Inverse Function -5 + 5/2x

Mathematics
1 answer:
Lapatulllka [165]3 years ago
3 0

Answer:

y = (2/5)x + 2

Step-by-step explanation:

To find the inverse of a function, we simply exchange the variables x and y and solve for y.

For this function we will write it as such:

y = -5 + (5/2)x

So to find the inverse, we will swap the x and y and solve.

y = -5 + (5/2)x

x = -5 + (5/2)y

x + 5 = (5/2)y

(2/5) * (x + 5) = y

(2/5)x + (2/5)5 = y

(2/5)x + 2 = y

Thus the inverse of the function is:

y = (2/5)x + 2

Cheers.

I did the first one I need help on this that’s all

Answer:

m<A = 70 deg

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 deg. Add the three measures and set equal to 180. Solve for x. then use the value of x and the expression for m<A to find the measure of angle A.

m<A + m<B + m<C = 180

5x - 25 + 2x + 10 + 3x + 5 = 180

10x - 10 = 180

10x = 190

x = 19

m<A = 5x - 25 = 5(19) - 25 = 95 - 25 = 70

Answer: m<A = 70 deg

What is the simplified form of the quantity 1 over b minus 1 over a all over the quantity 1 over b plus 1 over a?
jolli1 [7]

Option B: (b-a)/(b+a) is the correct answer

Step-by-step explanation:

The given expression is;

\frac{\frac{1}{b}-\frac{1}{a}}{\frac{1}{b}+\frac{1}{a}}

First of all we have to take LCM in both numerator and denominator

So,

=\frac{\frac{b-a}{ab}}{\frac{b+a}{ab}}

The reciprocal of the denominator will be multiplied with the numerator for simplification

So,

=\frac{b-a}{ab} * \frac{ab}{b+a}\\= \frac{b-a}{b+a}

Hence,

Option B: (b-a)/(b+a) is the correct answer

The steps are :

\frac{1}{5} y -  \frac{3}{5} y + 5 -  \frac{2}{5} y - 8

= ( \frac{1 - 3 - 2}{5} y) + (5 - 8)

=  -  \frac{4}{5} y - 3
