Answer:
Are you sure the question is right?
Answer:
b.
Step-by-step explanation:
Hi there
One pound of salmon will cost $13, and one pound of tuna will cost $8.
Here's why.
X will be the cost of pound of salmon, and y will be the cost of a pound of tuna.
| 15x+8y=259
| 12x+6y-204
6y = 204-12x
y=34-2x
15x+8(34-2x)=259
272-259=16x-15x
x=13
y=34-2*13
y=34-26
y=8
So, again...
1lb Salmon : $13
1lb Tuna : $8
You have to complete the square. When you do this you get an equation that looks like this: (x-3)^2 + (y+4)^2 = 4. So your center is (3, -4) and your radius is 2. That looks like B to me!!!
Given:
To find:
The measure of angle MFZ.
Solution:
In triangles MFZ and PFZ,
(Right angle)
(Given)
(Common side)
(HL congruent postulate)
(CPCTC)
The value of x is 10.
The measure of angle MFZ is:
Therefore, the measure of angle MFZ is 19 degrees.
