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:
The equation of circle C is ( x-5 )2 + ( y-7 )2 = 80 .
Step-by-step explanation:
Well,
We can see that there are 8 10's and 3 1's. So we can write 8 10's followed by 3 1's and join them with addition symbols.
83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1
Answer:
Probability of a dice rolling a number less than 3 is 2/6 = 1/3
Probability of dice spinning a number less than 6 is 5/6
Step-by-step explanation:
Number less than 3:
Chances of no. Being 1 and 2, not including 3, is 1/6 individually.
Hence, chances of no. Rolled being lesser than 3 is 1/6 + 1/6 = 1/3
Probability of no. Being smaller than 6 (lesser than 6) Aka spinning 1 or 2 or 3 or 4 or 5, not including 6 is (1/6) x 5 = 5/6
Parent function: y=2^x
