7(5x + 9) = 12 - (x +9)
den301095 [7]

Answer:

\frac{-5}{3} is the answer

Step-by-step explanation:

7(5x+9)=12+−1(x+9)(Distribute the Negative Sign)

7(5x+9)=12+−x+−9

(7)(5x)+(7)(9)=12+−x+−9(Distribute)

35x+63=12+−x+−9

35x+63=(−x)+(12+−9)(Combine Like Terms)

35x+63=−x+3

Add x to both sides.

35x+63+x=−x+3+x

36x+63=3

subtract 63 from both sides.

36x+63−63=3−63

36x=−60

Divide both sides by 36.

\frac{36x}{36} =\frac{-60}{36}\\

-5/3 is the answer.

ik this doesnt make any sense but hope this helps

Write the expression as a monomial in its standard form.<br><br> 9/16p^7 ⋅ (-4/3p^4)
Aleksandr-060686 [28]

Answer:

-3/4 p^11

Step-by-step explanation:

9/16p^7 ⋅ (-4/3p^4)

Multiply the numbers together

9/16 * -4/3 = -3/4

Now multiply the variables

p^7 * p^4

We know that a^b* a^c = a^(b+c)

p^(7+4) = p^11

Putting these back together

-3/4 p^11

Find the vertex, zero(s), and y-intercept of the graph of y = –x2 + 4x + 32.
xxMikexx [17]

Answer:

The correct option is A.

Step-by-step explanation:

The given equation is

y=-x^2+4x+32

Put x=0, in the given equation.

y=-(0)^2+4(0)+32=32

The y-intercept is (0,32).

Put y=0, to find the x-intercept.

0=-x^2+4x+32

0=-x^2+8x-4x+32

0=-x(x-8)-4(x-8)

0=-(x+4)(x-8)

x=-4,8

Therefore the y-intercepts are (-4,0) and (8,0).

The vertex of a parabola f(x)=ax^2+bx+c is

(-\frac{b}{2a},f(-\frac{b}{2a}))

-\frac{b}{2a}=-\frac{4}{2(-1)}=2

Put x=2 in the given function.

y=-(2)^2+4(2)+32

y=-4+8+32

y=36

The vertex is (2,36).

Therefore option A is correct.
