Given: triangle ABC and triangle EDC, C is the midpoint of BD and AE.
Prove: AB || DE
Step-by-step explanation:
1. ΔABC=ΔCDE: a) according to the condition BC=CD and AC=CE; b) m∠(BCA)=m∠(DCE).
2. if ΔABC=ΔCDE, then m∠(BAC)=m∠(DEC) and m∠(ABC)=m∠(CDE).
3. if m∠(BAC)=m∠(DEC), then AB || DE (or if m∠(ABC)=m∠(CDE), then AB || DE).

Write the slope intercept form of the equation with slope 8 and y intercept (0,7)
Answer:
y=8x+7
Step-by-step explanation:
Use the form y=mx+b
M= the slope
B= the y-intercept
y=8x+?
Since the y coordinate of (0,7) is 7
b=7
So y=8x+7

A farmer owns a total of 9 acres of land. The land is separated into 4 2/7 equally sized sections. How many acres are in each section?
Answer:
[tex]2\dfrac{1}{10}\ \text{acres}[/tex]
Step-by-step explanation:
[tex]9[/tex] acres of land split into [tex]4\dfrac{2}{7}[/tex].
Now
[tex]4\dfrac{2}{7}=4+\dfrac{2}{7}[/tex]
One section of land will be
[tex]\dfrac{9}{4+\dfrac{2}{7}}\\ =\dfrac{9}{\dfrac{30}{7}}\\ =\dfrac{63}{30}\\ =\dfrac{21}{10}=2\dfrac{1}{10}\ \text{acres}[/tex]
One section of the land is [tex]2\dfrac{1}{10}\ \text{acres}[/tex].

How much time required to complete a10days work if it could complete by 3 worker in 4days and 6worker in 3.05 days,if 5 workers is involved in it? please reply
Answer:
This seems to be a linear relationship:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
We know that 3 workers can complete the job in 4 days.
Then if we define W as the rate at which a single worker can complete the work, we have the ordered pair (3 workes, 4 days)
And we also know that 6 workers can finish the job in 3.05 days, then we also have the ordered pair (6 workers, 3.05 days)
Then using these two, we can find the slope of the line:
a = (3.05 days - 4 days)/(6 workers - 3 workers) = -0.35 days/worker.
Then we have the equation:
y = (-0.35 days/worker)*x + b
Where:
y represents the time to complete the job
x represents the number of workers.
b is the y-intercept, to find the value, we could just replace one of the points in the equation, for example with the point (3 workes, 4 days) we need to replace x by 3 workers, and y by 4 days:
4 days = (-0.35 days/worker)*3 workers + b
4 days = -1.4 days + b
4 days + 1.4 days = 5.4 days = b
then the equation is:
y = (-0.35 days/workers)*x + 5.4 days.
Now we can find the number of days needed for 5 workers to finish the job, we just need to replace x by 5 workers:
y = (-0.35 days/workers)*5 workers + 5.4 days
y = 3.65 days.

What inequality is represented by this graph? A. x > 6 B. x _< 6 C. x < 6 D. x _> 6
Answer:
x<6
Step-by-step explanation:
b. x≤6
so the empty circle means it's (in this case) less than or equal to 6. the < looks like an L, so think, L is for Less than. Also, the < looks like part of <-, so that's the way the arrow points! hope this helps, good luck!
Factor the equation
Answer:
y = (x + 4)²
Step-by-step explanation:
Given equation is,
y = x²+ 8x + 16
By using identity (a + b)² = a² + 2ab + b²
y = x² + 2(4)(x) + 4²
Here a = x and b = 4
y = (x + 4)²
Therefore, factored form of the given equation is y = (x + 4)²

Use the number line.
Find WY=
Answer:
WY = 12 units.
Step-by-step explanation:
Given the number line
The location of W is at x = -5The location of X is at x = -1The location of Z is at = 4The location of Y is at = 7The distance between W and Y can be calculated such as:
WY = [Location of Y] - [Location of W]
WY = [7] - [-5]
WY = 7+5
WY = 12
Therefore, WY = 12 units

Step-by-step explanation:
because there are 28 properties in all
4 of them are railroads
but we're not looking for the probability of selecting a railroad, which would be 4/28 or 1/7, but for not selecting a railroad
and 24 of them are not railroads
So the probability of not selecting a railroad is 24/28, which simplified/reduced is 6/7
If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)?
5x3 + 9x2 + 15x + 27
25x2 + 90x + 84
x2 + 5x + 12
5x2 + 24
Answer:
5x3+9x2+15x+27
Step-by-step explanation:
The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find the product of m(x) and n(x), we need to multiply the two polynomials term by term:
m(x) = x² + 3
n(x) = 5x + 9
mn(x) = (x² + 3) (5x + 9)
Multiplying the two polynomials using the distributive property.
mn(x) = 5x³ + 9x² + 15x + 27
Thus,
The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.
