Answer:
(x, y) = (18/5, 16/5)
OR
(x, y) = (3.6, 3.2)
Use the distance formula to find the value of the side lengths.
d=√((x1-x2)²+(y1-y2)²
d of side AC is 6
d of side CB is 10
Angela's use of the Pythagorean Theorem of 10²+6²+c² is incorrect; she put the right values in the wrong spots, the formula needed is:
6²+10²=c²
Option C- Angelica's side lengths were too long.
Answer:
plane = 250mi/hr
wind = 5mi/minute
Step-by-step explanation:
speed = distance/time
plane = 1000miles/4hour
wind = 1000miles/200minutes
Answer: y = 2x+11
----------------------------------------------
Explanation:
The given line y = 2x-4 has a slope of m = 2 as it is in the form y = mx+b
m = slope
b = y intercept
Anything parallel to the given line will also have a slope of m = 2 as well. Parallel lines have equal slopes.
The given point is (x,y) = (-3,5) so x = -3 and y = 5 pair up
We will plug m = 2, x = -3 and y = 5 into the equation below and solve for b
y = m*x+b
5 = 2*(-3)+b
5 = -6+b
5+6 = -6+b+6 ... add 6 to both sides
11 = b
b = 11
Because m = 2 and b = 11, this means we have y = mx+b update to y = 2x+11 which is the final answer
Let x represent the amount of savings
of savings minus tv equals zero
- 200 = 0
= 200
3x = 4(200)
x = 266.67
Answer: $266.67
