Step-by-step explanation:

Step 1: Define

7x = 2(x - 50)

Step 2: Solve for x

Distribute 2: 7x = 2x - 100
Isolate x term: 5x = -100
Isolate x: x = -20

Answer:

x= -20

Step-by-step explanation:

So the first thing you would want to do is multiply 2 on both x and -50. After that you will end up with 7x = 2x - 100. Then you will need to subtract x on both sides getting 5x = -100. Finally you will need to divide 5 on both sides getting x = -20

Leave the answer as an improper fraction

Hey there!

ANSWER: $\frac{23}{20}$

EXPLANATION:

To find the answer to your question, you will need to add.

$\frac{3}{4}+\frac{2}{5}$

First, multiply the denominator.

$5*4=20$

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

$5*3=15$

Now multiply 4 bu 2.

$4*2=8$

If you want to get the numerator, add what you got after multiply.

$15+8=23$

The numerator is 23. So now let's complete the fraction.

$\frac{23}{20}$

This is your answer!

Hope this helps!

Pls help meh pls Find the area of the figure. (Sides meet at right angles.)

Vlad [161]

We find the area of the total square which is 8in • 8in=64in^2 . Now we find the area of the small quadrilateral which is 4in•4in=16 in^2.
Now we subtract the area of the small quadrilateral from the big quadrilateral’s area 64in^2 -16in^2 leaving us with the are of 48in^2 of the figure

Suppose the invertible function φ(x) has the domain (−5,11) and the range (−12,1).

Rom4ik [11]

Answer:

Range of $\phi^{-1}$ is (−5,11).

Step-by-step explanation:

Given the invertible function Ф(x) which has the domain (−5,11) and the range (−12,1).

Invertible function is the function that inverses another function i.e if y=Ф(x) then x=g(y) where g is called the inverse of Ф and denoted by $\phi^{-1}$

Given Ф(x) the function whose domain is (−5,11) and range is (−12,1). Therefore, by definition of invertible function there exist a function g with domain (−12,1) and range (−5,11) which is called the inverse function denoted by $\phi^{-1}$

Hence, Range of $\phi^{-1}$ is (−5,11)
