Answer:
Graph y=2x-7. Use the slope-intercept form to find the slope ... where is the slope and is the y-intercept. Find the values of and using the form . The slope of the line is the value of , and the y-intercept is the ... y-intercept: Any line can be graphed using two points. Select two values, and plug them into the equation to
Step-by-step explanation:
The constant of proportionality is <em>4 .</em>
The equation is [ <em>Height = (4) times (Days)</em> ] .
When the sunflower is 60cm tall, 60 = (4) times (Days).
Divide each side of the equation by 4: <em>15 = Days</em>
Yes x=-2. You are doing great! Keep it up! Mark as brainliest! :)
Answer:
<em>The cost of a gallon of milk changed 31%</em>
Step-by-step explanation:
<u>Percent Change</u>
Is the difference between two values of the same variable in different times or conditions, expressed as a percentage of the original value.
The formula is:
Where
v1 = original value
v2 = final value
The gallon of milk cost v1=$2.90 in 2002 and v2=$3.80 in 2018. The percent change is:
Pc = 31%
The cost of a gallon of milk changed 31%
Answer:
b(x) = 1,000 * 2.15^x
Step-by-step explanation:
1,000 represents the intial colony size. An increase of 115% correlates to multiplying the said size by 2.15 to the power of the hours elapsed.
Common error: The factor is 2.15 and not 1.15 as an increase of 100% is doubling the amount. i.e. if the increase was 15%, we would multiply by 1.15.
