<span>First we have to determine the slope of each lines by transforming to the slope-intercept form:
y=(3x-7/)4; m2= ¾y=(12x+6)/5, m3 = 12/5
The formula to be used in the proceeding steps is a=tan^-1(m1-m2)/1+m1m2=tan^-1(m1-m2)/1+m1m2
substituting, a=tan^-1(m1-3/4)/1+3m1/4=tan^-1(m1-12/5)1+12m1/5) =>(4m1-3)/(4+3m1)=(5m1-12)/(5+12m1)m1 = -1applying this slope
y -y1 = m(x-x1)
when y1 = 5 and x1 = 4 then,
y - 5 = -1(x-4)
y = -x +4+ 5 ; y = -x +9</span>
Answer: Value of B= 75 Basketball cards
Step-by-step explanation:
STEP 1
let number of cards Steve has be =a
let number of cards Claire has be =b
STEP 2
Steve has a= 84 basketball cards
Claire has 7 times less than Steve = 84 /7 = 12=b
STEP 3
if Claire buys 63 more cards
The present value of card Clare now has = 12 +63 = 75 basket ball cards=b
<span>Find the slope of the line going through the points (-9, -6) and (-18, -6).
+ The equation is y = ax+b
+ we have -6= -9a+b or b= 9a- 6
and the second: -6= -18a+b or -6= -18a+ 9a-6 or -9a=0 and a=0, b= 9*0-6= -6
The equation is: y= -6
and the slope is a=0

7 1/2 is already simplified to its lowest terms
Answer:
If solving for x then x = -3/2 +y/2
If solving for y then y = -3-2x
Step-by-step explanation:
For x: Divide both sides by 2
For y: Subtract 2x from both sides of the equation
