Answer:
Step-by-step explanation:
∠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

why is -2/4 bigger than -7/12
Answer:
-2/4 can be written as -6/12
in negetive integers:: if the numerical vallues goes on increasing then the numbers are in decreasing order

A city bus goes 18miles in 30 minutes . HOW far does it go in 2 minutes?
Answer:
the city bus would cover 6 miles in 10 minutes.
Step-by-step explanation:
18 miles = 30 minutes
? miles = 10 minutes
cross multiply
? x 30 = 18 x 10 (180)
? = 180/30
? = 6
the city bus would cover 6 miles in 10 minutes.
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:

Answer:
( x - 1 ) ( x + 2 )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

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.

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

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

but what's the question?
Easy math problem.....
Answer:
A should be correct.
Step-by-step explanation:
Given, a = 1/2 and b = -1/3
First, let's solve the numerator. Then we have:
1/2 - 1/3
= 1/6
Since we found out our numerator, It is time to find out our denominator.
We have:
1/2 x -1/3
= -1/6
Since we now know the numerator and the denominator, we can now find out what is a+b/ab. We can find that by adding the numerator and denominator.
1/6 divided by -1/6 is equaled to -1.
Therefore, A should be correct.

Step-by-step explanation:
1/2 + -1/3
-------------
1/2 x -1/3
First, make 1/2 and -1/3 have the same denominator
1/2 x 3/3 = 3/6
-1/3 x 2/2 = -2/6
Add
3/6 + -2/6 = 1/6
Multiply
1/2 x -1/3
1 x -1
-------
2 x 3
= -1/6
This makes the big equation
