A quadratic equation is an equation that includes a squared term. For example, 3x + 7 = 28 is not a quadratic equation as it only has x, whereas x^2 + 5x + 6 = 0 is a quadratic equation as it includes x^2. Quadratic equations also usually have two solutions, whereas linear equations (like my first example) only have one.
I hope this helps! Let me know if you would like me to explain anything more :)
Answer:
1 sandal= $7
1 flip flop =$2.5
Step-by-step explanation:
say one sandal costs x and one flip flop costs y
3 x+y=23.50
4x+2y=33
solve using simultaneous equationsto find the values of x and y
60 tables total. 25% of those seat 22 people. 60 X 25% = 15. So 15 of the tables seat 22 people.
The remaining tables (60 tables - 15 tables = 45 tables) seat 44 people.
So you have:
(15 tables X 22 seats) + (45 tables X 44 seats) = total seats.
2310 TOTAL seats.
The slope is the number next to the variable and the y intercept is the number after the slope.
#1. Slope= -3
Y-intercept=-3
#2. Slope=5/2
Y-intercept=-4
#3. Slope=1/3
Y-intercept=3
#4. Slope=-2
Y-intercept=2
#5. Slope=-2/5
Y-intercept=-2
#6. Slope=-2/3
Y-intercept=-2
Hello!
If Kong took a 85 second and we if Nolan took 15 slower then Nolan took a 72.25 second test. First you would find 14 percent of 85 then that is 12.75. Minus that from 85 and you get 72.25.
Hope It helps!
