Hello!

5a - 9a - (-2a) =

= 5a - 9a + 2a =

= -4a + 2a =

= -2a

Good luck! :)

25% of 60 to 40% of 30<br> >, < or =

Travka [436]

You can reduce the percentages to fractions:

$25\% = \dfrac{25}{100} = \dfrac{1}{4}$

$40\% = \dfrac{40}{100} = \dfrac{2}{5}$

So, we have

$25\% \text{ of } 60 = \dfrac{1}{4}\cdot 60 = 15$

$40\% \text{ of } 30 = \dfrac{2}{5}\cdot 30 = 12$

Write the equation that describes the line in slope-intercept form: slope= 4, point (3,-2) is on the line

docker41 [41]

Slope intercept form is y=mx+b
m=slope
b=y intercept

slope is 4
y=4x+b
subsitute if iin (x,y) form
so x=3 and y=-2 is one solution
subsitute
-2=4 times 3+b
-2=12+b
subtract 12 from both sids
-14=b

the equation is y=4x-14

2 circles labeled Set A and Set B overlap. Set A contains 1, set B contains 3, and the overlap of the 2 circles contains 2. The

The region(s) represent the intersection of Set A and Set B (A∩B) is region II

<h3>How to determine which region(s) represent the intersection of Set A and Set B (A∩B)?</h3>

The complete question is added as an attachment

The universal set is given as:

Set U

While the subsets are:

Set A
Set B

The intersection of set A and set B is the region that is common in set A and set B

From the attached figure, we have the region that is common in set A and set B to be region II

This means that

The intersection of set A and set B is the region II

Hence, the region(s) represent the intersection of Set A and Set B (A∩B) is region II
