How do I graph y+x= -3

Mathematics
1 answer:
Nitella [24]3 years ago
7 0

Answer:

Use Desmos.com/calculator

Step-by-step explanation:

Remember, y=mx+b

y is equal to any given y point

x is equal to any given x point

m is equal to slope

b is equal to the y-intercept, or where x = 0 and the line crosses the horizon line.

In order to graph the line correctly, you have to isolate y.

y+x=-3

y=-x-3 would be equal to y=mx+b format

slope is negative 1

y intercept is negative 3

start on the y line, go to (0,-3) and start your line.

slope is negative 1, so you go down one and right one.

A parking lot charges $3 to park a car for the first hour and $2 per hour after that. If you use more than one parking space, th

Consider the charge for parking one car for t hours.

If t is more than 1, then the function is y=3+2(t-1), because 3 $ are payed for the first hour, then for t-1 of the left hours, we pay 2 $.

If t is one, then the rule y=3+2(t-1) still calculates the charge of 3 $, because substituting t with one in the formula yields 3.


75% is 75/100 or 0.75. 

For whatever number of hours t, the charge for the first car is 3+2(t-1) $, and whatever that expression is, the price for the second car and third car will be 

0.75 times 3+2(t-1). Thus, the charge for the 3 cars is given by:

3+2(t-1)+0.75[3+2(t-1)]+0.75[3+2(t-1)]=3+2(t-1)+<span>0.75 × 2[3 + 2(t − 1)].


Thus, the function which total parking charge of parking 3 cars for t hours is:

</span><span>f(t) = (3 + 2(t − 1)) + 0.75 × 2(3 + 2(t − 1))

If t=0 in 1980, find the value of A. Round answer to the nearest million.
balu736 [363]

P=Ae^kt

225 = 210 * e^(k*(1990-1980)

225/210=e^10k ln(225/210)=10k

k=ln(225/210)/10=0.0069

P = 210*e^(0.0069t)

for 2000 ===> t = 2000-1980=20

P = 210*e^(0.0069*20)

P=241.0749=241

What is the measure of ZB?​
brilliants [131]

Answer:

∠ B = 116°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , that is

∠ B + 28° + 36° = 180°

∠ B + 64° = 180° ( subtract 64° from both sides )

∠ B = 116°
