PLEASE! IM STUCKKKKK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ana va a cumplir los 36 anos de edad.

Answer:

Step-by-step explanation:

g(2) = 3(2) + 1 = 6 + 1 = 7

h(7) = 2(7) - 1 = 14 - 1 = 13

Using composite functions, it is found that:

[tex](h \circ g)(2) = 13[/tex]

The composition of functions h(x) and g(x) is given by:

[tex](h \circ g)(x) = h(g(x))[/tex]

In this problem, the functions are:

[tex]h(x) = 2x - 1[/tex]

[tex]g(x) = 3x + 1[/tex]

Then:

[tex]h(g(x)) = h(3x + 1) = 2(3x + 1) - 1 = 6x + 2 - 1 = 6x + 1[/tex]

At x = 2:

[tex](h \circ g)(2) = 6(2) + 1 = 13[/tex]

Answer:

1-x/7

Write x/7 as a fraction.

Answer:

  x = 5

Step-by-step explanation:

Add 13-8x to both sides of the equation, then divide by the coefficient of x.

  2 +8x +13 -8x = 11x -13 +13 -8x

  15 = 3x . . . . simplified

  5 = x

Answer:

x=5

2+8x=11x-13

8x-11=-13-2

-3x=-15

x=5

Hey! I've had the same quiz earlier and these answers below are correct. Hope this helps you out and have a great day :)

We have proved that m∠ABC is an obtuse angle.

m∠ABC = m∠ABD + m∠DBC

100° = 60° + 40°

Given,

m∠ABD = 60°

m∠DBC = 40°

We need to prove that m∠ABC is an obtuse angle.

The angles greater than 90 degrees but less than 180 degrees are called obtuse angles.

We have,

From the figure.

m∠ABD = 60°

m∠DBC = 40°

We see that

m∠ABC = m∠ABD + m∠DBC

m∠ABC = 60° + 40°

m∠ABC = 100°

m∠ABC is greater than 90 degrees and less than 180 degrees so,

m∠ABC is an obtuse angle.

Thus we have proved that m∠ABC is an obtuse angle.

Step-by-step explanation:

JL comprises of JK & KL. So ,

JL = JK + KL

Here the length of :-

KL= 9x + 3

JL = 55

JK = 7x + 4

So putting all the values above gives ,

7x + 4 + 9x + 3 = 55

=> 16x + 7 = 55

=> 16x = 55 - 7

= 48

=> x = 48/16 = 3

Using the value of x in finding the length of KL ,

KL = 9 × 3 + 3 = 27 + 3 = 30

Step-by-step explanation: If you subtract 23 from 23/ 23-23=0 and 23-(-23)= 0. Hope this helps!

James can do 23 to turn it into 0 by adding a negative number 23 or subtracting a number 23. Then the correct options are B and C.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

A class is playing a game where they add or subtract numbers to come up with another target number.

Answer: 16 months or 1 and half year.

Step-by-step explanation:

given data:

46 percent of this energy is used for heating and cooling.

15 percent for heating water.

15 percent for refrigerating and freezing.

and the remaining 24 percent for lighting, cooking, and running other appliances.

Solution:

if the family spent $1200 on yearl bill, the cost of energy used in heating and cooling

= 46/100 * $1200

= $552 yearly.

by adding insulation the cost of heating and can be redu up to 30percent.

= 30/100 * $552

= $165.6.

if $220 determin how long it would take for the insulation to pay for it self from the energy it saves.

$165.6 would be saved yearly, this makes it an average of $13.8 saved monthly.

to determine the time it would take to settle the cost of insulation from energy saved

= $220/13.8

= 15.9 months

which Is approximately 16 months or 1 and half year to pay for the insulation.

Answer:

r = 0.9

Step-by-step explanation:

Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.

We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;

r² = 81%

Or r² = 0.81

Thus, the numerical value of the correlation r would be;

r = √0.81

r = 0.9

Answer:

-2 (6x - y) = -12x + 2y

Step-by-step explanation:

By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y
