Select the solution(s) of log2x=1−log(x+4).
Answers
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1

does 9/20 and 18/30 form a proportion
Answers
Answer:
No, they don't.
Step-by-step explanation:
I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.
18 ÷ 9 = 2
30 ÷ 20 = 1.5
The quotients aren't the same. Same thing if you convert the fractions to decimals:
9 ÷ 20 = 0.45
18 ÷ 30 = 0.6
This means the two values do NOT form a proportion.
Hope this helps! Have a great day!
Answer:
No.
Step-by-step explanation:
9/20=18/30
9*30=20*18
120=360

Answer:
y = (3/-2)x + 4.
Step-by-step explanation:
slope intercept form is y = mx + b
1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.
2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).
3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.

Answer:
-4x-6x=-20=

-3(2x-3)=33=
x=-4
4x+3x+2x=180
x=20
Step-by-step explanation:
-4x-6x=-20
-4+(-6)=-10x
-10x=20 (divide both by 10)
x=-2 (divide by -1 to get positive)
x=2
-3(2x-3)=33
-6x+9=33
-9 . -9
-6x=24 (divide both by -6)
x=-4 (divide by -1 to make positive)
4x+3x+2x=180
(combine like terms)
9x=180 (divide both sides by 9)
x=20
