Let <em>x</em> and <em>y</em> be the two numbers.

Their sum is 140, so

<em>x</em> + <em>y</em> = 140

Twice the first number <em>x</em> is 2<em>x</em>. 5 more than this is 2<em>x</em> + 5. This is the value of the second number, so

<em>y</em> = 2<em>x</em> + 5

Substitute this into the first equation and solve for <em>x</em> :

<em>x</em> + (2<em>x</em> + 5) = 140

3<em>x</em> + 5 = 140

3<em>x</em> = 135

<em>x</em> = 135/3 = 45

Then

<em>y</em> = 2*45 + 5 = 95

makvit [3.9K]

Answer:

y = -2x - 2

Step-by-step explanation:

Given:

m = -2

Slope-intercept:

y - y1 = m(x - x1)

y + 8 = -2(x - 3)

y + 8 = -2x + 6

y = -2x - 2
