Here is your answer:
7. 3×1=3
7×1=7
2. 5×1=5
7×1=7
=5 -2/7
Step one: write the equation
Step two: find the common denommarator (which is 7)
Step three: subtract 3-5= which equals to negative 2
Step four: subtract the whole numbers ( 7 and 2) which gives you five
Your answer is...
5 -2/7
Answer:
x = ±4i or x = ±√-16
Step-by-step explanation:
x² - 5x + 19 = 5x + 3
x² + 16 = 0
x² = -16
x = ±√-16 (a negative square root is an imaginary number)
Answer:
0.9697
Step-by-step explanation:
given that there is a fair coin and an unfair coin.
(both sides tails)
Let B = all tails 5 times
A1- fair coin
A2 - unfair coin
P(A1) = 0.5 and P(A2) =0.5 (since each coin is equally likely to be selected)
Required probability
= Prob (unfair coin/all tails) =P(A2/B)

Find y by maybe Pulling out like terms :
<span> 1.1 </span> Pull out like factors :
-y - 3 = -1 • (y + 3)
<span>Equation at the end of step 1 :</span><span>Step 2 :</span>Solving a Single Variable Equation :
<span> 2.1 </span> Solve : -y-3 = 0<span>
</span>Add 3 to both sides of the equation :<span>
</span> -y = 3
Multiply both sides of the equation by (-1) : y = -3
One solution was found : y = -3

-8x - 5y = 1
when x = 2
-8(2) - 5y = 1
-16 - 5y = 1
5y = -16 - 1 = -17
y = -17/5
