Answer: -3, -2/1 and negative

Step-by-step explanation:

y=mx+b

m is the slope and b is the y intercept

both of these are given

m=-2

b=-3

If you mark point (0,-3), your given y intercept, and use the given slope, -2, you can easily find your line, which declines going right.

Answer:

Part 1) The area of the figure is $A=48\ cm^2$

Part 2) The perimeter of the figure is $P=4(2+3\pi)\ cm$

Step-by-step explanation:

Part 1) Find the area of the figure

we know that

The area of the figure is equal to the area of three squares

$A=3[4^2]=48\ cm^2$

Part 2) Find the perimeter of the figure

we know that

The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)

Remember that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter of the circle

In this problem

$D=4\ cm$

$P=2(4)+3[\pi(4)]=(8+12\pi)\ cm$

simplify

$P=4(2+3\pi)\ cm$

Pls help to get the answer

soldier1979 [14.2K]

When they say quotient, they want a fraction, so the answer for that would be
$\frac{6}{10}$
and the decimal form of that would be 0.6. You can get that from dividing 6 by 10 and solving with long division.

Determine the x- and y-intercepts of the graph of y=−1/3x+3 .

Alinara [238K]

Answer:

x intercept

$y = 0 \\ 0 = \frac{1}{3} x + 3 \\ \frac{1}{3} x = - 3 \\ x = - 9$
