Answer:

x = 21

Step-by-step explanation:

[tex](5 y + 10) \degree = y \degree + 90 \degree \\ (vertical \: \angle s) \\ \\ (5 y + 10 - y) \degree = 90 \degree \\ \\ (4 y + 10 ) \degree = 90 \degree \\ \\ 4y + 10 = 90 \\ \\ 4y = 90 - 10 \\ \\ 4y = 80 \\ \\ y = \frac{80}{4} \\ \\ y = 20 \\ \\ (5 y + 10) \degree = (5 \times 20 + 10) \degree = 110 \degree \\ \\ (5 y + 10) \degree + (3x + 7) \degree = 180 \degree \\ (linear \: pair \: \angle s) \\ \\ 110 \degree + (3x + 7) \degree = 180 \degree \\ \\ (3x + 7) \degree = 180 \degree - 110 \degree\\ \\ (3x + 7) \degree = 70 \degree \\ \\ 3x + 7 = 70 \\ \\ 3x = 70 - 7 \\ \\ 3x = 63 \\ \\ x = \frac{63}{3} \\ \\ x = 21[/tex]

The value of x and y are 21 and 20 degrees respectively.

Linear pairs of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.

WE are given two adjacent angle (5y + 10) and (3x + 7)º

These angles make a linear pair so,

(5y + 10) + (3x + 7)º = 180

Also, we can see that angle Y and  (3x + 7)º lies on a straight line then;

y +  (3x + 7)º + 90 = 180

(3x + 7)º = 180 - 90 - y

(3x + 7)º = 90 -y

Now replace  (3x + 7)º by 90 - y in the first equation.

(5y + 10) + (3x + 7)º = 180

(5y + 10) + (90 - y )º = 180

Finally, simplify;

4y + 100 = 180

4y = 80

y = 20

Now, (3x + 7)º = 90 -y =90 - 20

(3x + 7)º =  70

3x = 70 - 7

3x = 63

x = 21

Hence, the value of x and y are 21 and 20 degrees respectively.

Answer:

a)

[tex]\displaystyle x=-\frac{1}{2}p\pm\sqrt{\frac{1}{4}p^2-4}[/tex]

b) p is in the interval (-4,4)

Step-by-step explanation:

Quadratic Equation

It's given the following quadratic equation:

[tex]x^2+px+4=0[/tex]

a)

It's required to complete squares and find the roots. This can be done by recalling the polynomial identity:

[tex]a^2+2ab+b^2=(a+b)^2[/tex]

We already have the first term squared, and we need to find the second term. Rewriting the equation:

[tex]\displaystyle x^2+2(\frac{1}{2}px)+4=0[/tex]

The second term of the binomial is 1/2p, thus completing the squares with [tex]b^2[/tex]:

[tex]\displaystyle x^2+2(\frac{1}{2}px)+\left(\frac{1}{2}p\right)^2+4-\left(\frac{1}{2}p\right)^2=0[/tex]

Factoring:

[tex]\displaystyle \left(x+\frac{1}{2}p\right)^2+4-\frac{1}{4}p^2=0[/tex]

Moving the independent term to the right side:

[tex]\displaystyle \left(x+\frac{1}{2}p\right)^2=\frac{1}{4}p^2-4[/tex]

Taking the square root:

[tex]\displaystyle x+\frac{1}{2}p=\pm\sqrt{\frac{1}{4}p^2-4}[/tex]

Solving for x:

[tex]\displaystyle x=-\frac{1}{2}p\pm\sqrt{\frac{1}{4}p^2-4}[/tex]

b) If the equation won't have real roots, then the radicand should be negative:

[tex]\displaystyle \frac{1}{4}p^2-4<0[/tex]

Factoring:

[tex]\displaystyle \left(\frac{1}{2}p-2\right)\left(\frac{1}{2}p+2\right)<0[/tex]

The zeros of the left-side polynomial are:

[tex]\displaystyle \frac{1}{2}p-2=0[/tex]

[tex]\displaystyle \frac{1}{2}p=2[/tex]

p = 4

[tex]\displaystyle \frac{1}{2}p+2=0[/tex]

[tex]\displaystyle \frac{1}{2}p=-2[/tex]

p = -4

The inequality:

[tex]\displaystyle \left(\frac{1}{2}p-2\right)\left(\frac{1}{2}p+2\right)<0[/tex]

Is satisfied for values of p in the interval (-4,4)

Answer:

The value of x is 6

Step-by-step explanation:

The formula of the area of the rectangle is A = l × w, where

In the rectangle ABCD

∵ AB = 2x cm

∴ l = 2x

∵ AD = x cm

∴ w = x

→ Use the formula of the area above to find its area

∵ A = 2x × x

∴ A = 2x²

∵ The area of the shaded region = 50 cm²

→ When the shaded region removed, then the remaining area is the

   unshaded region

∵ The area of unshaded region = 22 cm²

∵ The area the ABCD = area the shaded region + area unshaded region

∴ A = 50 + 22

∴ A = 72 cm²

→ Equate the two right side of A

∵ 2x² = 72

→ Divide both sides by 2

∴ x² = 36

→ Take √  for both sides

∴ x = 6

∴ The value of x is 6

Answer:

you start counting from left to right

when you want to calculate the difference you have to choose two numbers that are next to each other and subtract second one from first one and because the different between every 2 numbers in order are the same numbers we call it a common difference.

Step-by-step explanation:

for example for 4 :

1. we can choose two numbers next to each other like 1 and 1.1

2. subtract second from first like 1.1 - 1 = 0.1

3. 1.1 + 0.1 = 1.2

1.2 + 0.1 = 1.3

and ...

so the common difference is 0.1

Answer:

La señora María debe pagar 463.635 guaraníes por concepto de intereses,

Step-by-step explanation:

Se recomienda utilizar el modelo de interés compuesto puesto que la tasa de interés es constante y periódico, dado que se conoce el monto a pedir prestado, la tasa de interés y el número de anualidades, se obtiene el monto final. La cantidad de dinero a pagar es la diferencia entre ese resultado y el monto a ser prestado.

El modelo de interés compuesto es representado por la siguiente fórmula:

[tex]C(t) =C_{o}\cdot (1+r)^{t}[/tex] (1)

Donde:

[tex]C_{o}[/tex] - Cantidad de dinero a prestar, medida en guaraníes.

[tex]r[/tex] - Razón de interés interanual, adimensional.

[tex]t[/tex] - Anualidad, medida en años.

[tex]C(t)[/tex] - Cantidad de dinero asociada a la anualidad actual, medida en guaraníes.

Si sabemos que [tex]C_{o} = 5.000.000[/tex], [tex]r = 0.03[/tex] y [tex]t = 3[/tex], entonces la cantidad de dinero asociada al término del período de préstamo es:

[tex]C(3) = 5.000.000\cdot (1+0.03)^{3}[/tex]

[tex]C(3) = 5.463.635[/tex]

Finalmente, la cantidad de dinero a pagar por concepto de intereses es:

[tex]\Delta C = 5.463.635-5.000.000[/tex]

[tex]\Delta C = 463.635[/tex]

y=4x+5(the first one)

y=4x+1

y=4x-4

Step-by-step explanation:

If the slope is the same, it is parallel

The equation for a linear equation is y=mx+b

mx is the slope

your original equation is y=4x-2, so the slope is 4.

To find which ones are parallel, you find the ones with the slope 4x(make sure it isn't -4x).

Answer:

250ml understand the concept please

The jug can hold 250 ml more liquid.

Let the jug can hold x ml liquid.

Given Rita filled 2/5 of a jug with fruit juice.

So, the amount of fruit juice is = 2/5 of x = 2x/5.

Then she added 200 ml milk.

Given the ratio of the fruit juice to milk is 3:2.

So,

[tex]\frac{2x}{5}:200=3:2\\\frac{\frac{2x}{5} }{200}=\frac{3}{2}\\2( \frac{2x}{5})=600\\\frac{4x}{5}=600\\ x=\frac{600*5}{4}\\x=750[/tex]

So the amount of fruit juice = [tex]\frac{2}{5}*750=300[/tex] ml.

Total amount of fruit juice and milk = 300+200=500 ml.

So the jug will hold = 750 - 500 =250 ml more.
