Answer:

Step-by-step explanation:

He added 42 to both sides of the equation. What that did is eliminated 42 on the left and changed the value on the right. Now what he has is the unknown on the left and an integer on the right.

What is the equation of the line that passes through the points (–12, –8) and (–17, –16)?
horsena [70]

Answer:

<em>firstly</em><em> find</em><em> the</em><em> gradient</em><em> given</em><em> by</em><em> the</em><em> equation</em>

<em>m=</em><em>y2-y1</em><em>/</em><em>x2-x1</em>

<em>in this </em><em>case</em><em> </em><em>x1 </em><em>is </em><em>-</em><em>1</em><em>2</em><em>,</em><em>x2 </em><em>is </em><em>-</em><em>1</em><em>7</em><em>,</em><em> </em><em>y1 </em><em>is </em><em>-8 </em><em>and </em><em>y2 </em><em>is</em><em>-</em><em>1</em><em>6</em>

<em>m=</em><em>-</em><em>1</em><em>6</em><em>+</em><em>8</em><em>/</em><em>-</em><em>1</em><em>7</em><em>+</em><em>1</em><em>2</em>

<em> </em><em> </em><em> </em><em>=</em><em>-</em><em>8</em><em>/</em><em>-</em><em>5</em><em> </em><em>or1.</em><em>6</em>

<em>then</em><em> </em><em>use </em><em>the </em><em>equation</em>

<em>y-y1</em><em>=</em><em>m(</em><em>x-x1</em><em>)</em>

y+8=1.6(x+12)

y+8=1.6x+19.2

y=1.6x+11.2

I hope this helps and sorry if it's wrong

How do I find b of the traingal​
V125BC [204]

Answer:

Pythagorean Theorum:

16ft

Step-by-step explanation:

pythagorean theorum states a^2+b^2=c^2

it only works for right triangles, c is the hypotenuse, a and b are the legs

so to find b we plug in the info we have!

7.8^2+b^2=17.8^2

next we simplify:

60.84+b^2= 316.84

subtract 60.84 from both sides to isolate the variable:

b^2=256

square root both sides

b=16

16ft is the answer

I hope this helps!
