Suppose has a solution. Explain why the solution is unique precisely when has only the trivial solution. Choose the correct answer.
Answer:
Because [tex]x = y[/tex], then the solution is unique.
Step-by-step explanation:
Given
[tex]Ax = b[/tex]
[tex]Ax=0[/tex]
See comment for complete question
Let there be two solutions x and y.
Such that:
[tex]Ax = b[/tex] and [tex]Ay = b[/tex]
Since:
[tex]Ax = Ay = b[/tex]
Then:
[tex]Ax - Ay = b - b[/tex]
[tex]Ax - Ay = 0[/tex]
This implies that:
[tex]Ax - Ay = A(x-y) = 0[/tex]
The only trivial solution is:
[tex]Ax - Ay = A(x-y) = 0[/tex]
Such that:
[tex]x -y = 0[/tex]
Then
[tex]x = y[/tex]
Because [tex]x = y[/tex], then the solution is unique.

What is the unknown of 8/10+____=97/100
Answer:
17/100
Step-by-step explanation:
The unknown quantity in the given expression is 17/100
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 8/10 + x = 97/100, we need to find x,
So,
8/10 + x = 97/100
Subtract 8/10 from both the sides,
8/10 + x -8/10 = 97/100-8/10
x = 97/100-8/10
Multiply by 100 both the sides,
100 x = 100(97/100-8/10)
100x = 97-80
100x = 17
Divide the equation by 100
x = 17/100
Hence, the unknown quantity in the given expression is 17/100

Find the measure for < LQR
Answer:
A
Step-by-step explanation:
90 - 12b = - 3b + 63
- 12b + 3b = 63 - 90
- 9b = - 27
- b = - 27/9
-b = -3
b = 3
to find the measure of MQR:
-3*3 + 63 = 54°
to find the measure of LQR:
180 - 54 = 126° + 1 = 127°
====================================================
Work Shown:
Angles MQX and LQR are vertical angles, so they are equal to one another.
angle MQX = angle LQR
-4a+139 = 4a+123
-4a-4a = 123-139
-8a = -16
a = -16/(-8)
a = 2
Use this to find each angle
angle MQX = -4a+139 = -4*2+139 = 131angle LQR = 4a+123 = 4*2+123 = 131We get the same value 131 each time, so this confirms we have the correct value for 'a', and it confirms our answer for angle LQR.

A recipe for a fruit drink calls for 2 cups of fruit juice for every 5 cups of water. Look at each drink mix. Does each drink mix follow the recipe?
4 cups of fruit juice and 10 cups of water. Yes. No.
0.5 cup of fruit juice and 1 cup of water. Yes. No.
1 cup of fruit juice and 2.5 cups of water. Yes. No.
7 cups of fruit juice and 17 cups of water. Yes. No.
Answer:
A. Yes
B. No
C. Yes
D. No
Step-by-step explanation:
A and C has an equivalent ratio.
B and D do not.
2:5 x2 = 4:10
Because if we multiply 2 on both the 2 cups of fruit juice and the 5 cups of water we'll get
4:10 which is the ratio of A
If we divide both the 2 cups of fruit juice and the 5 cups of water with 2 we'll get...
2 ÷ 2 = 1
5 ÷ 2 = 2.5
1:2.5 is the ratio for C.
So both C and A are correct
The rest, B and D, are not equivalent.
