Two complementary angles have measures of s and t. if t is less than twice s, which system of linear equations can be used to determine the measure of each angle?

Two complementary angles have measures of s and t. if t is less than twice. The system of a linear equation that can be used to determine the measure of each angle is called substitution.

A system of linear equations is the arrangement of one or more similar equations involving the same variables.

From the given information;

Now;

We know that a complementary angle is an angle that the addition of the angles is equal to 90°

s + t = 90

Therefore, we can conclude that the system of a linear equation that can be used to determine the measure of each angle is called substitution.

angle 1 (s):

angle 2 (t): t < 2s  

s + t = 90

t < 2s

You didn't provide the choices so hopefully you can figure it out with the information I provided.

Note: "t" must be less than 30

step-by-step explanation:

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
