Y=x+5 and y= (3)/(2)x - 5

zheka24 [161]

Step-by-step explanation:

Given:

Two Equations

y = x + 5 ..................(1)

y = (3/2) x - 5 ...................(2)

Both are considered as Equation (1) and (2) respectively,

Equating the equation 1 and 2, we get

⇒ x + 5 = (3/2) x - 5

⇒ x - (3/2) x = - 5 - 5

⇒ (2x - 3x) /2 = - 10

⇒ - x = - 20

⇒ x = 20

Now substituting "x = 20" in equation (1), we get

⇒ y = 20 + 5

⇒ y = 25

Thus, we get the value of x = 20 and value of y = 25.

3. Evaluate at the given value: g(x)=-2x+7, g^-1(-2)

Juli2301 [7.4K]

Answer:

<h2> ${g}^{ - 1} ( - 2) = \frac{9}{2}$ </h2>

Step-by-step explanation:

To find g-¹( 2) we must first find g-¹(x)

To find g-¹(x) equate g(x) to y

That's

y = g(x)

We have

y = - 2x + 7

Now interchange the terms that's x becomes y and y becomes x

We have

x = - 2y + 7

Make y the subject in order to find g-¹(x)

Move 7 to the left side of the equation

- 2y = x - 7

Multiply both sides by - 1

We have

2y = 7 - x

Divide both sides by 2 to make y stand alone

That's

<h3> $y = \frac{7 - x}{2}$ </h3>

So we have

<h3> $g ^{ - 1} (x) = \frac{7 - x}{2}$ </h3>

Now to find g-¹(- 2) substitute the value of x that's - 2 into the expression

We have

<h3> ${g}^{ - 1} ( - 2) = \frac{7 - - 2}{2} \\ {g}^{ - 1} ( - 2) = \frac{7 + 2}{2}$ </h3>

We have the final answer as

<h3> ${g}^{ - 1} ( - 2) = \frac{9}{2}$ </h3>

Hope this helps you

33 folders cost $ 2.91 $2.91dollar sign, 2, point, 91. Which equation would help determine the cost of 2 22 folders? Choose 1 an

Rama09 [41]

Answer:

Option B. start fraction, 2, divided by, x, end fraction, equals, start fraction, 3, divided by, dollar sign, 2, point, 91, end fraction

Step-by-step explanation:

<u><em>The correct question is</em></u>

3 folders cost $2.91 which equation would help determine the cost of 2 folders

we know that

3 folders cost $2.91

so

by proportion

Determine the cost of 2 folders

Let

x ----> the cost of 2 folders

$\frac{2}{x}=\frac{3}{2.91}$

solve for x

$3x=2(2.91)$

$x=\$1.94$

therefore

The cost of 2 folders is $1.94
