Cada persona equivale a 71.50

Entonces:

\sf \rightarrow929.50 \div 71.50 = 13929.50

\: { \sf \rightarrow13929.50÷71.50=13}

Naily [24]

Answer:

To find f-¹(x) of f(x) equate f(x) to y

That's

f(x) = y

So we have

y =  \frac{4x - 7}{10}

Next interchange the variables that's x becomes y and y becomes x

That's

x =  \frac{4y - 7}{10}

Next make y the subject

Cross multiply

We have

4y - 7 = 10x

Move -7 to the right side of the equation

4y = 10x + 7

Divide both sides by 4

We have the final answer as

y =  \frac{10x + 7}{4}

So

f ^{ - 1} (x) =  \frac{10x + 7}{4}

Hope this helps you

What is the measure of angle of 1?
Ludmilka [50]

Answer:

m<1 = 118

Step-by-step explanation:

The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that

(28) + (90) = m<1

Remember, a box around an angle signifies that its measure is (90) degrees.

Solve this problem by performing the operation,

118 = m<1

15 Points!! Is this my teacher's fault? The math and the picture aren't making sense. The blue is my answer.
kogti [31]

Answer:

Your teacher is correct.

Step-by-step explanation:

So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.

With this information in mind, we can create the expression:

2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)

Now simply the equation:

6x + 48 = 180

6x = 132

6x/6 = 132/6

x = 22

Angle C = 44

Angle B = 88
