Direct variation model: y = kx, where k is the constant of proportionality.

Only (d) satisfies this definition. There must be no offset of the straight line graph away from the origin (0,0).

What is the solution to the following system of equations?

fenix001 [56]

Answer: (5,0)

Step-by-step explanation:

x - 3y =5 -----------(1)

2x + y = 10 ----------(2)

By elimination method, multiply eqn(1) by 2

2x - 6y = 10 ------------(3)

eqn(3) - eqn(2)

-7y = 0

Divide bothside by -7

y= 0

Now, we substitute the value of y in eqn(1)

x - 3(0) = 5

x - 0 = 5

x=5

Therefore,x=5 and y=0

A ramp is being built and attached to a building to help with deliveries. The angle that the bottom of the ramp makes with the g

Kruka [31]

Answer: The measure of the other acute angle is 52.8°

Step-by-step explanation:

Hi, since the situation described forms a right triangle ( see attachment) , we know that the three interior angles of a right triangle add up to 180 degrees.

The value of one angle is given = 37.2°.

Since is a right angle it has also a right angle of 90°.

So we can write an equation:

x + 37.2 + 90 = 180

Where x is the measure of the other acute angle.

Solving for x:

x = 180-90-37.2

x = 52.8°
