Answer:
1) (x + 4)(x - ½) = 0
4x² + 16x = 0
2) 0.25x² + 0.8x - 8 = 0
3x² - 4x = 15
Step-by-step explanation:
1) (x + 4)(x - ½) = 0
x = -4, ½
4x² + 16x = 0
4x(x + 4) = 0
x = 0, -4
2) (x - 6)(x + 9) = 0
x = 6, -9
(x - 1)² = 4
(x - 1)² - (2)² = 0
(x - 1 - 2)(x - 1 + 2) = 0
(x - 3)(x + 1) = 0
x = 3, -1
These two are easier to solve using product = 0 property, while the other two would be easier using the quadratic formula
You can then write really big numbers without running out of space
for example instead of 2300000000000000000000000000
you can just write 2.3 x 10^27
Answer:
h=2
Step-by-step explanation:
f is translated right 2 units (so h=2) and up 2 units (so k=2)
3/5q = 1 Given
(3/5) 3/5q = 1(3/5) Multiply each side by 3/5 (Mult. Prop. of Equal)
q = 3/5 Simplify
Answer: 23498.935
Step-by-step explanation:
this helped me in middle school so please remember this equation
A=P(1+R/N)NT
A=AMOUNT
P=PRINCIPAL
R=INTEREST RATE
N=NUMBERS OF TIMES THE INTEREST IS COMPOUNDED
NT=TIME(YEARS
So now we have this... right...
A=P(1+R/N)NT
you have to fill it in and you will get
a=22,150(1+3/1)^2
put that in your handy dandy calculator and you will get your answer
