Answer:
a=-9 b=-5
Step-by-step explanation:
a(3-x) = - 2x+b
a3 - ax = - 2x+b
a3 - 2a = - 4+b
If you take a=-9
-27+18=-4+b
b= -5
Answer:
the standard form of equation is in the form of
x - 9y = -45 , so the answer is B
What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.
{-5, 8} is the list of factors of -40 that add up to 3.
Answer:
length = 11 ft, width = 6 ft
Step-by-step explanation:
Let w be the width, l be the length and p the perimeter. You can write down the following equations:
1. w = l - 5
2. p = 2*(w + l)
Now you have two equations with two unknown.
Plugging eq.1 in eq.2:
p = 2*(l-5 + l)
p = 2*(2*l - 5)
p = 4*l - 10
Remember p = 34
34 = 4*l - 10
4*l = 44
l = 11
Using eq.1 to solve for w:
w = 11 - 5
w = 6
