NEED HELP!!!
AnnyKZ [126]

Answer:

see explanation

Step-by-step explanation:

(1)

\frac{6}{2} = \frac{4}{p} ( cross- multiply )

6p = 8 ( divide both sides by 6 )

p = \frac{8}{6} = \frac{4}{3}

(2)

\frac{n}{4} = \frac{8}{7} ( cross- multiply )

7n = 32 ( divide both sides by 7 )

n = \frac{32}{7}

(3)

\frac{5}{3} = \frac{x}{4} ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = \frac{20}{3}

For a quadratic function ƒ(x)=ax2+bx+c, ƒ(−1)&lt;1, ƒ(1)&gt;−1, and ƒ(3)&lt;−4. What could be the sign of a?
denis23 [38]

Answer:

"a" must be negative

Step-by-step explanation:

The slope between points (-1, 1) and (1, -1) is a minimum of (-1-1)/(1-(-1)) = -1.

The slope between points (1, -1 and (3, -4) is a maximum of (-4-(-1))/(3-1) = -3/2.

Thus, as x increases, the slope is decreasing. In order for that to be the case, the value of <em>a</em> must satisfy a < 0.
