Does that work?

Triangle angle - sum theorem<br> what is the value of y?

dangina [55]

Answer:

y = 5

Step-by-step explanation:

All angle measures in a triangle add up to 180°.

This means that 63 + 82 + 7y = 180

<u>Solving for Y:</u>

Step 1: Combine like terms.

$(7y) + (63+82)=180$
$7y + 145 = 180$

Step 2: Subtract 145 from both sides.

$7y + 145 - 145 = 180 - 145$
$7y = 35$

Step 3: Divide both sides by 7.

$\frac{7y}{7} = \frac{35}{7}$
$y = 5$

Step 4: Check if solution is correct.

$7(5) + 63 + 82 = 180$
$35 + 63 + 82 = 180$
$98 + 82 = 180$
$180 = 180$

Therefore, y = 5.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Write a function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11|.

Jet001 [13]

The function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11| is; g(x) = x + 8

<h3>How to solve transformation problems?</h3>

Transformations are used to change the position of a function from one point to another.

Now, we are given the function as;

f(x) = -3 + |x - 11|

To reflect the function above across the y-axis, we will make use of the following transformation rule: (x, y) → (-x, y)

Thus, since we are given f(x) = -3 + |x - 11|, applying the transformation rule above gives us;

f(-x) = -3 + |-1(x - 11)|

Removing the absolute sign gives us;

f(-x) = -3 + x + 11

f(-x) = x + 8

Thus, the function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11| is; g(x) = x + 8

A family of 3 children and 2 adults visited a health club. The club charges $y an hour for each child and $x an hour for each ad

vovikov84 [41]

Solution:

A family of 3 children and 2 adults visited a health club. The club charges $y an hour for each child and $x an hour for each adult.

First we make inequality according to question.

In a family number of children 3

Charge for 1 child = $y per hour

Charge for 3 children = 3y

Charge for 1 Adult = $x per hour

Charge for 2 adults = 2x

If the family does not want to s[end more than $30 an hour at health club.

$\therefore 2x+3y\leq 30$

Where, x and y should be greater than 0.

$\therefore x\geq 0,y\geq 0$

Now we make the graph of this inequality.

First we take equality of equation and then find x and y table.

2x+3y=30

x y

0 10

Here we have inequality. So, we have to take a test point (0,0)

$2(0)+3(0)\leq 30\Rightarrow 0\leq 30$

This statement is true. So, Graph will shade towards the test point (0,0)

Please see the attachment for graph.
