Y=3/4x - 6 find the x-intercept of the line

Ede4ka [16]

Answer:

The x intercept is (8,0)

Step-by-step explanation:

To find the x intercept set y = 0 and solve for x

Y=3/4x - 6

0 =3/4x - 6

6 = 3/4x

4/3 *6 = 4/3*3/4x

8 =x

The x intercept is (8,0)

The equation x^2+ (k - 3)x + (3 - 2k) = 0, where k is a constant, has two distinct real roots.

Lisa [10]

Step-by-step explanation:

For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,

b^2 - 4ac must be positive.

b^2 - 4ac > 0

(k - 3)^2 - 4(3 - 2k) > 0

k^2 - 6k + 9 - 12 + 8k > 0

k^2 + 2k - 3 > 0

Bethany, Lauren, Amanda, and David all meet at a family reunion. They are comparing their ages. They have found that Lauren is 1

tekilochka [14]

Lauren =l
David=d
Bethany's =x
Amanda =y
l=x+13
d=y+11
lx=2y
(x+13)x=2y
 $2y=x^2+13x$
$y= \frac{1}{2}(x^2+13x)$
or
$y= \frac{x^2}{2}+ \frac{13}{2}x$
(x-20)(l-20)=d
(x-20)(x+13-20)=y+11 
 $y+11=(x-20)(x-7)$
$y+11=x^2-27x+140$
$y=x^2-27x+129$
so I believe its b
Hope this helps :)
