How would i solve 4x-3y=8
5x-2y=-11
using the elimination method?
i'm in algebra 1 and we had a sub the day we were doing this and he was terrible explaining the situations on the worksheet. please explain
Answers
Here you can multiply the first equation by 2, and the second equation by -3.
Now you just add the equations by sides and solve for one variable.
Now you solve for the other variable by substituting -7 for x in one of the equations.
You could choose x at the beginning as well. Then you'd have:
So the answer is:
Answer:
x=-7 and y=-12

Answers
x + y = 2 ... y = 2 - x
2x + y = 4
_________________
2x + (2 - x) = 4
2x - x = 4 - 2
x = 2
y = 2 - x = 2 - 2 = 0
(x, y) = (2, 0)
The correct result would be: There is one solution.

Find out the what will their monthly income be .
To proof
Let us assume that the their monthly income be x .
As given
Ronda Rollins gets a Social Security benefit of $350 per month
Her husband receives a benefit equal to 200 percent of Ronda's benefit.
If they take an additional $400 per month from savings .
200% written in the decimal form
Than the equation becomes
x = 350 + 700 + 400
x= $1450
Therefore monthly income be $1450 .
Option (D) is correct .
Hence proved

solve for x
replace x with f inverse
replace y with x
so
first minus 2 both sides
y-2=√(2x-3)
square both sides
y^2-4y+4=2x-3
add 3 to both sides
y^2-4y+7=2x
divide both sides y 2
(y^2-4y+7)/2=x
x turns to f inverse and y turns to x
f(x)⁻¹=
looks like they didn't want to expand the binomial

If we divide the expressions and found in decimals then we found that 1/4 is greater than 1/8.
What is division?
Division is one of the four basic operations of arithmetic, it is the result of the number p/q. P/q can be found by dividing P by q.
How to divide number?
The given numbers are 1/4 and 1/8.
Value of 1/4=0.25
Value of 1/8=0.125
From the values we can conclude that 1/4 is greater than 1/8.
Hence we found that 1/4 is greater than 1/8.

4*8 = denominator for both numbers.
8*1 = numerator for the first number
4*1 = numerator for the second number.
This should give you the fractions with common denominators, 8/32 and 4/32. Then, to compare the fractions, just see which numerator is larger. In this case, 8 is larger than 1 which shows that 1/4 is greater than 1/8.
I hope this made sense. There's more than one way to solve these problems, so comment below if you would like me to explain it differently and I'll get back to you as soon as I can! :)
