In 1970 there were 160 African American women in elected public office in the United States. By 1993 the number had increased to

timama [110]

Answer:

Average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is 94.43.

Step-by-step explanation:

Here, according to the question:

Number of African American women in elected public office in the United States in the year 1970 = 160

Number of African American women in elected public office in the United States in the year 1993 = 2332

Now, the change in the number of elected women between 1970 & 1993

= Women elected in the year 1993 - Women elected in the year 1970

= 2332 - 160 = 2,172

or, the change in the number of elected women candidates between 1970 & 1993 is 2,172

Now, the difference in the time period is 1993 - 1970 = 23 years

So, $\textrm{The average rate of change} = \frac{\textrm{Total change in the quantity}}{\textrm{Time Interval}} \\=\frac{2172}{23} = 94.43$

Hence, the average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is 94.43.

Jackie has fewer than 20 h to work on her jewelry. It takes her half an hour to make a necklace and an hour to make a bracelet.

Virty [35]

X = necklaces, y = bracelets

at least twice as many bracelets as necklaces
y > = 2x <===
x > 0 <===

half hour for necklace, 1 hr for bracelet...fewer then 20 hrs
0.5x + y < 20 <==

What

Nataly_w [17]

I assume you want the equation to be solved, so this is a quadratic simultaneous equation.

y = x^2-x-3 ——— (1)
y = -3x+5 ——— (2)

Sub (1) into (2)
(This is the first three steps provided)

x^2-x-3 = -3x+5
0 = x^2+2x-8
0 = (x-2)(x+4) ——— (3)

Solve for x in (3):

x-2 = 0
x = 2

x+4 = 0
x = -4

Sub x into (2)

y = -3(2) + 5
y = -1

y = -3(-4) + 5
y = 17

Hence the solution sets are:

x=2, y=-1
x=-4, y=17
