What’s the solution of Y=1/2x+7 y=-3/4x+2

(- 4, 5 )

Step-by-step explanation:

Given the 2 equations

y = x + 7 → (1)

y = - x + 2 → (2)

Since both equations express y in terms of x, equate the right sides

x + 7 = - x + 2

Multiply through by 4 to clear the fractions

2x + 28 = - 3x + 8 ( add 3x to both sides )

5x + 28 = 8 ( subtract 28 from both sides )

5x = - 20 ( divide both sides by 5 )

x = - 4

Substitute x = - 4 into either of the equations and solve for y

Substituting x = - 4 into (1)

y = (- 4) + 7 = - 2 + 7 = 5

Solution is (- 4, 5 )

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
