find the slope of the line passing through the points (9,-9) and (1,-1)

Answers

Answer 1

Answer:

The slope is -1

Step-by-step explanation:

Slope formula:

In (9,-9):   9 is x1 and -9 is y1

In (1,-1):      1 is x2 and -1 is y2

m= y2-y1/x2-x2

m= -1+9/1-9

Which is 8/-8

Simplify:

-1

The slope is -1

Hope this helps!

Answer 2

Answer:

-1

Step-by-step explanation:

To find slope, take the two points and find the RISE/RUN, which is y-y/x-x. Stay consistent with how you order the numbers. In this case, I'll do -1 -(-9) / 1 - 9. That will give you 8/-8, which when simplified gives you -1.

The length of a rectangle measures 5/8 of a foot. The width of the rectangle measures 2 1/2 feet. What is the area of the rectangle?

Answers

Answer:

1 9/16 square feet  or 1.5625 square feet

Step-by-step explanation:

Area of a rectangle is Length x Width

First convert 2 1/2 into a number that is just a fraction.

2 = 4/2  so 4/2 + 1/2 = 5/2

Now you can multiply the two fractions to find the area.

area = 5     5       25

          --  x  --   = -----

          8      2       16

To simplify this, you know 16/16 = 1  so subtract 16 from the numerator which leaves 9/16

Your answer will be 1 and 9/16

2 1/2 multiplied by 5/8 = 1.5625

Answers

Answer:

Brainliest Please

Step-by-step explanation:

10 year: $1000000

20 years: $2000000

Answer:

10 years = 8,900.00.

20 years = 23,200.00.

Step-by-step explanation:

Hey, let me tell you how to solve this; I had trouble as well.

Since the policy is worth 100,000, you divide this by 1,000.

That gives us 100.

Now, multiply 100 by the 10 yr cash value, which is 89.

That results in 8,900.00.

Taking 100 again, multiply it by the 20 yr cash value, 232.

That gives us 23,200.00.

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

3.2      Solve  :    x = 0  

 Solution is  x = 0

Equation of a Straight Line

3.3     Solve   f+x+3  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  f+x+3  = 0 and calculate its properties

Graph of a Straight Line :

 

 

Calculate the Y-Intercept :

Notice that when x = 0 the value of f is -3/1 so this line "cuts" the f axis at f=-3.00000

 f-intercept = -3/1  = -3.00000  

Calculate the X-Intercept :

When f = 0 the value of x is -3/1 Our line therefore "cuts" the x axis at x=-3.00000

 x-intercept = -3/1  = -3.00000  

Calculate the Slope :

Slope is defined as the change in f divided by the change in x. We note that for x=0, the value of f is -3.000 and for x=2.000, the value of f is -5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.000 - (-3.000) = -2.000 in f. (The change in f is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -2.000/2.000 = -1.000  

Geometric figure: Straight Line

 Slope = -2.000/2.000 = -1.000

 x-intercept = -3/1 = -3.00000

 f-intercept = -3/1 = -3.00000

x = 0

b) What will her salary be in 2021?

Answers

Answer:

in 2021, $40 202.87

Step-by-step explanation:

2015 is $30 000 per year

if it is increased by 5% every year

then,

in 2019, her salary will be $30 000 x (1.05)^4 = $36 465.19

in 2021, her salary will be $30 000 x (1.05)^6 = $40 202.87

Find the vertex of a quadratic function written in standard form.
f(x) = 3x2 + 18x + 32
PLS HELP!!

Answers

Answer:

our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )

Step-by-step explanation:

let me write the standard form of a quadratic equation

[tex]a {x}^{2} + bx + c[/tex]

Now let me rewrite the original equation

[tex]3 {x}^{2} + 18x + 32[/tex]

Now we use this simple formula to find the vertex (h, k)

[tex]x = h = - \frac{b}{2a} \\ = - \frac{18}{2(3)} = - \frac{18}{6} = - 3 \\ h = - 3[/tex]

substitute -3 for x back into our original equation to solve for y our k value of our vertex

[tex]y = 3 ({ - 3})^{2} + 18( - 3) + 32 \\ = 3(9) - 54 + 32 \\ = 27 + 32 - 54 \\ = 59 - 54 \\ k = 5[/tex]

our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )
