9(8-x) =3x
Answer:
x=6
Step-by-step explanation:
I don't know if you are solving for x but x=6
9(8 - x) = 3x
Multiply 9x8 and 9-x
72 - 9x = 3x
Add the 9x
72 = 3x + 9x
Add 3x+9x
72 = 12x
Divide 12x/12 and 72/12
12x/12 = 72/12
x = 6
Answer:
9(8 - x) - 3x
⇛72 - 9x - 3x
⇛72 - 12x
⇛12x = 72
⇛x = 72/12
Therefore, x = 6. Ans.

Use the expression -1/3 - (-5/12)
Answer:
__
[tex]\large\boxed{\mathfrak{0.08333}}[/tex]
Step-by-step explanation:
Answer:
1/12
Step-by-step explanation:
Subtract negative is addition: -1/3 - (-5/12) = -1/3 + 5/12
1/3 = 4/12
-4/12 + 5/12 = 1/12

find a series expansion for pi using the Maclaurin expansion for arctan(x) and the fact that tan(pi/4)
Recall that for |x| < 1, we have
[tex]\displaystyle \frac1{1-x} = \sum_{k=0}^\infty x^k[/tex]
It follows that, for |-x²| = |x|² < 1, or just |x| < 1,
[tex]\displaystyle \frac1{1+x^2} = \frac1{1-(-x^2)} = \sum_{k=0}^\infty (-x^2)^k = \sum_{k=0}^\infty (-1)^k x^{2k}[/tex]
Taking the antiderivative of both sides gives us
[tex]\displaystyle \arctan(x) = C + \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
where C is a constant, which we determine to be 0, since taking x = 0 on both sides makes the series vanish, while arctan(0) = 0 since 0 = tan(0). So
[tex]\displaystyle \arctan(x) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
Since tan(π/4) = 1, it follows that π/4 = arctan(1), so in the series we replace x = 1, then solve for π :
[tex]\displaystyle \arctan(1) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} 1^{2k+1}[/tex]
[tex]\displaystyle \frac\pi4 = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1}[/tex]
[tex]\displaystyle \pi = \sum_{k=0}^\infty \frac{4(-1)^k}{2k+1}[/tex]
[tex]\pi = 4 - \dfrac43 + \dfrac45 - \dfrac47 +\cdots[/tex]
y=varies directly as x, if y=22 when x=-11, find x when y=88
Answer:
x=-44
Step-by-step explanation:
y=22 x=-11
y=88 x=?
y/x=22/-11=-2
88/x=-2
-2x=88
x=-44

Brian invests £990 into his bank account. He receives 5.2% per year simple interest. How much will Brian have after 2 years?
Answer:
£1092.96
Step-by-step explanation:
Amount of money Brian has after 2 years
= 2(5.2% × £990) + £990
= £102.96 + £990
= £1092.96
What is an equation of the line that passes through the point (-7,-6)(−7,−6) and is parallel to the line x-y=7x−y=7?
Answer:
y = x + 1
Step-by-step explanation:
The gradient of a line can be defined by the equation:
m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript
For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):
x2 = -7, y2 = -6
Plug these values into the formula above:
m = (y-(-6)) ÷ (x-(-7))
m = (y+6) ÷ (x+7)
At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.
x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:
y = x-7 ---> The gradient (coefficient of x) is 1.
Therefore, the gradient of the other parallel line must also be 1.
This can be substituted into the previous equation to give:
1 = (y+6)÷(x+7)
x+7 = y+6
x+1 = y
Therefore, the answer is y=x+1
