Find the equation of the graphed line.

Mathematics
1 answer:
Alex_Xolod [135]2 years ago
5 0

example: the line is y = ax + b

The line go through 2 points ( -4 ; 0 ) and ( 0 ; -2 )

So:

  • -2 = 0a + b => b = -2
  • 0 = -4a + (-2) => a = 2/-4 = -1/2

The line is y = -1/2x - 2 ( i'm not sure)

Answer: a

Ok done. Thank to me :>

Write the Recursive Rule for the sequence:
skad [1K]

A formula is recursive if it expresses the term a_n in terms of the previous one(s) a_{n-1},\ a_{n-2},\ \ldots,\ a_1

In this case, every term is 7 more than the previous one, so the formula for a_n will only involve a_{n-1}:

a_n = a_{n-1} + 7

In fact, this formula is simply saying: for every index n, the term with that index is 7 more than the term before.

Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is

a_n = a_{n-1} + 7,\quad a_1 = 2

which means: start with 2 and generate every other term by adding 7 to the previous one.

In the diagram, the length of segment BC is 23 units.
timurjin [86]

Both sides should be the same length..

Since we know that BC = 23 you need to find the value of x and put it in the formula.

23 = 2x+7

16 = 2x

x = 8

4x + 1 + 4(8) + 1 = 33 units

I quite don’t get this question and I have 4 minutes remaining
gregori [183]

The length of one of the sides of the larger pentagon is 24 cm. The length of one of the sides of the smaller pentagon is 8 cm.

24÷8=3

So, if the larger pentagon is 3x the size of the smaller pentagon, we can find the area of the smaller pentagon by dividing the area of the larger pentagon by 3.

135÷3=45

The area of the smaller pentagon is 45in²
