Answer:
Decrease by 3.9%
Step-by-step explanation:
54,500(1-x) = 52355
x=0.03935... = 3.935% or 3.9%
Answer:
b. y = -7x + 4
1. y = -7(-5)+ 4 = 35+4= 39
2. -24= -7x + 4
-28 = -7x
4 = x
3. y = -7(0)+4= 4
4. 0 = -7x+4
-4= -7x
4/7 = x
c. 3y - 5x = 15
1. 3y - 5(6)
3y-30=15
3y=45
y = 15
2. 3(-10)-5x=15
-30-5x=15
-5x = 45
x = -9
3. 3y-5(0)=15
3y=15
y=5
4. 3(0)-5x=15
0-5x=15
-5x=15
x=-3
Step-by-step explanation:
Answer:
let the number be x
(5x-3) + (x+9)=24
6x +6= 24
6x=18
x=3
The number is 3
Step-by-step explanation:
Answer: x = 28
Step-by-step explanation:
x + 20=3x-36
20=2x-36
56=2x
56/2=28
So 28= x
Answer:
N/A, y is NOT a real number.
Explanation:
<em> To solve for y, you would have to take the square root of both sides of the equation</em>
<em>if one of the sides is a negative number (which is the case currently), there is no solution.</em>
<em>If -64 was positive, then y could be solved for, but as it is negative, that is not possible.</em>
