Answer:
-0.5 or -2/9
Step-by-step explanation:
(-2x-1)(9x+2)
<em>o</em><em>p</em><em>e</em><em>n</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>b</em><em>r</em><em>a</em><em>c</em><em>k</em><em>e</em><em>t</em>
-18x² - 4x - 9x - 2
-18x²-13x-2
(18x²+9x)(+4x+2)
<em>f</em><em>a</em><em>c</em><em>t</em><em>o</em><em>r</em><em>i</em><em>s</em><em>e</em>
9x(2x+1) +2(2x+1)
(9x+2)(2x+1)
:<em>separate</em><em> </em><em>the</em><em> </em><em>bracket</em><em> </em><em>and</em><em> </em><em>equate</em><em> </em><em>to</em><em> </em><em>0</em>
9x+2=0
<em>collect</em><em> </em><em>like</em><em> </em><em>terms</em>
9x= -2
<em>divide</em><em> </em><em>through</em><em> </em><em>by</em><em> </em><em>9</em>
x= -2/9
or
4x = -2
<em>divide</em><em> </em><em>through</em><em> </em><em>by</em><em> </em><em>4</em>
<em>x</em><em> </em><em>=</em><em> </em><em>-</em><em>2</em><em>/</em><em>4</em>
<em>:</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-</em><em>0</em><em>.</em><em>5</em>
<em>answer</em><em> </em><em>=</em><em> </em><em>-</em><em>0</em><em>.</em><em>5</em><em> </em><em>or</em><em> </em><em>-</em><em>2</em><em>/</em><em>9</em>
Answer: A) Domain: All real numbers , Range: All real numbers
Step-by-step explanation: Since the line of the graph continued to infinity, the answer for both domain (goes from Left to right) and range (goes up to down) would be all real numbers
Answer:
There are 8 more girls
Step-by-step explanation:
If you divide 32 by 8 (since the ratio is 3:5 which is 8 parts (3+5)). You get 4.
Thus, there are 12 boys and 20 because 3*4 is 12 and 5*4 is 20. 12+20 is 32.
Answer:
Line A equation = y=-9/8x+69/4
Line B equation = y=-10/9x+131/9
Step-by-step explanation:
#13 is 3000 because since each T-shirt is $650 and they buy 4 you multiply and get $2600 and since she received 400 dollar change then you add that value to the total cost and get 3000 that means she paid 3000
#14 is a millennium
1 year is 365 days
1 decade is 10 years
1 century is 100 years
1 millennium is 1000 years
So it has to be 1 millennium since 1000 years is the most out of the others
