Answer:
To find the point of intersection, just solve for x and y in the equations
so since x - y = -5
x = y - 5
now that we have a value of x, we will substitute x with in in the other equation
<em>5x + 3y = -9</em>
<em>5(y-5) + 3y = -9</em>
<em>5y - 25 + 3y = -9</em>
<em>8y = 16 </em>
y = 2
now use this value of y in the equation we made for x
<em>x = y - 5</em>
<em>x = 2 - 5</em>
x = -3
Hence, the point of contact is (-3 , 2)
Answer:
10) area of 130° segment 4.5 in²
Step-by-step explanation:
10) area of full circle = πr² = (3.14)(2²) = 12.56 in²
area of 130° segment = (130/360)(12.56) = 4.54 in²
Answer: First one is 140, second one is 70
Step-by-step explanation: They’re corresponding angles
P,Q,R can't be 0, because their product is nonzero. Either of S and T could be 0, but the third one only works if S is 0.
