si sna es 12 años menor que eva y dentro de 7 años la edad de eva es el doble que la edad de ana que edad tiene eva​

Answers

Answer 1

Responder:

17

Explicación paso a paso:

Dejar ;

Edad de Eva = x

Edad de Ana = x - 12

Dentro de los 7 años de la edad de Eva, la edad de Ana será el doble

x + 7 = 2 (x - 12 + 7)

x + 7 = 2 (x - 5)

x + 7 = 2x - 10

x - 2x = - 10 - 7

-x = - 17

x = 17

Por lo tanto, Eva tiene 17 años.

Answer:

-0.391 < x < 0.391

Step-by-step explanation:

The Maclaurin series for cosine is:

cos(x) = ∑ (-1)ⁿ x²ⁿ / (2n)!

So the next term would be -x⁶/6!.  When the absolute value of this is less than the error:

│-x⁶/6!│< 0.000005

x⁶ / 720 < 0.000005

x⁶ < 0.0036

-0.391 < x < 0.391

Two less than three-fourths of a number is, at most, negative seventeen. what is the range of values for the number?

Answers

Answer:

[tex]x\leq -20[/tex]

values ranging from minus infinity to negative 20

Step-by-step explanation:

we write the inequality associated with the text in terms of the unknown number "x" as:

[tex]\frac{3}{4} x-2\leq -17[/tex]

then, we solve for "x" by adding 2 to both sides, and then isolating "x" on the left as shown below:

[tex]\frac{3}{4} x-2\leq -17\\\frac{3}{4} x\leq -17+2\\\frac{3}{4} x\leq -15\\3\,x\leq -60\\x\leq -\frac{60}{3} \\x\leq -20[/tex]

then, the range of x-values is from minus infinity to negative 20

What is Point-Slope Form? What is Slope Intercept Form? What is the Slope Formula?

Answers

Answer:

For the first part

1.) Negative

2.)zero

3.) undefined

4.) positive

The point slope formula is y-y1=m(x-x1). It is best to use if you already know the slope and one other point on the line. It is used to find another point on the line.

The slope-intercept form is used to show a line. To use this form, you need to know the slope and the y-intercept.

The slope formula is y=mx+b. M is the slope while b is the y-intercept.



The original price of a jacket for sale at a department store is $80. The store is having a 20%-off sale, and you have
a coupon that gives you an additional discount of 10% off the lowest sale price. How would you calculate the final
selling price of the jacket?

O Multiply the $80 original price by 0.2 and subtract the result from $80. Then multiply the new price by 0.1 and
subtract the result from the discounted price.

O Multiply the $80 price by 0.3.

O Multiply the $80 price by 0.8, and then multiply the $80 price by 0.9.

O Divide the $80 price by 0.8, and then divide the $80 price by 0.9



i think it’s the first one

Answers

You're right; the answer is the first choice.

Answer:

first option ,  $57.6

Step-by-step explanation:

$80 x 0.20 = $16

$80 - $16 = $64

$64 x 0.10 = $6.4

$64 - $6.4 = $57.6

above solution is the exact steps on the first option.

therefore the final price of the jacket is $57.6

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

As she has 60 seeds, firstly she must number each plant in order or randomly see the height, After that he can peek at random 10 plants to test the fertilizer.

Thus, the required answer is she needs to number each plant from 1 to 60 and randomly peek at 10 of them. Option c is correct.

Find the integers m and n such that (m+n√2)(1-√2)²=-2+2√2​

Answers

Answer:

m = n = 2

Step-by-step explanation:

(m + n√2)(1 - √2)² = -2 + 2√2

(m + n√2)(1 - 2√2 + 2) = -2 + 2√2

(m + n√2)(3 - 2√2) = -2 + 2√2

3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2

(3n - 2m)√2 + 3m - 4n = 2√2 - 2

3n - 2m = 2

4n - 3m = 2

3n - 2m = 4n - 3m

n = m

4n - 3n = 2

n = 2

m = 2

how do i solve this question 2x-14=4(p+5) ? all ik it that i have to distribute first.

Answers

Answer:

x=(4p+34)/2

p=(2x-34)/4

Step-by-step explanation:

2x-14=4(p+5)

2x-14=4p+20

2x=4p+34

If you are solving for x, it would be:

2x/2=4p+34/2

x=(4p+34)/2

If you are olving for p, it would be:

2x-34=4p

Divide 4 from both sides:

(2x-34)/4=p or p=(2x-34)/4

Answers

Answer:

The answer is "[tex]\bold{g(x) = -\frac{1}{2x} \ and \ g(x)= -3x-12}[/tex]".

Step-by-step explanation:

Please find the complete question in the attached file.

[tex]\to f(x) = 4x[/tex]

Following the y-axis reflexion, f(x) is 4(-x) = -4x after a [tex]\frac{1}{8}[/tex] vertical compression factor, f(x) is [tex]\frac{1}{8} \times -4x = \frac{1}{-2x}[/tex]

 The y axis reflecting indicates that its entire function is multiplied by -1  

so, [tex]f(x)=3x+12^{-1}[/tex]
