It’s (-5,1)
You start at (-3,1) then it tells you to go two left, which is the negative way, and it ends up being (-5,1).
To solve this problem, we can set two equations.
Let x be the cost of coffee and y be the cost of latte.
Two coffees and one latte: 2x + y = 10.50
y=10.50 - 2x ...(1)
Three coffees and two lattes: 3x + 2y = 17.00...(2)
Put (1) into (2), we have:
3x + 2(10.50-2x) = 17.00
3x + 2(10.50) - 2(2x) = 17.00
3x + 21 - 4x = 17
Put the unknown to one side:
3x -4x = 17 - 21
-x = -4
When there are negative numbers on both sides, we can take the negative signs away:
x= 4
Therefore, cost of one coffee is A. $4.00.
Hope ot helps!
Answer:
y = (7/4)(x -4) +12
Step-by-step explanation:
The rate of growth is ...
(19 in -12 in)/(8 wk -4 wk) = 7/4 in/wk
Using this slope in a point-slope form of the equation for a line, we get ...
y = m(x -h) +k . . . . . line with slope m through point (h, k)
y = (7/4)(x -4) +12 . . . . . line with slope 7/4 through the point (4 wk, 12 in)
Answer:
If we are given diameter and we need to find radius then,
Radius(r) = Diameter(d) ÷ 2
⇒ r = d÷2
So here d = 41
So r = d÷2
⇒ r = 41 ÷ 2
⇒ r = 20.5
Answer:
4
Step-by-step explanation:
(-3) * (8/-6)
3 * 8/6
3 * (2 * 4)/6
3 * (2 * 4)/(2 * 3)
3 * (4/3)
