3/8 divided by 2/5??
Answer:
15/16
Ste
Step-by-step explanation:
Keep, Change, Flip.
(1) Keep the first fraction, 3/8.
(2) Change the sign from a division sign to a multiplication sign.
(3) Flip the last fraction, 2/5 --> 5/2.
(4) Multiply across.
3/8 x 5/2= 15/16
The 3/8 divided by 2/5 is equal to 15/16.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
To divide 3/8 by 2/5:
(3/8) ÷ (2/5) = (3/8) × (5/2)
Now, let's multiply the numerators and denominators:
(3 × 5) / (8 × 2) = 15/16

The table shows the outputs, y, for different inputs, x:
Input 2 4 6 8
Output
(y)
1 2 3 4
Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) = 3x - 10. Which relation has a greater value when x = 8? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 80? (5 points)
(10 points)
Answer:
A: The data does represent a function because there are no repeating x values. a function can have repeating y values but cannot have repeating x values. Also, there is one value of y for every value of x.
B: f(x)=1/2x
f(x)= 3x-10
f(8)=1/2(8) ----> 4
f(8)=3(8)-10 ----> 14
f(x)=3x-10 has a greater value when x=8
C: f(x)=1/2x
f(x) = 80
80=1/2x
80*2=x
x=160
Step-by-step explanation:
The data in the table is a function. The relation has f(x) = 3x - 10 has greater value when x = 8. And the value of x is 30 when f(x) = 80.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Part A :
The table has the data values,
x : 2 4 6 8
y : 1 2 3 4
The given data represents a function, because elements in the domain (2, 4, 6 and 8) has only one image in the Range (1, 2, 3 and 4).
Part B :
f(x) = 3x - 10
x = 2, then f(x) = y = -4
x = 4, then f(x) = y = 2
x = 6, then f(x) = y = 8
x = 8, then f(x) = y = 14
The relation f(x) = 3x - 10 has the greater value when x = 8.
Part C :
f(x) = 80
3x - 10 = 80
3x = 80 + 10
3x = 90
x = 90 / 3
x = 30
Hence the relation in the table is a function. The second relation f(x) = 3x - 10 has the greater value when x = 10 after computing the values of both the relations.

slope-intercept from two points (4,-8) and (8,5)
Here you go :)
Slope is equal to the change in y over the change in x or rise over run:
m = change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise):
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope:
m=5−(−8)/8−(4)
Simplify:
m=13/4
Substitute the value of m into the slope-intercept form of the equation, y = m x + b :
y=(13/4)x+b
Substitute the value of x into the slope-intercept form of the equation, y = m x + b .
y = ( 13/ 4 ) ⋅ ( 4 ) + b
Substitute the value of y into the slope-intercept form of the equation, y = m x + b .
− 8 = ( 13/ 4 ) ⋅ ( 4 ) + b
Rewrite the equation as ( 13 4 ) ⋅ ( 4 ) + b = − 8 .
( 13/ 4 ) ⋅ ( 4 ) + b = − 8
Cancel the common factor.
13/ 4 ⋅ 4 + b = − 8
Rewrite the expression.
13 + b = − 8
Move all terms not containing b to the right side of the equation.
b = − 21
The values of the slope and y-intercept are m = 13 4 and b = − 21 .
m = 13 4
b = − 21

A) The three angles could be 30°, 30°, and 30° B) The three angles could be 30°, 60°, and 90° C) The three angles could be 30°, 70°, and 80° D) The three angles could be 30°, 30°, and 120°
Answer:
Answer C
Step-by-step explanation:
This is because acute triangles have angles that are under 90 degrees and Option A would be true to what you are trying to make false and B & D are false because they have angles that go over 90 degrees.
The other statements that provide contradiction to the given expression are option (B) and (C).
What is a acute triangle?An elementary polygon having three sides and three vertices is a triangle. There are three internal angles since it has three sides. An acute angle is one that ranges in measurement from 0° to 90°. A form of triangle called an acute triangle has acute angles at each of its three internal angles.
In the option (A),
the three angles could be 30°, 30°, and 30°.
These angles contradict the basic property of triangle.
Which is sum of all the triangles are 180°.
In the option (B),
the three angles could be 30°, 60°, and 90°.
The above angles hold the property of an acute triangle.
In the option (C),
The three angles could be 30°, 70°, and 80°.
The above angles also hold the property of an acute triangle.
In the option (D),
The three angles could be 30°, 30°, and 120°.
Angle 120° greater than 90°.
This statement contradicts the basic property of an acute triangle.
Therefore, the other statements that provide contradiction to the given expression are option (B) and (C).

Given h(x)=-x-4h(x)=−x−4, solve for xx when h(x)=9h(x)=9.
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
Given [tex]h(x)=-x-4[/tex], solve for x when [tex]h(x)=9h(x)=9[/tex].
First we need to figure out what number multiplied by 9 is equal to 9. This number is 1. [tex](1*9=9)[/tex]
Therefore, we know that h(x) should be equal to 1 in order for 9 times h(x) to equal 9.
Create an equation where h(x) = 1.
[tex]h(x)=1 \\ (-x-4)=1[/tex]Solve this equation by adding 4 to both sides of the equation.
[tex]-x=5[/tex]Divide both sides of the equation by -1 to isolate x.
[tex]x=-5[/tex]Check your answer by substituting -5 for x back into the equation to make sure h(x) = 1.
[tex]-(-5) - 4 = 1[/tex]If [tex]h(x)=1[/tex], then the statement [tex]9h(x) =9[/tex] is true, verifying our answer for x is correct.

Answer:
x = 6°
y = 15°
Step-by-step explanation:
90 + 6y = 180 (linear pair, supplementary)
6y = 90 (180 - 90)
y = 15°
6y and 5x + 60 are corresponding angles. Corresponding angles are equal
Hence:
6y = 5x + 60
Sub y = 15° into equation
90 = 5x + 60
90 - 60 = 5x
5x = 30
x = 6°

x/16- (x+2)/8=2 pls help, need answer soon.
Answer:
x = -36
Step-by-step explanation:
Step 1: Write equation
x/16 - (x + 2)/8 = 2
Step 2: Solve for x
Multiply both sides by 16: x - 2(x + 2) = 32Distribute -2: x - 2x - 4 = 32Combine like terms: -x - 4 = 32Add 4 to both sides: -x = 36Divide both sides by -1: x = -36Step 3: Check
Plug in x to verify it's a solution.
-36/16 - (-36 + 2)/8 = 2
-9/4 - -34/8 = 2
-9/4 + 17/4 = 2
8/4 = 2
2 = 2

Answer:
Step-by-step explanation:
Given the inequality −14x+6≥14, we are to find the range of x that will make the inequality true.
Given −14x+6≥14
Subtract 6 from both sides.
−14x+6-6≥14-6
-14x≥8
-7x≥4
Multiply both sides by -1
-(-7)x≤-4
7x ≤ -4
x≤-4/7
This shows that the values of x is always less than or equal to -0.57
Hence the values less tan the value of x in the inequality are -36, -32 and -16

Exact value of tan(m + n)
Solution:
Find m and n:
