kykrilka [37]4 years ago
4 0
Add 4x to both sides
0=-24x³+10x²+4x
factor out the -2x from everybody
0=-2x(12x²-5x-2)
factor
use ac method
12 times -2=-24
what 2 numbers multiply to get -24 and add to get -5?
-8 and 3
0=-2x(12x²+3x-8x-2)
0=-2x((12x²+3x)+(-8x-2))
0=-2x(3x(4x+1)-2(4x+1))
0=-2x(3x-2)(4x+1)
set each to zero
0=-2x
0=x

0=3x-2
2=3x
2/3=x

0=4x+1
-1=4x
-1/4=x

x=-1/4 or x=0 or x=2/3

Yasmin looked at the pattern 2, 16, 18, 54, and determined that the next number should be 162. What type of reasoning did she us
katrin [286]
The type of reasoning did Yasmine use is a deductive reasoning because it was not positive but confident. The deductive reasoning is a logical process in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true.

translate into an algebraic expression: 120 is increased by d % and increased by 25% . What is the result ?
frez [133]

The result is number r where:

r=(120+120\cdot\frac{d}{100})+(120+120\cdot\frac{d}{100})\cdot\frac{25}{100}

Hope this helps.

I need help ASAP PLEASE > How does the graph of f(x) = (x + 7)3 − 8 compare to the parent function g(x) = x3? (Please explain
marysya [2.9K]

Answer:

The graph has been moved 7 units to the left and 8 units down.

Step-by-step explanation:

When numbers are added directly to the "x" value, the graph shifts to the left. If negative numbers are added directly to the "x" value, the grap shifts to the right. Therefore, if there is a +7 directly altering the "x" value, the function shifts 7 units to the left.

When a number is added to the overall function, it shifts upwards. If this number is negative, the entire function shifts downwards. Therefore, if there is a -8 outside altering the function, then it has been shifted 8 units down.
