What is the equation in point-slope form of the line that passes through the point (−1, −4) and has a slope of –3 ?

Answers

Answer:

y + 4 = -3(x + 1)

Step-by-step explanation:

point-slope form : y - y2 = m (x - x2)

In this case m = -3 and x2 = -1, y2 = -4

The equation in point-slope form

y + 4 = -3(x + 1)

Rupert drove home at an average rate of 58 miles per hour. Find his rate in feet per second.

Answers

To find this, you must first multiply 58 by the number of feet in a mile, 5280, to get a total number of feet. This comes out to 306,240 feet per hour. Next, you divide this by 60, since there are 60 minutes per hour, to find the rate of feet per minute, which comes out to 5,104 feet per minute. Finally, you divide this number by 60 again, since there are 60 seconds per minute, to get the final answer of a rate of about 85.0666... feet per second.

brainly.com/question/8182874

Step-by-step explanation:

Answer:

Area: 5π/2 in²

Perimeter: (3π+2) in

step-by-step explanation:

Area =

larger semicircle + small semicircle

= ½(pi × r1²) + ½(pi × r2²)

r1 = 2 in

r2 = 2/2 = 1 in

Area:

½(pi × 2²) + ½(pi × 1²)

= 2pi + ½pi

= 5pi/2 in²

Perimeter:

½(2pi × r1) + ½(2pi × r2) + r1

½(2pi × 2) + ½(2pi × 1) + 2

2pi + pi + 2

3pi + 2

4x times -2x = -8x

4x times -5 = -20x

3 times -2x = -6x

3 times -5 = -15

combine like terms

-8x - 20x - 6x = -34x

PEMDAS
simplify parenthasees first
then mulitplicationthen division
then addition and subtraction
6/2(1+2)
if it is
(6/2)(1+2) then go to AAAAAAAA

if it is 6/(2(1+2)) then go to BBBBBBBBB

AAAAAAAAAA
(6/2)(1+2)
simplify 6/2
2/6=3
also simplify 1+2
1+2=3
(3)(3)=9

BBBBBBBB
6/(2(1+2))
simplify inner parthenasees first
1+2=3
6/(2(3))
multiply with parenthaseess
2(3)=6
6/6=1

theh answer is either 9 or 1 depending on where the parenthasees is

you divide 6 by 2 which is 3 then you add 2 by 1 which is 3 which is 9
