Answer:

x = (13) ^ 1/3

x is approximately 2.351334688

Step-by-step explanation:

x^3 + 7 = 20

Subtract 7 from each side

x^3 + 7-7 = 20-7

x^3 = 13

Take the cube root of each side

x^3 ^ 1/3 = (13) ^ 1/3

x = (13) ^ 1/3

x is approximately 2.351334688

Answer:

x = ∛13 = 2.35 to the nearest hundredth.

Step-by-step explanation:

x^3 + 7 = 20

x^3 + 7 - 7 = 20 - 7

x^3 = 13

x = ∛13.

How do I solve part A

seraphim [82]

Answer:

The solution of this expression is $x_{1} = -1$ and $x_{2} = -\frac{1}{2}$ .

Step-by-step explanation:

The procedure for solution of exercise A is described below:

1) We expand the expression.

2) The resulting expression is rearranged into the form of a second order polynomial.

3) Roots are found by Quadratic Formula.

Step 1:

$2\cdot x \cdot (x+1.5) = -1$

$2\cdot (x^{2}+1.5\cdot x) = -1$

$2\cdot x^{2} + 3\cdot x = -1$

Step 2:

$2\cdot x^{2}+3\cdot x +1 = 0$

Step 3:

$x_{1, 2} = \frac{-3\pm \sqrt{3^{2}-4\cdot (2)\cdot (1)}}{2\cdot (2)}$

$x_{1,2} = -\frac{3}{4}\pm \frac{1}{4}$

$x_{1,2} = \frac{-3\pm 1}{4}$

The solution of this expression is $x_{1} = -1$ and $x_{2} = -\frac{1}{2}$ .

A line has a slope of -2/3 and passes through the point (-3, 8). What is the equation of the line?

dexar [7]

Answer:

y= -2/3x+6

Step-by-step explanation:

Using slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = -2/3x +b

Substitute the point into the equation

8 = -2/3(-3) +b

8 = 2+b

8-2 =b

6=b

y= -2/3x+6

1. GRIDDED RESPONSE What is the slope of the line that

Morgarella [4.7K]

Answer:

slope = $\frac{5}{12}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (10, 6)

m = $\frac{6-1}{10+2}$ = $\frac{5}{12}$
