Let's solve your equation step-by-step.4(1−x)+2x=−3(x+1)Step 1: Simplify both sides of the equation.4(1−x)+2x=−3(x+1)Simplify: (Show steps)−2x+4=−3x−3Step 2: Add 3x to both sides.−2x+4+3x=−3x−3+3xx+4=−3Step 3: Subtract 4 from both sides.x+4−4=−3−4x=−7Answer:x=−7

Given the two options above, in order to come up with the best plan we have to calculate the future value of money in each plan.
compound interest is given by: $FV=p(1+ \frac{r}{100})^n$

Option 1
p=$500
r=2%=0.02
t=1 year
$FV=500(1+0.02)^1=$510$

Option 2
p=$500
r=2/12=1/6
n=1*12=12
hence:
$FV=500(1+\frac{ \frac{1}{6}}{100})^{12}
$
=$509.09
Comparing the two plans above, option 1 is the best.

b] Option 1 is the best because she will secure $510 as compared to option 2 which has interest rate that reduces her amount by $1 after one year due to annual charges. The total amount of money she will have at the end of the plan is $510.

What is x/13-5=25/26

Juliette [100K]

$\frac{x}{13} -5=\frac{25}{26}$ Add 5 on both sides

$\frac{x}{13}=\frac{25}{26}+5$ Make the denominators the same

$\frac{x}{13}=\frac{25}{26}+\frac{130}{26}$

$\frac{x}{13}=\frac{155}{26}$ Multiply 13 on both sides

$(13)\frac{x}{13}=(13)\frac{155}{26}$

$x=\frac{2015}{26}$

$x=\frac{155}{2}$

Prove that 1+cosA/sinA + sinA/1+cosA=2cosecA

Alla [95]

$\frac{1+cos\alpha}{sin\alpha}+\frac{sin\alpha}{1+cos\alpha}=2cosec\alpha\\\\L=\frac{(1+cos\alpha)(1+cos\alpha)+sin\alpha\cdot sin\alpha}{sin\alpha(1+cos\alpha)}=\frac{1+2cos\alpha+cos^2\alpha+sin^2\alpha}{sin\alpha(1+cos\alpha)}\\\\=\frac{1+2cos\alpha+1}{sin\alpha(1+cos\alpha)}=\frac{2+2cos\alpha}{sin\alpha(1+cos\alpha)}=\frac{2(1+cos\alpha)}{sin\alpha(1+cos\alpha)}\\\\=\frac{2}{sin\alpha}=2\cdot\frac{1}{sin\alpha}=2cosec\alpha=R$

What is the inverse of the given relation? y = 4x - 8

Aleks [24]

Let y be x, and x be y.

x = 4y - 8

Rearrange to make y the subject.

x + 8 = 4y

Therefore

y = (x + 8) / 4

is the inverse.
