If f(a)=(a•a•a)-(a•a) + a-1 what is the value of f(-3)?
Answer:
-40
Step-by-step explanation:
f(a) = a³ - a² + a - 1
f(-3) = (-3)³ - (-3)² + (-3) - 1
f(-3) = (-27) - (9) + (-3) -1
f(-3) = -27 - 9 -3 - 1
f(-3) = -40

Step-by-step explanation:
Consider the system of equations, y = f(x) and y= g(x), where
f(x) = 11x-7 and g(x) = 3x + 17.
Which method would you use to solve this system of equations? Explain
your reasoning and provide the solution to the system.
Answer:
(x, y) = (3, 26)
Step-by-step explanation:
I like to solve systems of equations like this by graphing. A graphing calculator easily shows the solution for both x and y.
(x, y) = (3, 26)
__
As an alternative, here, the equations can be subtracted.
y = f(x)
y = g(x)
0 = f(x) - g(x) . . . . subtract the second equation from the first
0 = 11x -7 -(3x +17)
0 = 8x -24 . . . . simplify
0 = x -3 . . . . . . .divide by 8
3 = x
Now, we can substitute into either equation:
y = g(x) = 3(3) +17 = 26
The solution is (x, y) = (3, 26).
Which table has a constant of proportionality between Y and X of 3/4
Answer:

Step-by-step explanation:
The constant of proportionality is the ratio of y to x.
A: 6/8 = 3/4 . . . . this is the table you want
B: 1/4 = 1/4 . . . . . constant is not 3/4
C: values are not proportional

Step-by-step explanation:
Santiago has $6000 spread across his 3 accounts. He has a checking account which pays 2% interest, a savings account that pays 5% interest, and a money market account which pays 7% interest. At the end of 1 year, he earned a total of $355 in interest. If he put $2300 less in his savings accout than his money market account. Find how much money Santiago put into each account
Answer:
Santiago put $700 into a checking account, $1,500 into a savings account and $3,800 into a money market account.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y+z=6000 (1)
0.02x+0.05y+0.07z=355 (2)
y=z-2300 (3)
First, you have to replace (3) in (1) and (2):
x+z-2300+z=6000
x+2z=8300 (4)
0.02x+0.05(z-2300)+0.07z=355
0.02x+0.05z-115+0.07z=355
0.02x+0.12z=470 (5)
Now, you have 2 equations:
x+2z=8300 (4)
0.02x+0.12z=470 (5)
Then, you can solve for x in (4):
x=8300-2z (6)
After this, you have to replace (6) in (5):
0.02(8300-2z)+0.12z=470
166-0.04z+0.12z=470
0.08z=304
z=3800
Now, you can replace z in (6) to find x:
x=8300-2(3800)
x=700
Finally, you can replace z in (3) to find y:
y=3800-2300
y=1500
According to this, the answer is that Santiago put $700 into a checking account, $1,500 into a savings account and $3,800 into a money market account.

Show all work to multiply (3+sqrt(-16))(6-sqrt(-64))
(I've attached a picture of the equation for reference)
Answer:
-14
cuz sqrt of -16 is -4 and sqrt of -64 is -8 but there is an - sign there so it is positive
then 3+-4 is -1 and 6+8 is 14
lastly multiply and you get negative 14
Review the expressions for j(x) and j(–x)
j(–x) StartFraction 220 Over (negative x) cubed EndFractio"
Which statement describes the symmetry of j(x)?
Which statement describes the symmetry of j(x)?
j(x) is an odd function.
j(x) is an even function.
j(x) is both an even and an odd function.
j(x) is neither an even nor an odd function.
Answer:
a Negative values, like −4ac, do not have a square root.
Step-by-step explanation:
In the case above, the statement that describes the symmetry of j(x) is that j(x) is an odd function.
What is the odd function about?Note that:
j(x) = 220/x³
j(-x) = 220/(-x)³
If x = 1; then:
j(x) = 220/1³
= 220/1
= 220
j(-x) = 220/(-1)³
= 220/-1
= -220
If x = 2; then:
j(2) = 220/2³
= 220/8
j(-2) = 220/(-2)³
= -220/8
Note also that function j would be an even number only when j(-x) = j(x) for all x in the space of j.
But j is odd only when j(-x) = -j(x) for all x in the space of j.
Looking at the values obtained, we see that: j(-x) = -j(x). Therefore, In the case above, the statement that describes the symmetry of j(x) is that j(x) is an odd function.

PLEASE HELP ME QUICK Write a mathematical sentence for the inequality:
Twice the difference of a number and seven is less than or equal to forty.
Complete your work in the space provided. In the form of a paragraph, explain the process necessary to solve the inequality for the unknown values. In your answer, include the inequality sentence, solution and explanation.
2 * n - 7 <= 40
[tex]2 * n - 7 \leq 40\\n-7\leq 20\\n\leq 27[/tex]
To solve this equation, you need to isolate the variable. The equation is "2 * n - 7 <= 40". First, divide both sides by 40 using the division property of equality. This gets "n - 7 <= 20". Then, to further isolate the variable add 7 to both sides using the addition property of equality. This gets the solution which is, "n <= 27"
