Which description is paired with its correct expression? four less than the quotient of a number cubed and seven, increased by three;
13
4-
7 +3
five times the difference of a number squared and six; 5(6-1)
nine more than the quotient of six and a number cubed, decreased by four;
9+
6
- 4
4
O twice the difference of nine and a number squared; 2(9-n?)

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

2x^2+5x+17

your welcome. : )

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
