Check all of the points that are solutions to the system of inequalities.

Mathematics
1 answer:
Setler [38]3 years ago
8 0

Answer:

C and F

Step-by-step explanation:

To be a solution of the inequality, we just plug in the point into the original system. For example, let's look at A. Let's plug in x = 1 and y = 1. We get 1 ≤ 5 + 4 and 1 > -3 + 4. These simplify to 1 ≤ 9 and 1 > 1. Since 1 > 1 is a false statement, A is not a solution. Following this process, we get:

A: Not a solution

B: Not a solution

C: Solution

D: Not a solution

E: Not a solution

F: Solution

What must be the length of ZY in order for ZY to be tangent
Nata [24]

Answer:

15 units

Step-by-step explanation:

The picture of the question in the attached figure

we know that

Triangle XYZ is a right triangle, because segment ZY is tangent to circle X at point Y

so

Applying the Pythagorean Theorem

XZ^2=XY^2+ZY^2

we have

XZ=8+9=17\ units\\XY=8\ units

substitute the given values

17^2=8^2+ZY^2

ZY^2=289-64\\ZY^2=225\\ZY=15\ units

amm1812

Answer:

Option C,17% is correct

Step-by-step explanation:

The tax on his investment is  15% of his long-term gains on investment since his total taxable income is  $77,000 ($75,000+$2,000).

tax on investment gain=15%*$2000=$300

after tax gain on investment =$2000-$300=$1700

The return on investment of $10,000=after tax gain on investment/cost of investment

after tax gain is $1700

cost of investment is $10,000

return on investment=$1,700/$10,000=17%

The correct option is C,17% return on investment of $10,000
