Yes that is true if you think of it as a point and the lines extending in both directions.

3.
Zanzabum

Answer:

see below

Step-by-step explanation:

y = 8x − 9

y = 4x − 1

Since both equations are equal to y, we can set them equal to each other

8x-9 = 4x-1

Subtract 4x from each side

8x-4x-9 = 4x-4x-1

4x-9 = -1

Add 9 to each side

4x-9+9 = -1+9

4x = 8

Divide each side by 4

4x/4 = 8/4

x=2

Now find y

y = 4x-1

y = 4(2)-1

y = 8-1

y = 7

(2,7)

The point of intersection when the 2 lines are graphed is (2,7)

Find a quadratic expression with integer coefficients whose roots are <img src="https://tex.z-dn.net/?f=5%2F2%2B%203i" id="TexFo
prohojiy [21]

Answer:

4x² -20x  +61

Step-by-step explanation:

the quadratic equation can be written as (x-root1)(x-root2)

(x-(5/2) -3i) (x-(5/2)+3i), distribute

x² -(5/2)x +3xi -(5/2)x + 25/4 -(15/2)i -3xi +(15/2)i -9i², simplify

x² -(5/2)x -(5/2)x + 25/4  -9i², use the fact that i² =(√-1)² = -1 and substitute i²

x² -(5/2)x -(5/2)x + 25/4 +9, combine like terms and rewrite 9 as 36/4

x² -(10/2)x  +25/4 + 36/4, combine like terms and simplify

x² -5x  +61/4 is the quadratic expression yet it does not have integer coefficients so multiply by 4 to have all coefficients integers

4x² -20x  +61

Find the geometric mean of the pair of numbers. Give your answer in simplest radical form.
NARA [144]

9514 1404 393

Answer:

  10√5

Step-by-step explanation:

The geometric mean of two numbers is the square root of their product.

  m = √(20×25) = √500 = √100 × √5

  m = 10√5

The geometric mean of 20 and 25 is 10√5.
