Solve the system of linear equations.

4x - y = -9

3x - 3y = 0

x = -3

y = -3

Step-by-step explanation:

4x - y = -9 eqn 1

3x - 3y = 0 eqn 2

From eqn 1, make y the subject of the formula

4x - y = -9

4x + 9 = y

y = 4x + 9

Substitute y into the eqn 2

3x - 3y = 0

3x - 3(4x + 9) = 0

3x - 12x - 27 = 0

-9x - 27 = 0

-27 = 9x

-27/9 = 9x/9

-3 = x

x = -3

Substitute x into the eqn 1

4x - y = -9

4(-3) - y = -9

-12 - y = -9

-12 + 9 = y

y = -3

The values are

x = -3

y = -3

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
