Ok so remember
order of simplification
PEMDAS
parenthaseese
exponents
multiplicaton or division whichever comes first
addition or subtraction whichever comes first
ok so remmeber work from the left to right parenthasees first and work from inside to outer parenthasees
so first one
innermost parenthasees first so
first step is 2-4
subtract 4 from 2
second one
if xy=0 then assume x and y=0 so
(a+2)(b-9)=0
a+2=0
a=-2
b-9=0
b=9
so answe ris a=-2
b=9
third questions
innermost parenthaees first
subtract 4 from 2
ok
1. subtrac 4 from 2
2. a=-2, b=9
3. subtract 4 from 2
Answer:
- Angle E corresponds to angle L
- The two triangles are similar
Step-by-step explanation:
<u>Angle E corresponds to angle L</u> because <u>the two triangles are similar</u> (and we know this becuase corresponding sides are proportional.
Since Pauline spent $7.50 for 3 days, all you have to do is multiply 7.50 by 3 to get 22.50. Your answer would be D.<span>(7.50) × (3) = 22.50; She spent $22.50.</span>

Answer:
maybe 21?
Step-by-step explanation:
Answer:
-5/2
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (-2 - 8)/(6 - 2) = -10/4 = -5/2
so y = mx + b
y = -5/2x + b
Using (2,8)
8 = -5/2(2) + b
8 = -5 + b
b = 13
then y = -5/2x + 13
