Vitek1552 [10]3 years ago
7 0

Answer:

B

Step-by-step explanation:

-x - 1 = x^2 + x

x^2 + 2x + 1 = 0

(x+1)(x+1) = 0

x = -1 (double soution)

y = 1-1 =

y =0

A cake recipe suggests a cooking temperature of 325 degree Fahrenheit if the batter is less than one inch thick and 350F if the
bija089 [108]
The first step is finding the height of the cake. The formula for the volume of a box: Volume= length x width x height. So given the volume and length and width: 100= 9 x 11 x h. 100=99h and solve for h. h= 1.01 inches so the batter is more than one inch thick. That means that the matter needs to be baked at 350 degrees Fahrenheit. The formula to convert from Fahrenheit to Celsius:  T(C)= (T(F)-32) x (5/9). So (350-32) x (5/9) = 176.667. Rounded to the nearest whole number is 177 degrees celsius.

An adult African elephant weighs 8.25 tons. How much do 27 elephants weigh?
ohaa [14]

I do believe that you would multiply the number of elephants by how much one weighs on average.. That would mean 8.25x27 which would equal 222.75

For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = one-half?
likoan [24]

Answer:

V=16

Step-by-step explanation:

We are given that an inverse variation

p=\frac{8}{V}

We have to find the value of V when p=1/2

To find the value of V we will substitute the value of p

Substitute the value of p

Then, we get

\frac{1}{2}=\frac{8}{V}

\frac{V}{2}=8

Using multiplication property of equality

V=8\times 2

Using multiplication property of equality

V=16

Hence, the value of V=16

F(x)= -x-2, g(x)=x^2, what is (g°f)(-6)
Katena32 [7]
<span>f(x) = -x - 2
</span><span>g(x) = x^2

</span><span>(g°f)(-6) = ?

First, we find f(-6)
</span>f(x) = -x - 2
f(-6) = -(-6) - 2
f(-6) = 6 - 2
f(-6) = 4

Since f(-6) = 4,
(g°f)(-6) = g(4)

g(x) = x^2
g(4) = 4^2
g(4) = 16

Therefore, (g°f)(-6) = 16
