Answer:
y = 1/4 x -3
Step-by-step explanation:
y = -4x + 3;
the slope of this equation is -4
we want the slope perpendicular to this
take the negative reciprocal
- (-1/4) = 1/4
so the slope of our line will be 1/4
we have the slope and a point so we can use point slope form
y-y1 = m (x-x1)
y--2 = 1/4(x-4)
y+2 = 1/4 (x-4)
we need to change it to slope intercept form (y=mx+b)
distribute
y+2 = 1/4 x -1/4*4
y+2 = 1/4x -1
subtract 2 from each side
y +2-2 = 1/4 x -1-2
y = 1/4 x -3
the slope is 1/4 and the y intercept is -3
Answer:
1200 packets of tea
Step-by-step explanation:
Its because theres 1000 grams in 1kg so it would be 600000 grams and you would divided 600000 over 500 and get 1200
Can you mark brainlyist?
Step-by-step explanation:
to solve you just add the length of each line segment. In this problem 1.7+3.2=4.9
7) y = 4x
8) y = 7x/8
9) y = 25x/3
I think this are the answers.
Answer:
SA = 2520 ft^2
Step-by-step explanation:
a = 21ft
b = 29ft
c = 20ft
h = 30ft
SA = 2
+ (a+b+c)h
= s(s﹣a)(s﹣b)(s﹣c)
s = 
SA= ah + bh + ch + 
SA= (21 * 30) + (29 * 30) + (20 * 30) +
SA = 2520 ft^2
