]\sqrt{2}[/tex] = 0 ( add [tex]\sqrt{2}[/tex] to both sides )
- 3x = [tex]\sqrt{2}[/tex] ( divide both sides by - 3 )
x = - [tex]\frac{\sqrt{2} }{3}[/tex]

A line with a slope of -2 passes through the points (-4, 7) and
(0, n). What is the value of n?
Answer:
n = -1
Step-by-step explanation:
Use the equation y=mx + b
m (slope) = -2
x (x coordinate) = -4
y (y coordinate) = 7
You are solving for b.
Plug in for the given values:
7 = -2(-4) + b
7 = 8 + b
-1 = b (Minus both sides by 8)
y= -2x -1
Therefore, n = -1

n/9 + 2/3 = -2/3
Answer:
n = - 12
Step-by-step explanation:
n/9 + 2/3 = - 2/3
n/9 = - 2/3 - 2/3
n/9 = - 4/3
n = 9(- 4/3)
n = -36/3
n = - 12

Answer:
A
Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].
To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!

$1147.50
$5647.50
$11,475
$95.63
RIGHT ANSWER BRAINLYEST
Answer:
$5647.50
Step-by-step explanation:
Formula for interest => I = Prt
substitute => I = (4500)(0.085)(3)
I = 1147.5
Add interest to our principle value => 4500 + 1147.5
Thus, our answer: $5647.50

Answer:
B and D are correct.
Step-by-step explanation:
To find the area of a rectangle, simply multiply its length by its width. In this case, the length of the rectangle is [tex]5[/tex] m and the width of the rectangle is [tex]3[/tex] m, so its area must be [tex]5*3=15[/tex] square meters.
To find the area of a triangle, divide the product of the triangle's base and height by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] and [tex]h[/tex] are the triangle's base and height, respectively. In this case, [tex]b=6[/tex] and [tex]h=5[/tex], so the triangle's area is [tex]\frac{6*5}{2}=15[/tex] square meters.
Now, let's look at the statements.
A: The triangle's area is [tex]15[/tex] square meters, not [tex]30[/tex], so A is incorrect.
B: The rectangle's area is [tex]15[/tex] square meters and the triangle's area is also [tex]15[/tex] square meters. Because the two figures have the same areas, their areas are equal, so B is correct.
C: We've already established that the two figures have equal areas, so one can't have a greater area than the other. Therefore, C is incorrect.
D: The rectangle's area is indeed [tex]15[/tex] square meters, so D is correct.
Hope this helps!
Answer:
B is correct, and D is correct
if you multiply 3 times 5 you get 15 m which is the area for the rectangle, then you have to find the area for the triangle, which you would have to multiply 6 times 5 which you get 30, then divide 30 by 2, which would be 15!

Camilo compró un auto usado en $6,000.000y aceptó pagar $1,000.000 al contado y $1,000.000 al mes con interés del 6% anual sobre saldos insolutos. ¿Cuál será el pago total que realizará Camilo?
Answer:
El pago total que hará Camilo es $6,150,000
Step-by-step explanation:
La cantidad que Camilo compró el auto usado = $6,000,000
La cantidad que Camilo acordó pagar en efectivo = $1,000,000
La cantidad que pagará Camilo en un mes = $1,000,000
El interés sobre el saldo impago = 6%
Por lo tanto, tenemos;
El interés sobre el saldo en un año = 6/100 × 5,000,000 = 300,000
El interés por mes = 300.000 / 12 = 25.000
La cantidad de meses que Camilo paga el saldo de 5,000,000 a 1,000,000 por mes = 5,000,000 / 1,000,000 mes = 5 meses
El momento en que paga el saldo restante = El sexto mes
La cantidad de interés pagado en los seis meses = 25,000 × 6 = 150,000
El pago total que hará Camilo, A = 6,000,000 + 150,000 = 6,150,000
El pago total que hará Camilo, A = $6,150,000

Please answer this as soon as possible thank you I appreciate it
Answer:
a. Yes
Step-by-step explanation:
Plug the values into each expression to check
y - 3 = x
4 - 3 = 1
1 = 1
This checks out
2y = 2x + 6
2(4) = 2(1) + 6
8 = 2 + 6
8 = 8
This checks out so the coordinates do indeed satisify the equations
PLZ HELP!!! I'M BEGGING YOU!!! A hero is fighting with a dragon. At first, the dragon has three heads but each time the hero chops off a head the dragon grows three in its place. How many heads does the dragon have after n chops?
Answer:
n = 3x
Step-by-step explanation:
Answer:
h(n) = 3 + 2nStep-by-step explanation:
Initial number of heads is 3Each chopped head is replaced with 3 headsLet the number of chops is n and h(n) is the number of heads.
After the first chop and consecutive chops the number of heads are:
h(1) = 3 - 1 + 3 = 3 + 2*1h(2) = 3 + 2 - 1 + 3 = 3 + 2*2h(3) = 3 + 2*2 -1 + 3 = 3 + 2*3...h(n) = 3 + 2n5

Parallelogram FGHJ was dilated and translated to form similar parallelogram F'G'H'J'. What is the scale factor of the dilation?
Answer:
The scale factor is 4
Step-by-step explanation:
Given
See attachment for parallelograms
Required
Determine the scale factor (k)
Using sides FG and F'G' as a point of reference:
[tex]FG = 2\ units[/tex]
[tex]F'G' = 8\ units[/tex]
The scale factor (k) is calculated as:
[tex]k = \frac{New}{Original}[/tex]
[tex]k = \frac{F'G'}{FG}[/tex]
[tex]k = \frac{8\ units}{2\ units}[/tex]
[tex]k = 4[/tex]

Kalyan's present age is one third his mothers present age . If the mothers age was 5 times his age 6 years ago ,what are their present age
Current ages:
Let Kaylan's present age be x years
Since his age is a third of his mother's present age:
mother's age * (1/3) = Kaylan's age
mother's age * (1/3) = x
mother's age = 3x [multiplying both sides by 3]
Kaylan's mother's age would be 3x years
Their ages 6 years ago:
Kaylan's age: x-6 years
Mother's age: 3x-6 years
We are told that mother's age was 5 times Kaylan's age, 6 years ago. So,
5*(Kaylan's age 6 years ago) = (Mother's age 6 years ago)
replacing the values
5(x - 6) = 3x-6
5x - 30 = 3x-6
2x - 30 = -6 [subtracting 3x from both sides]
2x = 24 [adding 30 on both sides]
x = 12 [dividing both sides by 2]
Hence, x = 12
Kaylan's present age(x) = 12 years
Mother's present age(3x) = 3*12 = 36 years

what is 2/10 divided by 2/4
Given:
[tex]\dfrac{2}{10}[/tex] divded by [tex]\dfrac{2}{4}[/tex].
To find:
The solution for the given division problem.
Solution:
We have, [tex]\dfrac{2}{10}[/tex] divded by [tex]\dfrac{2}{4}[/tex]. It can be written as
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}[/tex]
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}[/tex]
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}[/tex]
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}[/tex]
Therefore, the solution for the given division problem is [tex]\dfrac{2}{5}[/tex].
