Answer:

a=2

Step-by-step explanation:

Please see attached picture for full solution.

Method 1: Substitute x with another number, other than the numbers that you have already tried. Zero is a good number to work with :)

Then, subst. the values of b and c which you have already found into the equation. Then simplify to arrive at your answer.

Method 2: Notice that when you expand the right hand side, only a(x)({x}^{2}) can give you a x^{3}term. Hence, compare the coefficients of {x}^{3} on both sides. This method is quite safe since the value of a won't be affected in case the value of b and c is wrong.

What is y > 2x - 4 and 6x +3y < 9​
fgiga [73]

you can make a table of values using any intergers and as many as you need in this case I chose 0,1,2 then you replace them in your actual equation and find the values of y.finally plot.

after plotting the points you shade the unwanted region(the sign will direct you) in this case the wanted region is y>.so you shade the less than area.

for the second one you make the equation simpler

6x+3y<9

3y<-6x+9

and also make a table of values,replace were there's x and plot

I hope this helps!

x axis is x = 4.00 - 7.00t2, with x in meters and t in seconds. (a) At what time and (b) where does the particle (momentarily) s
andrezito [222]

Answer:

(a) 0 s

(b) 4.00 m

(c) -0.76 s

(d) +0.76 s

Step-by-step explanation:

x=4.00-7.00t^2

It stops momentarily when the velocity, v is 0. v is the derivate of x.

(a) v=\frac{dx}{dt}=-14.00t

Setting this to 0,

-14.00t=0

t=0

(b) Substitute this value for t in x to get its position.

x=4.00-7.00\times0^2=4.00 m

It passes the origin when x=0

4.00-7.00t^2=0

7.00t^2=4

t^2=\frac{4}{7}

t=\pm\sqrt{\frac{4}{7}}

(c) The negative time is t=-\sqrt{\frac{4}{7}} =-0.76 s

(d) The positive time is t=+\sqrt{\frac{4}{7}} =+0.76 s

When multiply 2 numbers raised to a power,

Just all the  two exponents

Waht is the x^2 + 10 = 0
NARA [144]

Answer:

x = ±√10i (i outside the radical), or approximately ±3.62i, or no solution depending on your class.

Step-by-step explanation:

x^2 + 10 = 0

x^2 = -10

x = ±√-10

x = ±√10i (i outside the radical), or approximately ±3.62i.

The solution is not real.

If you meant x^2 - 10 = 0 then x = ±√10 or approximately ±3.62. This solution is real.
