PLEASE HELPP MEE!!!! MATH!!! PLEASEEE HELP ME!!!!!

IRISSAK [1]

Answer:

The solution is (3,2)

Step-by-step explanation:

x - y = 1 →equation 1

-x + 3y = 3 →equation 2

by elimination method,

x - y = 1

-x + 3y = 3

-----------------

0 + 2y = 4

2y = 4

y = 4/2

y = 2

substitute y=2 in equation 1

x - y = 1

x - 2 = 1

x = 1 + 2

x = 3

∴(3,2) is the solution

What is the solution to the inequity 7x-5

Lemur [1.5K]

The answer would be -35. I think so because you multiply -5 by 7. You also multiply 7x by 7 too right?

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-5, 6) → x₁ = -5, y₁ = 6

Point (3, 2) → x₂ = 3, y₂ = 2

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formulas]: $\displaystyle d = \sqrt{(3+5)^2+(2-6)^2}$
[Distance] [√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(8)^2+(-4)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{64+16}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{80}$
[Distance] [√Radical] Simplify: $\displaystyle d = 4\sqrt{5}$
