Answer: Slope: 6-(-6)/2-(-4)=2

Slope:2

Write it in the standard form

Y=2x+b

Find the b

Substitute the y and x

6=2(2)+b

b=2

Here the equation=

Y =2x+2

A race

Answer: 187.7 mph

Step-by-step explanation:

v = 125 mph

t = 1.2 min

v2 = ?

t2 = 0.8 min

We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.

$\frac{125mph}{x} =\frac{1.2min}{0.8min}$

$x = \frac{(125)(1.2)}{0.8}$

$x=187.5mph$

HELP ME PLEASE I NEED THIS LOVE U GUYS <33

Sedaia [141]

Answer:

$\huge\boxed{\sf Volume = 384 \ cm^3}$

Step-by-step explanation:

Slant Height = 10 cm

Base Edge = 12 cm

<u>Finding the Height using Pythagorean Theorem:</u>

$\sf c^2 = a^2 + b^2 \\\\Where \ c = 10\ cm , b = 6\ cm [Half of 12] \ and \ a \ is \ height\\\\10^2 = a^2 + 6^2\\\\100=a^2 +36\\\\100-36 = a^2\\\\64 = a^2\\\\Taking \ sqrt \ on \ both \ sides\\\\Height= 8 \ cm$

$\rule[225]{225}{2}$

<u>Now, Finding the volume:</u>

$\sf Volume = a^2 \frac{h}{3}\\\\ Where \ a \ is base \ edge \ and \ h \ is \ height\\\\Volume = (12)^2 \frac{8}{3} \\\\Volume = 144 \frac{8}{3} \\\\Volume = 48*8\\\\\bold{Volume = 384 \ c m^3}$

$\rule[225]{225}{2}$

Hope this helped!

I need help with 3 please... I don’t know how to do it and I know my answer is wrong... please

harina [27]

It will take 20 hours I think because 8,16,32,64 is the sequence of cars waxed and 3,6,12,24 are the hours, 64 take 4 away = 60. and then 24, I took 4 away from 64 so it would be 20 if I took away 4

The solution of the equation 3(x+3)=12

vaieri [72.5K]

Answer:

Step-by-step explanation:

3(x + 3) = 12

Multiply 3 by both numbers in the parentheses.

3x + 9 = 12

Subtract 9 from both sides of the equation.

3x = 3

Divide 3 from both sides of the equation.

x = 1
