The number line shows the distance in meters of two jellyfish, a and b, from a predator located at point x: a horizontal number line extends from negative 3 to positive 3. the point a is at negative 1.5, the point 0 is labeled as x, and the point labeled b is at 0.5. write an expression using subtraction to find the distance between the two jellyfish. (5 points) show your work and solve for the distance using additive inverses. (5 points

The distance between the two jellyfish is 0.5 - (-1.5)

To solve using additive inverse 0.5 - (-1.5) = -(-0.5 - 1.5) = -(-2) = 2.

Step-by-step explanation:

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

b. astronomers
