The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to

Maksim231197 [3]

Considering the given function, we have that:

a) D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.

b) D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.

<h3>What is the function in this problem?</h3>

The distance that the family is from home, after t hours of driving, is given by:

D(t) = 3260 - 55t.

Then, after 12 hours, the distance is given by D(12), that is:

D(12) = 3260 - 55 x 12 = 2600.

D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.

D(t)=2490, hence:

3260 - 55t = 2490

55t = 770

t = 770/55

t = 14

D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.

Help me with this question

Molodets [167]

Answer:

Pretty sure its 7.5 units²

Step-by-step explanation:

5·3=15÷2=7.5

Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.

For example: base=3, height=7. With rectangles it would be 21 units².

But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²

5/6h - 7/12 = -3/4h - 13/6

vovangra [49]

$\frac{5}{6} h$ - $\frac{7}{12}$ = $-\frac{3}{4} h$ - $\frac{13}{6}$

First, simplify $\frac{5}{6} h$ to $\frac{5h}{6}$ / Your problem should look like: $\frac{5h}{6}$ - $\frac{7}{12}$ = $-\frac{3}{4} h$ - $\frac{13}{6}$
Second, simplify $\frac{3}{4} h$ to $\frac{3h}{4}$ / Your problem should look like: $\frac{5h}{6}$ - $\frac{7}{12}$ = $- \frac{3h}{4}$ - $\frac{13}{6}$
Third, multiply both sides by 12, which is the LCM of 6 and 4. / Your problem should look like: 10h - 7 = -9h - 26
Fourth, add 9h to both sides. / Your problem should look like: 10h - 7 + 9h = -26
Fifth, simplify 10h - 7 + 9h to 19h - 7 / Your problem should look like: 19h - 7 = -26
Sixth, add 7 to both sides. / Your problem should look like: 19h = -26 + 7
Seventh, simplify -26 + 7 to -19. / Your problem should look like: 19h = -19
Eighth, divide both sides by 19. / Your problem should look like: h = $- \frac{19}{19}$
Ninth, cancel out 19. / Your problem should look like: h = -1

Answer: h = -1
