Answer:
X= 3
Y= -2
Has to be negative to be able to equal zero.
Answer:
x = 3
y = -2
Step-by-step explanation:
4x + 5y = 2........i
2x + 3y = 0........ii
Let's start by eliminating x, so we multiply i by 2 and ii by 4
2|4x + 5y = 2
4|2x + 3y = 0
So that we have
8x + 10y = 4..........iii
8x + 12y = 0..........iv
Subtracting iv from III, we have
-2y = 4
y = 4/-2
y = -2
Going ahead and substituting this value of y in eqn i, we have
4x + 5(-2) = 2
4x - 10 = 2
4x = 2 + 10
4x = 12
x = 12/4
x = 3

Which points are on the graph of the function rule f(x) = 10 – 4x?
A. (2, –18), (0, –10), (–2, –2)
B. (–2, 18), (0, 10), (2, 2)
C. (18, –2), (10, 0), (2, 2)
D. (–18, 2), (–10, 0), (–2, –2)
Answer: B. (-2, 18), (0, 10), (2, 2)
STEP 1: f(18)= 10 - 4 * 18= 10 - 72= -62... (18, 62)
STEP 2: f(-18)= 10 - 4 * -18= 10 - (-72)= 82... (-18, 82)
STEP 3: f(2)= 10 - 4 * 2=10- 8= 2... (2, 2)

1. Find the sum of the measures of the interior angles of a convex 11-gon.
Answer:
The measure of the sum of interior angles of a 11-gon is [tex]1620^{o}[/tex].
Each interior angle is approximately [tex]147.273^{o}[/tex].
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than [tex]180^{o}[/tex].
But,
sum of interior angles of polygon = (n - 2) x [tex]180^{o}[/tex]
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x [tex]180^{o}[/tex]
= 9 x [tex]180^{o}[/tex]
= [tex]1620^{o}[/tex]
Sum of angles of a 11-gon = [tex]1620^{o}[/tex]
To check: convex polygons' interior angles are less than [tex]180^{o}[/tex].
so that,
each interior angle of 11-gon = [tex]\frac{1620}{11}[/tex]
= [tex]147.273^{o}[/tex]

Suppose a is an irrational number
and is a rational number. Can
their sum be rational? Explain your
answer.
Answer:
The sum of a rational number and an irrational number is irrational
Step-by-step explanation:
By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal.
Example:
[tex]3+\sqrt{5} = 3+2.236067977...=5.236067977....[/tex]

4(2x - 3) = 6x + 2
Answer:
x =7
Step-by-step explanation:
Let's solve your equation step-by-step.
4 ( 2x − 3 ) = 6x + 2
Step 1: Simplify both sides of the equation.
4 ( 2x − 3 ) = 6x + 2
( 4 ) ( 2x ) + ( 4 ) ( −3 ) = 6x + 2 ( Distribute )
8x + −12 = 6x + 2
8x − 12 = 6x + 2
Step 2: Subtract 6x from both sides.
8x − 12 − 6x = 6x + 2 − 6x
2x − 12 = 2
Step 3: Add 12 to both sides.
2x − 12 + 12 = 2 + 12
2x = 14
Step 4: Divide both sides by 2.
2x / 2 = 14 / 2
x = 7

Nigel drew a parallelogram with a base length of 6 3/4 inches and a height of 2 5/8 inches. Krista made a scale drawing of Nigel's parallelogram using a scale factor of 1/3 .
Answer: Krista's drawing would have a base length of 2 and 1/4 inches and a height of 7/8 inches
Step-by-step explanation: First you do 6 divided by 3 which is 2 then you make 3/4 in twelfths and you get 3/12, then you simplify that into 1/4. Then
you combine those and get a base length of 2 and 1/4 inches.
Next, you do 2 and 5/8 divided by 3. Since 3 is less than 2 your answer would have to be less than 1. What i would do is make 2 and 5/8 into a fraction, which would be 21/8. then to make it easiest you multiply that by 1/3. which would equal 21/24. and then you simplify by dividing that by 3. Which would give you 7/8, which would give you your answer.
So the final answer would be a base length of 2 and 1/4 inches and a height of 7/8 inches.

1. The perimeter = 120 m; length = 45 m ; breadth = ____
2. Perimeter of a rectangle = 250 m; breadth = 50m; length = _____
1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5
2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

AB has endpoint A(-2, 3) and midpoint M(4,6).
Find the coordinates (x,y) of B.
Answer:
(10,9)
Step-by-step explanation:
4 = x-2/2
8= x-2
x = 8+2= 10
6= y+3/2
12 = y+3
y = 12-3 = 9
It is Given that AB has endpoint A(-2, 3) and midpoint M(4,6). then the coordinates (x,y) of B is (10,9)
What are the coordinates of midpoint of the line segment AB?Suppose we've two endpoints of a line segment as:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}[/tex]
and
[tex]y = \dfrac{q+n}{2}[/tex]
It is Given that AB has endpoint A(-2, 3) and midpoint M(4,6). we are asked to find the coordinates (x,y) of B.
Therefore,
For x; 4 = x-2/2
8= x-2
x = 8+2= 10
For y; 6= y+3/2
12 = y+3
y = 12-3 = 9
Hence, It is Given that AB has endpoint A(-2, 3) and midpoint M(4,6). then the coordinates (x,y) of B is (10,9)
