Answer:

y = 4x+6

The input is 11 when the output is 50

Step-by-step explanation:

We need to find the slope of this function using 2 points

(3,18) and (0,6) are two points

m = (y2-y1)/(x2-x1) is the formula for slope

=(6-18)/(0-3)

-12/-3

The slope is 4

We know the y intercept. It is the value when x =0. The y intercept is 6

We can use the slope intercept form of the equation

y = mx+b, where m is the slope and b is the y intercept.

y = 4x+6

We want to know the input when the output is 50 (or y=50)

50 = 4x+6

Subtract 6 from each side

50-6 = 4x+6-6

44 = 4x

Divide by 4

44/4 = 4x/4

11=x

The input is 11

Answer:

y = 4x + 6

Step-by-step explanation:

Equation

y= mx + b

Givens

See table

Solution

Start with x = 0. It is always a good place to start.
x = 0
y = 6
y = mx + b
6 = m*(0) + b
6 = b
So far what you have is y= mx + 6
Choose any point to find m
I'll use (3,18)
y = mx + 6
18 = 3*m+ 6 Subtract 6 from both sides
18 - 6 = 3m + 6 -6 combine
12 = 3m Divide by 3
12/3 = 3m/3 Divide
4 = m

y = 4m + 6 Answer

When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constan

vitfil [10]

Answer:

$a = 6m/s^2$

Step-by-step explanation:

Given

When mass = 4kg; Acceleration = 15m/s²

Required

Determine the acceleration when mass = 10kg, provided force is constant;

Represent mass with m and acceleration with a

The question says there's an inverse variation between acceleration and mass; This is represented as thus;

$a\ \alpha\ \frac{1}{m}$

Convert variation to equality

$a = \frac{F}{m}$ ; Where F is the constant of variation (Force)

Make F the subject of formula;

$F = ma$

When mass = 4kg; Acceleration = 15m/s²

$F = 4 * 15$

$F = 60N$

When mass = 10kg; Substitute 60 for Force

$F = ma$

$60 = 10 * a$

$60 = 10a$

Divide both sides by 10

$\frac{60}{10} = \frac{10a}{10}$

$a = 6m/s^2$

<em>Hence, the acceleration is </em> $a = 6m/s^2$ <em />

Where did mathematics come from

Ganezh [65]

The most ancient mathematical texts came from mesopotamia and Egypt. The “inventors” of math are the Greek beginning in around the 6th century BC.

What is the area of the right triangle shown?

prisoha [69]

The 30:60:90 proportion is 1:sqrt 3: 2

So,

x = 10/2
x = 5

y = 10/sqrt 3

Finding the area:

1/2 * 5 * 10/sqrt 3
25/sqrt 3

Hope this helps!
