Answer:
(3,1) and (0,2)
Step-by-step explanation:
Answer: 23 minutes
Step-by-step explanation:
4x + 8 = 100
100 is 8 more than 4 times of minutes than last week.
X = minuted she studied last week.
Find x
4x = 100 - 8
4x = 92
x = 92/4
x = 23 minutes
(-6,0)
Intersecting at x-axis means that the point at which it will intersect will have a x coordinate but no y coordinate.
So,In the equation,y=-3x-18
put y=0
-3x-18=0
or,3x=-18
or,x=-6
So,the point of intersection is (-6,0)
Answer:
a). Nadia made a total of $825 last week in commission sales
b). The total amount Nadia in commission in 2011=$42,900
Step-by-step explanation:
Step 1
Express the amount in commission she earns from her sales as follows;
C=S×r
where;
C=commission earned
S=total value of stock sales
r=commission rate
In our case;
C=unknown
S=$7,500
r=11%=11/100=0.11
replacing;
C=11% of 7,500
C=(11/100)×7,500
C=0.11×7,500=825
Nadia made a total of $825 last week in commission sales
b). To express the total amount she made in 2011, we derive the formula below;
Total amount (2011)=Average weekly commission×number of weeks in 2011
where;
Average weekly commission=$825
number of weeks in 2011=52
replacing;
Total amount (2011)=(825×52)=42,900
The total amount Nadia in commission in 2011=$42,900
Answer:
Step-by-step explanation:
Hello,
let's find a and b reals so that
we identify the terms in
9 = 3a
we identify the terms in x
-18 = 3b + a
we identify the constant terms
-7 = b
so ti goes with a = 9/3 = 3, b = -7
so we can write
so
hope this helps
