How to get y by itself in the equation x+2y=10

Mathematics
1 answer:
Nataly_w [17]3 years ago
4 0

Answer:

The value of y by itself in the equation x+2y=10 is

y=\frac{10-x}{2}

Step-by-step explanation:

Given equation is x+2y=10  -------- (1)

To find y with given equation as below :

Equation (1) implies that x+2y=10

Subtracting the above equation by x we get

x+2y-x=10-x

x-x+2y=10-x

2y=10-x

Dividing by 2 on both sides we get

\frac{2y}{2}=\frac{10-x}{2}

y=\frac{10-x}{2}

Therefore the value of y is \frac{10-x}{2}

Therefore the value of y by itself in the equation x+2y=10 is

y=\frac{10-x}{2}

The angle measures associated with which set of ordered pairs share the same reference angle? (Negative StartFraction StartRoot
Katarina [22]

Answer:

(C)\left(-\dfrac{1 }{2},-\dfrac{\sqrt{3} }{2} \right)$ and \left(\dfrac{1 }{2},\dfrac{\sqrt{3} }{2} \right)

Step-by-step explanation:

The reference angle is the angle that the given angle makes with the x-axis.

For an ordered pair to share the same reference angle, the x and y coordinates must be the same or a factor of each other.

From the given options:

(A)\left(-\dfrac{\sqrt{3} }{2} ,-\dfrac{1 }{2}\right)$ and \left(-\dfrac{1 }{2},-\dfrac{\sqrt{3} }{2} \right)\\\\(B)\left(\dfrac{1 }{2},-\dfrac{\sqrt{3} }{2} \right)$ and \left(-\dfrac{\sqrt{3} }{2}, \dfrac{1 }{2}\right)\\\\(C)\left(-\dfrac{1 }{2},-\dfrac{\sqrt{3} }{2} \right)$ and \left(\dfrac{1 }{2},\dfrac{\sqrt{3} }{2} \right)\\\\(D)\left(\dfrac{\sqrt{3} }{2},\dfrac{1 }{2} \right)$ and \left(\dfrac{1 }{2},\dfrac{\sqrt{3} }{2} \right)

We observe that only the pair in option C has the same x and y coordinate with the second set of points being a negative factor of the first term. Therefore, they have the same reference angle.

Describing Function Notation of a Scenario
san4es73 [151]

Answer:

v(h) represents the volume of the water (ft³) in the pool at h hours

h is the number of hours

When h increased v(h) decreased

Step-by-step explanation:

- A swimming pool has about 603 cubic feet of water

∴ The volume of the water in the pool initially is 603 feet³

- The pool liner has a small hole and is leaking at a rate of 15  cubic

   feet each hour

∴ The rate of decreasing of the volume of the water in the pool is

   15 feet³ per hour

- The volume of the the water v at a time h hour can represented by

  a linear function v(h)

∴ v(h) = -15 h + 603 , where v(h) is the volume of the water in the

   pool in cubic feet at h hour

- Let us put an example to understand the relation between v(h)

  and h

- Assume that h = 0

∵ h = 0

∴ v(0) = -15(0) + 603

∴ v(0) = 603 ft³ ⇒ The volume of the water at the beginning

- Assume that h = 2 hours, that means we need to know the volume

  of the water after two hours

∵ h = 2 hours

∴ v(2) = -15(2) + 603

∴ v(2) = -30 + 603 = 573 ft³

∵ h increased from 0 to 2

∴ v(t) decreased from 603 ft³ to 573 ft³

∴ The volume decreased when the number of hours increased

* v(h) represents the volume of the water (ft³) in the pool at h hours

* h is the number of hours

* When h increased v(h) decreased
