STEP 1: Multiply second equation by -3.
After multiplying we have the following system:
3x+4y−3x+3y=8=−36
STEP 2: add the two equations together to eliminate x from the system.
7y=−28
STEP 3: find y
<u>y=−4</u>
<u></u>
STEP 4: substitute the value for y into the original equation to solve for x.
3x+4(−4)=8
<u>x=8</u>
<span>A rectangle is a regular polygon only if it is also a square. A rectangle that is not a square is not regular. </span>
Step-by-step explanation:
the length of AB = √(9+3)²+(5-9)²
= √144+16=√180 = 6√5
the length from A to E = ⅜× 6√5
= 2.25 √5 or 5.03
Answer:
irrational numbers
Step-by-step explanation:
I hope I'm correct, sorry if I'm wrong
to solve
f(x)=15000+1.5x
<span>replace f(x) with y
switch x and y
solve for y
replace y with f</span>⁻¹(x)
f(x)=15000+1.5x
replce f(x) with y
y=15000+1.5x
switch x and y
x=15000+1.5y
solve for y
y=(x-15000)/1.5
f-1(x) = (x-15000)/1.5
<span>The variable x
represents the spending limit on johns credit card In the inverse
function.</span>
If johns
spending limit is $60000, his monthly income is (60000-15000)/1.5=$30000
If johns
spending limit is $60,00, his monthly income is (60-15000)/1.5= -$9960------
>the johns spending limit must be >$15000
