Answer:
y = -x - 3
x = -y - 3
Step-by-step explanation:
If solving for y,
-7y = 7x + 21
-y = -x + 3 (dividing everything by 7)
y = -x - 3
If solving for x,
-7y = 7x + 21
-y = -x + 3
x = -y - 3

You invest $125,000 in an account that earns 4.75% annual
interest, compounded continuously.
a. What is the value of the account after 15 years?
Step-by-step explanation:
step 1. let's call the amount of money A, the initial amount A¡, the rate r, and the time t.
step 2. A = A¡e^(rt) (continuously compounding equation)
step 3. A = 125000e^((.0475)(15))
step 4. A = $254,885.32
The value of the account after 15 years will be $254885.
In theory, continuously compounded interest means that an account balance is constantly earning interest and reinvesting that interest so that it, too, earns interest.p explanation.
In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor.
Given that you invest $125,000 in an account that earns 4.75% annually for 15 years of the time.
The compound interest will be calculated as:-
[tex]P(t) = P_o\times e^{rt}\\P(t) = 1250000\times e^{0.0475\times 15}[/tex]
P(t) = $254885
Hence, the value of the account after 15 years will be $254885.

algebra 1 evaluating algebraic expressions?
3x=10
Answer:
x=3.33333333
Step-by-step explanation:
Answer:
x = 10/3
Step-by-step explanation:
Divide the coefficient of x (3) on both sides, 3x/3 = 10/3 - then divide the three and the three to get 1 (which stays as x) and then divide ten by three or just leave it as an improper fraction (this all depends on what your teacher's preference) and then you will get the final answer of x = 10/3 or x = 3.3.

which is an equation of the line
a. y = x - 1
b. y= x + 1
c. y= -x -1
d. y= -x + 1
Answer:
the form is y = mx + b an db is the y intercept. the y intercept is 1 so it is not a or c. The slope is positive, so it is b!!!

A bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.
Which option lists a true statement about how a distance-time graph would represent this motion?
A) The slope of the graph would be negative and constant for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.
B) The slope of the graph would be positive and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents velocity.
C) The slope of the graph would be positive and increasing for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.
D) The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time.
Answer:
D
Step-by-step explanation:
The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time. Therefore, option D is the correct answer.
What is a constant velocity?Velocity gives us information about the rate of change of your position, meaning how fast your position is changing per unit time.
Given that, a bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.
Here, rate of change is 12/6 = 2 s
Therefore, option D is the correct answer.

1. y = -6x – 7
y = -7x
2. -y=x
3x+5y=20
Answer:
For no. 1:
One of the equations say that y=-7x
So plug in -7x to the other equation as y so you equation would be
-7x= -6x-7
And then, just solve for the variable:
*add -6x to both sides*:
-x= -7
*multiply both by negative one to get a positive variable*
FOR NUMBER 1, THE ANSWER IS:
x=7
Y=-7
For no. 2:
-y=x and your other equation is 3x+5y=20
Plug in x as -y:
-3y+5y=20
*simplify*
2y=20
*divide by 2 on each side to get 1 variable alone*
Y=10
FOR NUMBER 2, THE ANSWER IS:
x=-y
Y=10

Marco brought $25 to a facility that has indoor batting cages. He can buy 1 token for $1.25, which will give him 15 pitches. He needs to have at least $5 leftover to buy lunch. How many tokens, t, can Marco buy and still have enough money for lunch?
First what I did was take out the 5 dollars. So I did 25 minus 5.
25 - 5 = 20
Next, I divide the left over 20 dollars by 1.25 to see how many tokens Marco could buy.
20 / 1.25 = 16
Which i came up with 16. So Marco can buy 16 tokens and still have enough money to use to buy lunch.

67°

Answer:
m∠2 = 67°Step-by-step explanation:
m║n ⇒ (9x + 2)° = 74° {Corresponding Angles}
(9x)° = 72°
x = 8
Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)
(5×8 - 1)° + 74° + m∠2 = 180°
39° + 74° + m∠2 = 180°
113° + m∠2 = 180°
m∠2 = 180° - 113°
m∠2 = 67°
