Answer:

d = 5

Step-by-step explanation:

an = 5n -3

a1 = 5 -3 = 2

a2 = 5*2 -3 = 10 - 3 = 7

d = a2 - a1 = 7 - 2 = 5

Answer:

Hi here is your answer

an=5n-3

an-1= -3+5n

an-1= -3+5(n-1)

an-1= -3+5n-5

an-1= 5n-7

d= an- an-1

d=(5n-3)-(5n-7)

d=5n-3-5n+7

d=4

Answer: d = 4

Hope this helps you.

Write the equation of a line that is parallel to {y=-\dfrac{5}{4}x+7}y=− 4 5 ​ x+7y, equals, minus, start fraction, 5, divided b
AlladinOne [14]

Write the equation of a line that is parallel to y=-5/4x + 7

Any line parallel to the given line will have the same slope. In an equation presented in the y-intercept form, the slope is always the coefficient of "x". In this case, the slope is -5/4 (meaning the next point is down 5, and 4 to the right).


Our equation so far looks like this: y = -5/4x + b

"b" represents the y-intercept. To solve for be, we will need to substitute values into x and y. The next piece of information it gives us is one of the points, or solutions, of the line. This means that since this point is on the line, we can use its x and y values to substitute.


x = -4

y= 1

y = -5/4x + b

1 = -5/4(-4) + b

1 = 5 + b

-4 = b


Final Answer: y = -(5/4)x -4

Why is water not used as a solvent in paper chromatography​
Anastaziya [24]

Answer:

Because the kind of compounfds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.

Over the summer, for every 14 Okra seeds Dana planted, 9 plants grew. If he planted 182 seeds, how many grew into plants?
vova2212 [387]
Simple...

you have: For every 14 seeds that Okra seeds Dana planted 9 of them grew; if he planted 182 seeds..how many grew?

Set up an equation...

\frac{9}{14} = \frac{x}{182}

Cross multiply....

14*x=14x

9*182=1638

14x=1638

\frac{14x}{14} = \frac{1638}{14} =117


x=117

This means that, for 182 seeds planted, 117 of them grew to be plants.

Thus, your answer.
