Is y=7-3x linear or non linear
sveta [45]

Answer:

It is linear

Step-by-step explanation:

If you graphed it it would be in a strait line. You also want to make sure that you write your answer in slope intercept form (y = mx + b). Your line would have to be y = -3x + 7 to be in slope intercept form.

C=-14
First you divide -6 by -3 and since the signs are the same it is a positive number. the answer is 2. that makes it c-2=-16. Then you add the inverse of -2, so 2, to both sides. This makes it c=-14

The total rainfall in forks , washington, october was 8 3/8 in. in september ,60% less rainfall fell in October
iren2701 [21]
Rainfall in October in Forks, Washington = 8 3/8 inches
                                                                 = 67/8 inches
Percentage of rainfall that has fallen less in September in Forks, Washington = 60%
Let us assume the amount of rainfall in September in Forks, Washington = x
Then
100x/60 = 67/8
10x/6 = 67/8
5x/3 = 67/8
5x * 8 = 67 * 3
40x = 201
x = 201/40
   = 5 1/40 inches
So the amount of rainfall in September in Washinton is 5 1/40 inches.

marlee spins a spinner and rolls 1-6 # cube. the spinner has 5 equal parts # 1-5 . what is the probability she will spin an even
forsale [732]
The events are independant (i.e. what she rolls on the cube has no impact on how the spinner works). The probability of two independant events is given by: 

P_t = P_{cube} \times P_{spin}

For the cube, 1/2 the numbers meet our requitment of being even, so:
P_{cube} = \frac{Desired}{Total} = \frac{even}{total} = \frac{3}{6} =\frac{1}{2}

For the spinner, there are 3 odds out of 5 (1, 3 & 5) so:
P_{spin} =\frac{Desired}{Total} = \frac{odd}{total} = \frac{3}{5}

and then:
P_T = P_{cube} \times P_{spin}
P_T =\frac{1}{2} \times \frac{3}{5}
P_T =\frac{3}{10}
