Answer:

All these graphs intercept the y-axis at 4 OR

All these graphs b = 4

All these graphs have a slope or are non-vertical

Step-by-step explanation:

y = 3x + 4

y = 2x + 4

y = -x +4

y = -5x + 4

All these graphs intercept the y-axis at 4

slope intercept equation is y = mx + b, the line intercepts the y-axis at b

In addition, all these graphs have a slope or are non-vertical

Betty collected 400 food packages for charity. She gave g packages to an orphanage, and distributed the rest equally among 4 cha

Mariana [72]

So this is an equation.
The starting value is the given value 400.
She gave g packs to the orphanage, so she now has 400-g packages.
Then she divides that by 4 and gives to 4 different charities.
The answer is (400-g)÷4
Hope this helps!

Use technology to determine an appropriate model of the data. (-1,0), (1,-4), (2,-3), (4,5), (5,12)

goblinko [34]

An appropriate model is a quadratic, y=0.999x²-1.999x-3.

The r² value is 1, so it is a perfect fit.

Use the sum of cubes factoring rule

$a^3 + b^3 = (a+b)(a^2 - ab + b^2)$

to transform the left hand side into the right hand side.

$\frac { \sin^{3} \theta + \cos^{3} \theta } { \sin \theta + \cos \theta } = 1 - \sin \theta \cdot \cos \theta\\\\\frac { (\sin \theta + \cos \theta)(\sin^2 \theta - \sin \theta \cdot \cos\theta + \cos^2 \theta) } { \sin \theta + \cos \theta } = 1 - \sin \theta \cdot \cos \theta\\\\$

$\sin^2 \theta - \sin \theta \cdot \cos\theta + \cos^2 \theta = 1 - \sin \theta \cdot \cos \theta\\\\(\sin^2 \theta + \cos^2\theta)- \sin \theta \cdot \cos\theta = 1 - \sin \theta \cdot \cos \theta\\\\1- \sin \theta \cdot \cos\theta = 1 - \sin \theta \cdot \cos \theta \ \ \checkmark\\\\$

Throughout the entire process, the right hand side stayed the same.

On the last step, I used the pythagorean identity.

The function f(x) is represented by the table below. What are the corresponding values of g(x) for the transformation g(x)=2f(x)

malfutka [58]

Answer:

see the explanation

Step-by-step explanation:

we know that

g(x)=2f(x)

Find the value of g(x) for the corresponding value of f(x)

1) For x=-6, f(x)=2

Substitute

g(x)=2f(x)

g(x)=2(2)=4

2) For x=-2, f(x)=2

Substitute

g(x)=2f(x)

g(x)=2(2)=4

3) For x=0, f(x)=6

Substitute

g(x)=2f(x)

g(x)=2(6)=12

4) For x=1, f(x)=3

Substitute

g(x)=2f(x)

g(x)=2(3)=6

4) For x=6, f(x)=-1

Substitute

g(x)=2f(x)

g(x)=2(-1)=-2
