Find a solution to the linear equation-2x-2y=8 by filling in the boxes with a valid value of x and y
Step-by-step explanation:
If you want the "root" of the equation...
First get y by itself on one side. You should get y = - x - 8.
Notice that this is the equation of a straight line.
Then let y = 0, and solve for x. You should get x = -8.
So the solution or "root" of the equation is at the point (-8,0)
Answer:
X=0, y=0, x=3
Put the values into the equation. You should get -4,0
-2(-4) –2(0)=8

Chad bought 1 box of raisins. He gave 1/6 of it to one brother, 1/4 to another brother, and he kept the rest for himself. What fraction did he keep?
Write the answer in the simplest form
Answer:
He kept 7/12 of the box.
Step-by-step explanation:
We add and convert both 1/6 and 1/4 because we cant add fractions with unlike denominators.
1/6 = 2/12 | 1/4 = 3/12
then add.
2/12 + 3/12 = 5/12.
we subtract this from a whole, which is 12/12.
12/12 - 5/12 = 7/12
he keeps 7/12 of the box
hope this helped!

Step-by-step explanation:
good luck dude
Answer:
At approximately 5.1 hours, both hosts will charge about the same amount.
Step-by-step explanation:
First, form the equations for both hosts.
X represents hours and the number by itself (75, and 84) are the initial amount.
Host A: y = 12.25x + 75
Host B: y = 10.50x + 84
Now, we would set the equations equal to each other to solve for x, which will help us determine when both hosts will charge the same amount.
12.25x + 75 = 10.50x + 84
Subtract 10.50x and 75 from both sides.
1.75x = 9
Now, divide by 1.75.
x = 5.1428571428571428571428571428571
It says round to the nearest tenth, so we would round to 1 decimal place after the decimal.
x = 5.1
At approximately 5.1 hours, both hosts will charge about the same amount.

HELP ME HELP HELP Josiah has a mask collection. He keeps 117 of the masks on his wall, which is 65% of
his entire collection. What is the total number of masks in Josiah's collection?
Answer:
x=180
Step-by-step explanation:
Let us have x represent the entire mask collection
We know that 117 is 65% of his collection. We want to know the total number of masks he has
The equation we set up is:
117 is 65% of x: this translates to
117=0.65x, then we solve for x by dividing 0.65 by both sides
180=x
The total number of masks Josiah has is 180.

The length of a rectangle is 3 times its width the perimeter is 92 cm find the area
Answer:
The length of a rectangle is 3 times its width.
The perimeter is 92 cm.
Length --> x
Width --> 3x
Area of the rectangle --> y
so
3x·x = y
2(3x)+2x = 92 --> 6x + 2x = 92 -> 8x = 92 --> x =11.5 cm
so
y = 3(11.5)·11.5
y = 396.75 cm²
THE AREA IS 396.75 cm²
Answer:
Step-by-step explanation:
Let Width of rectangle =X
So length of rectangle =3x
Perimeter of rectangle=92
Perimeter of rectangle =2(length +width)
2(length+width)=92
2(3x+X)=92
8x=92
X=92/8
Width X=11.5cm
So length 3x=11.5×3
=34.5cm
Area of rectangle =34.5×11.5
=396.75cm^2
Decide which of the two given prices is the better deal and explain why. You can buy shampoo in a 6-ounce bottle for $2.29 or in a 15-ounce bottle for $.10.19
Answer:
The 6 oz bottle
Step-by-step explanation:
When you simplify it to see how much per ounce each costs, the 6-oz has the better price.
2.29/6 = 0.381666....
10.19/15 = 0.6793....
the second bottle cost more per ounce, so the 6 oz bottle has the better deal

how many terms do you have to compute in order for your approximation (your partial sum) to be within 0.0000001 from the convergent value of that series
Answer:
The answer is "4 terms".
Step-by-step explanation:
[tex]\sum_{n=1}^{\infty} \frac{(-1)^{n+2} (0.4)^{2n+1}}{(2n+1)!} \ \ \ \ \ error \leq 0.0000001\\\\\\\sum_{n=1}^{\infty} \frac{(-1)^{n+2} (0.4)^{2n+1}}{(2n+1)!} = \frac{-1^{0+2}}{1!}(0.4) + \frac{-1^{1+2}}{3!}(0.4)^3 +\frac{-1^{2+2}}{5!}(0.4)^5+\frac{-1^{3+2}}{7!}(0.4)^7+..\\\\[/tex]
[tex]=0.4 - \frac{0.4^3}{3!} + \frac{0.4^5}{5!} - \frac{0.4^7}{7!}+ \frac{0.4^9}{9!} - \frac{0.4^{11}}{11!}+............\\[/tex]
Note that, alternatively, positive and negative terms are given in the sequence. It is also alternating
Apply alternative test series:
[tex]\sum_{n=1}^{\infty} (-1)^{n-1} b_n = b_1-b_2+b_3-b_4+b_5-......+(-1)^{n-1} b_n >0\\\\i) b_{n+1}<b_n \ \ \ \ \forall_n \\\\ii) lim_{x\longrightarrow \infity} \ b_n = 0[/tex]
use alternating test method we get:
[tex]\sum_{n=1}^{\infty} \frac{-1^{n-1}}{n^2}\\\\s =0.4 - \frac{0.4^3}{3!} + \frac{0.4^5}{5!} - \frac{0.4^7}{7!}+ \frac{0.4^9}{9!} - \frac{0.4^{11}}{11!}+..\\\\b_5= \frac{0.4^9}{9!} = 0.00000000072 < \frac{1}{10^7} =0.0000001[/tex]
that's why its value is 4 terms
The approximation 0.0000001 within the convergent value of that series the fourth term.
What is an alternative test series?It is the convergent series when it is term decrease in absolute value and approaches the zero limit.
[tex]\sum_{n=1}^{\infty} \dfrac{(-1)^{n+2}(0.4)^{2n+1}}{(2n+1)!}[/tex]
When error ≤ 0.0000001
[tex]\begin{aligned} \sum_{n=1}^{\infty} \dfrac{(-1)^{n+2}(0.4)^{2n+1}}{(2n+1)!} &= \dfrac{(-1)^{0+2}}{1!}(0.4) + \dfrac{(-1)^{1+2}}{3!}(0.4)^{3} + ..............\\\\&= 0.4 - \dfrac{0.4^{3}}{3!} + \dfrac{0.4^{5}}{5!} - \dfrac{0.4^{7}}{7!} + ...............\end{aligned}[/tex]
Now by the alternative test series, we have
[tex]\Sigma _{n=1}^{\infty} (-1)^{n-1} b_n =b_1-b_2+b_3-b_4+....+(-1)^{n-1}b_n > 0\\[/tex]
Then
[tex]i) \ \ b_{n+1} < b_n \ \ \ \ \forall _n\\\\ii) \ \ lim_{x \rightarrow } b_n = 0[/tex]
Then by the alternative test method, we have
[tex]\sum_{n=1}^{\infty} \dfrac{(-1)^{n-1}}{n^{2}} \\\\s = 0.4 - \dfrac{0.4^3}{3!} + \dfrac{0.4^5}{5!} -\dfrac{0.4^7}{7!}+....\\\\b_5 = \dfrac{0.4^9}{9!} = 0.00000000072 < \dfrac{1}{10^7} = 0.0000001[/tex]

How do you add fractions?
Answer:
To add fractions, find the LCD (Least Common Denominator) or any common denominator of the fractions. For example, if you wanted to add 1/3+2/7, you find the LCD, which is 21, because 3x7=21, and 3 and 7 are both prime numbers. Now each fraction will have denominators of 21, so we will get 7/21+6/21. To add them together, add the numerators to get 13/21. Find the least common denominator of two fractions and then add the numerators. Hope it helps!

If Mr Mantle invests $15,000 in an account with 8% interest compounded
weekly how much would he have after 9 years?
a) $19,019,635.24
b) $16,119.74
c) $30,799.45
d) $30,798.77
Answer: c) $30,799.45
Step-by-step explanation:
Assuming there are 52 weeks in a year, the rate and time would be converted to;
Rate = 8%/52 = 8/52%
No. of periods = 9 years * 52 weeks = 468
The amount Mr Mantle would have is;
= 15,000 * ( 1 + 8/52%) ⁴⁶⁸
= $30,799.45276
= $30,799.45

For every left-handed person, there are about 4-right handed people. If there are 30 students in a class, predict the number of students who are right-handed.
Answer:
24 right handed students
Step-by-step explanation:
1. Out of every 5 students, 4 are right handed and 1 is left handed. We can say that 1/5 of the class is left handed.
2. Multiply 30 by 1/5 to get 6 left handed students in the class.
3. Take the 30 students in the class and subtract the 6 left handed students.
4. The remaining 24 students must be right handed.
