Answer: 0.0008 M
Step-by-step explanation: 10^-pH
10^-3.1 = 0.0008
Answer:
rectangular; 32 in²
Step-by-step explanation:
The base is rectangular, because 1 set of sides is longer than the other.
To find the area of the base, multiply 4 by 8 to get 32 in².
Answer:
2
Step-by-step explanation:
1. "the sum of -4x and 2 is 9"? -4x + 2 = 9
Answer:
A.-4x + 2 = 9
2. solve x - 6 = -18
x = -18 +6
x = -12
Answer is B.x = -12
3. solve 4x + 3 = 47
4x = 47 -3
4x = 44
x = 44/44 = 11
Answer is A.x = 11
4. solve 1/3x = 12
x= 12 / (1/3)
x = 12 * 3 = 36
Answer is C.x = 36
5. solve 3x + 3 = 21
3x = 21 -3
3x = 18
x = 18/3 = 6
Answer is B.x = 6
6. solve. 3/2x - 4 = 16
3/2x = 16 + 4
3/2x =20
x = 20 / (3/2)
x = 20 * 2/3
x = 40/3
A.x = 13 1/3
Answer is B.x = 13 1/3
Answer:
Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)
Step-by-step explanation:
m=3 , x1=1 , y=-3
y-(-3)=3(x-1)
y+3=3x-3 subtract 3 from both sides
y=3x-6 the answer in the slope-intercept form y=mx+b
