Tomas wrote the equation y = 3x +3/4. When Sandra wrote her equation, they discovered that her equation had all the same solutio

ns as Tomas’s equation. Which equation could be Sandra’s?
–6x + y = 3/2
6x + y = 3/2
–6x + 2y = 3/2
6x + 2y = 3/2

In order for Sandra's equation to have all the same solutions as Tomas's equation they need to lie on each other or in other words to be exactly the same.

So now we need to transform options in tomas equation form and compare.

First option:
y = 6x + 3/2    not the same

Second option:
y = -6x + 3/2   not the same

Third option:
-6x + 2y = 3/2   when -6x goes on other side it changes its sign and will become:
2y = 6x + 3/2
when we divide by 2 we get
y = 3x + 3/4 which marks with Tomas's equation

Answer is third option.

–6x + 2y = 3/2

or, 2y= 6x + 3/2
or, y= (6x + 3/2)/2
or, y = 6x/2 + 3/4
or, y = 3x + 3/4

Therefore, –6x + 2y = 3/2 is Sandra's equation.

What is the answer to 11x+4+51+2x+8=180
Digiron [165]
Hi,

Work:

Equation;

11x + 4 + 51 + 2x + 8 = 180

Collect like terms and calculate sum of positive numbers.

13x + 63 = 180

Move constant +63 to the right side and change its sign.

13x = 180 - 63

Subtract numbers.

13x = 117

Divide both sides of equation with 13.

x = 9


Hope this helps.

Answer:

Domain [-5,∞)

Range [0,∞)

Step-by-step explanation:

Part 1) Find the domain

we have

f(x)=\frac{1}{2}\sqrt{x+5}

we know that

The radicand must be greater than or equal to zero

so

x+5\geq 0

solve for x

subtract 5 both sides

x\geq -5

The solution for x is the interval [-5,∞)

All real numbers greater than or equal to -5

Remember that

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

therefore

The domain of the function f(x) is the interval  [-5,∞)

Part 2) Find the range

we have

f(x)=\frac{1}{2}\sqrt{x+5}

Find the value of f(x) for the minimum value of x

For x=-5

f(x)=\frac{1}{2}\sqrt{-5+5}

f(x)=0

The minimum value of f(x) is equal to zero

so

The solution for f(x) is the interval [0,∞)

All real numbers greater than or equal to 0

Remember that

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

therefore

The range of the function is the interval [0,∞)

A man bought a house for 3600 Naira he repairs the house with 150 Naira if he sold the house for 4950 Naira . Find his percentag
kozerog [31]

Step-by-step explanation:

profit%=

\frac{selling \: price - cost \: price}{cost \: price}  \times 100\%

\frac{4950 \: naira - 3600 \: naira + 150 \: naira}{3750 \: naira}  \times 100\%

\frac{4950 - 3750}{3750}  \times 100\%

\frac{1200}{3750}  \times 100\%

=36%
