james just bought a new car for 26,950 if it decreases in value by 15% annually how much will it be worth in five
puteri [66]
I believe the answer is 20212.5 if you meant how much will it be worth in 5 years.
I got this answer by multiplying 15% by 5 since annually means yearly.
15%(5)=75%
then turn 75% into a decimal by dividing 75 by 100
75/100=.75
Finally multiply 26950 by .75
26950 (.75)=20212.5

Hope this helps you.

MaRussiya [10]
Y=mx+b
m=slope
b=yint

y=16500-1500x
y=-1500x+16500

slope is -1500
yintercept is 16500

Answer:

20 units

Step-by-step explanation:

The polygon has 4 vertices as indicated by the 4 coordinate points given.

(3, 1) and (8, 1) is a horizontal side of length 8 - 3 = 5

Similarly

(3, 6) and (8, 6) is the opposite horizontal side of length 8 - 3 = 5

Points (3, 1) and (3, 6) is a vertical side of length 6 - 1 = 5

(8, 1) and (8, 6) is the opposite side of length 6 - 1 = 5

The polygon is therefore a square of side 5 units.

Perimeter = 4 × 5 = 20 units

Anyone??? Need help!!!

Answer:

x=45

Step-by-step explanation:

We know that this is a right isosceles triangle because it has a right angle (square) and a triangle has to add up to 180 degrees so 90+x+x=180

90+2x=180

2x=90

x=45

3x-z+2x+3y+2x<———— Can you please help me with solving this expression please?
SVETLANKA909090 [29]

Answer:

7x+3y-z

Step-by-step explanation:

Starting off by separating the different variables, you should get:

(3x + 2x ) + (-z + 2z) + (3y)

Then you simplify in between the parentheses...

(5x) + (z) + (3y)

And you finally simplify the equation with only a single number of a certain variable to get your answer...

5x + z + 3y
