Answer:

The domain is x\geq 7

The range is y\geq 1

Step-by-step explanation:

we have

y=\sqrt{x-7} +1

<em>Find the domain</em>

Remember that

The domain of a function is the set of all possible values of x

we know that the radicand of the function must be greater than or equal to zero

so

x-7\geq 0

solve for x

x\geq 7

therefore

The domain is x\geq 7

<em>Find the range</em>

Remember that

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

For x=7

The value of y is equal to

y=\sqrt{7-7} +1=1

so

The solution for y is the interval [1,∞)

therefore

The range is y\geq 1

Line j has a slope of − 2. Line d is perpendicular to line j and passes through the point( − 8 , 3 ).  Write the equation for
Zina [86]

Answer:

The equation is: y = 1/2x + 7

Step-by-step explanation:

The slope of j is -2. The slope of a line perpendicular to line j has a negative inverse: 1/2. The point is (-8, 3).

Use the point slope form of the equation:

y - y1 = m(x - x1)

Substitute:

y - 3 = 1/2(x - (-8))

y - 3 = 1/2x + 4

y = 1/2x + 4 + 3

y = 1/2x + 7

Proof:

Solve for f(x) when x = -8.

f(x) = 1/2x + 7

f(-8) = 1/2(-8) + 7

= -8/2 + 7

= -4 + 7

= 3, giving the point (-8, 3)

C - 11 /9 = 9

Multiply both sides by 9

c - 11 = 81

add 11 to each side to isolate c

c = 81 + 11 = 92

Look at this equation: x2 - 29x - 132 = 0. What is the factored form of this equation?
Lady_Fox [76]
Use the commutative property to reorder the terms

2x-29x-132=0

Next step

Collect like terms

-27x-132=0

Move the constant to the right-hand side and change its sign

-27x=132

Divide both sides of the equation by

Solution or answer ———
X= - 44/9

Alternative form <———
X =-4 8/9 ,x=-4.8

Any of those are the answer
