−2/ 3 x−1+1≤1+1

−2/ 3 x≤2

PLEASE HELP (15 POINTS!!) PLEASE ​

Answers

Answer:

(4,9)

Step-by-step explanation:

To solve this, you can use substitution or elimination. In this case I would use substitution. To do this, you have to isolate a variable. x is already isolated so we can skip this step. plug x into 5x-7y=-43. This will make the equation 5(2y-14)-7y=-43. Simplify this to get 10y-70-7y=-43. Simplify this to get 3y-70=-43. Add 70 in both sides to isolate y. This will make the equation 3y=27. Divide both sides by 3 to make y equal to 1. This will make the equation y=9. Now you know that y=9. Plug 9 into any equation. x=2(9)-14. Simplify this to get x=18-14. x=4. Now put the numbers as an ordered pair which is (x,y). We know that x=4 and y=9 so it is (4,9).

A man drops a ball from the top of a 300 foot cliff. The height of the falling ball is modeled
by h(t)=-16t2+300 where h is in feet and t is in seconds. How long does it take for the ball to be 44 feet above the ground?

Answers

Answer:

The ball reaches 44 ft above the ground after 4 sec.

Step-by-step explanation:

Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t.  Indicate exponentiation with " ^ "

-16t^2 + 300 = 44 becomes

-16t^2 + 256 = 0, or 16t^2 = 256.  Then, taking the square root of both sides, we get:

4t = 16, or t = 4 sec.  The ball reaches 44 ft above the ground after 4 sec.

The ball will take 4 seconds.

What are quadratic equations?

A quadratic equation, or simply "quadratics," is a polynomial equation with a degree of two as its highest. This is how it is expressed:

a x² + b x + c = 0 where x is the unknown variable and the constant terms are a, b, and c.

Given equation of height h(t) = -16t² + 300...…..(1)

where h is height in feet and t is time in seconds,

and height at t = 0 is 300 feet

when ball is 44 feet above ground then time is,

put h = 44 in equation 1

44 = -16t² + 300

16t² = 300 - 44

t² = 256/16

t = √16

t = 4

Hence time taken by ball is 4 seconds.

primero debemos resolver la ecuacion  sumamos 3d mas 10d luego pasamos el mumero 8 al otro lado entonces se convertira en negativo 8 el resulatdo de esta ecuacion sera 13d elevado al cubo =-8

13d^{3}=-8 entonces

entonces remplazamos en la formula cuadratica 3d=a  0=b  -8=c y lo rremplazas en la formula cuadratica

Step-by-step explanation:

First we must solve the equation we add 3d plus 10d then we pass the number 8 to the other side then it will become negative 8 the result of this equation will be 13d cubed = -8

13d 3 = - 8 then

then we replace in the quadratic formula 3d = a 0 = b -8 = c and you replace it in the quadratic formula

Answers

Answer:

38

Step-by-step explanation:

The area of a kite is equal to half the product of the diagonals

To find the area we must first find the measures of the diagonals

short diagonal = 2 + 2 = 4

longer diagonal = 8 + 11 = 19

We then calculate the area by multiplying the two diagonals together and then dividing that by 2

A = 19 * 4 = 76

76 / 2 = 38

Hence, the area of the kite is 38m²

38m².

Answer:

Solution given;

diagonal 1=8+11=19m

diagonal 2=2+2=4m

the area of a kite =½*diagonal 1*diagonal 2

=½*4*19=38m²

The area of kite is 38.

Answers

Answer:

–9(3x³ – 8x + 9)

Step-by-step explanation:

–27x³ + 72x – 81

The above equation can be factorised as follow:

–27x³ = –3 * 3 * 3 * x * x * x

72x = 2 * 2 * 2 * 3 * 3 * x

–81 = –3 * 3 * 3 * 3

Common factor = 3 * 3

Greatest common factor = 9

Thus,

–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)

–27x³ + 72x – 81 = –9(3x³ – 8x + 9)

The first three terms of arithmetic progression are -5,-1 and 3.Find the six term.​

Answers

Answer:

15

Step-by-step explanation:

The pertinent general formula for this arithmetic progression is

a(n) = a(1) + d(n - 1), where d is the common difference.  That difference is d = 4.

Here, a(n) = -5 + 4(n -1)

Therefore, a(6) = -5 + 4(5) = 15

Answer:

It is 15.

Step-by-step explanation:

Alright, first lets find the pattern. Since its a arithmetic sequence, it has something to do with adding/subtracting.

With the values, -5, -1, and 3. Notice something about them? -1 is 4 more than -5 & 3 is 4 more than -1. There's a pattern! The pattern is that for every new term, it is 4 more than the one before it.

With this, we can make a table to find the 6th term!

(Given)

1st Term: -5

2nd Term: -1

3rd Term: 3

Now, continue adding 4 to each term...

4th Term: 7

5th Term: 11

6th Term: 15

For the 6th term, it has been found that the answer's 15.

Log (1/x) = –0.9925

Step-by-step explanation:

From the question given above, the following data were obtained:

Log x = 0.9925

Log (1/x) =?

Recall,

Log (M/N) = log M – Log N

Thus,

Log (1/x) = Log 1 – Log x

Recall

Log 1 = 0

Log x = 0.9925

Thus,

Log (1/x) = Log 1 – Log x

Log (1/x) = 0 – 0.9925

Log (1/x) = –0.9925
