Which equation of an exponential function has a graph that passes through the points

Mathematics

Karolina [17]3 years ago

Answer:

y = \frac{5}{3} (3^{x} )

Step-by-step explanation:

In general, y = k(b^{x})

Substitute x = 2, y = 15

(1)      15 = kb^{2}<u />

Substitute x = 1, y = 5

(2)      5 = kb^{1} = kb

Divide equation (1) by equation (2)

\frac{15 = kb^{2} }{5= kb }

3 = b

Now substitute b = 3 in equation (2) to find k

5 = k(3)

k = \frac{5}{3}

Since we know the values for k and b, we now have the exponential function that passes thru (1, 5) and (2, 15)

y = \frac{5}{3} (3^{x} )

At the park, 4/7 of the children are boys. if there are 8 boys at the park, how many are girls?
Oksana_A [137]
There are 4/7 boys, so there are 3/7 girls.

Let the total number of children be x.

4/7x = 8
1/7x = 8 ÷ 4
1/7x = 2
3/7x = 2 x 3
3/7x = 6

There are 6 girls.

PLEASE HELP ASAP!!!!!!!!!! EASY MATH 25 PTS
Harman [31]

its not worth 25 points but ok here u go let's solve your equation step-by-step.

3y−1=13−4y

Step 1: Simplify both sides of the equation.

3y−1=13−4y

3y+−1=13+−4y

3y−1=−4y+13

Step 2: Add 4y to both sides.

3y−1+4y=−4y+13+4y

7y−1=13

Step 3: Add 1 to both sides.

7y−1+1=13+1

7y=14

Step 4: Divide both sides by 7.

7y

7

=

14

7

y=2

Answer:

y=2 so there your answer is this equation has one solution  your welcome
