PLS HELPPPP Write a linear equation in point slope form for the line that goes through (-1,3) and (1,-9) 15 pts

Answers

Answer 1
Answer:

Solution:

First find the slope

Slope=(y2-y1)/(x2-x1)\nSlope=((-9)-(3))/((1)-(-1))\nSlope = (-12)/(2)\nSlope=-6\n

Secondly, write the equation

y=m(x-xo)+yo\ny=-6(x-1)+(-9)\ny=-6x+6-9\ny=-6x-3

Answer:

y=-6x-3

Check:

(-1,3)\ny=-6(-1)-3\ny=6-3\ny=3

(1,-9)\ny=-6(1)-3\ny=-6-3\ny=-9

Hope this was helpful.

​What is the value of f(−2)?

f(−2) = ?

Answers

Answer:

f(- 2) = - 1

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x), that is

f(- 2) = 2(- 2) + 3 = - 4 + 3 = - 1

For 2^(x) + 3, then

f(- 2) = 2^(-2) + 3 = (1)/(4) + 3 = 3.25

If h(r) = 23r − 6, what is the value of h(-9)? Question 5 options: a) 0 b) 12 c) −623 d) -12

Answers

Answer:

-213

not in d option though check d question

Step-by-step explanation:

h(r) = 23r − 6

h(-9) = 23(-9) - 6

= -207 - 6

= -213

Answer:

-213

Step-by-step explanation:

If h(r) = 23r − 6, then, if we choose r = 2 as an example (only), then:

If h(2) = 23(2) − 6 = 46 - 6 = 40

Using the same approach, we substitute -9 for r, obtaining:

If h(-9) = 23(-9) − 6 = -207 - 6 = -213

Factor the given expression. 64^3-343

Answers

Your answer is 261201

63³-343 = 261801

Factor the following integer:

261'801

The sum of the digits of 261801 is 2 + 6 + 1 + 8 + 0 + 1 = 18, which is divisible by 9. This means 261801 is too.

261801 = 9×29089:

261801 = 9×29089

9 = 3^2:

261801 = 3^2×29089

Because 29089 is odd, only test odd numbers for divisibility.

29089 is not divisible by 3, 5, 7, 9, 11, 13, 15 or 17.

29089 = 19×1531 which means 29089 is divisible by 19:

261801 = 3^2×19×1531

3 is prime:

261801 = 3^2×19×1531

Because 19 is odd, only test odd numbers for divisibility.

19 is not divisible by 3.

Since 19 is not divisible by any integer up to 4, it is prime:

261801 = 3^2×19×1531

Because 1531 is odd, only test odd numbers for divisibility.

1531 is not divisible by 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39.

Since 1531 is not divisible by any integer up to 39, it is prime:

261801 = 3^2×19×1531

There are 2 copies of 3, 1 copy of 19 and 1 copy of 1531 in the product:

Answer: 261801 = 3^2×19×1531
