Solve the equation <br>y=2x-4, 3x+y=11

Ostrovityanka [42]

Answer:

(3, 2)

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

3x + y = 11 → (2)

Substitute y = 2x - 4 into (2)

3x + 2x - 4 = 11

5x - 4 = 11 ( add 4 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Substitute x = 3 into (1) for corresponding value of y

y = (2 × 3) - 4 = 6 - 4 = 2

Solution is (3, 2)

write the equation in standard form of the function with x intercepts at (4,0) and (-2,0) that has been reflected across the x a

Anastaziya [24]

answer

$-3x^{2} +6x + 24$

explanation

since there are 2 x-intercepts, the lowest degree the function could possibly have is 2, so this could be the graph of a parabola

since our zeros are at x = 4 and x = -2, our factors are (x - 4) and (x + 2)

our equation so far is

(x - 4)(x + 2)

= $x^2 -4x + 2x - 8$

= $x^{2} -2x - 8$

since the function is reflected across the x-axis, multiply the equation by -1

$-(x^{2} -2x - 8)$

= $-x^{2} +2x + 8$

since the function has a vertical stretch of 3, multiply the equation by 3

$3(-x^{2} +2x + 8)$

= $-3x^{2} +6x + 24$
