Answer:
y=-4x+3
Step-by-step explanation:
The slopes of 2 parallel lines will always be the same, so we plug in the ordered pair to find the y intercept
<u>Hope this helps :-)</u>
The slope of this triangle is -2/1
Answer:
The cost of 1kg jam is $7 and the cost of 1kg butter is $4
Step-by-step explanation:
Let jam = x
butter = y
3x + 2y = 29 -----(1)
6x + 3y = 54 -----(2)
(1)×2 ->
6x + 4y = 58 -----(3)
(3)-(2) ->
y = 4
suby=4into(2)
6x + 3(4) = 54
6x = 42
x = 7

Answer:
This means that Alex answered 14 questions correctly
Step-by-step explanation:
<u>Step 1: Find an equation</u>
20 * 0.7 = x
<u>Step 2: Multiply</u>
20 * 0.7 = x
14 = x
Answer: This means that Alex answered 14 questions correctly
If it is bisector then it co ordinate points is in mid way(3,-2)
and it is perpendicular so its slope m2=-1/m1
where m1 is slope of another line passes through (4,1) nd (2,-5)
m1=-5-1/2-4=3
m2==-1/3
so equation of line is
y-3= -1/3(x+2)
