(1) x = (6.6 +5)/2 = 5.8
(2) m = (4/3)*(13 -4) = 12
(3) p = (2/5)*(13 +3) = 6.4
(4) m = (11.5 -4.5)/3.5 = 2
(5) x = (21.5 -3.5)/9 = 2
Answer:
{ 3 }
Step-by-step explanation:
-30+9x=-0.5 |x-1| -2
from the graph, we can see that both curves intersect at (3,-3)⇒x=3
put x=3 in LHS&RHS
⇒LHS=-30+9(3)=-3
RHS=-0.5 |3-1|-2=
-1/2×2-2=-1-2=-3
so the answer will be 3..
hope it helps..
have a great day!!
Answer:
an Injective function is a function that maps distinct elements of its domain to distinct elements of its codomain. In other words, every element of the function's codomain is the image of at most one element of its domain.
Step-by-step explanation:
Irrational, because if you simplify the root V72=6V2
Answer:
<u><em>y=7 </em></u><u>number of hours at grocery store</u>
<u><em>x=18 </em></u><u>number of hours at baby- sitting</u>
Step-by-step explanation:
According to the information provided.
x is number of hours at baby- sitting
y is number of hours at grocery store
total number of hours worked
<em>1) </em><em>x+y =25</em>
total earn in a week
<em>2) </em><em>x*$6 + y* $9 = $171</em>
<em />
<em>from equation 1</em>
x+y=25
x= 25-y
<em>we place the above derived equation in equation 2 </em>
x*$6 + y* $9 = $171
(25-y)*$6 + y* $9 = $171
(25*6) -6y +9y =171
150+3y=171
3y=171-150
3y=21
<u><em>y=7 </em></u><u>number of hours at grocery store</u>
x= 25-y
x= 25-7
<u><em>x=18 </em></u><u>number of hours at baby- sitting</u>
