Step 1: Define Systems
5x + 2y = 9
y = -x - 3
Step 2: Solve for x
Substitution
Substitute in y: 5x + 2(-x - 3) = 9[Distributive Property] Distribute 2: 5x - 2x - 6 = 9Combine like terms: 3x - 6 = 9[Addition Property of Equality] Add 6 on both sides: 3x = 15[Division Property of Equality] Divide 3 on both sides: x = 5Step 3: Solve for y
Define original equation: y = -x - 3Substitute in x: y = -5 - 3Subtract: y = -8$150 per hour is how much per min

What is the best approximation of the solution to the system to
the nearest integer values?
o
(3, 4)
o
(2, 3)
O (1, 3)
o (3, 2)
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)

Please help with my work!
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

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
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
x=2

f(10) means replace all x's with 10. f(10) = 3(10) - 2 -> 30-2 = 28
Find the sine, cosine, and tangent of angle A. (fraction as in simplest form please.)
Answer:
SinA=3/5
CosA=4/5
TanA=3/4
Step-by-step explanation:
first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2
20^2-16^2=144 the square root of 144 is 12 so side length bc=12
so sin is opposite/hypotenuse
the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5
cos is adjacent/hypotenuse
the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5
tan is the opposite/adjacent
the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

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?
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
