Answer:
Choice A
Step-by-step explanation:
There should be an open circle at 0 since there is no equals in the inequality
n is greater than zero so the line goes to the right.
Choice A
-2.54 is equal to -2 27/50
Answer:
a=-8/5
Step-by-step explanation:
(-1/2a-5)=3a+1
To find the opposite of 1/2 a−5, find the opposite of each term.
-1/2a-(-5)= -3a+1
The opposite of −5 is 5.
-1/2a+5=-3a+1
add 3a to both sides
-1/2a+5+3a=1
Combine-1/2and 3a to get 5/2a
5/2a+5=1
Subtract 5 from both side
5/2a=1-5
Subtract 5 from 1 to get −4.
5/2a=-4
Multiply both sides by 2/5 =0.4, the reciprocal of 5/2=2.5.
a=-4x(2/5)
express -4x(2/5)=1.6 as single fraction.
a= -4x2/5
Multiply −4 and 2 to get −8.
a=-8/5
Fraction −8/5 ≈−1.6 can be rewritten as −8/5 =−1.6 by extracting the negative sign.
a=-8/5
Answer:
$260
Step-by-step explanation:
Turn the percentage into a decimal.
35% -> 0.35
Multiply.
400 * 0.35 = 140
Subtract.
400 - 140 = $260
Best of Luck!
The function has three real zeros. The graph of the function intersects the x-axis at exactly three locations.
