Answer:
x^2+3x+2x+1 is meant to be x^2 +5x+1
Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a
[ = 1 ] , that is
a = 4 , so
y = 4
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
= b , that is
b = 5
then exponential function is
y = 4 . 
Answer:
0.706
Step-by-step explanation:
Convert 12/17 to decimal by dividing the numerator by denominator.
12 ÷ 17 = 0.70588.......
The nearest thousandth is the third decimal place.
If we round up: 0.706
If we round down: 0.705
Because the fourth digit is "8", we round up.
If the digit after the one you want to round to is 5 or greater, then you round up. If the digit after is 4 or less, round down..
12 ÷ 17 = 0.70588....... ≈ 0.706
I rounded the answer I got which is 1.6 or 1.60
10x - 7y = -1....multiply by -1 to make that -7y positive
-2x - 7y = -25
------------------
-10x + 7y = 1 (result of multiplying by -1)
-2x - 7y = -25
-----------------add
-12x = - 24
x = 2
-2x - 7y = -25
-2(2) - 7y = -25
-4 - 7y = -25
-7y = - 25 + 4
-7y = - 21
y = 3
solution is : (2,3)
