Solve the system of equations using the substituton method or the elimination method. You must use one of these methods in your written work. 4x + y = 23 y=x+8
Answer:
x = 3 and y = 11 is the answer.
in graph, this is an intersecting lines which means it has one solution.
Step-by-step explanation:
4x + y = 23
y = x + 8
arranged:
4x + y = 23
-x + y = 8
4x + y = 23
4 (-x + y = 8)
4x + y = 23
-4x + 4y = 32
———————
0 + 5y = 55
5y/5 = 55/5
y = 11
substitute:
y = 11
y = x + 8
11 = x + 8
11 - 8 = x
3 = x
There are 22 male lambs and 28 female lambs in a yard.
Ten males and 14 females have been shorn.
One of the lambs escapes from the yard.
What is the probability that it is a shorn male?
Answer:
shorn male = 20%
Step-by-step explanation:
The probability that the escaped lamb is a shorn male is 1/5 or 0.2, which is 20%.
To find the probability that the escaped lamb is a shorn male, we need to calculate the ratio of shorn male lambs to the total number of lambs.
Number of shorn male lambs = 10
Total number of lambs = 22 (male) + 28 (female) = 50
Probability = (Number of shorn male lambs) / (Total number of lambs)
Probability = 10 / 50
Probability = 1 / 5
So, the probability that the escaped lamb is a shorn male is 1/5 or 0.2, which is 20%.

Find the value of xx, yy, and zz in the parallelogram below.
Answer: x = 36, y = 10, and z = -25
Step-by-step explanation:
99 and -3z +6 are same side interior angles, so they sum to 180 degrees.
99 -3z + 6 = 180
-3z = 75
z = -25
Opposite angles of a parallelogram are congruent
2x + 9 = -3x + 6
2x + 9 = 75 + 6
2x = 81 - 9
2x = 72
x = 36
9y + 9 = 99
9y = 90
y = 10
According to definition of parallelogram

Answer:

Step-by-step explanation:
A
if the x-axis is the "mirror", then everything above the x-axis ends up below the x-axis with the same distances from x- and y-axis. and vice versa.
so, the y-value goes from y to -y. but the x-value stays the same, because nothing changed regarding the distance and left-right position from the y-axis.
B
if the y-axis is the "mirror", then everything right of the y-axis ends up left of the y-axis with the same distances from x- and y-axis. and vice versa.
so, the x-value goes from x to -x. but the y-value stays the same, because nothing changed regarding the distance and the above-below position from the x-axis.
C
this line is just going diagonally in 45° inclination from the bottom left to the top right (and passing through the origin, of course).
yes, everything you mirror around it, will simply go upside down, and the coordinates will trade places.
D
this should create a line perpendicular to the line in C, going diagonally with an inclination of -45° from top left to the bottom right.
as in C this makes the coordinates trade places, but it will not change its signs.

Answer: D. y= 15/x
Step-by-step explanation:
We have to test each explanation first, but I started with D because it is the most reasonable.
When you check the first column, you take 15 and divide it by 15. What do you get? 1.
1. X= 15 Y= 1 (15/15) = 1
When you check the second column, you take 15 and divide it by 5. What do you get? 3.
2. X= 5 Y= 3 (15/5) = 3
When you check the third column, you take 15 and divide it by 3. What do you get? 5.
3. X= 3 Y= 5 (15/3) = 5
When you use the fourth column, you take 15 and divide it by 1. What do you get? 15.
4. X= 1 Y= 15 (15/1) = 15
Since this all checks out, the answer is therefore correct.

PLEASE I NEED HELP QUICKLY!!! Find the solution for the given system of equations in the form (x,y). -x+y=8 7x+3y=-6
Answer:
The answer D is correct.
Step-by-step explanation:
-x + y = 8 ⇒ ( 1 )
7x + 3y = - 16 ⇒ ( 2 )
y = 8 + x ⇒ ( 3 )
Let us take equation 2 and let us replace y with (8+x).
Let us solve and find the value of x.
7x + 3y = -16
7x + 3 ( 8 + x ) = - 16
7x + 24 + 3x = -16
10x + 24 = -16
10x = -16 - 24
10x = -40
x = (-4)And now let us find the value of y.
For that, let us use equation (3)
Here, we have to replace x with -4 to find the value of y.
y = 8 + x
y = 8 - 4
y = 4Now we have to the answers in the form ( x , y )
Let us write.
( x , y ) ⇒ ( -4 , 4 )
