Help please
Answer:
x = -2.04
y = - 0.408
Step-by-step explanation:
this is a solve by substitution problem. you know what x is from the first equation so you plug that into the second equation and solve for y. then when you know y you can plug y back into any equation to find x.
y=10(5y)+20 (substitute x)
y=50y+20 (subtract 50y from both sides)
-49y=20 (divide each side by -49)
y= -0.408
x=5(-0.408) (plug y in)
x= -2.04

I dong kno i need point im so sorry
3² x 5² is a multiplication of numbers, none of which are divisible by 2. Hence, the resulting number will be odd, as even numbers require a factor of 2.
The number Dawson wrote is the result of the factorization 3² x 5². Here, 3 and 5 are the bases and the exponents are 2. The exponentiation means the base number is multiplied by itself as many times as the value of the exponent. Therefore, 3² means 3 is multiplied by itself once, and 5² means 5 is multiplied by itself once.
In order to determine if the resulting number is even or odd, we don't have to perform the calculations. For any number to be even, it must be divisible by 2. If there isn't a factor of 2 in the number, the resulting product will be odd.
In this case, neither 3 nor 5 are divisible by 2. Hence, when you multiply them, no matter how many times, the result will always be an odd number. Therefore, the number obtained from 3² x 5² is odd.
