Answer:
Step-by-step explanation:
A quadratic equation has one root if the discriminant is 0.
That is we need 
for this particular question.
Compare the following to find 
:
The variable 
is representative of the variable 
here.
Plug in into :
Subtract 4 on both sides:
Divide both sides by 16:
Reduce:
An isosceles triangle has 2 equal sides and 2 equal angles
From my research, the original system of equations contain the following equations:
<span>2x − y = −4
3x + 5y = 59
where obtained solution is x = 3
Among the choices, it is easier to substitute </span><span>3x + 5y = 59 with one of the choices to see if they yield the same solution set. From trial-and-error, the equation that can replace the original equation is " 13x = 39 ". Among the choices, it is the 4th choice.</span>
Caiden's balance after 5 years would be $831
<u>Explanation:</u>
Given:
Principal, p = $475
Rate of interest = 3.8%
time, t = 15 years
Balance after 15 years = ?
We know:
where,
n = number of compounding periods
r = rate of interest
t = number of years
Substituting the value;
Therefore, Caiden's balance after 5 years would be $831
Answer:
4 + 1 + 20 + 100 = 1000
5 + 20 + 100 = 1000
25 + 100 = 1000
125 = 1000
The equation would be false because 125 does not equal 1000
Step-by-step explanation:
