Y=x^(2) -2x - 3 and y = x - 3

Mathematics
1 answer:
Oliga [24]2 years ago
5 0

Answer:

(0, -3) and (3, 0)

Explanation:

1st equation: y = x² -2x - 3

2nd equation : y = x - 3

Using substitution method:

x² -2x - 3 = x - 3            <em>exchange sides</em>

x² - 2x - x - 3 + 3 = 0    <em>simplify</em>

x² - 3x = 0   <em>                 take common factor</em>

x(x - 3) = 0                    <em>simplify</em>

x = 0, 3

Solve for y:

when x is 0, y = x - 3 = 0 - 3 = -3

when x is 3, y = x - 3 = 3 - 3 = 0

Point A has the coordinates (3 - 7). Find the coordinates of A', the image of A after it has been translated left 4 units and do
TiliK225 [7]

Answer:  (-1,-9)

Step-by-step explanation:

If a point is translate up or down  it means your using the y coordinate an if a point is translated left or right your using the x coordinate.

So the x coordinate is  3  and is translated  to the left by 4 units so is moving back by 4 .

3-4 = -1  

The y coordinate is -7  and is also translated down by 2 units so it is also decreasing.

-7 -2 = -9  

so the image is  (-1,-9)

vlabodo [156]

Answer:

a, d, e

Step-by-step explanation:

#1  Multiply the two polynomials.

(2x+3)(5x^2+3x+2)=(2x)(5x^2)+(2x)(3x)+(2x)(2)+(3)(5x^2)+(3)(3x)+(3)(2)\\=10x^3+6x^2+4x+15x^2+9x+6\\=10x^3+21x^2+13x+6

#2

(3y+4)(2y^2+5y-3)=(3y)(2y^2)+(3y)(5y)-(3y)(3)+(4)(2y^2)+(4)(5y)-(4)(3)\\=6y^3+15y^2-9y+8y^2+20y-12\\=6y^3+23y^2+11y-12
