slope-intercept form:

y = 2x + 7

Point-slope form:

y - 9 = 2( x - 1 )

I'm not 100% sure on the point slope form but try it for now.

point slope form

y-y1 = m(x-x1)

y-9 = 2(x-1)


change to slope intercept form

y-9 = 2(x-1)

distribute

y-9 = 2x-2

add 9 to each side

y = 2x-2+9

y = 2x+7

Answer:

(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.

Can't read the second question fully.

(A) 0.53

Step-by-step explanation:

Number 1:

If we have the equation 3x + 2 = 5x, our first goal is to get rid of the x term on one side.

To do this we can subtract 3x from both sides. This leaves our equation to 2=2x. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x.  This leaves x=1.

<em>I couldn't read Number 2 fully - I'm sorry :c</em>

<em></em>

Number 3:

Given the equation 3(x+0.2)=2.2, we want to isolate x on one side.

To do this, we first apply the distributive property to the left side.

3x + 0.6 = 2.2

Now subtract 0.6 from both sides:

3x=1.6

And divide both sides by 3.

x=0.5\overline{3}

This rounds to 0.53.

Hope this helped!

Answer:

Sum angle of triangle BHD = 180°

36 + 39 + BHD = 180

BHD = 180 - 36 - 39

= 105°

BHD + x° = 180° (straight angle)

105° + x° = 180°

x = 180 - 105

= 75°
