Answer:

The Domain is x>-7 or C

The Range is x>5 or b

Step-by-step explanation:

edge

The domain of the function y = √(x+7) + 5 is [-7, ∞).

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The given equation is y = √(x+7) + 5.

For the expression under the square root to be non-negative, we must have x + 7 ≥ 0.

The domain of the function is all real numbers greater than or equal to -7.

Thus,

The domain of the function y = √(x+7) + 5 is [-7, ∞).

Answer:

75 degrees

Step-by-step explanation:

3x+15 = 4x - 5

-3x       -3x

15=x-5

+5    +5

x=20

4(20)-5 = 75

Answer:

75

Step-by-step explanation:

1 and 2 are corresponding angles meaning that they are equal to each other or congruent

so we set up an equation

4x-5=3x+15 and since for x

step 1 subtract each side by 3x

4x-3x=x

now we have

x-5=15

step 2 add 5 to each side

5+15=20

x=20

now we just plug in 20 to 4x - 5

4x20=80

80-5=75

therefore your answer is 75

Answer: t= 3/2

Step-by-step explanation: 5/ 7 1/2 = 3/2

Answer:

t = 7/10 = 0.700

Step-by-step explanation:

STEP

1

:

           1

Simplify   —

           2

Equation at the end of step

:

            1

 5t -  (7 • —)  = 0

            2

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

          5t     5t • 2

    5t =  ——  =  ——————

          1        2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

5t • 2 - (7)     10t - 7

————————————  =  ———————

     2              2  

Equation at the end of step

2

:

 10t - 7

 ———————  = 0

    2  

STEP

3

:

When a fraction equals zero :

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 10t-7

 ————— • 2 = 0 • 2

   2  

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  10t-7  = 0

Solving a Single Variable Equation:

3.2      Solve  :    10t-7 = 0

Add  7  to both sides of the equation :

                     10t = 7

Divide both sides of the equation by 10:

                    t = 7/10 = 0.700

One solution was found :

t = 7/10 = 0.700
