Ok
1. m=1/3; (2,-3)
use point-slope form first. (y-y₁)=m(x-x₁)
(y+3)=1/3(x-2)
y+3=1/3x-2/3
y-1/3x=-3 2/3
just follow the same rule for the other questions
sorry am in class and have other stuff to do
3( x - 1 ) = 2 x + 5
Expand 3(x-1) :
3*x - 3 x 1
3 x - 3 = 2 x + 5
Add 3 both sides :
3 x - 3 + 3 = 2 x + 5 + 3
3 x = 2 x + 8
3x - 2 x = 8
x = 8
hope this helps!
Answer:
The volume of the hemisphere is 496741.6 m³
Step-by-step explanation:
The volume of an sphere is given by:
In which 
and r is the radius.
An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So
In this question:
. So
The volume of the hemisphere is 496741.6 m³
1 inch of the model - 18 inches of the car
9 inches of the model - x inches of the car
The car is 162 inches long.
Equation in slope-intercept form is y = 2x - 6
Step-by-step explanation:
- Step 1: Given slope of the line, m = 2. Form an equation y = mx + b
⇒ y = 2x + b ---- (1)
- Step 2: The line passes through the point (4,2). So it will satisfy the equation. Find b by substituting x = 4 and y = 2.
⇒ 2 = 2 × 4 + b = 8 + b
⇒ b = -6
- Step 3: Form the slope-intercept equation.
⇒ y = 2x - 6
