CAN ANYONE HELP ME WITH THIS ​

Mathematics
1 answer:
Alchen [17]3 years ago

The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.

The angle to the right of y is given as 48.

The three inside angles of a triangle need to equal 180.

So y  = 180 - 90 - 48 = 42 degrees.

If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8?
Eddi Din [679]

Answer:

2/3

Step-by-step explanation:

Y varies directly as x

Y =kx

Y=6 when x = 72

First find the relationship between y and x.

i.e find the value of k

Substitute the value of x and y

6 = k *72

Make k the subject of the formula

K = 6/72

K= 1/12

:. The rlationship between x and y is

Y = 1/12x

When x is 8

Y = 1/12 * 8

Y = 8/12

Y = 2/3 and that is the answer

Hope it helped you

How do you start this
lidiya [134]
You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that 
x^{2} - 4 [(x-4)^{2}] =16

expand, collect like terms, factor to find x, then plug x value back into original equation to find y

the distance around tims rectangulr book is 48 centimeters the length of each longer side is 14 cm what is the length of each sh
yanalaym [24]

let the length of each shorter side be x

length of longer side= x+14

2(x+14) + 2x = 48

2x + 28 + 2x = 48

4x + 28 = 48

4x = 48-28

4x = 20

x = 5

shorter side = 5cm
