Answer:

Answer:

y=-1/12x+11/3

Step-by-step explanation:

When a line is perpendicular, the slope is going to be the negative reciprocal

negative reciprocal ex: 3----> -1/3

since the slope of line you are given is 12, the slope of the perpendicular line is -1/12

so you now know your equation so far is y= -1/12x+b

to find b, replace x and y with the coordinates.

4= -1/12(-4)+b

4=1/3+b

11/3=b

the equation is y=-1/12x+11/3

Plz help meeeeeeeeeee
PSYCHO15rus [73]

Answer:

Please check the explanation.

Step-by-step explanation:

We know the equation

y = kx

k = y/x

where k is the proportionality constant

so,

First ratio can be calculated as

Miles = 45

Hours = 3/4

The ratio = 45 / (3/4)

                = (45 × 4) / 3

                = 180/3

                = 60

Thus, the proportionality constant = 60

Thus, the remaining ratios can be calculated as:

The Pair (135, Hours)

135/Hours = 60

Hours = 135 / 60

           = 27/12

           = 9/4

           = 2.25

Thus, the pair is (135, 2.25)

The Pair (Miles, 3)

Miles/3 = 60

Miles = 60×3

         = 180

The Pair (90, Hours)

90/Hours = 60

Hours = 90 / 60

          = 3/2

          = 1.5

Thus, the complete table:

Miles           45           135           180             90

Hours           3/4          9/4           3                 3/2

Verification:

Miles / Hour =  45/(3/4) = 60

Miles / Hour = 135 / 2.25 =  60

Miles / Hour = 180 / 3 = 60

Miles / Hour  = 90 / 1.5 =  60

Find the value of c so that the polynomial p is divisible by (x+2)
alexandr1967 [171]

Answer:

The value of c is 8.

Step-by-step explanation:

When a function is divisible by a factor, it will get 0 value. So, you have to substitute x = -2 into p(x) and equals to 0 :

p(x) = 4 {x}^{3}  + c {x}^{2}  + x + 2

p( - 2) = 4 {( - 2)}^{3}  + c {( - 2)}^{2}  + ( - 2) + 2

4( - 8) + 4c - 2 + 2 = 0

- 32 + 4c = 0

4c = 32

c = 32 \div 4

c = 8

2x - 5y = 16<br> x - 2y = 5<br> elimination?
harina [27]

Answer:

Y = 6

X = 24

Step-by-step explanation:

2x -5y = 16

(x -2y =5)*2

_______________

2x -5y = 16

2x - 4y = 10

_______________

(2x -5y = 16) - (2x - 4y = 10)

_______________

0x -y = 6

_______________

y =6

_______________

Replacing in equation 1:

2x - 5(6) = 16

so, 2x = 16 + 30

2x = 48

x = 24
