Answer:
Step-by-step explanation:
We are given the equations:
Since we know what y is equal to, we can substitute that expression in for y in the first equation.
Distribute the 2. Multiply each term inside the parentheses by 2.
Combine the like terms (the terms with variables).
Since we are solving for x, we must isolate the variable. 38 is being subtracted and the inverse of subtraction is addition. Add 38 to both sides.
Now x is being multiplied by 9. The inverse of multiplication is division. Divide both sides by 5.
Now we know what x is equal to and can substitute the value into the second equation.
Multiply.
Subtract.
Coordinate points are written as (x,y). Therefore, the solution is (5, -4).
Answer:
3 / 512
Step-by-step explanation:
If you want to simplify further, reduce the exponents:
2²/2¹⁰ + 2²/2¹¹
1/2⁸ + 1/2⁹
Find the common denominator and add.
2/2⁹ + 1/2⁹
3/2⁹
3/512
The measure of AN form the given figure is 2. 5cm. Option D
<h3>How to determine the length</h3>
It is important to note that if from one external point, two tangents are drawn to a circle then they have equal tangent segments.
We have that,
AM ≅ AN
so, if AM measures 2. 5cm
AN measures 2. 5cm
Thus, the measure of AN form the given figure is 2. 5cm. Option D
