Tamara bought yarn for $39 and 2 pairs of knitting needles. Her total cost for the yarn knitting was 69. Tamara writes an equation for that represent the cost of each pair of knitting needles. If I represent the cost of each pair of knitting needles, which statements about verifying the value of k are true?

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

a rotation about point l
