The slope of the line below is -2. Write the point-slope equation of the line
kipiarov [429]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y-y_{0}=m(x-x_{0})

Where:

m: It is the slope of the line

(x_ {0}, y_ {0}): It is a point through which the line passes.

We have to:

m = -2

Thus, the equation is of the form:

y-y_{0}=-2(x-x_{0})

We substitute the point (x_{0}, y_{0}) :( 4, -6)

y-(-6)=-2(x-4)\\y+6=-2(x-4)

Finally, the equation is:

y+6=-2(x-4)

Answer:

y = -2x + 2

y+6=-2(x-4)

Assume that Emily (who has CF, a recessive disease (aa)) decides to have children with a man who does not have CF and who has no
alukav5142 [94]

Answer:100%. Probability

Step-by-step explanation:

Emily = aa

Man = AA

After crossing the two, the result wI'll be Aa, Aa, Aa, Aa

Since every result has a carrier(a) in it, makes it 100% probability.

The motion of a ship riding at anchor can be modeled by y=25-4 cos (pi/6)t, where y is the water depth in feet and t is the time
balandron [24]

Answer: 29 feet (deepest) at 6 am

              21 feet (shallowest) at Midnight & Noon

<u>Step-by-step explanation:</u>

y = -4 cos (π/6)t +25

Amplitude (A) = 4    

-A means it is a reflection over the x-axis (starts at minimum)<em> </em>

Period = 2π/B   →  Period = 12

Phase shift = C/B   →  Phase Shift = 0

Midline (D) = 25

Midline (D) ± Amplitude (A) = Max & Min

Max: 25 + 4 = 29

Min: 25 - 4 = 21

Change the coordinates of y = cos (x) as follows:

  • x-value: Add C then divide by B
  • y-value: Multiply by A then add D

Note that the equation shows: A = -4, B = π/6, C = 0, D = 25

\begin{array}{c|ccc|cl}\underline{\quad x\quad}&\underline{\quad y\quad}&&\underline{\quad (x+C)/B\quad}&\underline{\quad Ay+D\quad}\\0&1&&0&21&minimum\\\pi&0&&3&25&midline\\\pi &-1&&6&29&maximum\\3\pi/2&0&&9&25&midline\\2\pi&1&&12&21&minimum\\\end{array}

Evaluate the expression if a = 2, b = −3, c = −4, h = 6, y = 4, and z = −1.
Dima020 [189]

The required values are 11 and 19

Given the expression;

15−||2−3a||

If a = 2

Substitute the given value into the expression

If the moduli expression is positive

15−(2−3a)

= 15 - (2-3(2))

= 15 - (2-6)

= 15 - (-4)

= 15 + 4

= 19

If the moduli expression is negative

= 15 - -(2-3(2))

= 15 - -(2-6)

= 15 - -(-4)

= 15 - +4

= 15 - 4

= 11

Hence the required values are 11 and 19
