Which equation of a line contains the points (-10,15) and (8, -3) and is parallel to y +4= -(x - 1)?​
JulijaS [17]

Answer:

y= -x+5

Step-by-step explanation:

<em>The</em><em> </em><em>slop</em><em>e</em><em> </em><em>of</em><em> </em><em>th</em><em>e</em><em> </em><em>two</em><em> </em><em>paral</em><em>lel</em><em> </em><em>lin</em><em>es</em><em> </em><em>is</em><em> </em><em>equ</em><em>al</em>

<em>so</em><em>,</em><em> the</em><em> slope</em><em> of</em><em> </em>

<em>y</em><em>=</em><em>-x-3</em><em> </em><em>is</em><em> </em><em>-</em><em>1</em><em> </em>

<em>slo</em><em>pe</em><em>=</em><em>y2-y1</em><em>/</em><em>x2-x1</em><em>=</em><em>-</em><em>3</em><em>-</em><em>1</em><em>5</em><em>/</em><em>8</em><em>-</em><em>-</em><em>1</em><em>0</em><em>=</em><em>-</em><em>1</em>

<em>the</em><em> </em><em>equa</em><em>tion</em><em> </em><em>of</em><em> </em><em>t</em><em>he</em><em> </em><em>line</em><em> </em><em>i</em><em>s</em>

<em>y-15</em><em>=</em><em> </em><em>-</em><em>1</em><em>(</em><em>x--10</em><em>)</em>

<em>y</em><em>=</em><em> </em><em>-x-10</em><em>+</em><em>1</em><em>5</em>

the sum of a whole number A and a whole number B is 16, and the ratio A: B is equivalent to 5: 3. Find A and B.
Cerrena [4.2K]

Answer: A is 10; B is 6

Step-by-step explanation:

Let the sum of a whole number A and a whole number B = 16

A + B = 16

The ratio A: B = 5: 3

Possible whole numbers whose ratio gives 5 : 3 are 10 and 6, 15 and 9, 20 and 12 etc. However, since A + B must equal 16, only 10 and 6 fulfil the condition

So, let A be 10, while B is 6

10 + 6 = 16

The ratio 10 : 6 = 10/6 = 5/3

Thus, the value of A is 10; while B is 6
