y = x − 4

Round your answers to the nearest hundredth.

Answer 1

(x1,y1) = (0.82, - 3.18)

(x2,y2) = (-0.82, -4.82)

Answer 2

Explanation:

we are given a system of quadratic and linear equation

we want to figure out x and y

in other words the coordinates where the linear function intercept quadrilateral function

to do so

you can use substitution method

since y equals to both equation so substitute:

move right hand side expression to left hand side and change its sign so there's only 0 left on the left hand side:

simplify addition:

add 2 to both sides:

divide both sides by 3

square root both sides:

rationalise the denominator by multiplying √3/√3:

now let's figure out y

substitute the value of x to the linear equation:

when positive

when negative
