Answer:

x = 125

Step-by-step explanation:

Tangents from an external point to a circle are congruent , that is

CA = CB

Then Δ ABC is isosceles with base angles being congruent

∠ BAC = ∠ ABC = $\frac{180-70}{2}$ = $\frac{110}{2}$ = 55°

∠ ABC and x are adjacent angles on a straight line and sum to 180° , so

x = 180° - 55° = 125°

Then x = 125

Select the correct answer.<br> Which function has the same graph as x + y = 11?

Zinaida [17]

The function that has the same graph as x + y = 11 is f(x) = -x + 11

<h3>Graph of functions</h3>

From the question, we are to determine the function that has the same graph as the given equation

The given equation is

x + y = 11

In the above equation, y is the dependent variable.

and

Among the given equation, f(x) is the dependent variable

Thus, we can write that

x + f(x) = 11

Isolate f(x)

f(x) = -x + 11

Hence, the function that has the same graph as x + y = 11 is f(x) = -x + 11

Pls help me with number

vredina [299]

Answer:

Total people = 240

Step-by-step explanation:

Let the total number of people by 'x'.

$\sf \text{Number of men =$ \dfrac{1}{4}*x$} \\$

$\sf \text{Number of women =$\dfrac{1}{3}x$}$

Number of children = 100

When we subtract the total number of men and women from the total people 'x', we get the number of children.

$\sf x - \left(\dfrac{1}{4}x+\dfrac{1}{3}x\right)= 100\\\\x - \left(\dfrac{1*3}{4*3}x+\dfrac{1*4}{3*4}x\right)=100\\\\$

$x- \dfrac{4+3}{12}x=100\\\\x - \dfrac{7}{12}x = 100\\\\ \dfrac{12}{12}x-\dfrac{7}{12}x = 100\\\\ \dfrac{5}{12}x=100\\$

$\sf x = 100*\dfrac{12}{5}\\$

x = 20 * 12

x = 240

<h3> Total number of people = 240</h3>
