Simplifying
3x + 2y = 35
Solving
3x + 2y = 35
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 35 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 35 + -2y
3x = 35 + -2y
Divide each side by '3'.
x = 11.66666667 + -0.6666666667y
Simplifying
x = 11.66666667 + -0.6666666667y

3. A rumour is being spread in a community that the president is going to retire before the next election 2015. Initially 2 people were told the rumour and each of these people told 2 others the following day. Each of the 2 people told by the initial people told 2 others the day after they were told. If this process keeps up, how many people will be told the rumour on the fifth day?
Answer:
I'm not sure if that's what is meant cuz the text is a little ambiguous
Nevertheless, 62 people
Step-by-step explanation:
Amount = 2 + 4 + 8 + 16 + 32 =62 people
"Exponential Growth"
Answer:
62
Step-by-step explanation:
You start with 2 people on day 1. On day 2 each one of them tells 2 other people, which means 4 new people are told the rumor. We can use the formula p(d)= n + n^n + n^(n+1) + n^(n+2).... d times, where p(d) is the number of people told the rumor on the day d, n being the Number of people told by each person every day, as well as the initial people. So the formula is
p(5)= 2 + 2^2 + 2^3 + 2^4 + 2^5 = 2+4+8+16+32 = 62
62 people are told the rumor on the fifth day.

A square purple rug has a orange square in the center. The side length of the orange square is x inches. The width of the purple band that surrounds the orange square is 12 in. What is the area of the purple band?
Answer:
578 + 48 square inches
Step-by-step explanation:
The computation of the area of the purple band is as follows:
Area of the green square = side^2 = x^ square inches
And, the area of the orange square = side^2
The side would be = = 12 + 12 +x = 24 + x
And, now the area would be = (x + 24)^2
Now the area of the orange band is
= Area of the orange square area of the green square
= (x + 24)^2 - x^2
= x^2 + 24^2 + 48 - x^2
= 578 + 48 square inches
Solve the equation.
4y^3 – 7y^2 + 28 = 16y
Answer: -2, 2, 7/4
***If the pictures is sideways, use the rotate button. I hope the explanation made sense!
Answer:
The roots are y=2, y=-2 and y=7/4
Step-by-step explanation:
4y^3-7y^2+28=16y =0
subtract 16y from both sides
4y^3 -7y^2 - 16y +28 =0
Factor by Grouping
(4y^3 -7y^2) (-16y +28) =0
Greatest common factor
y^2(4y-7) -4(4y-7)
take y^2 and -4 as well as the repeated 4y-7
(4y-7) (-4+y^2)
change -4 to -2^2
(4y-7) (-2^2+y^2)
Similify
(4y-7). (y-2). (y+2)
y=7/4 y=2 y=-2

What is the value of f(−6) when f(x)=x2+8x+10?
Answer:
-2
Step-by-step explanation:
given:
f(x) = x² + 8x + 10
for f(-6), simply substitute x = -6 into the right side of the equation
f(-6)
= (-6)² + 8(-6) + 10
= 36 - 48 + 10
= -2

Answer:
41, 51 and 52
Step-by-step explanation:
65% of 80 = 52
65 x 80 / 100 = 52
82% of 50 = 41
82 x 50 / 100 = 41
170% of 30 = 51
170 x 30 / 100 = 51
Answer: 82% of 50 (least) 170% of 30 (middle) 65% of 80 (greatest)
Step-by-step explanation:
All you need to do is put in the percentages of the number that it is of. Hope this is the answer your looking for.

Solve 3x^2+4=436
Please solve step by step
Answer:12
Step-by-step explanation:
Your goal with variables should always be to isolate them.
so the first step is to subtract the 4
3x^2+4=436
-4= -4
3x^2=432
The next step to isolate the variable x is to get rid of the 3. To get rid of the 3 you have to divide both sides by 3 since it is the opposite of multiplying.
3x^2=432
/3. =/3
x^2=144
the last step to isolate the x is to do the opposite of what an exponent is, which is to find the square root. So when you square the x^2, the exponent cancels out.
square root of x^2=x
square root of 144=12
x=12

4.) Together Alice & Mindy have saved $490 for a trip this summer.
Amy has saved $54 more than Mindy. How much has each person
saved? Write a system & use substitution to solve.
Answer:
Mindy=191
Amy=299
Step-by-step explanation:
first you want to divide $490 in half to see what each person has. Thats 245 and since Amy has $54 more, you minus 54 from 245 to get 191. So while Mindy has 191, Amy has 299
