vesna_86 [32]3 years ago
7 0

Let's simplify step-by-step.

2(3x+5)−4(x−1)

Distribute:

=(2)(3x)+(2)(5)+(−4)(x)+(−4)(−1)

=6x+10+−4x+4

Combine Like Terms:

=6x+10+−4x+4

=(6x+−4x)+(10+4)

=2x+14

Answer:

=2x+14

What is the slope of the line going through the points (-3,-7.5) and (-2,-5)
lakkis [162]

Answer:

<em>2.5</em>

Step-by-step explanation:

y2 - y1 = top

x2 - x1 = bottom

<em>y2 = -5</em>

<em>y1 = -7.5</em>

<em />

<em>x2 = -2</em>

<em>x1 = -3</em>

<em />

<em />

-5-(-7.5) = 2.5

-2-(-3) = 1

2.5 over 1 = 2.5

What is the answer please.... need help
mina [271]

Answer:

f\left(x\right)=x^3-6x^2+3x+10 is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

f\left(x\right)=x^3-6x^2+3x+10

As the highest power of the x-variable is 3 with the leading coefficients of 1.

  • So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.

solving to get the zeros

f\left(x\right)=x^3-6x^2+3x+10

0=x^3-6x^2+3x+10              ∵  f(x)=0

as

Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0

so

\left(x+1\right)\left(x-2\right)\left(x-5\right)=0    

Using the zero factor principle

if  ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)

x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0

x=-1,\:x=2,\:x=5

Therefore, the zeros of the function are:

x=-1,\:x=2,\:x=5

f\left(x\right)=x^3-6x^2+3x+10 is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.
