Answer B.
- 3 {x}^{2} (5x - 4 {x}^{2} - 6) \\  =  - 15 {x}^{3}  + 12 {x}^{4}  + 18 {x}^{2}  \\  = 12 {x}^{4}  - 15 {x}^{3}  + 18 {x}^{2}

Answer:

The answer is B

Step-by-step explanation:

(−3x2)(5x−4x2−6)

=(−3x2)(5x+−4x2+−6)

=(−3x2)(5x)+(−3x2)(−4x2)+(−3x2)(−6)

=−15x3+12x4+18x2

=12x4−15x3+18x2

Answer:

y-5=5/4(x-1)

Step-by-step explanation:

the slope is 1.25

m=y2-y1/x2-x1=10-5/5-1=5/4=1.25

y-5=(5)/(4)(x-1)=

y=(5)/(4)x+(15)/(4) this one is linear

it is a linear function and the

Answer:

yes it is possible to get a common denominator grater than 12 and still get the right answer.

Step-by-step explanation:

Write the equation of the line, given the y and x-intercepts:
kolezko [41]

Answer:

The answer to your question is:                161x + 17y - 391 = 0

Step-by-step explanation:

Data

y-intercept = 23         Get the points      (0, 23)

x- intercept = 4.75                                   (4.75, 0)

                      4.75 = 17/4                         (17/4, 0)

slope

              m = (y2 - y1) / (x2 - x1)

              m = (0 - 23) / (17/4 - 0)

              m = -23 / 17/4

             m = - 161 / 17

equation

              (y - y1) = m (x - x1)

              ( y - 23) = -161 / 17 (x - 0)

               y - 23 = -161/17 x

              17(y - 23) = -161x

              17y - 391 = -161x

              161x + 17y - 391 = 0
