a is ( 2,-2 )

Answer:

We have that the sum of two numbers  is 9

this can be written as:

x + y  = 9

where x is the larger number.

Now we want to write:

"the difference between one more than the larger number and twice the smaller number"

First, remember that the difference between A and B is:

A - B

Then "the difference between one more than the larger number and twice the smaller number"

is:

"one more than the larger number" = ( x + 1)

"twice the smaller number" = 2*y

the difference between these is:

(x + 1) - 2*y

Now we can simplify:

We know that:

x + y = 9

then:

y = 9 - x

replacing that in the equation:

(x + 1) - 2*y

we would get:

x + 1 - 2*(9 - x)

x + 1  -18 + 2x

(x + 2x) + (1 - 18)

3x - 17

This means that we can write:

"the difference between one more than the larger number and twice the smaller number"

as: 3x - 17

Un batido de proteínas cuesta $ 5,25.

Step-by-step explanation:

El sistema de ecuaciones descrito al final del enunciado coincide con lo descrito al comienzo del mismo, de modo que podemos concentraron casi exclusivamente en la resolución del sistema en cuestión, la cual se describe a continuación:

Este es el sistema a resolver:

[tex]x + 4\cdot y = 25,50[/tex] (1)

[tex]3\cdot x + 2\cdot y = 24,00[/tex] (2)

Donde [tex]x[/tex] es el coste de un batido de fresa y [tex]y[/tex] corresponde al coste de un batido de proteínas:

1) Despejamos [tex]x[/tex] en (1):

[tex]x = 25,50 - 4\cdot y[/tex]

2) Eliminamos [tex]x[/tex] en (2):

[tex]3\cdot (25,50 - 4\cdot y) + 2\cdot y = 24,00[/tex]

[tex]76,50 - 12\cdot y +2\cdot y = 24,00[/tex]

3) Simplificamos y despejamos [tex]y[/tex]:

[tex]10\cdot y = 52,50[/tex]

[tex]y = 5,25[/tex]

Un batido de proteínas cuesta $ 5,25.

Answer:

Let the two equal angles be x . Hence the third angle is 3x . But the sum of the interior angles of a triangle always adds up to 180∘ . ∴x=1805=36∘

Answer:

Angle 1 = 36°

Angle 2 = 36°

Angle 3 = 108°

Step-by-step explanation:

Sum of all angles in any triangle is 180°

angle 1 = angle 2 = X

angle 3 = 3×X

angle 1 + angle 2 + angle 3 = 180°

X + X + 3×X = 5×X = 180°

X = 180° / 5 = 36°

Angle 1 = 36°

Angle 2 = 36°

Angle 3 = 108°

Step-by-step explanation:

Given

Jennifer has $400 more than Brian

Suppose Brian has x amount initially

So, Jennifer has 400+x

If Jennifer gives 20% of her to Brian, then brian would have two-third of the amount Jennifer left with

[tex]\Rightarrow \dfrac{2}{3}\times [400+x](1-0.2)=[400+x](0.2)+x\\\\\Rightarrow \dfrac{2}{3}\times 0.8\times (400+x)=80+0.2x+x\\\\\Rightarrow 213.334+0.533x=80+1.2x\\\Rightarrow 133.334=0.66x\\\Rightarrow x=\$202.02[/tex]

Thus, Brain has [tex]\$202[/tex]

Step-by-step explanation:

Answer:

If you consider what the slope looks like for a vertical line, it is an infinite slope. What that means is that you cannot have a y-value in your equation:

x = 3

This x-value would be a vertical line that passes through all y-values for x = 3. So you can replace them in (3, y) with any value, and it will be included in the linear equation x = 3.

Answer:

17.708333% increase

Step-by-step explanation:

To find the percent increase take the new price and subtract the old price

5650-4800

850

Divide by the old price

850/4800

0.177083333

Change to percent form

Answer:

x = 1

Step-by-step explanation:

6x - 9 = 2x - 5

Move variables to one side

6x - 9 = 2x - 5

-2x       -2x

4x - 9 = - 5

Isolate variable

4x - 9 = - 5

    + 9    +9

4x = 4

4x/4 = 4/4

x = 1

Answer:

60+14.35=88.27

Step-by-step explanation:

5x12 for the rectangle on the right, then for the circle, using the formula A=πr², I get 28.27, which you divide by 2 because you only need half of the circle, and you get 88.27. I calculated the radius by subtracting 12-6 and then dividing that in half because the radius is half of the distance to the other end of the circle. Then you get the radius of 3, then plug it into the formula to get π(3)², which is just 3.14(9), and you get 28.27.

Answer:

P = 37.42478 A = 88.27

log(10) 2500 = log(10) (5^2*10^2) = log(10) 5^2 + log(10) 10^2 = 2*log(10) 5 + 2=3.398

Let the ages be 3x and 4x

ATQ

[tex]\\ \Large\sf\longmapsto 4x-3x=5[/tex]

[tex]\\ \Large\sf\longmapsto x=5[/tex]

Now

[tex]\\ \Large\sf\longmapsto Age\:of\:Minu=3x=3(5)=15years[/tex]

[tex]\\ \Large\sf\longmapsto Age\:of\:Sudhir=4x=4(5)=20years[/tex]

Their present ages are 15 and 20 years.

Let the age of Minu be represented by x

Since the difference between their ages is 5 years, then the age of her brother will be x + 5.

Based on the information given in the question, the equation to use in solving the question will be:

x/(x + 5) = 3/4

Cross multiply

(4 × x) = 3(x + 5)

4x = 3x + 15

Collect like terms

4x - 3x = 15

x = 15

Minu's age is 15 years

Therefore, her brother's age will be:

= x + 5

= 15 + 5

= 20 years

In conclusion, their present ages are 15 and 20 years.
