3 0

Answer:

Solutions will be unreal

Step-by-step explanation:

Given the quadratic equation ax^2+bx+c

The discriminant of the function determines its nature of its root

Discriminant D = b^2-4ac

If D <0, it shows that the roots of the equation will be a complex value. since D is less than 0 and the square root of a negative number does not exist. Hence, the solutions will be unreal

Answer:

38.5

Step-by-step explanation:

Lets say, first number = x



Second number = 3x+7



Total = 49




(x)+(3x+7)= 49



4x+7 = 49



4x = 42



x = 42/4



x= 10.5




x= 10.5



3x+7 = 3(10.5)+7 = 38.5

This one is a tough one. If you can explain it to me that’ll me great.
Crazy boy [7]

Answer:

C. 73 if I have read the given angle measurements correctly.

The angle measurements I see are:

219^\circ

(x-50)^\circ

(x+45)^\circ.

Step-by-step explanation:

Those angles together form a full rotation. A full rotation is equal to 360 degrees.

So we have the following equation to solve:

219+(x-50)+(x+45)=360

Combine like terms:

(x+x)+(219-50+45)=360

Simplify:

2x+(219-5)=360

2x+214=360

Divide both sides be 2:

x+107=180

Subtract 107 on both sides:

x=180-107

x=73
