Slope = 2/5 and the point is (10,3)
The form of the equation is y = mx +b where m is the slope and b is the y-intercept.
To find the y-intercept (b) replace y, m and x with the given information:
y = 3 x = 10 and m = 2/5
Now you have 3 = 2/5(10) +b
Solve for b:
3 = 4 + b
Subtract 4 from each side:
b = 3-4
b = -1
Now replace b in the equation to get:
y = 2/5x-1
The trick here is that both times, part of the weight is soup
and part of the weight is the empty metal can.
1/2 soup + MTcan = 5
1/3 soup + MTcan = 4
Before going any further, it will make it a lot easier later if we change
the fractions in both equations to a common denominator:
1/2 = 3/6
1/3 = 2/6
3/6 soup + 1 MTcan = 5
2/6 soup + 1 MTcan = 4
Subtract the 2nd equation from the 1st one:
1/6 soup = 1
Multiply each side by 6 : <u>1 soup = 6</u>
Substitute this in the first equation:
1/2 soup + 1 MTcan = 5
1/2 ( 6 ) + 1 MTcan = 5
3 + 1 MTcan = 5
Subtract 3 from each side: <u>1 MTcan = 2</u>
The empty can weighs 2.
All the soup it can hold weighs 6.
A full can of soup weighs (2 + 6) = <em><u>8</u></em>
Answer:
Frue
Step-by-step explanation:
Answer:
1, 8, 5, 1, 2, 4, 0, 7, 9, 9
Step-by-step explanation:
no matter how much is in power to 1 is always 1
(8×8)/8
= 8^(2-1)
= 8
3x =15
x = 15/3
= 5
(5×6) ÷ ( 10 × 3)
= 30/ 30
= 1
no matter something having power 1 is same
-5 +9
= 9- 5
= 4
zero dividend by something is always zero
but remember something divided by zero is infinitely
4x - 9 = 2x + 5
= 2x = 14
= x = 7
99/11 = 9
15 - x = 6
= x = 15 - 6
= 9
