a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to  45/99  which is  <em>5/11</em> .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is  4/10

The 0.5555555555.../10 part is  5/90 .

(4/10) + (5/90) = <em>41/90 </em>

c). 0.45 means 45/100 .  That's <em> 9/20</em> .

I don't think you're supposed to be posting unit test questions on Brainly.

Answer:

4u= - 4i - 24j

u +w = -9i - 3j

Step-by-step explanation:

The question is on operation of vectors

Given u= -i -6j  and w= -8i+3j

Then 4u = 4{ -i-6j}

4u= - 4i - 24j

u+w= -i -6j + -8i+3j......................collect like terms

= -i -8i + -6j +3j

= -9i + -3j

= -9i - 3j

!! Need help with the problem in the photo. !!
lianna [129]

Answer:

B 3x-2y=10

Step-by-step explanation:

This is correct because when solved it has the same slope as line <em>k.</em>

The slope of <em>k</em> is 3/2.

3x-2y=10

first subtract 3x from both sides

-2y=-3x+10

next divide both sides by -2

y=3/2x-5

this shows that the slope 3/2 is the same as line <em>k</em>
