Answer all of these for free points (10m-4)+(-9-2m)= (9x+14)-(4x+8)= (-v+23)-(10v-4) (-7-2k)-(9k+15)= (8y+15)+(10-6y)= (23h-14)-(-h+17)= i might give 200 free points

(10m-4)+(-9-2m)= 8−13

(9x+14)-(4x+8)= 5+6

(-v+23)-(10v-4)=−11+27

(-7-2k)-(9k+15)= −11−22

(8y+15)+(10-6y)= 2y+25

(23h-14)-(-h+17)=24ℎ−31

Step-by-step explanation:

(10m-4)+(-9-2m)= 8−13

(9x+14)-(4x+8)= 5+6

(-v+23)-(10v-4)=−11+27

(-7-2k)-(9k+15)= −11−22

(8y+15)+(10-6y)= 2y+25

(23h-14)-(-h+17)=24h−31

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
