Find the slope-intercept form of the equation of the line passing through the given points. (1, 1), (7, − 1 4 )

1 answer:

6 0

Slope = (-14-1)/(7-1) = -15/6

y = mx + c
y = -15/6 x + c
at (1,1)
1 =-15/6(1) + c
c = 1 + 15/6 = 21/6

y = -15/6 x + 21/6 or
6y = -15x + 21

-Dominant- [34]

Step-by-step explanation:

- 3 ( x + 2 ) + 9 + 7x = 4x + 5 - 2

- 3x - 6 + 9 + 7x = 4x + 5 - 2

- 3x + 7x + 9 - 6 = 4x + 5 - 2

17-5(2×-9)=-(-6×+10)+4 Please help me with this problem

uranmaximum [27]

Answer:

x = 17/4 = 4.25

Step-by-step explanation:

We assume your multiplication symbol (×) is intended to be a variable (x).

Simplifying, we have ...

17 -10x +45 = 6x -10 +4

68 = 16x

68/16 = x = 17/4 = 4.25

Check

17 -5(2(4.25) -9) = -(-6(4.25) +10) +4

17 -5(8.50 -9) = -(-25.5 +10) +4

17 -5(-0.5) = 15.5 +4

17 +2.5 = 19.5 . . . . . . true

What is the value of a3 in the sequence? a3 the 3 is squared below of a

kkurt [141]

Answer:

Option D is correct.

$a_3 = \frac{-1}{2}$

Step-by-step explanation:

The sequence is in the form of :

$a_1, a_2, a_3, a_4, .......$

where

$a_1$ represents the First term.

$a_2$ represents the Second term.

$a_3$ represents the Third term.

$a_4$ represents the Fourth term and so on.....

we have to calculate the $a_3$ in the given sequence:

Given the sequence: $-4 , -2, -\frac{1}{2} , -\frac{1}{4}, ......$

$a_3 = \frac{-1}{2}$

Therefore, the third term $a_3 = \frac{-1}{2}$
