For questions 1 and 2, use factoring to find the x-intercepts of these quadratic equations.

1 answer:

6 0

1.x^2 +6x - 4 = 6x
X^2 + 6x -4 - 6x = 0
X^2 - 4 = 0
By difference of two squares :
X^2 - 4 = 0 can be written as (x-2) (x+2) = 0
(X-2)=0 therefore x= 2

(X+2)=0 therefore x= -2

2. X^2 - 8x = -6x
X^2 -8x + 6x = 0
X^2 - 2x = 0
X(X-2) = 0
X= 0, X= 2

On the blueprint of a house, 40 millimeters represents 6 meters. The length of the living room is 50 millimeters on the blueprin

Novay_Z [31]

Answer:

Convert the meters to millimeters

1m = 1000mm

6m = 6000mm

40mm represents 6000mm

Find the scale factor

6000/40 = 150

This means 40 * 150 = 6000

Yup find what 50mm represents:

50 * 150 = 7500

7500mm

7.5m

MATH.... TRIANGLE JKL HAS VERTICES...

7nadin3 [17]

<h3>Answer: Choice (d)</h3>

Explanation:

To reflect over the y axis, we apply this rule

$(x,y) \to (-x,y)$

which says to flip the sign of the x term but keep the y coordinate the same.

So that means something like J(-2,5) becomes J ' (2, 5). The other points are handled in the same fashion and that leads us to choice (d). Points on the y axis will stay where they are.
