Answer:
The number is 31
Step-by-step explanation:
Let the number be x
Subtract 12 from the number = x - 12
Then multiply the difference by -7 = (-7)*(x - 12)
(-7)(x - 12) = -133
-7x - 12*(-7) = -133
-7x + 84 = - 133
-7x = -133 - 84
-7x = -217
x = -217/-7
x = 31

When a principal amount, P, is invested at an annual interest rate,r, and compounded n times per
year, the amount accumulated in the account after t years can be found with the equation:
A = P(1+ :)"
Javier invested $2,350 in a savings account for 5 years with a rate of 1.75% compounded every six
months. In this situation, what is n?
Answers
Answer:
2
Step-by-step explanation:
A = P( 1+r/n) ^ (nt)
P is the amount invested
r is the rate
n is the number of times per year the interest is compounded
t is the number of years
every 6 months is twice a year
so n is 2

Solution:
Answers
Answer:
y=2/3
Step-by-step explanation:
Answer:
(-2,3) x= -2 y=3
Step-by-step explanation:
The first thing you should do is convert both into standard y=mx+b form
For the first equation you subtract 5y and add 11 to both sides to get
13x+11= -5y
you divide by negative 5 to get
-13x/5-11/5=y
For the second equation we subtract 11y and 7 from both sides to get
13x-7= -11y
divide both sides by -11 to get
-13x/11 + 7/11
We then set both equations equal to each other and solve for x
-13x/5-11/5= -13x/11 + 7/11
Add 11/5 to both sides to get
-13x/5 = -13x/11 + 156/55
Add 13x/11 to both sides to get
-78/55x=156/55
Divide and solve for x to get -2
Then plug x = -2 into the original equations to find y
13*-2 + 5y = -11
-26 + 5y = -11
Add 26 to both sides
5y= 15
y =3

x square + 12x =1
Answers
Answer:
x = - 6 ± [tex]\sqrt{37}[/tex]
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± [tex]\sqrt{37}[/tex] ( subtract 6 from both sides )
x = - 6 ± [tex]\sqrt{37}[/tex] ← exact solutions

Step-by-step explanation:
36-14 = 22
22/2= 11
11+14 = 25
Answer:
11 and 25
Step-by-step explanation:
The two numbers we'll call x and y. Let's set up equations to model the situation:
x+y=38
x-y=14
Solving the second one for x,
x=y+14
Plug this into the first equation for x and get:
(y+14)+y=36
2y+14=36
2y=36-14
2y=22
y=11
x-y=14
x-11=14
x=14+11
x=25

Multiply both sides by 5:
2(5x-3)+3=20x-1
Distribute:

Subtract 10x from both sides:
