Answer:
x = 3
Step-by-step explanation:
I'm going to use the method of elimination by multiplying the second equation by -3:
Then I can eliminate x:
-32y = -64
To solve for y, I'd simply divide:
y = 2
Because I now have y = 2, I'll just plug in 2:
6x - 5(2) = 8
6x - 10 = 8
6x = 18
x = 3
Hopefully I helped :)
Answer:
It’s 4
Step-by-step explanation:
2+2=4

The product is less than either of the factors. Multiplying a number < 1 with 2/3 another number < 1, will give a fraction of a fraction, and part of a fraction is an even smaller fraction. Another way of looking at it: Fractions less than one have numerators smaller than their denominators. When multiplying fractions, you multiply across, so multiplying two fractions that are both less than one will always give a numerator much smaller than the denominator, and a larger denominator makes for a smaller number. I hope this helps, but if you have questions, ask.
Answer:
-2x^2 + 3x -1
Step-by-step explanation:
y = ax^2 + bx + c
(0,-1):
-1 = a(0)^2 + b(0) + c
-1 = 0 + 0 + c
-1 = c
(1,0):
0 = a(1)^2 + b(1) + c
0 = a + b + c
(2,-3):
-3 = a(2)^2 + b(2) + c
-3 = 4a + 2b + c
Replace c with -1
0 = a + b -1
1 = a + b
-3 = 4a + 2b -1
-2 = 4a + 2b
-1 = 2a + b
Solve:
2a + b = -1
-1a - b = -1
a = -2
2a + b = -1
-2a -2b = -2
-b = -3 divide both by -1: b = 3
a = -2; b = 3; c = -1
y = ax^2 + bx + c or y = -2x^2 +3x -1
4 1/5*5/14
4 1/5=21/5 since 4*5+1=21,
So 21/5*5/14=21/14 since the 5's cancel out,
simplify, you get 3/2.
Answer: 3/2.
