Answer:

80 Degrees

Solve this quadratic equation using the quadratic formula.<br> 5 - 10x - 3x2 = 0
Olegator [25]

-3x^2 - 10x + 5 = 0

Quadratic formula:

-b +/- sqrt[b^2 - 4(a)(c)]/2(a)

So. . . 10 +/- sqrt[(10^2) - 4(-3)(5)]/2(-3)

10 +/- sqrt[100+60]/ -6

10 +/- sqrt[160]/-6

At a cost restaurant the cost for a hot dog and a soft drink is $2.10. The cost for two hot dogs and three soft drinks is $5.15.
Alja [10]

Answer:

The cost of soft drink is $0.95

Step-by-step explanation:

Let the cost of hot dog be x

Cost of 2 hot dogs = 2x

Let the cost of soft drink be y

Cost of 3 soft drinks = 3y

At a cost restaurant the cost for a hot dog and a soft drink is $2.10.

So, x+y=2.10

The cost for two hot dogs and three soft drinks is $5.15

So, 2x+3y=5.15

Plot the lines on the graph:

x+y=2.10 --Purple line

2x+3y=5.15 --- Black Line

Intersection point =(x,y)=(1.15,0.95)

Hence The cost of soft drink is $0.95
