A quadratic equation is an equation with exponents and x's, for example 3x^2+4x+3 is a quadratic. and quadratics usually have two points it can cross the x axis. though that doesn't mean it always crosses twice. some quadratic equations can cross more then twice and some don't at all.
linear equations are simple. they always show a straight line on a graph.
And exponential are kind like quadratics, exponential always have an exponent but don't have multiple x intercepts. exponentials are equations like the equation for compound interest rates (Initial Account Balance * (Interest Rates) ^ Time) it is exponentially growing using exponents.
Divide 4.2 by 30 and you get $0.14 per pen
Answer:
45 students
Step-by-step explanation:
To find how many students don't prefer soccer, we have to take 90% of 50. This is because 10% of the 50 students like soccer, so the percentage that don't like it is 100-10=90%. 90% of 50 = 0.9*50 = 45 students.
Answer:
1/2 There you go
Step-by-step explanation:
Answer: -4,-2
Step-by-step explanation: Since it is reflected across the x- axis, translated two units left and six units down it would be -4, -2 because 2-6= -4
