If the point (a,3) lies on the graph of the equation 5x+y=8, then a=
scZoUnD [109]

Answer:

a = 1

Step-by-step explanation:

<u><em>The given equation is:</em></u>

=> 5x+y = 8

Also,

Point = (x,y) = (a,3)

So, x = a , y = 3

<u><em>Putting this in the above equation</em></u>

=> 5(a)+3 = 8

=> 5a = 8-3

=> 5a = 5

<em>Dividing both sides by 5</em>

=> a = 1

The admission fee at a local zoo is $1.50 for children and $5.00 for adults. On a certain day, 3000 people enter the zoo and $9,
vlabodo [156]

1600 children and 1400 adults attended

<h3>How to determine the number of adults?</h3>

Let the children be x and adult be y.

So, we have the following equations:

x + y = 3000

1.5x + 5y = 9400

Make x the subject in x + y = 3000

x = 3000 - y

Substitute x = 3000 - y  in 1.5x + 5y = 9400

1.5(3000 - y) + 5y = 9400

Expand

4500 - 1.5y + 5y = 9400

Evaluate the like terms

3.5y = 4900

Divide both sides by 3.5

y = 1400

Substitute y = 1400 in x = 3000 - y

x = 3000 - 1400

Evaluate

x = 1600

Hence, 1600 children and 1400 adults attended

Please help me with this problem !!!!!!
iren [92.7K]

Answer:

see explanation

Step-by-step explanation:

Given

s(t) = 10t²

To find s(2) and s(5) substitute t = 2 and t = 5 into f(t)

(a)

s(2) = 10 × 2² = 10 × 4 = 40

s(5) = 10 × 5² = 10 × 25 = 250

(b)

s(5) - s(2) = 250 - 40 = 210

This represents the distance travelled in 3 hours

(c)

The average rate of change is measured as

\frac{s(5)-s(2)}{5-2}

= \frac{250-40}{3}

= \frac{210}{3}

= 70 miles per hour
