Answer:

-4*(x^2) - 2*x + 6

Step-by-step explanation:

= 2x^2+(4x-6x^2)+9-(6x+3)

= 2*(x^2) + 4*x - 6*(x^2) + 9 - 6*x - 3

= 2*(x^2) - 6*(x^2) + 4*x - 6*x + 9 - 3

= -4*(x^2) - 2*x + 6

Answer:-4*(x^2) - 2*x + 6

Step-by-step explanation:

from both sides first

= 2x^2+(4x-6x^2)+9-(6x+3)

= 2*(x^2) + 4*x - 6*(x^2) + 9 - 6*x - 3

= 2*(x^2) - 6*(x^2) + 4*x - 6*x + 9 - 3

                                                  = -4*(x^2) - 2*x + 6

H(x)=1/8x^3-x^2<br><br> Over which interval does h have a positive average rate of change?
lara31 [8.8K]

Answer:

(-\infty,0)\cup(\frac{16}{3},\infty)\\That \ is x\frac{16}{3}

Step-by-step explanation:

h(x)=\frac{1}{8}x^{3} -x^{2} \\\\Differentiate \ h(x) \ with \  respect \ to \ x\\h'(x)=\frac{3}{8}x^{2} -2x

For positive rate of change h'(x)>0

\frac{3}{8} x^{2} -2x>0\\x(\frac{3}{8}x-2)>0\\\\ When \ x0 \ (multiplication \ of \ two \ positives \ is \ positive)\\\\h'(x)>0 \ when \ x\frac{16}{3} \\\\

Answer?????????????????
ANTONII [103]
So the angle A on the first diamond corresponds with angle Q, angle B with angle S, angle C with angle R, and angle D with angle P. So if angle D correspond (equals) angle P then x+34=97 and if angle R corresponds with C then 3y-13=83. From there just do some basic algebra to find the x and y values.

What is a number that multiplies a variable in a term ?
kirill [66]
<h3>A number that multiplies a variable in a term is known as a coefficient.</h3>

Given the term: 6x^3, we can identify three parts:

The coefficient, 6, is the constant that is being multiplied by the variable.

The variable, x, is a number with an unknown value, or with multiple potential values.

The exponent, 3, is the power with which the variable is being raised to.

Two lines, A and B, are represented by the following equations:
ch4aika [34]
Line A: 2x+2y=8     ⇒2y=-2x+8  ⇒ y=-x+4
Line B: x+y=3          ⇒y=-x+3

Therefore: y=y then:
-x+4=-x+3
-x+x=3-4
0≠-1    ⇒There is no solution because the lines are parallels

Answer: There is no solution
