- 8x + 2y = -20
8x - 5y = 14
Answers
Answer:
x = 3, y = 2
Step-by-step explanation:
~ Through process of elimination ~
1. - 8x + 2y = -20
+ 8x - 5y = 14
2. Simplify to solve for y through simple algebra:
2y - 5y = -20 + 14 ⇒ - 3y = - 6 ⇒ y = 2
3. Now substitute this value of y into the to equation - 8x + 2y = -20 to get x:
- 8x + 2 ( 2 ) = -20 ⇒
-8x + 4 = -20 ⇒
-8x = -24 ⇒
x = 3

Step-by-step explanation:
The distance between D and G is:
[tex]\sqrt{(-1-(-10))^2+(3-1)^2}=\sqrt{9^2+2^2}=\sqrt{81+5}=\sqrt{86}[/tex]
If point J is not exactly this far, then it is not on the circle.
[tex]\sqrt{(-1-(-3))^2+(12-3)^2}=\sqrt{2^2+9^2}=\sqrt{5+81}=\sqrt{86}[/tex]
Therefore, it is on the circle. Hope this helps!

No, $20 is not enough to buy lunch for a week.
What is comparison?Comparing numbers in maths, defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given that, A student has an allowance of $20 a week. He wants to buy lunch at school for $3.50 every day.
Since, there is off on Sundays in a school, so we will consider 6 days in week.
3.50x6 = 21
That means he need $21 to buy lunch for the week
21>20
Hence, $20 is not enough to buy lunch for a week.

Question:
Which expressions are equivalent to ½ + 3c + ⅘.
Check all that apply.
Answer:
½ + 3c + ⅘ is equivalent to
1. ⅒(30c + 13)
2. 3c + 13/10
Step-by-step explanation:
The options are not well presented.
However, I'll give simplify the given expression in the question above.
Given: ½ + 3c + ⅘.
Required: Simplify
We start by collecting like terms
3c + ½ + ⅘
From this point, the expression can be solved in two ways
1. Solve fractions
This gives [Find LCM]
3c + (5 + 8)/10
3c + 13/10
3c + ⅒(13)
This can still be solved further [Find LCM]
(30c + 13)/10
⅒(30c + 13)
Hence ⅒(30c + 13) is equivalent to ½ + 3c + ⅘.
2. Convert fractions to decimal
½ + 3c + ⅘ becomes
0.5 + 3c + 0.8
Collect like terms
3c + 0.5 + 0.8
3c + 1.3
Convert decimal to fraction
3c + 13/10
3c + ⅒(13)
This can still be solved further [Find LCM]
(30c + 13)/10
⅒(30c + 13)
Hence ⅒(30c + 13) is equivalent to ½ + 3c + ⅘.
This is as far as the expression can be evaluated

Answers
On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi.
Which is the graph of the given function?Here we have the function:
y = cos(2*(x + pi))
First, let's distribute the product in the argument of the cosine:
y = cos(2x + 2pi).
Now, notice that 2pi is the period of a cosine function, then:
cos(2x) = cos(2x + 2pi)
Then we can write:
y = cos(2x)
Now, the y-intercept is:
y = cos(2*0) = 1
And because the factor of 2 inside the argument, it goes through 2 cycle at 2pi (instead of 1 cycle, like a normal cosine).
Then the correct option is:
"On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi."

During the first few years of a tree's life, its growth rate is linear. For example, an oak tree grows at a rate of 1.5 feet per year for the first twelve years. Mostafa plants a maple tree in his backyard and measures its height at 4 feet. Two years later, Mostafa measures the tree again and finds that its height is now 6.5 feet. Which statement is correct given this information?
Answers
Answer:
Mostafa's maple tree grows at a slower yearly rate than an oak tree.
Step-by-step explanation:
Given that:
An oak tree grows at a rate of 1.5 feet per year for twelve years;
After 12 year; the oak tree will be = 12 × 1.5 = 18 feet per year.
Now; we are being told that Mostafa plants a maple tree at his backyard and measures its height at 4 feet.
i.e x years = 4 ft
two years later ; it height is now 6.5 ft
thus;
x year = 4 ft
x + 2 = 6.5 ft
[tex]6.5 * x = (x+2)4\\ \\ 6.5 x = 4x + 8\\ \\ 6.5x-4x = 8\\ \\ 2.5x = 8\\ \\ x = \dfrac{8}{2.5}\\ \\ x = 3.2[/tex]
Thus ; Mostafa first measured the height of the tree when it is 4 ft at the age year of 3.2
So;
if 3.2 year = 4 ft
1 year = x
x = [tex]\dfrac{4 *1 }{3.2}[/tex]
x = 1.25 ft
So if an oak tree grows at the rate of 1.5 ft in a year.
Then, Mostafa's maple tree grows at the rate of 1.25 ft in a year.
From the given information in the diagram attached below; we can infer that :
Mostafa's maple tree grows at a slower yearly rate than an oak tree.
