(4x^5 + 3x^2 – x^4) +(6x^2 - 2x^5)

Monica [59]

Answer:

The simplified equation is as follows 2x^5 -x^4 + 9x^2

Step-by-step explanation:

Remove the parentheses around each equation and pair like exponents together

4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2

Then combine the like terms

2x^5 - x^4 + 9x^2

It is in that order due to the proper form being to go from the highest to lowest exponents in an answer

PLEASE HELP ASAP PLEASE

Bond [772]

Answer:

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R

Step-by-step explanation:

So there ya go

D=R

and now bout the range ya gotta find the vertex, which is:

$x = \frac{ - b}{2a} \: \: y = \frac{Δ}{4a}$

now pay attention

X=2/–2=–1

y=–(–1)²–2(–1)+3=4

Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]

Well, finally your answer is D

Explain how to determine if the triangle is an isosceles? Use algebraic formulas to SHOW

lorasvet [3.4K]

Answer: Hope This Helps!

Step-by-step explanation:

Use the distance formula to calculate the side length of each side of the triangle. If any 2 sides have equal side lengths, then the triangle is isosceles.

More precise info: Given the coordinates of the triangle's vertices, to prove that a triangle is an isosceles plot the 3 points (optional) use the distance formula to calculate the side length of each side of the triangle. If any 2 sides have equal side lengths, then the triangle is isosceles.

Marine fuel is a combination of gasoline and motor oil. The standard gasoline and oil mixture is about 98% gasoline and about 2%

Georgia [21]

Answer:

0.98g+ 0.02m= 7.1224 gallons standard mixture

0.96g+ 0.04m= 6.25 gallons break oil

3.92 gallons of gasoline is required for 4 gallons the standard mixture

Step-by-step explanation:

If we have to use 6 gallons of gasoline this means that 98%= 6 gallons and 2% would be 6/98*2

Gasoline: Motor oil

6 : x

98 : 2

Using the product rule

x= 6*2/98= 0.1224 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the standard oil the equation would be

0.98g+ 0.02m= 7.1224 gallons standard mixture

For break in oil

Gasoline: Motor oil

6 : x

96 : 4

Using the product rule

x= 6*4/96= 0.25 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the break oil the equation would be

0.96g+ 0.04m= 6.25 gallons break oil

Part b. For 4 gallons of the "break in" mixture

96% of the 4 gallons of the "break in" mixture is gasoline = 3.84 gallons of gasoline

4% of 4 = 0.16 gallons of motor oil

Now the standard mixture 4 gallons would contain 98 % of gasoline and 2 % of motor oil

98% of 4 gallons= 3.92 gallons of gasoline

2% of 4 gallons= 0.08 gallons of motor oil.
