Which row of the input/output table is incorrect? y = 2 x - 3 x y Row A 3 3 Row B 5 7 Row C 7 11 Row D 10 15 Row B Row C Row A Row D
The row of the input/output is incorrect is Row D.
What is equation?
Given equation: y = 2x - 3
For, row A:
x = 3
y = 2x - 3
So,
y = 2(3) - 3
y = 3, which is correct
For row B:
x = 5
y = 2x - 3
So,
y = 2(5) - 3
y = 7, which is also correct.
For row C:
x = 7
y = 2x - 3
So,
y = 2(7) - 3
y = 11, which is also correct.
For, row D:
x = 10
y = 2x - 3
So, y = 2(10) - 3
y = 17, which is incorrect.
Hence, the row of the input/output is incorrect is Row D.

solve 2(x+7) +3 (x+1)
Answer:
5x +17Step-by-step explanation:
Simplify step by step:
2( x+7 ) +3 ( x+1 )
We'll distribute:
= ( 2 ) ( x ) + ( 2 ) ( 7 ) + ( 3 ) ( x ) + ( 3 ) ( 1 )
= 2x + 14 + 3x + 3
We'll Combine Like Terms:
= 2x + 14 + 3x + 3
= ( 2x + 3x ) + ( 14 + 3 )
= 5x + 17 Answer!
Answer:
Step by step Explanation:
2(x+7) +3(x+1)
Open the brackets (multiply outside number by the numbers and letters inside the brackets)
2x + 14 + 3x+ 3
Collect like terms (collect ones that look alike in one side )

Complete the table of inputs and outputs for the given function.
g(x)=3-8x
The inputs and outputs for the given function g(x) = 3 - 8x is (-3, 27), (-1, 11), (0, 3), (1, 5) and (3, 21).
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that g(x) = 3 - 8x, hence:
When x = -3; g(-3) = 3 - 8(-3) = 27
When x = -1; g(-1) = 3 - 8(-1) = 11
When x = 0; g(0) = 3 - 8(0) = 3
When x = 1; g(1) = 3 - 8(1) = 5
When x = 3; g(3) = 3 - 8(3) = 21
The inputs and outputs for the given function g(x) = 3 - 8x is (-3, 27), (-1, 11), (0, 3), (1, 5) and (3, 21).

If a +b+c+d+e= 576°, find the value
of angle f. Give your answer in degrees (°).
Answer:
f = 144 degrees
Step-by-step explanation:
Since there are 6 angles (a,b,c,d,e,f), this means that it is a 6-sided polygon. The formula to find the total sum of interior angles is (n-2)*180, n being the amount of sides.
Let's plug it into the formula: (6-2)*180 = 720
This means that a+b+c+d+e+f = 720, but we can substitute (a+b+c+d+e) for 576.
576+f=720
f = 144 degrees
Jessica wants to plan where she will place furniture in her room, so she has drawn a scale model of her room in order to begin planning. the scale model is 11 inches long and 8.5 inches wide. jessica notices that the door to her room takes up 1.75 inches on the right-side wall of her room, and she realizes that she cannot place any furniture in the area that the door turns through when it is opened. if the longest wall in jessica’s actual room is 15 feet long, what is the best estimate of the area of the actual space in her room where furniture cannot be placed because of the door? 6 ft 2 6.5 ft 2 18 ft 2 9 ft 2
Answer:
(d) 9 ft²
Step-by-step explanation:
To find the excluded area for furniture, we can find the actual size of the door, then compute the area of the semicircle that it turns through. The door size will be the product of the drawing dimension and the scale factor relating the room to the drawing.
__
door sizeRoom size and drawing size are proportional. This means ...
door size / door drawing = room length / room drawing
door size / (1.75 in) = (15 ft)/(11 in)
door size = (15 ft)(1.75/11) = 105/44 ft ≈ 2.386 ft
__
exclusion areaThe area of a circle with radius r is given by the formula ...
A = πr²
Then the area of a semicircle (half a circle) with radius 2.386 ft will be ...
A = 1/2π(2.386 ft)² ≈ 8.945 ft²
A good estimate of the furniture exclusion area is 9 ft².
_____
Additional comment
The scale factor is (15 ft)/(11 in) = 15/11 ft/in. Multiplying that by 7/4 in gives 105/44 ft.

Find an angle between 0 degrees and 360 degrees and that is coterminal with 1260 degrees.
Answer:
The 180 degrees angle.
Step-by-step explanation:
We can start by dividing 1260 / 360 = 1080. Therefore, a 1080 degrees angle would be coterminal with 360.
Now we take 1260 - 1080, to see how many degrees we have left, this gives us: 180, therefore, the angle between 0 and 360 that is coterminal with 1260 degrees is the 180 degrees angle.
Find the value of x that makes line m parallel to line n.
Answer: x = 20
Step-by-step explanation:
If line m is parallel to line n, the two angles given will be congruent because they will be alternate exterior angles (which are congruent).
This means we will set them equal to each other and solve for x.
Given:
(4x - 23) = (2x + 17)
Add 23 to both sides of the equation:
4x = 2x + 40
Subtract 2x from both sides of the equation:
2x = 40
Divide both sides of the equation by 2:
x = 20

(2*2*1.5*1/3)+(2*1.5*4)= 14
Step-by-step explanation:
To find the area of a pyramid, you use the equation of 1/3 *lwh. When we place the values in there, we get 2*2*1.5*1/3, which is equal to 2. Then we solve the bottom part. Since it is a rectangular prism, we use the equation of lwh. When we insert the values, we get 2*1.5*4, which is equal to 12. Now, we take these two values of 2 and 12 and we combine them, giving us our final answer of 14.

(-4,1) and (2,-3) find length and midpoint of segment
Step-by-step explanation:
the length is calculated via Pythagoras, as the coordinate differences and the direct connection (as the Hypotenuse) between both points create a right-angled triangle.
length² = (-4 - 2)² + (1 - -3)² = (-6)² + 4² = 36 + 16 = 52
length = sqrt(52) = sqrt(4×13) = 2×sqrt(13)
the midpoint is simply ((x1+x2)/2, (y1+y2)/2)
so,
(-4 + 2)/2 = -2/2 = -1
(1 + -3)/2 = -2/2 = -1
therefore, the midpoint is (-1, -1)
