Answer:
x = -19/3 y = 10 write as an ordered pair (-19/3, -10)
Step-by-step explanation:
Step 1: 'Elimination' is done through adding or subtracting. You want to add the two equations together to get rid of one of the variables.
Since the x values have coefficients with opposite signs (-9 and 9), add the two functions together. The result is...
-2y = 20 { -9x + 9x = 0, so x is gone, 4y + (-6y) = -2y, 17 + 3 = 20 }
Step 2: Now solve for the remaining variable, in this case, 'y'
-2y = 20 (divide both sides by -2 to isolate the variable)
y = -10
Step 3: Plug the value for 'y' into one of the original equations to find 'x'
-9x + 4(-10) = 17 ('y' becomes -10)
-9x - 40 = 17 { 4(-10) = -40 } (now add 40 to both sides)
-9x = 57 (divide both sides by -9 to isolate 'x' )
x = -57/9 (now reduce, both are multiples of 3, so divide 3 out)
x = -19/3 ( -57/3 = -19, 9/3 = 3 )
Answer:
lol I'm a senior, you'll have to do the foil method for the rest of high school and college
Answer:
$648.5
Step-by-step explanation:
Given data
Principal= $6,500
Rate= 2.5%
Time= 5 years
The compound interest formula is given as
A= P(1+r)^t
substitute
A= 6500(1+0.025)^5
A= 6500(1.025)^5
A=6500*1.131
A=$7351.5
After 5 years the money in the account will be $7351.5
Now to buy a car of $8,000
The added amount will be
=$8,000-$7351.5
=$648.5
Z=-4. z+6/3=2(z/4); cancel out the 2 on the right side[2/1*z/4---2z/4---z/2]. z+6/3=z/2; cancel out the denominator of 2 on the right side[z/2*2=z \\\ 2(z+6/3)=2z+12/3=2z+4]~~I know its alot, huh? Sry...~~ z=2z+4; subtract both sides by 2z[-z=4; divide by -1; z=-4] I hope that helped.
Hello there!

___________________________________________________
Step-by-step explanation:
First you had to subtract by 6 from both sides of equation.
Simplify.
Then you divide by e³ from both sides of equation.
Simplify it should be the correct answer.
