Answer:
x,y =3,-4
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 10
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-10) = 17
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-10
// Use the x value to solve for y
y = 2(3)-10 = -4

Jake lives 2⅓mile from school. He decides to walk to the shop on his way home. The shop is 1⅜mile from school. A) What is the shortest possible distance from the shop to his home? B) What is the largest possible distance from the shop to his home?
Answers
Answer:
Shortest distance = 23/24
Farthest distance = 3 17/24 miles
Step-by-step explanation:
Distance of home from school = 2 1/3 miles
Distance of shop from school = 1 3/8 miles
Shortest distance possible :
(2 1/3 - 1 3/8) miles
(7/3 - 11/8) miles
L. C. M = 24
(56 - 33) / 24
23 / 24 miles
The farthest distance :
(2 1/3 + 1 3/8) miles
(7/3 + 11/8) miles
L. C. M = 24
(56 + 33) / 24
89 / 24
= 3 17/24 miles

A. 55°
B. 40°
C. 35°
D. 25°
thanks ;)
Answers
Angle 3 and 6 both equal 90 degrees. angle 1 is collinear with 6 and 5. Those three angles (1,6, and 5) add up to 180 degrees. If you subtract your angle 6(90) from 180 , you get 90 , then u subtract ur angle one(55) from 90 and get 35 degrees. I hope this makes sense, it’s harder to explain online

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answers
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5

Answers
Answer: (2,3)
====================================================
Explanation:
The intersection point of the two lines is where the solution point is located.
The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.
At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.
So that's how we get to (2,3)
