Answer:

X = 11

Step-by-step explanation:

So, in order to solve this equation, we need to isolate x.

So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:

-2x + 7 = -15

Now in order to get x all alone on one side, we need to subtract 7 from the left side.

-2x = -22

Now we just have to divide the -2 from x.

X = 11

Answer:

x = 11

Step-by-step explanation:

6x + 7 = 8x - 15

Step 1: Subtract 8x from both sides.

6x+7−8x=8x−15−8x

−2x+7=−15

Step 2: Subtract 7 from both sides.

−2x+7−7=−15−7

−2x=−22

Step 3: Divide both sides by -2.

-2x/-2 = -22/-2

x = 11

A 12 foot ladder is leaning up against the side of a house the ladder makes an angle of 62° with the ground. How far up the side

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

The ladder forms a right angle triangle with the house and the ground. The length of the ladder represents the hypotenuse of the right angle triangle. The height, h from the top of the ladder to the base of the house represents the opposite side of the right angle triangle.

The distance from the bottom of the ladder to the base of the house represents the adjacent side of the right angle triangle.

To determine the height, h that the ladder reaches, we would apply

the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin 62 = h/12

h = 12Sin62

h = 12 × 0.8829

h = 10.6 feet

Answer:

8i+3j

Step-by-step explanation:

let point P2(0,3)

point P1(-8,0)

vector P1P2= Position vector of P2- position vector of P1

vector= (0,3)-(-8,0)

vector= (8,3)
