F(x)= -3x2^-3x, f(-2)

Mathematics
1 answer:
rjkz [21]3 years ago
7 0

Answer:

-6

Step-by-step explanation:

We know that the equation is f(x)=-3x^2-3x.

This means when we plug -2 in, the equation will be f(-2)=-3(-2)^2-3(-2). Simplify this to get -3(4)+6. Simplify this to get -12+6 which is equal to -6. Therefore, f(-2)=-6

******ANSWER ASAP PLEASE******
Lemur [1.5K]

(1/4)^-2 - (5^0 x 2) x 1^-1 =

(4/1)^2 - (1 x 2) x 1 = 16-2 = 14

If you raise something to the power of -2, swap numerator and denominator and remove the minus.

So (1/4)^-2 = 4^2 = 16

Also 1^-1 is just 1, not -1.

The equation for determine the cost of sandwiches one afternoon is <span>y<span>=5.95*x 
</span></span> <span>x= number of sandwiches</span>
<span>5.95 = cost one sandwiches</span>

The equation for determine the number of sandwiches sold one afternoon is <span>x=y/5.95</span>

We have that

<span>y=71.40</span>
<span>x=(71.40/5.95)   x=12 </span> <span>the response is 12 <span>sandwiches sold one afternoon</span></span>

Which graph represents the function f(x) = (x – 3)^2?
Natasha_Volkova [10]

Answer:

Step-by-step explanation:

Please, share the possible answer choices next time.

The graph of a parabola y = x^2 has its vertex at the origin, (0, 0), and opens up.  By replacing x with (x - 3), we translate the graph 3 units to the right.

Equation of the line that passes through points (-4,8) and (1,3)
Delvig [45]

Answer:

y=-x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-8)/(1-(-4))

m=-5/(1+4)

m=-5/5

m=-1

y-y1=m(x-x1)

y-8=-1(x-(-4))

y-8=-(x+4)

y-8=-x-4

y=-x-4+8

y=-x+4
