Which expression below is equivalent to -3x+5(x+2)
kari74 [83]

Answer:


                                         Step-by-step explanation:

1.) Apply the distributive law

                5x + 5 * 2

2.) Multiply the numbers

       5 * 2 = 10 is equivalent to 5x + 10

3.) Group like terms

                 5x - 3 + 10

4.) Add/subtract the numbers

                  -3 + 10 = 7 is equivalent to 5x + 7

At what point on the parabola y = 3x^2 + 2x is the tangent line parallel to the line<br> y = 10x −2?
oksian1 [2.3K]

Answer:

( \frac{4}{3} , 8 )

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 10x - 2 ← is in slope- intercept form

with slope m = 10

Parallel lines have equal slopes

then the tangent to the parabola with a slope of 10 is required.

the slope of the tangent at any point on the parabola is \frac{dy}{dx}

differentiate each term using the power rule

\frac{d}{dx} (ax^{n} ) = nax^{n-1} , then

\frac{dy}{dx} = 6x + 2

equating this to 10 gives

6x + 2 = 10 ( subtract 2 from both sides )

6x = 8 ( divide both sides by 6 )

x = \frac{8}{6} = \frac{4}{3}

substitute this value into the equation of the parabola for corresponding y- coordinate.

y = 3(\frac{4}{3} )² + 2

   = (3 × \frac{16}{9} ) + 2

   = \frac{16}{3} + \frac{8}{3}

   = \frac{24}{3}

   = 8

the point on the parabola with tangent parallel to y = 10x - 2 is ( \frac{4}{3} , 8 )

What is the other endpoint if one endpoint is (10,12) and the midpoint is (6,9).?
Lubov Fominskaja [6]

Answer:

(2,\, 6).

Step-by-step explanation:

Let (x_{0},\, y_{0}) and (x_{1},\, y_{1}) denote the two endpoints.

The formula for the midpoint of these two points would be:

\displaystyle \left(\frac{x_{0} + x_{1}}{2},\, \frac{y_{0} + y_{1}}{2}\right).

(Similar to taking the average of each coordinate.)

In this question, it is given that x_{0} = 10 whereas y_{0} = 12. Substitute these two values into the expression for the coordinate of the midpoint:

  • x-coordinate of the midpoint: \displaystyle \frac{10 + x_{1}}{2} = 6.
  • y-coordinate of the midpoint: \displaystyle \frac{12 + y_{1}}{2} = 9.

Solve these two equations for x_{1} and y_{1}: x_{1} = 2 whereas y_{1} = 6.

Hence, the coordinate of the other point would be (2,\, 6).
