Which polynomials are in standard form

1 answer:

Mama L [17]3 years ago

Answer:

The second option, x^4 - 8x^2 - 16.

Step-by-step explanation:

Polynomials in standard form start with the highest degree, from greatest to least exponent. After all terms with exponents are in order, alphabetical variables are next. In this case there's only x. Last are constant terms, which are by itself, with no variable next to it/an exponent to the right of it.

x^4 - 8x^2 - 16 is in standard form because it follows the criteria above. 4 is the highest degree since it's the highest exponent in the polynomial expression, which is why it starts off with x^4. Other terms with lesser exponents are next. In this case, it's 8x^2 with the less exponent of 2. Finally, it ends with your constant term, -16.

Solve the inequality 2(4x-3)>-3(3)+5x

Sholpan [36]

Answer:

$x > -1\\$

Step by step explanation:

$~~~~~2(4x-3) > -3(3)+5x\\\\\implies 8x-6 > -9+5x\\\\\implies 8x > -9+6+5x\\\\\implies 8x > -3+5x\\\\\implies 8x -5x > -3\\\\\implies 3x > -3\\\\\implies x > -\dfrac 33\\\\\implies x > -1$

Help! I will mark you the brainest !! ☺️☺️

Marizza181 [45]

Answer:

Part 1) $0.675\%$

Part 2) $475\%$

Part 3) $8\%$

Part 4) $\frac{67}{20}$

Part 5) $2.65$

Step-by-step explanation:

Part 1) Write as a percent 0.00675

we know that

To write a number as a percent, multiply the number by 100

so

$0.00675*100=0.675\%$

Part 2) Write as a percent 4 3/4

Convert mixed number to an improper fraction

$4\frac{3}{4}=\frac{4*4+3}{4}=\frac{19}{4}$

we know that

To write a fraction as a percent, multiply the fraction by 100

$\frac{19}{4}*100=19*25=475\%$

Part 3) Write as a percent 2/25

we know that

To write a fraction as a percent, multiply the fraction by 100

$\frac{2}{25}*100=2*4=8\%$

Part 4) write as a fraction 335%

we know that

$335\%=\frac{335}{100}$

Simplify

Divide by 5 both numerator and denominator

$\frac{335}{100}=\frac{67}{20}$

Part 5) Write as a decimal 265%

we know that

$265\%=\frac{265}{100}=2.65$

Which is the graph of linear inequality 6x + 2y > –10?..

Sauron [17]

Answer:

Step-by-step explanation:

$6x+2y>-10\qquad\text{subtract 6x from both sides}\\\\2y>-6x-10\qquad\text{divide both sides by 2}\\\\y>-3x-5$

Change the inequality symbol to the symbol of equation.

$y=-3x-5$

Choice any two values of x and calculate the values of y:

for x = 0

$y=-3(0)-5=0-5=-5\to(0,\ -5)$

for x = -2

$y=-3(-2)-5=6-5=1\to(-2,\ 1)$

Draw the line passing through the given points.

If is < or >, then plot the dot line.

If is ≤ or ≥, then plot the solid line.

We have the sign of an inequality ">". Therefore plot a dot line.

Now shading.

If is < or ≤, then shading to the left.

If is > or ≥, then shading to the right.

We have the sign of an inequality ">'. Therefore shading to the right.
