Answer:
A. 6x – 6
B. 2x²–15 +28
Step-by-step explanation:
A.
Perimeter = (length +width)×2
=[ (2x-7) + (x+4)] ×2
= ( 3x – 3)×2
= 6x – 6
B.
Area = length ×width
= (2x-7)(x-4)
= 2x²-8x-7x+28
=2x²-15x+28

If the triangle and a parallelogram standing on the same base and lying between the same parallels. Which of the following relation is appropriate?
Answer:
Step-by-step explanation:If a triangle and parallelogram are on the same base and have the same altitude, the area of the triangle will be half that of the parallelogram. If they have same altitude, they will lie between the same parallels. Hence the area of the triangle will be equal to half that of the parallelogram.

Step-by-step explanation:
x = 30°
180-30= 150
4x=150
x = 37.5
Answer:
Y = 40
Step-by-step explanation:
I do not understand that language but if it is asking what Y is equal to when x is equal to 30 degrees and EFG is a straight line.
1. 3Y + 2X = 180 (Straight angle)
2. X = 30 (given)
3. therefore 2X = 2x30
= 60
4. Therefore 3Y + 60 = 180
5. 3Y = 180 - 60
6. 3Y = 120
7. Y = 120/3
8. Y = 40

Step-by-step explanation:
Substitute the given values of x into f : x → [tex]\frac{3}{7}[/tex] x + 4
x = - 14 → ([tex]\frac{3}{7}[/tex] × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2
x = 28 → ( [tex]\frac{3}{7}[/tex] × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16
x = [tex]\frac{7}{8}[/tex] → ([tex]\frac{3}{7}[/tex] × [tex]\frac{7}{8}[/tex] ) + 4 = [tex]\frac{3}{8}[/tex] + 4 = [tex]\frac{3}{8}[/tex] + [tex]\frac{32}{8}[/tex] = [tex]\frac{35}{8}[/tex]
x = - [tex]\frac{2}{9}[/tex] → ([tex]\frac{3}{7}[/tex] × - [tex]\frac{2}{9}[/tex] ) + 4 = ([tex]\frac{1}{7}[/tex] × - [tex]\frac{2}{3}[/tex]) + 4 = - [tex]\frac{2}{21}[/tex] + [tex]\frac{84}{21}[/tex] = [tex]\frac{82}{21}[/tex]
Answer:
See below in bold.
Step-by-step explanation:
1. 3/7 * -14 + 4
= -6 + 4
= -2.
2. 3/7 * 28 + 4
= 12 + 4
= 16.
3 3/7 * 7/8 + 4
= 3/8 + 4
= 35/8 or 4 3/8.
4. 3/7 * -2/9 + 4
= -6/63 + 4
= -2/21 + 4
= -82/21 or -3 19/21.

The time required for a certain chemical reaction is related to the amount of catalyst present during the reaction.The domain of the relation is the number of grams of catalyst,and the range is the number of seconds required for a fixed amount of the chemical to react.The following relation is the data from several reactions:[(2,180),(2.5,6),(2.7,0.05),(2.9,0.001),(3.0,6),(3.1,6)(3.1,15)(3.2,37),(3.3,176)}.
A. Is the relation a function?
B. If the domain and range were interchanged,would the relation be a function?Explain.
"Relation is a function if the terms in domain corresponds a unique value in range"
A). Given relation is a function.
B). Interchanged relation will not be a function.
A). From the given ordered pairs, x-coordinate represents the term of Domain and y- coordinate represents the Range.
We find each term of domain is associated with a unique term in range.
Therefore, relation is a one-to-one function.
B). If the terms in range and domain were interchanged, one term 6 of domain relates with two different values of range,
x = 6, y = 2.5
x= 6, y = 3
Since, a term of domain can't have two different values in range,
Therefore, interchanged relation will not be a function.

The length of a rectangle
is 4 meters less than twice the width.
If the area of the rectangle is 240 square meters,
The width is
meters.
The length IS
meters.
Answer:
length is 20 meters
width is 12 meters
Step-by-step explanation:
x = length
y = width
x = 2y - 4
x×y = 240
using the first equation as substitute in the second equation we get
(2y - 4)×y = 240
2y² - 4y - 240 = 0
the solution to such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
here we are going for y instead of x, but it is the same principle.
a = 2
b = -4
c = -240
y = (4 ± sqrt(16 - 4×2×-240))/4 = (4 ± sqrt(16 + 1920))/4 =
= (4 ± sqrt(1936))/4 = (4 ± 44)/4 = (1 ± 11)
y1 = 1 + 11 = 12
y2 = 1 - 11 = -10
negative side lengths don't make any sense, so, y = 12 meters remains.
x = 2y - 4 = 2×12 - 4 = 24 - 4 = 20 meters
Please help! What is |x-3|=9
Answer:
x = 12 or x = -6
Step-by-step explanation:
Solve for x over the integers:
abs(x - 3) = 9
Split the equation into two possible cases:
x - 3 = 9 or x - 3 = -9
Add 3 to both sides:
x = 12 or x - 3 = -9
Add 3 to both sides:
Answer: x = 12 or x = -6

What is the average rate of change over the
interval [0.75, 1.125]? Explain the meaning
of the average rate of change.
Answer:
The average rte of change = 6
2) The average rate of change over an interval is the ratio of the total change in the determinate variable or function (values of the output of the function) to the change in the indeterminate variable (values of the input of the function)
Step-by-step explanation:
1) The average of change of the function is found as follows;
At x = 0.75, y = -0.5, at x = 1.125, y = 1.75
Therefore, the average rate of change = (1.75 - (-0.5))/(1.125 - 0.75) = 6
2) The average rate of change over an interval on a graph or of a curve is found by dividing the difference between the y-coordinate values of the two points on the graph by the difference of the x-coordinate values of the two points.
