Answer:
e= -1/2
Step-by-step explanation:
(4/3) +5/3 = (-6e - 5/3) +5/3
4/3 +5/3 = -6e
(3)/-6 = (-6e)/-6
e = -1/2
Answer:
Unit rate defined as the rates are expressed as a quantity of 1, such as 4 feet per second or 6 miles per hour, they are called unit rates.
As per the statement: Dan earns $ 384 over the course of a five-day week.
⇒Number of days = 5
Total cost earn by Dan = $384
Substitute the given values we have;
Therefore, $ 76.5 per day earned by dan
The answer is -94
hope this helps!
<span> first, write the equation of the parabola in the required form: </span>
<span>(y - k) = a·(x - h)² </span>
<span>Here, (h, k) is given as (-1, -16). </span>
<span>So you have: </span>
<span>(y + 16) = a · (x + 1)² </span>
<span>Unfortunately, a is not given. However, you do know one additional point on the parabola: (0, -15): </span>
<span>-15 + 16 = a· (0 + 1)² </span>
<span>.·. a = 1 </span>
<span>.·. the equation of the parabola in vertex form is </span>
<span>y + 16 = (x + 1)² </span>
<span>The x-intercepts are the values of x that make y = 0. So, let y = 0: </span>
<span>0 + 16 = (x + 1)² </span>
<span>16 = (x + 1)² </span>
<span>We are trying to solve for x, so take the square root of both sides - but be CAREFUL! </span>
<span>± 4 = x + 1 ...... remember both the positive and negative roots of 16...... </span>
<span>Solving for x: </span>
<span>x = -1 + 4, x = -1 - 4 </span>
<span>x = 3, x = -5. </span>
<span>Or, if you prefer, (3, 0), (-5, 0). </span>
Part A: To find the amount of the discount multiply the regular price by the amount of the discount:
80 x 20% = 80 x 0.20 = 16
The discount is $16
Part B:
20% off means she would be paying 80% of the original price ( 100% - 20% = 80%)
Multiply the regular price by 80%:
120 x 80% = 120 x 0.80 = 96
She will pay $96
