Using an absolute-value inequality, describe the set of numbers whose distance from 4 is greater than 5 units. Draw a graph of this set on a number line. Finally, describe this set of numbers using inequalities without absolute value signs.

Y = -2x^2

h = Xv = -B/2A = 0/-4 = 0.

k = -2*0^2 = 0.

V(0,0).

Use the following points for graphing:

Y = -2x^2.

(x,y)

(-2,-8)

(-1,-2)

V(0,0)

(1,-2)

(2,-8)

Y = -2x^2 + 4.

h = Xv = -B/2A = 0/-4 = 0.

k = Yv = -2*0^2 + 4 = 4.

V(0,4).

(-2,-4)

(-1,2)

V(0,4)

Answer:

D

Step-by-step explanation:

(z + 6)(2z² + 3z + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

z(2z² + 3z + 5) + 6(2z² + 3z + 5) ← distribute parenthesis

= 2z³ + 3z² + 5z + 12z² + 18z + 30 ← collect like terms

= 2z³ + 15z² + 23z + 30

Answer:

Option A, y = -1/3x + 2

Step-by-step explanation:

Step 1:  Determine the equation

Looking at the graph we can see that the line will intersect the y-axis at around 2 units which eliminates options B and D.  Now, looking at the slope of the graph we see that it's going in a downward trend which means that the slope is negative.  That eliminates option C which leaves us with the only option of A.

Answer: Option A, y = -1/3x + 2

Answer:

Step-by-step explanation:

cube of four is 64 and cube of 5 is 125

Answer:

4 / 5

Step-by-step explanation:

∛( 64 / 125 )

= ∛64 / ∛125

64 can be simplified as 4 x 4 x 4.

∛64

= ∛ ( 4 x 4 x 4 )

= 4

125 can be written as 5 x 5 x 5.

∛125

= ∛ ( 5 x 5 x 5 )

= 5

∛ ( 64 / 125 ) = 4 / 5

Answer:

Step-by-step explanation:

I'm not sure man try asking a tutor

Answer:

let's see....

lil info about elimination method:

it has to do with elimination of an entire value and coefficients meaning to get rid of them entirely! so to do that you must have two identical values.

look at -6 in the first equation and the other -6 below it in the second equation.

if you have something like that, then just look for a symbol like - or + that will eliminate them

so we use the - (minus) sign and just subtract the first equation from the second, you would get -x =2.

so x cannot be negative...

so x = -2.

( Incase the numbers aren't the same, you have to do something to make the numbers same but if you have it like that up⬆️ then just use the symbol that would eliminate those same numbers to give you x immediately)

Have a nice day!

Answer:

Step-by-step explanation:

6x + 8y = 13

8y = 13 - 6x

y = (13 - 6x) / 8

f(x) = (13 - 6x) / 8

x = (13 - 6f^-1(x)) / 8

8x = 13 - 6f^-1(x)

6f^-1(x) + 8x = 13

f^-1(x) = (13 - 8x) / 6

Answer

12x-9x-45 (put a 2 above the x on the 12)

Step-by-step explanation:

(2x-9)(x+5)

2x(x) = 2x

2x(5) = 10x

-9(x) = -9x

-9(5) = -45

2x^2+10x^2-9x-45

2x^2+10x^2 = 12x^2

12x^2-9x-45

Using the t-distribution, as we have the standard deviation for the sample, the 95% confidence interval is (71.63, 84.36).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 4 - 1 = 3 df, is t = 3.1824.

The parameters are given as follows:

[tex]\overline{x} = 78, s = 10, n = 4[/tex]

Hence, the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 78 - 3.1824\frac{10}{\sqrt{4}} = 71.63[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 78 + 3.1824\frac{10}{\sqrt{4}} = 84.36[/tex]

The 95% confidence interval is (71.63, 84.36).

The Total Interest Combine will be interest from the compounded invesestment and that of the simple interest investement $13,974.54 plus $13,848.00 which is 27 822.54 US$

Given Data

Calculation For Compound Interest:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.2/100

r = 0.022 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 12,000.00(1 + 0.022/1)(1)(7)

A = 12,000.00(1 + 0.022)(7)

A = $13,974.54

Calculation For Simple Interest:

First, converting R percent to r a decimal

r = R/100 = 2.2%/100 = 0.022 per year.

Solving our equation:

A = 12000(1 + (0.022 × 7)) = 13848

A = $13,848.00
