Answer:

Common difference(d) states that the difference between the two consecutive term of the arithmetic sequence

Given the sequence:

9, 2.5, -4, -10.5, -17

This is the arithmetic sequence with common difference

i.e, d = -6.5

Since,

2.5 - 9 = -6.5

-4-2.5 = -6.5

-10.5 -(-4) = -10.5 + 4 = -6.5

-17 + 10.5 = -6.5

Therefore, the common difference between successive terms in the given sequence is, -6.5

Common difference, d = 2.5 - 9 = -4 - 2.5 = -6.5

Common difference = -6.5

PLEASE HELP! urgent! Write the equation of a line in a slope-intercept form and standard form

m_a_m_a [10]

Answer:

$y = \frac{3}{4}x -3$ --- Slope intercept

$4y - 3x =- 12$ --- Standard form

Step-by-step explanation:

Given

The attached linear graph

Required

The equation

Select any two points on the line

$(x_1,y_1) = (0,-3)$

$(x_2,y_2) = (4,0)$

Next, calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

So, we have:

$m = \frac{0 --3}{4 - 0}$

$m = \frac{3}{4}$

The slope intercept is then calculated using:

$y = m(x - x_1) + y_1$

So, we have:

$y = \frac{3}{4}(x - 0) -3$

$y = \frac{3}{4}(x) -3$

$y = \frac{3}{4}x -3$

Multiply through bu 4

$4y = 3x - 12$

Subtract 3x from both sides

$4y - 3x =- 12$ --- Standard form

What is the average rate of change of y with respect to x over the interval [-3, 4] for the function y = 2x + 2

Ksenya-84 [330]

Answer:

y = 2x + 10

Step-by-step explanation:

y1 = 4

x1 = -3

slope,m = 2

y - y1 = m(x - x1)

y - 4 = 2(x + 3)

y - 4 = 2x + 6

y = 2x + 10

Question 2 The length of a rectangle is 5 yd more than twice the width, and the area of the rectangle is 63 yd2 . Find the dimen

Sedaia [141]

<span>L = 2W + 5
A = LW = 63
L = 63/W
W=63/L

L = 2W + 5
63/W = 2W + 5
63 = 2WW + 5W
2WW + 5W - 63 = 0

2WW + 5W - 63 = 0
is already in quadratic equation form: ax^2 + bx + c = 0

use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a

the two solutions are:
x = 9/2
x = -7
you cant have a negative solution for length so use the positive one

solve for length:
L=5+2(9/2)
L=5+18/2
L=5+9
L=14

W = 9/2
L = 14</span>
