Step-by-step explanation:
<u>Use the slope formula:</u>
m = the slope.
<u>Substitute the values into the formula:</u>
<u>Solve:</u>
<u>Simplify 16/4:</u>
Plug in 3 for f(x)
f(3)=(3)²+7
f(3)=9+7
f(3)=16
Hoped this helped!
Answer:
x = 53
Step-by-step explanation:
angle 3 + angle 8 = 180 because of linear pair
66 + 2x + 8 = 180
74 + 2x = 180
2x = 180 - 74
2x = 106
x = 106/2
x = 53
Answer:
6. 19 candles
7. 6 pills
Step-by-step explanation:
6. If a particular candle burns for 2 3/4 hours (=2.75) and you want to use similar candles to burn one at a time over 10 days for 5 hours each day, find the total number of hours: 10 x 5 = 50 hours. Then, divide by the amount of time it takes for one candle to burn: 10÷2.75 = 18.18. Since the answer is a decimal, you will need to round to the next whole number = 19 candles.
7. Given the rules that no more than three pills may be taken in a four-hour period and each pill must be taken 1 1/2 hours (=1.5) apart, you can take the total number of hours (10) and divide by the time between each pill (1.5):
10 ÷ 1.5 = 6.7
Since you won't take part of a pill, the most you can take is 6 and because the intervals are 1.5 hours, 1.5 + 1.5 + 1.5 = 4.5, you will not have taken more than 3 in any four hour period.
Answer:
a=39/7 or 5.57
Step-by-step explanation:
7a=39
Divide both sides by 7
