Y = a(b^x)

y=mx + b is the equation of a line. It is a linear function because it has a constant rate of change.

y = a(b^x) is an exponential function because it has has an exponent and its rate of change is not constant

Papessa [141]

Answer:

let second side be x

then first side = x-13

third side= x+1

now

perimeter of triangle = 45

x-13+x+x+1=45

3x=57

x=19

(100 points) find the cost of each treat

Anna71 [15]

Answer:

icecream = $2.99

donut = $1.19

creamcake = $4.99

Step-by-step explanation:

The picture shows $7.17 for 2 x ice-cream and 1 donut

We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99

9.17- 4.99=4.18

=5.37-4.18 =1.19

we can then fill out the boxes.

1.19 +1.19 = 2.38 = 5.37-2.38= £2.99

2.99 +2.99 +1.19 = $7.17

We can see total first two rows = $12.56

2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56
