Write the equation of a line that is perpendicular to the given line and that passes through the given point.
HACTEHA [7]
First, let's re-arrange to slope-intercept form.

x + 8y = 27

Subtract 'x' to both sides:

8y = -x + 27

Divide 8 to both sides:

y = -1/8x + 3.375

So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.

So the slope of the perpendicular line will be 8.

Now we can plug this into point-slope form along with the point given.

y - y1 = m(x - x1)

y - 5 = 8(x + 5)

y - 5 = 8x + 40

y = 8x + 45

Use the quadratic formula to solve the equation to the exact value or round to two decimal places.
lys-0071 [83]
First set everything to 0.
{x}^{2}  + x - 5
Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.

Answer:

r=5.4

As mentioned above, the actual \goldE{\text{total quantity}}total quantitystart color #a75a05, start text, t, o, t, a, l, space, q, u, a, n, t, i, t, y, end text, end color #a75a05 is 1000-10=\goldE{990}1000−10=9901000, minus, 10, equals, start color #a75a05, 990, end color #a75a05 grams, since we are trying to find the volume of the air within the shell.

Let's denote the ball's radius as rrr. Then, the \maroonD{\text{volume}}volumestart color #ca337c, start text, v, o, l, u, m, e, end text, end color #ca337c is \maroonD{\dfrac43\pi r^3}

Gale's Shipping Company charges $3.00 plus an additional $5.00 per pound to ship a package. Peeta's Shipping Company charges $12
AURORKA [14]

Answer:

Gale's Shipping Company Cost, y=$(3+5x)

Peeta's Shipping Cost, y=$(12+2x)

Step-by-step explanation:

Let the number of pounds being shipped=x

Gale's Shipping Company charges $3.00 plus an additional $5.00 per pound to ship a package.

Gale's Shipping Company Cost =  $3.00 + ($5.00 X Number of Pounds)

Gale's Shipping Company Cost, y=$(3+5x)

Peeta's Shipping Company charges $12.00 plus an additional $2.00 per pound to ship a package.

Peeta's Shipping Cost =  $12.00 + ($2.00 X Number of Pounds)

Peeta's Shipping Cost, y=$(12+2x)
