If a and b are real numbers and if y = ax + b is a direct variation equation, what do you know about a and b?

1 answer:

8 0

y = ax + b
We observe that the given equation is the generic equation of a line.
Where,
a = represents the slope of the line. That is, the rate of change of the given function. (in this case it is constant).
b = is the cut point with the y axis.

Answer:

see explanation

Step-by-step explanation:

$\frac{2}{1+e^{-2} }$ ← evaluate $e^{-2}$ using calculator

= $\frac{2}{1+0.135}$

= $\frac{2}{1.135}$

= 1.762.....

≈ 1.8 ( to 1 dec. place )

list all the possible whole number length and width of rectangles that darla can cut from the 400 square inch piece of paper

Rufina [12.5K]

The possible dimension are :

400 = 1 x 400
400 = 2 x 200
400 = 4 x 100
400 = 5 x 80
400 = 8 x 50
400 = 10 x 40
400 = 16 x 25
400 = 20 x 20

Find the area of this irregular polygon.

Rainbow [258]

Answer:

970m^{2}

Step-by-step explanation:

This polygon can be divided in two figures: one is a triangle, an the other one is a square.

We'll begin calculating the triangle's area, using the following formula:

$At= \frac{b.h}{2}$

Where:

$H= height = 30 m$

$B = 9 m + 9 m + 20 m = 38 m$

As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.

$At= \frac{38 m .30 m}{2}$
