Y=6. you would replace x with 7 in the equation.
6(7) = 7y
42=7y

PLEASE HELP
Vlada [557]

Answer:

The equation is y = x + 9.

Step-by-step explanation:

We need to equation of SR

Slope = slope of UV = 3/2

= 1.

One point on SR is (-2, 7) so using the point-slope form of the equation:

y - y1 = m(x - x1)

Here m = 1, x1 = -2, y1 = 7:

y - 7 = 1(x - (-2))

y - 7 = x + 2

y = x + 9

Find a polynomial function with leading coefficient 1 that has the given zeros, multiplicities, and degree. zero: 1, multiplicit
vfiekz [6]

Polynomial expression for the given  conditions is formulated in the equation

y(x)=1*(x-2)^3(x-0)^2

The polynomial for the conditions with leading coefficient 1 that has the given zeros, multiplicities, and degree. Zero: 2, multiplicity: 3 Zero: 0, multiplicity: 2 Degree: 5 is given as

According to the given condition

The given conditions to write the polynomial equations are as follows

Zero 2  and Multiplicity 3

Zero 0 and Multiplicity 2  

Degree of polynomial expression  = 5

The leading coefficient of polynomial expression = 1

Let us consider the polynomial equation has only one variable and hence in the general form we can write the equation of polynomial as follows

From the general form of polynomial expression as shown in equation (1) we can write

Polynomial expression for the given  conditions is formulated in the equation

y(x)=1*(x-2)^3(x)^2-------(2)

So the polynomial for the conditions given in the question is expressed as

y(x)=1*(x-2)^3(x)^2

If mZDEC = (12x - 3), mZBCE =
kati45 [8]

Answer:

Step-by-step explanation:

12x - 3 = 180 - (7x - 26) supplementary angles

19x = 209

   x = 11

m∠DEC = 12(11) - 3 = 129°

m∠BCE = 7(11) - 26 = 51°

M∠ADE = 129 - 72 = 57°  exterior angle rule

m∠EDB = 180 - 57 = 123° supplementary angles

m∠DBC = 57° corresponding angle to ADE

the gravitational attraction between two masses varies inversely as the square of the distance between them. if the attraction f
Marat540 [252]

Answer:

  33 1/3 lb

Step-by-step explanation:

When the distance between them goes from 8 ft to 12 ft, it is 1.5 times what it was. Then the force will be multiplied by the inverse of the square of this:

  (75 lb)×1/(1.5²) = 75/2.25 lb = 33 1/3 lb

At 12 feet apart, the attraction force is 33 1/3 pounds.

Y = –2x + 30<br> y = 4x<br> Plz help
kati45 [8]

Answer: x=5

Step-by-step explanation:

Step 1:-

Given equations are y=-2 x+30........(1)

   another equation is y=4 x ..........(2)

Step 2:-

solving these two equations (1) and (2)

Equating both equations are  4 x = -2 x+30

4 x+2 x =30

6 x =30

Step 3:-

The final answer is x=5
