Graphs are used to show the relationship between two variables. In the given graph, as the value of x increases, the value of y decreases.
Given that:
[tex]y = \frac{10}{x}[/tex]
The above function is an inverse function.
This means that:
As the value of x increases, the value of y decreases
Take for instance:
[tex]x= 1[/tex]
[tex]y = \frac{10}{1} = 10[/tex]
Now, [tex]x = 2[/tex]
[tex]y = \frac{10}{2} = 5[/tex]
Notice that:
As x increases from 1 to 2, the corresponding values of y decreases from 10 to 5
Hence, (b) is correct

An unknown polynomial is added to the expression -3x^3+2x-5 and the resulting sum is 4x^3+7x^2-3. what is the unknown polynomial?
Answers
Answer:
7x³ + 7x² + 2x - 8
Step-by-step explanation:
Let the unknown polynomial be a
a + -3x³ + 2x - 5 = 4x³ + 7x² - 3
a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)
a = 4x³ + 7x² - 3 + 3x³ + 2x - 5
a = 7x³ + 7x² + 2x - 8

find slope that is perpendicular to the line 4−2=12 ?
Answers
Answer:
m = -1/2
Step-by-step explanation:
4 − 2 = 12
= −2 = 12 − 4
= = (12 − 4) ÷ (−2)
= = 2−6
So, the slope is 2.
Now, keep this rule in mind: the product of a slope of two perpendicular lines will be -1.
Thus, the slope of the line that is perpendicular to this line is -1/2
Find the lest number which is exactly divisible by 36 & 90 Maths
Answers
Answer:
180Step-by-step explanation:
You need to find the HCF of 36 and 90.
Prime factors of each:
36 = 2*2*3*390 = 2*3*3*5HCF includes all prime factors of both numbers:
HCF(36, 90) = 2*2*3*3*5 = 180To find the least number,
Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.
→ 36 = 2 × 2 × 3 × 3
→ 90 = 2 × 3 × 3 × 5
Then the required HCF will be,
→ 2 × 2 × 3 × 3 × 5
→ 180 (HCF)
Thus, 180 is the least number which is exactly divisible by 36 and 90.

please show work 7r + 21 = 49r
Answers
Answer:
1/2 = r
Step-by-step explanation:
7r + 21 = 49r
Subtract 7r from each side
7r-7r + 21 = 49r-7r
21 = 42r
Divide each side by 2
21/42 = 42r/42
1/2 = r
Answer:
r = 0.5
Step-by-step explanation:
First you need to isolate the r variable.
7r + 21 = 49r
-7r -7r
21 = 42r
Then Divide both sides by 42
0.5 = r
Now check your answer by inserting it back into the original equation.
7(0.5) + 21 = 49(0.5)
3.5 + 21 = 24.5
24.5 = 24.5
The equation is true so r = 0.5
sin(60-theta)sin(60+theta)
Answers
Step-by-step explanation:
[tex] \sin(60 - \theta) \sin(60 + \theta) \\ = \{ \sin(60) \cos( \theta) - \sin( \theta) \cos(60) \} \{ \sin(60) \cos( \theta) + \cos(60) \sin( \theta) \} \\ = \{ \frac{ \sqrt{3} }{2} \cos( \theta) - \frac{1}{2} \sin( \theta) \} \{ \frac{ \sqrt{3} }{2} \cos( \theta) + \frac{1}{2} \sin( \theta) \} \\ \\ [/tex]
from difference of two squares:
[tex]{ \boxed{(a - b)(a + b) = ( {a}^{2} - {b}^{2} ) }}[/tex]
therefore:
[tex] = \{ {( \frac{ \sqrt{3} }{2}) }^{2} { \cos }^{2} \theta \} - \{ {( \frac{ \sqrt{3} }{2} )}^{2} { \sin }^{2} \theta \} \\ \\ = \frac{3}{4} { \cos }^{2} \theta - \frac{3}{4} { \sin}^{2} \theta[/tex]
factorise out ¾ :
[tex] = \frac{3}{4} ( { \cos }^{2} \theta - { \sin}^{2} \theta) \\ \\ = { \boxed{ \frac{3}{4} \cos(2 \theta) }}[/tex]

On a number line what is the distance between -3/2 and 6?
Answers
Answer:
7.5 unitsStep-by-step explanation:
The distance is always positive and is same as the absolute value of subtraction of the two numbers on the line.
This can be shown as:
|-3/2 - 6| = |-1.5 - 6| =|-7.5| = 7.5or
| 6 - (-3/2)| = |6 + 1.5| = |7.5| = 7.5Answer:
15/2 or 7.5
Step-by-step explanation:
Distance = x_2 - x_1
Distance = 6 - (-3)/2
Distance = 6 + 3/2
Distance = 12 + 3/2
Distance = 15/2 or 7.5

there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?
Answers
Answer:6 students remaining
Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.
Students who gave speech yesterday:
2/3 of 45
= 30
Students left= 45-30 = 15
Students who gave speech today:
3/5 of 15
= 9
No. of who still haven’t give speech
= 15-9
= 6 students

To multiply numbers or expressions means that we calculate the product of the numbers or expressions. The value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]
Given that:
[tex]-0.5 \times (-0.4)[/tex]
Cancel out the negative signs
[tex]-0.5 \times (-0.4) = 0.5 \times (0.4)[/tex]
Using a calculator, we have:
