3+c - (4+c)

pretend that there is a -1 in front of the bracket

3+c-1(4+c)

multiply the bracket by -1

(-1)(4)=-4

(-1)(c)=-c

3+c-4-c

3-4+c-c ( combine like terms)

+c-c=0

3-4=-1

-1+0=-1

Answer:

-1

Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x

Solnce55 [7]

Answer:

The equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x is $\mathbf{y=-\frac{2}{3}x+3 }$

Step-by-step explanation:

We need to Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x

The equation in slope-intercept form is: $y=mx+b$ where m is slope and b is y-intercept.

Finding Slope:

The both equations given are parallel. So, they have same slope.

Slope of given equation y= - 2/3x is m = -2/3

This equation is in slope-intercept form, comparing with general equation $y=mx+b$ where m is slope , we get the value of m= -2/3

So, slope of required line is: m = -2/3

Finding y-intercept

Using slope m = -2/3 and point (-3,5) we can find y-intercept

$y=mx+b\\5=-\frac{2}{3}(-3)+b\\5=2+b\\ b=5-2\\b=3$

So, we get b = 3

Now, the equation of required line:

having slope m = -2/3 and y-intercept b =3

$y=mx+b\\y=-\frac{2}{3}x+3$

The equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x is $\mathbf{y=-\frac{2}{3}x+3 }$

Answer:

x=3

Step-by-step explanation:

Right triangle so you can use pythagorean theorem

a squared + b squared = c squared

b=x

14^2 + b^2= 17^2

14+b=17

b=3

The Kamp family has twins, Rob and Rachel. Both Rob and Rachel graduated from college 2 years ago, and each is now earning $50,0

dybincka [34]

Answer:

z-value of rachel = 1.875

z-value of rob = -2

z-value of Rachel is more than that of rob. Thus rob is earning below average and rachel is earning above average.

Step-by-step explanation:

Let's denote the salary of Rob and Rachel per year by X. So, X = $50,000

We are told that;

For Rachel's industry;

Mean salary;μ1 = $35,000

Standard deviation;σ1 = $8,000

For Rob's industry;

Mean salary;μ2 = $60,000

Standard deviation;σ2 = $5,000

Formula for z - value is;

z = (X - μ)/σ

Thus;

z-value for rob is;

z2 = (X - μ2)/σ2

z2 = (50000 - 60000)/5000

z2 = -2

z-value for rachel is;

z1 = (X - μ1)/σ1

z1 = (50000 - 35000)/8000

z1 = 1.875

z-value of Rachel is more than that of rob. Thus rob is earning below average and rachel is earning above average.

What is the volume of the square pyramid round to the nearest thenth 10 cm 12 cm 12 cm

oksano4ka [1.4K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a square based pyramid is expressed as

Volume = 1/3 × base area × height

Since the base is a square, all sides would be equal. The formula for finding the area of a square would be applied. From the information given, length of each side of the square is 12 cm. Therefore,

Base area = 12² = 144 cm²

Height = 10 cm

Therefore,

Volume = 1/3 × 144 × 10 = 480 cm³

Instance variables are often called ____ to help distinguish them from other variables you might use. (3 pts.)

zzz [600]

Instance variables are often called "fields" to help distinguish them from other variables you might use.

<h3>What are Instance variables?</h3>

Instance variables are defined within a class but outside of any method, constructor, or block.

Some key points related to Instance variables are-

When heap space is allocated to an object, a slot is created for every instance variable value.
Whenever an object is created with keyword 'new,' instance variables are created, and they are destroyed whenever the object is destroyed.
Instance variables store values that need to be referenced by multiple methods, constructors, or blocks, as well as vital components of an entity's state which must be available throughout the class.
Before or after use, instance variables could be declared just at class level.
Variables, for example, can be given access modifiers.
Only those methods, constructors, and blocks in the class have access to the instance variables.
