Answer:

y = 1/4x + 0 or just y = 1/4x

Step-by-step explanation:

First I need the slope so I look at the dots and see how much boxes it goes up and then to the side. So it’s up 2 to the side 8. The slope would be 2/8 but you can simply it by 2 and you get 1/4. And the y intercept is given its zero.

How do I work this out I need full answer im lost

taurus [48]

Answer:

7x = 35cm ; 2x = 10cm

Step-by-step explanation:

7x and 2x are the lengths

7x+2x=45

Then you take 7 + 2 = 9

so is gonna be 9x = 45

then you divide both side with 9

so is gonna be x = 5

Then you take 5 multiply 7 : 2

so 7 x 5 = 35cm

2 x 5 = 10cm

For what values of K does x2+kx+9=0

Airida [17]

Answer:

$k = 6$

Step-by-step explanation:

$x {}^{2} + kx + 9 = 0$

here,

a = 1,

b = k

c = 9

now,

$D = b {}^{2} - 4ac$

$k {}^{2} - 4(1)(9) = 0 \\ k {}^{2} - 36 = 0 \\ k {}^{2} = 36 \\ k = 6$
