Answer:
the solution is (-1, 2)
Step-by-step explanation:
Let's solve the system
(3x + 4y = 5)
(2x - 3y = -8)
using the method of elimination by addition and subtraction. Notice that if we multiply all terms of the first equation by 3 and all terms of the second by 4, y as a variable will temporarily disappear:
9x + 12y = 15
8x - 12y = -32
-----------------------
17x = - 17, so x = -1.
Replacing x in the second equation by -1, we get:
2(-1) - 3y = -8, or
2 + 3y = 8,
or 3y = 6. Thus, y = 2, and the solution is (-1, 2).
Answer:
$4,800
Step-by-step explanation:
The maximum contribution for traditional IRA in 2019 = $6000
Given that;
karen has a salary of $33,000 and rental income of $33,000; then total income = $66,000
AGI phase-out range for traditional IRA contributions for a single taxpayer who is an active plan participant is $64,000 – $74,000.
PhaseOut can be calculated as: 
= 
= 0.2 * 6000
= 1200
Therefore, the maximum amount that Karen may deduct for contributions to her traditional IRA for 2019 = The maximum contribution for traditional IRA in 2019 - PhaseOut
= $6000 - $1,200
= $4,800
Answer:
≈ 1833
Step-by-step explanation:
To find ratio of proton mass to electron mass, we have to divide.
The numbers are given in <em>scientific notation</em>.
Let a number be
and another be
, when we divide, we will follow the rule shown below:

Now, we use the information given to find the ratio:

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
A - a removes both a’s from equation, then you’re left with b + bsquared, since they are unknown values you cannot combine them, even if it is the same letter, you can only add and subtract unknown values with their same letters together.
