Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
Answer:
x=8
Step-by-step explanation:
Draw it out.... 11x-4=3x+60
(add 4 to both sides)(subtract 3x from both sides)
8x=64
(divide 8 from 64)
x=8
If this is multiple choice im gonna say C
Answer:
(x+2)(x+5) or if you were looking for the x-intercepts they would be -5, and -2
Answer:
456 chairs
Step-by-step explanation:
If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42
If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414
Then you add up all the chairs, 456 chairs total.
