Answer:
Step-by-step explanation:
To solve:
|2x+1|=9
|2x+1|=-9
2x=8
x=4
2x=-10
x=-5
2x+1=9
2(4)+1=9
9=9, so its true.
2x+1=-9
2(-5)+1=-9
-9=-9, so it’s true too

A triangle is a three-edged polygon with three vertices. The area of the ΔDNE is 533 meters². The correct option is B.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The area of the triangle is half the product of its base and its height.
Area of triangle = (1/2) × base × height
Given the base of the triangle is 41 meters, while the height of the triangle is 26 meters.
Now, the area of the triangle DNE is,
Area of triangle = (1/2) × base × height
Area of ΔDNE = (1/2) × 41 meters × 26 meters
= 533 meters²
Hence, the area of the ΔDNE is 533 meters².

ill mark brainlist plss help
to find the area of the rectangle it is is length x width so we do 3x4=12. then area of triangle is base x height divide by 2, so 2x4=8. 8 divide by 2 is 4, then we need to add them all up, so 12 + 4 + 4 is 20. Your answer is 20 cm2.

How to determine the domain of a function based on a given graph
The domain of a function represents the set of coordinates in the x-axis that belongs to the curve of the function itself. After a brief inspection, we see that function has an horizontal asymptote at [tex]y = 1[/tex] and no vertical asymptotes. Therefore, the domain of the function shown is [tex]-\infty \le x \le +\infty[/tex]. [tex]\blacksquare[/tex]

American Vending supplies vended food to a large university. Because students often kick the machines out of anger and frustration, management has a constant repair problem. The machines break down in a mean of 3 hours with a standard deviation of 3 hours. One repair worker can service one machine in a mean of 2 hours with a standard deviation of 2 hours. Currently, TWO repair workers are hired. Average flow time (W) was calculated as 2.305 from the posted queueing template. --- Average down machines in the entire system (L) are ___.
Answer:
0.77
Step-by-step explanation:
From the information given:
The breakdown time (a)= 3 hours
The breakdown rate (λ) = 1/a = 1/3
Average flow time in the system (W) = 2.305 hours
For the entire system;
The average down machines L = Wλ
= 2.305 × (1/3)
= 0.77

compare these two fractions
Answer:
4/6 is more than 5/12
Step-by-step explanation:
First, set the denominators of the fractions equal to eachother to make it easier to compare. mulitiply 6 and 4 by 2 so that the denominator now equals 12, and you have the new fractions 5/12 and 8/12. Since 8/12 is more than 5/12, 4/6 is more than 5/12.
Answer:
5/12 is greater than 4/6
Step-by-step explanation:
using the butterfly method, multiplying 12 x 4 = 48
and 6x5=30 48 is more than 30
48 Stands for 5/12
30 stands for 4/6

Solve the system of equations by substitution method. Y=3x+7. y=5x+8
Answer:
Y=3x+7
y=5x+8
3x + 7 = 5x + 8
-1 = 2x
x = -1/2
y = 3(-1/2) + 7
y = -3/2 + 7
y = 5.5
x = -0.5 ; y = 5.5
Answer:
x = [tex]-\frac{1}{2}[/tex] y = 5.5
Step-by-step explanation:
substitution method
3x + 7 = 5x + 8
subtract 3x from both sides
7 = 2x + 8
subtract 8 from both sides
-1 = 2x
divide each side by 2
x = [tex]-\frac{1}{2}[/tex]
substitute the x in either equation
y = 3(-1/2) + 7
y = -1.5 + 7
y = 5.5
or
y = 5(-1/2) + 8
y = -2.5 + 8
y = 5.5
