Answer:
10
Step-by-step explanation:
1. Any number has a denominator of 1 so you have 6/1 and 8/2.
2. To add you need to make the denominators the same so multiply the 2 to the numerator and denominator of 6/1 which makes 12/2.
3. 12/2+8/2 is 20/2.
4. Simplify 20/2 by dividing the top and bottom by 2 to get 10/1.

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?
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
What is the value of z?
Answer:19
Step-by-step explanation:
find the slope of the line passing through the points (9,-9) and (1,-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:
-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.

Write the quadratic equation the has the roots (-1-√2)/3 and (-1+√2)/3 if its coefficient with x^2 is equal to...1
Step-by-step explanation:
x1+x2 = (-1-√2)/3 + (-1+√2)/3
= -2/3
(x1) (x2) = (-1-√2)/3 × (-1+√2)/3
= -1/9
the equation :
x² -(-2/3)x + (-1/9) = 0
x² + ⅔ x - 1/9 = 0
Factor the expression
Answer:
(x−1)(x+2)(x+2)

Step-by-step explanation:
→ Factor out 4x - 4
4 ( x - 1 )
→ Rewrite
x² ( x - 1 ) + 4x ( x - 1 ) + 4 ( x - 1 )
→ Factor out x - 1
x - 1 ( x² + 4x + 4 )
→ Factor the quadratic inside
( x - 1 ) ( x + 2 )²

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
Find the value of X.

∠K = ∠c
∠K = 3x - 5
∠K + ∠M + ∠L = 180 {angle sum property of triangle}
3x -5 + 40 + 2x = 180
3x + 2x - 5 + 40 = 180
5x + 35 = 180
5x = 180 - 35
5x = 145
x = 145/5
x = 29

Jane Rogers has a $100,000 whole life policy. What will the cash value of her policy be at the following anniversary dates?(Use a thousands comma where applicable.)Anniversary dateCash Value10 year$20 year$
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.

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

is increased by 5%.
In 2016 her salary will be
30 000 x 1.05 = $31 500
In 2017 her salary will be 30 000 x 1.05 X 1.05 = $33075
In 2018 her salary will be 30 000 x 1.05 x 1.05 x 1.05 = $34728.75
And so on.
a). What will her salary be in 2019?
b) What will her salary be in 2021?
Answer:
in 2019, $36 465.19
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

The length of the side AB and AC will be congruent with each other. Then the triangle ΔABC will be an isosceles triangle.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The two triangular legs and their opposing angles are congruent in an isosceles triangle.
In triangle ΔABC, then the length of the side AB and AC will be congruent to each other.
AB = AC
Then the triangle ΔABC will be an isosceles triangle.
