Step-by-step explanation:

STEP1:Equation at the end of step 1

(((2 • (x3)) + 32x2) - 6x) - 40

STEP 2 :

Equation at the end of step2:

((2x3 + 32x2) - 6x) - 40

STEP3:Checking for a perfect cube

3.1 2x3+9x2-6x-40 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 2x3+9x2-6x-40

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -6x-40

Group 2: 2x3+9x2

Pull out from each group separately :

Group 1: (3x+20) • (-2)

Group 2: (2x+9) • (x2)

Andre can run 5 miles in 40 minutes. At that rate of speed, how long would it take him to run 10 kilometers? Use the conversion

matrenka [14]

Answer:

50 minutes = B

Step-by-step explanation:

Andre can run 5 miles in 40 minutes

for 1 miles = 40/5 = 8 minutes

for 10 kilometres

1 mile = 1.61 kilometres

x = 10 kilometres

x= (10x1)/1.61= 10/1.61 = 6.21miles

for 1 miles = 40/5 = 8 minutes
6.21 miles = 8 x 6.21 = 49.689 minutes ≈ 50 minutes = B

Which of the following is the graph of y = negative 4 StartRoot x EndRoot? On a coordinate plane, an absolute value curve opens

Darya [45]

Answer:

see the procedure

Step-by-step explanation:

we have

$y=-4\sqrt{x}$

we know that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

In this problem

The domain for x is the interval [0,∞)

All real numbers greater than or equal to zero

The range for y is the interval (-∞,0]

All real numbers less than or equal to zero

The graph in the attached figure

therefore

On a coordinate plane, an absolute value curve opens down and to the right in quadrant 4 and starts at (0, 0)
