<span>RS= 8y + 4, ST = 4y + 8, and RT = 36
RS + ST = RT
</span>8y + 4 + 4y + 8 = 36
12y + 12 = 36
12y = 24
y = 2
answer
y = 2 (first choice)
Answer:
c
Step-by-step explanation:
Answer:
y = -2x + 1.
Step-by-step explanation:
2y = x - 1
y = 1/2y - 1/2
If line X is perpendicular to line Y (the line where y = 1/2y - 1/2), the slope will be the negative reciprocal of line Y. That means that there will be a negative sign instead of positive, and the 1/2 will be flipped to become 2/1, which is 2.
So, the slope will be -2.
We now have y = -2x + c.
To find c, simply put in -1 for x and 3 for y.
3 = -2 * -1 + c
c + 2 * 1 = 3
c + 2 = 3
c = 1
So, the equation of the line is y = -2x + 1.
Hope this helps!
Answer:
A , B, and D
Step-by-step explanation:
you find the unit prices by dividing the cost per pound
a bc it sells them at $1.52 per pound
b bc it sells them at $1.49 per pound
NOT c because it sells them at $3.14 per pound
D because it sells them at $1.88 per pound
(2c) / (3b)
(2*6) / (3*2) =
12/6 =
2 <===
