Answer:
Step-by-step explanation:
1)
y = 5x-4 when x=5
y = 5*5-4
y = 25-4
y = 21
y = -2/5x + 3/8 when x = 1/3
y = -2/5 * 1/3 + 3/8
y = -2/15 + 3/8
y = -6/120
y = -1/20
y = 3x + 12 when x = 4
y = 3*4 + 12
y = 12 + 12
y = 24

ooh sorry bro but i can't understand. pls.. write it in english.. what subject is this???
Answer:
ET = 80/A^2
Step-by-step explanation:
First, isolate the variables that you need, which is E and T, using the two equations you were given.
EA = 8
E = 8/A (divide A on both sides to isolate E)
AT = 10
T = 10/A (divide A on both sides to isolate T)
Now, substitute.
ET --> (8/A) x (10/A) = 80/A^2
I'm pretty sure it's 3,000,000, "Basically, if the power is positive, you move the decimal point in the integer that many places to the right ex:
3.14 x 10 ^ 3 would be 3140.
If the power is negative, you move the decimal point to the left ex:
3.14 x 10 ^ -3 would be 0.000314" according to Yahoo
I belive the answer to your question would be -7a^2b^3
