Find the points of intersection of the following function graphs: y=14−2.5x and y=1.5x−18 PLEASE HELP ONLY HAVE 20 MINUTES
Korolek [52]

Answer:x=8 Y=-6

Step-by-step explanation:

14-2.5x=1.5x-18

+18. +18

32-2.5x=1.5x

+2.5x =2.5x

32= 4x

Divide 4 to both sides you get

8=x

Y=14-2.5(8)

Y=14-20

Y=-6

One year after you buy a tree, it is 12 feet tall. Each year after you buy the tree, it grows 4 feet. Write a function that repr
Svetllana [295]

Answer:

5 years

Step-by-step explanation:

Since the tree grows 4 feet every single year and the second year it was 12 feet tall then that means that when you bought the tree it was 8 feet tall (12-4 = 8). Therefore, using these values we can write an equation to calculate the number of years it will take for the height of the tree to be 28 feet. We do this by multiplying 4ft by the variable of a number of years (x) and then adding that product to 8ft which is the initial height. All of which should add up to 28 ft.

28 ft. = 8 ft. + 4x    ... subtract both sides by 8

20 ft. = 4x   ... divide both sides by 4

5 years = x

Therefore, it will take 5 years from the initial purchase for the tree to be 28ft tall.

Pleasee help me! Find the measure of <a + <b + <c + <d + <e + <f. Explain ​
larisa86 [58]

Step-by-step explanation:

By sum of angles on a straight line = 180°,

we have Angle A + Angle B = 180°,

Angle C + Angle D = 180°, and

Angle E + Angle F = 180°.

Hence Angles A + B + C + D + E + F = (180°) + (180°) + (180°) = 540°.
