can you PLEASE show in words and explain your answer i need help!
Answer:
90
Step-by-step explanation:
we have:
9*(7-4)^2+9
we subtract 7 and 4: 7-4
we have:
9*(3)^2+9
we know: 3^2=3*3=9
so we have:
9*9 +9
we multiply 9 by 9: 9*9 = 81, so we have:
81+9
90
Answer:
Step-by-step explanation:
To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract numbers from left to right. Please Excuse My Dear Aunt Sally!
First, parenthesis.
(7-4)=3
9*3²+9
Next, exponent.
3²=3*3=9
9*9+9
Then, multiply numbers from left to right.
9*9=81
Add numbers from left to right.
81+9=90
Therefore, the correct answer is 90.
B. y = 6x + 1
C. y = -6x + 1
D. y = -6x – 1
The expression into an equivalent form would be; A. y = 6x – 1
Those expressions that might look different but their simplified forms are the same expressions are called equivalentexpressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need to the expression into an equivalent form.
This expression could also be given as
6x – y = 1
Now, we know that:
6x – y = 1
6x = y + 1
y = 6x - 1
Hence, the required expression into an equivalent form 6x – y = 1 would be; y = 6x - 1

Answer:
A. y = 6x – 1
Step-by-step explanation:
Answer:
amount invested in mutual fund B; $4,800
amount invested in mutual fund A; $8,200
Step-by-step explanation:
Let the amount invested in mutual fund B be x. Then the amount invested in fund A would be;
(13000-x)
The loss emanating from fund B would be;
3.5% of x
=(3.5/100)*x
=0.035x
The profit resulting from investment in fund A would be;
6% of (13000-x)
= (6/100)*(13000-x)
=0.06(13000-x)
=780-0.06x
The total profit earned from funds A and B in terms of x will be;
780 - 0.06x + (-0.035x)
=780 - 0.095x
The total profit earned was 324, thus;
780 - 0.095x = 324
solving for x;
780 - 324 = 0.095x
456 = 0.095x
x = 4800
Then the amount invested in fund A would be;
13000 - 4800 = 8200
Answer: 108°
Step-by-step explanation:
Since, by the given table,
The percentage of the students who choose orange juice = 30 %
Thus the fraction that choose orange juice =
Hence, out of total students 3/10 part of students choose orange juice.
Now for finding the central angle,
⇒
⇒
⇒
That is, the central angle of the students who choose orange juice is 108°
Hence, Fourth option is correct.
