Solve the following system of equations.
(15 Points)
x + 3y = -5 & 5y - 10 = -20x
Answer:
( 1 ; -2 )
Step-by-step explanation:
x + 3y = -5..............1
5y - 10 = -20x........2
x = -5 - 3y..............3
5y - 10 = -20( -5 - 3y)
5y - 10 = 100 + 60y
-55y = 110
y = -2
x = 1

Answer:
D
Step-by-step explanation:
We can use d to find out how much x equals which therefore would solve the rest of the equation. We also know that half of a parallelogram= 180 degrees so we know that it wouldn't be c and it wouldn't be any of the others either.

Answer:
24√3 square units
Step-by-step explanation:
The side length of a regular hexagon is 2/√3 times the length of the apothem. For an apothem of 2√3, the side length is ...
s = (2/√3)(2√3) = 4
The perimeter P of the hexagon is 6 times the side length, so is 6×4 = 24.
The area is given by ...
A = 1/2Pa
where P is the perimeter and 'a' is the apothem.
A = 1/2(24)(2√3) = 24√3
The area of the hexagon is 24√3 square units.
_____
A hexagon can be divided into 6 congruent equilateral triangles. The apothem will be the altitude of one of those, so will divide the triangle into two triangles with angles 30°, 60°, and 90°. The ratios of the side lengths of such a triangle is something you might want to remember: 1 : √3 : 2. The altitude corresponds to the "√3" side, and the side length of the equilateral triangle corresponds to the "2" side. That is, we have the proportion ...
apothem : hexagon side = √3 : 2
Multiplying by 2 gives the actual values in the hexagon of this problem:
apothem : hexagon side = 2√3 : 4

Answer:
18
Step-by-step explanation:
We know that line FH total length is 49. We also know that the length of line GH is 31.
To find FG, all we need to do is subtract 49-31 to find the length of FG.
Line FG total length is 18.

how to solve this problem 3x+5=2x+1
Answer:
Step-by-step explanation:
Simplifying
3x + 5 = 2x + 1
Reorder the terms:
5 + 3x = 2x + 1
Reorder the terms:
5 + 3x = 1 + 2x
Solving
5 + 3x = 1 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
5 + 3x + -2x = 1 + 2x + -2x
Combine like terms: 3x + -2x = 1x
5 + 1x = 1 + 2x + -2x
Combine like terms: 2x + -2x = 0
5 + 1x = 1 + 0
5 + 1x = 1
Add '-5' to each side of the equation.
5 + -5 + 1x = 1 + -5
Combine like terms: 5 + -5 = 0
0 + 1x = 1 + -5
1x = 1 + -5
Combine like terms: 1 + -5 = -4
1x = -4
Divide each side by '1'.
x = -4
Simplifying
x = -4
Answer:
x = -4
Step-by-step explanation:
To solve the given equation, we must find a value of x that satisfies the equation.
3x + 5 = 2x + 1
Subtract 2x from both sides.
x + 5 = 1
Subtract 5 from both sides.
x = -4
So the value of x that satisfies the equation is -4. So the solution to the equation would be x = -4.

Two points that are on the same line are called what?
A
coplanar
B
collinear
C
supplementary
D
parallel
Answer:
That would be B Collinear
Answer:
B: Collinear
Step-by-step explanation:
Let's look at the answer choices, shall we?
-Coplanar is two lines or points on the same plane.
-Supplementary is where two angles measure to 180 degrees
- Parallel lines are where two lines have the same slope and will never intersect
The only other option is collinear, which happens to have the definition of two points on the same line.

Which expression does not belong with the other three?
Answer:
I think is the one with parenthesis
3^10 + 3^10 + 3^10=
a)9^30
b)3^30
c)9^10
d3^11
Answer:
As a^m+a^m+a^m=a^m+m+m or (a+a+a)^m {WHEN BASES ARE SAME WE CAN ADD THE BASES TOGETHER AND PUT THE POWER (IN CASE OF ADDITION) AND WHEN POWERS ARE SAME WE CAN ADD THE POWERS AND LET THE BASE REMAIN SAME}
So,
(3+3+3)^10 and 3^10+10+10 is also true (only because both the basesa nd the powers here are the same)
So,
9^10 and 3^30
So option b and c are correct
3. The average rate of change of the function f(x) on the interval -2 is less than or equal to X which is less than or equal to 4 is -3.5. If f (4)=11 then which
of the following is the value of f(-2)?
(1) -11
(3) 21
(2) -21
(4) 32
The value of the function f(x) at x = - 2 is equivalent to 32.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that the average rate of change of the function f(x) on the interval -2 is less than or equal to [x] which is less than or equal to 4 is -3.5.
In the range of {- 2 ≤ x ≤ 4}, the rate of change of f(x) is -3.5. This means we can write -
r = {f(4) - f(-2)}/(4 + 2)
f(4) = 11 and [r] = - 3.5. So, we can write -
- 3.5 = {11 - f(-2)}/6
11 - f(-2) = -3.5 x 6
11 - f(-2) = - 21
f(-2) = 11 + 21
f(-2) = 32
Therefore, the value of the function f(x) at x = - 2 is equivalent to 32.

The ratio of girls to boys in a school simplifies to 2:3. How many boys are there if there are 345 students in the school?
Answer:
230
Step-by-step explanation:
You should multiply 345 by 2/3 or you can divide 345 by 3, which equaks 115 and then multiply 115 by 2 which equals 230.
The number of boys in the school is 207.
Given
The ratio of girls to boys in a school simplifies to 2:3.
We need to find out how many boys are there if there are 345 students in the school.
What are ratios?The ratio gives us an idea between two quantities.
It is denoted by a:b
Example:
The ratio of apple and mango in the basket is 1:2.
The total number of fruits is 12.
Apple = [ 1 / (1+2) ] x 12 = (1/3) x 12 = 4
Mango = [ 2/(1+2) ] x 12 = (2/3) x 12 = 2 x 4 = 8
We have,
Total number of students = 345
The ratio of girls to boys = 2:3
The number of boys :
= [ 3 / (2+3) ] x 345
= [ 3/5 ] x 345
= 3 x 69
= 207
Thus the number of boys in the. school is 207.
