Answer:
(-3,-43) and (3,107)
Step-by-step explanation:
input 25x+32 for y
25x+32=5x²+25x-13
32=5x²-13
-5x²=-45
x²=9
x=+-3
which means you separate the solution
x= -3
x= 3
then input the answers you got for x, in both equations. Then you'll get your y.
y=25(-3)+32
-43
Then check your answer.
Then input the other answer you got for x.
I may be wrong, but I tried and checked my answers.
Answer:
10
Step-by-step explanation:
Answer:
x = 8/7
Step-by-step explanation:
3(x - 2) + 6 = 4(2 - x),
3x - 6 + 6 = 8 - 4x,
7x = 8,
x = 8/7
Thousands is a word to describe number with 1000 value and tens used for the number with 10 value. First, you need to count how much 500 tens is. The calculation would be: 500 * 10= 5000.
Then to convert it into thousand, you need to divide it with 1000. The calculation would be: 5000/1000 = 5 thousands
