Answer:

y = 4x +1

Step-by-step explanation:

6x + 1 = y + 2x

First you need to solve for y, so then you need to

1. Combine like terms

So since there isn't anything to combine we can more on.

2. Make Y by itself

You need to subtract the 2x from both side to get the answer

Simplify the expression-3÷(-2/5)

BARSIC [14]

Answer:

15/2 or 7.5

Step-by-step explanation:

-3÷ (-2/5)

The reciprocal of -2/5 is -5/2

So we multiply -3 into the reciprocal of the fraction and we can get the same answer

Therefore,

-3÷(-2/5)

= -3x -5/2

= (-5x-3)/2

(Two negatives become a positive)

= 15/2 in fraction form

And 7.5 in decimal form

Use Pascal's Triangle to determine the second term of the expansion of (x - 2)^5

goldfiish [28.3K]

Pascal's triangle up to the 5th iteration is

$\begin{array}{cccccc}1\\1&1\\1&2&1\\1&3&3&1\\1&4&6&4&1\\1&5&10&10&5&1\end{array}$

This tells us

$(x-2)^5=\boxed{1}x^5(-2)^0+\boxed{5}x^4(-2)^1+\boxed{10}x^3(-2)^2+\boxed{10}x^2(-2)^3+\boxed{5}x^1(-2)^4+\boxed{1}x^0(-2)^5$

so the second term in the expansion is

$5x^4(-2)^1=\boxed{-10x^4}$

On a map 0.75 inch represents 80 miles. Two cities that are 1025 miles apart will be how far apart on a map round to nearest ten

icang [17]

The cities are 9.6 inches apart on map.

Step-by-step explanation:

Given,

80 miles in actual = 0.75 inch

1 mile = $\frac{0.75}{80}\ inch$

Distance between two cities = 1025 miles

1025 miles on map = $1025*\frac{0.75}{80}\\$

$1025\ miles\ on\ map=\frac{768.75}{80}\\\\1025\ miles\ on\ map=9.6\ inches$

The cities are 9.6 inches apart on map.
