(-8) - 3y= 25
-8-3y= 25
move -8 to the other side
sign changes from -8 to +8
-8+8-3y=25+8
-3y= 33
divide both sides by -3 to get y by itself
and to get +y
-3y/-3= 33/-3
Answer:
y= -11
Answer:
x = 2.5 or -0.8
Step-by-step explanation:
Here, we are to use completing the square method to solve for the values of x
Firstly, we divide through by 4
= x^2 -7/4x -2 = 0
Now, we move the two term to the right hand side
x^2 -7/4x = 2
Now, we divide the coefficient of x by 2 and square it;
That would be;
(-7/4 * 1/2)^2 = 49/64
we now add this value to both sides of the equation
x^2 -7/4x + 49/64 = 2 + 49/64
The right hand side can be rewritten as;
(x-7/8)^2 = 177/64
taking the square root of both sides
x-7/8 = √(177/64)
x = 7/8 ± √(177/64)
x = 7/8 + √(177/74) or 7/8 - √(177/64)
= x = 2.53802 or -0.788017
Which to the nearest tenth is
x = 2.5 or -0.8
Answer:
4/9 is the answer
Hope it correct and it helps
Answer:
C) (14, 8, 10)
Step-by-step explanation:
the values in the parentheses go in order of the letters in the first equation
all you have to do is plug in the values
p+q+r=32. (14)+(8)+(10)=32
p-r=4. (14)-(10)=4
2p+q=36. 2(14)+(8)=36
Answer:
=250(1.025)∧4t
Step-by-step explanation:
Using the compound interest formula we can find the expression for the total amount that accumulates in the given time t.
A=P(1+R/n)ⁿᵇ
where A is the amount, P the principal amount, R the rate as a decimal n is the number of times it is compounded and b the time.
When compounded annually, the expression becomes
A=250(1.1)∧t
When compounded quarterly, we introduce the n in our expression.
A=250(1+0.1/4)∧4t
=250(1.025)∧4t
