Luis is wrong because 8 to the third power is not 24, but is 512. He multiplied 8 by 3 instead of doing 8x8x8, so Luis made an incorrect claim.

Ok so Luis made an incorrect claim because you have S to the third is the formula they use in this problem and 24 wouldn't fit if 8 is going to the third power because 8 to the third power is equal to 512. In addition, since the math doesn't fit, its an incorrect explanation on how to find this answer. Hope I helped! If you have any questions, feel free to ask!

Answer:

B

Step-by-step explanation:

4x²/2 √x^4/4x²

2x²√x²/4  ( equal to C)

4x²/2(x²/2x)

2x²(x²/2x)=

2x^4/2x =x³ ( equal to A) or √x^6 ( equal to D) also E x²√x²=x^3

Write 1/3 x^2 - 4x + 17 in vertex form
Svetradugi [14.3K]

Answer:

f(x)=−4(x+ 41 ) 2 − 4 11

Explanation:

The given function is

f(x) = - 4 {x}^{2} - 2x - 3f(x)=−4x 2 −2x−3

To write the function is vertex form, we need to complete the square.

We first factor -4 to get:

f(x) = - 4 ({x}^{2} + \frac{1}{2} x) - 3f(x−4(x2 + 21 x)−3

Add and subtract the square of half the coefficient of x.

f(x) = - 4( {x}^{2} + \frac{1}{2} x + \frac{1}{16} ) - \frac{1}{4} - 3f(x)=−4(x 2 + 21 x+ 16 1 )− 41 −3

We factor the perfect square trinomial and simplify to get:

f(x) = - 4( {x + \frac{1}{4} )}^{2} - \frac{11}{4}f(x)=−4(x+ 41 ) 2 − 4 11

Put these fractions from smallest to greatest<br><br>6/5, 8/15, 1/4
valkas [14]
1/4, 8/15, 6/5
One way to figure this out is to divide the fractions and find which number is bigger
Or you should know 1/4= .25 , 8/15 is around half or .5 and 6/5  the numerator is larger than the denominator, so it would be bigger than 1 <span />

8. The straight line depreciation equation for a car is
kifflom [539]

An algebraic expression to represent the value of this car after M months is y=Mx+C.

We have given that the

The straight-line depreciation equation for a car is,

y = -2,680x + 26,800.

therefore after 4moths

y = -2,680(4) + 26,800.

y = -10720 + 26,800.

y=16080

<h3>What is the slope?</h3>

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as rise over run (change in y divided by change in x)

b. For find after the 75 months replace x by 75 and slolve the given inequality.

Suppose that M represents the length of time in months when

the car still has value.

An algebraic expression to represent the value of this car after M months.

y=Mx+C.
