To write a linear equation in standard form, move each variable term to the left side of the equation and simplify. Ax +By = C

Since x is on the right side of the equation, switch the sides so it is on the left side of the equation. 3/4 * (x+8) = y-4

Move all terms containing variables to the left side of the equation

3x/4 +6 = y-4

Move the y to the left side of the equation

3x/4+6-y=-4

Move all terms not containing a varbile to the right side

Move the 6 to the right side

3x/4-y=-6-4

Subtract 4 from -6

3x/4-y=-10

Find the LCD of A,B,C and you get 4

Then you * 4 by everything

3x/4*4-y*4=-10*4

Simplify each term

3x-4y=-10*4

Multiply -10 by 4

3x-4y=-40

Answer:

y = (3/4)x + 10

Step-by-step explanation:

y - 4 = 3/4 (x + 8)

y - 4 = (3/4)x + 6

y = (3/4)x + 10

An advertisement for a circular rug says that the rug has a diameter of 6 feet. Find the relative error of this measurement
Aleonysh [2.5K]

Answer:

1. 8.3%

Step-by-step explanation:

Relative error = absolute error/expected measurement

The expected measurement is given as 6 ft.

Now, the absolute error is usually equal to half of a unit of the measure.

This means the absolute error in this case is ½ × 1 = 0.5 ft

Thus, the exact measurement will be;

6 ± 0.5

Thus;

Relative error = 0.5/6

Relative error = 0.083

Expressing it in percentage gives 8.3%

A projectile is fired straight up from ground level with an initial velocity of 112 ft/s. Its height, h, above the ground after
PtichkaEL [24]

Answer:

Step-by-step explanation:

We can do this the easy way and just set up an inequality and let the factoring do the work for us. The inequality will look like this:

-16t^2+112t>192 We will move the constant over and get

-16t^2+112t-192>0 and when you factor this you get that

3 < t < 4

Between 3 and 4 seconds is where the projectile reaches a height higher than 192 feet. With a little more work and some calculus you can find the max height to be 196 feet.
