How do you solve this? x - 2y = 4
valentina_108 [34]
If you want to solve for x, then
add 2y to both sides
x=2y+4
if want to solve for y
minus x both sides and divide by -2
x-2y=4
-2y=-x+4
y=1/2x-2

Which is equivalent to..... algebra II engenuity
katrin2010 [14]

Answer:

The correct answer is second option  option

9¹/⁸ ˣ

Step-by-step explanation:

<u>Points to remember</u>

<u>Identities</u>

ᵃ√x = = x¹/ᵃ

√x = x¹/²

(xᵃ)ᵇ = xᵃᵇ

<u>To find the correct option</u>

It s given that,

(⁴√9)¹/² ˣ

By using the above identities we can write,

(⁴√9)¹/²ˣ = (9¹/⁴)¹/²ˣ     [ since ⁴√9 = 9¹/⁴]

 = 9⁽¹/⁴ * ¹/²⁾ ˣ

 = 9¹/⁸ ˣ

Therefore the correct answer is second option  option

9¹/⁸ ˣ

Write an equation for the graph shown in the form $y=ax b.$
Vedmedyk [2.9K]

The required straight equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

What are equations in a straight line?

A straight line's equation is given by y=mx+c, where c is the height at which the line intersects the y-axis (often referred to as the y-intercept) and m is the gradient.

According to the given graph,

We can see two points are (-5, 0) and (5, 2)

The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Here

x₁ = -5, y₁ = 0

x₂ = 5, y₂ = 2

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]

Substitute values in the equation, we get

⇒ y - 0 = (2 - 0)/(8-4)(x-(-5))

⇒ y - 30 = (2)/(-4)(x + 5)

⇒ y - 30 = -1/2(x + 5)

⇒ y = (-1/2)x - 5/2 + 30

⇒ y = -0.5x + 27.5

Thus, the required equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).
