Subtract 10 from both sides:
3x < -9
Divide both sides by 3:
X < -3
Since x needs to be less than -3 the greatest internet would be -4

For what values (cases) of the variables the expression does not exist: a/2x−4
Answer:
x=2
Step-by-step explanation:
Given the expression: [tex]\dfrac{a}{2x-4}[/tex]
The expression is undefined or "does not exist" when the value of the denominator equals zero.
Therefore, set the denominator of the function equals to zero to find the values at which it does not exist.
2x-4=0
2x=4
x=2
Therefore, at x=2, the function is undefined.

Answer:
a) f(x) = x² -9
function is an even function
b) g(x) = |x -3|
function is an even function
c) f(x)= x / x²-1
function is odd function
d) g(x) = x + x²
Given function is not an even not odd function
This function is neither even or odd
Step-by-step explanation:
Explanation:-
a) Given f(x) = x² -9
Even function
If f(-x) = f(x) , then the function is even function.
f(-x) = (-x)² -9
= x² -9
= f(x)
f(-x) = f(x)
∴ Given function is an even function
b)
Given g(x) = |x -3|
Even function
If g(-x) = g(x) , then the function is even function.
g(-x) = |-(x-3)|
= |x-3|
g(-x) = g(x)
∴ Given function is an even function
c)
odd function
If f(-x) =- f(x) , then the function is odd function.
f(-x) = [tex]f(-x) = \frac{-x}{(-x)^{2}+1 } = \frac{-x}{x^{2}+1 } = - f(x)[/tex]
= -f(x)
f(-x) = -f(x)
∴ Given function is odd function
d)
If g(-x) = g(x) , then the function is even function.
g(x) = x + x²
g(-x) = -x + (-x)²
= - (x - x²)
This is not either even or odd function
∴ Given function is neither function
a) f(x) = x² -9
function is an even function
b) g(x) = |x -3|
function is an even function
c) f(x)= x / x²-1
function is odd function
d) g(x) = x + x²
Given function is not an even not odd function
This function is neither even or odd
Here, we have,
a) Given f(x) = x² -9
Even function
If f(-x) = f(x) , then the function is even function.
f(-x) = (-x)² -9
= x² -9
= f(x)
f(-x) = f(x)
∴ Given function is an even function
b)
Given g(x) = |x -3|
Even function
If g(-x) = g(x) , then the function is even function.
g(-x) = |-(x-3)|
= |x-3|
g(-x) = g(x)
∴ Given function is an even function
c)
odd function
If f(-x) =- f(x) , then the function is odd function.
f(-x) = -x/(-x)²-1
= -f(x)
f(-x) = -f(x)
∴ Given function is odd function
d)
If g(-x) = g(x) , then the function is even function.
g(x) = x + x²
g(-x) = -x + (-x)²
= - (x - x²)
This is not either even or odd function
∴ Given function is neither function.

Step-by-step explanation:
)) Devon jarred 15 liters of jam after 3 days. How much jam did Devon jar if she spent 4 days
making jam? Assume the relationship is directly proportional.
Answer:
20 liters
Explanation:
To find out how much jam Devon would jar if she spent four days making jam, we must first find out how much jam she makes in one day. In order to do that, we must divide how many liters of jam she makes in three days by the amount of days it took her to make it (three days).
15 liters ÷ 3 days = 5 liters per day
So, Devon jars 5 liters of jam per day.
Now that we found out how much jam she makes in a day, let's find out how much jam she makes in four days. To do that, we must multiply the amount of jam she makes in a day by four days.
5 liters × 4 days = 20 liters
Therefore, Devon will jar 20 liters of jam if she spends four days making jam.

Based on the given information in the problem, 18 is found to be 75% of 24.
Step-by-step explanation:
In order to solve this problem, we must first know what we are being asked to do. In the problem, we are asked to find what percent of 24 is 18. We can find this percentage by dividing. We will divide 24 by 18.
18 ÷ 24 = 0.75
Now, we multiply this number by 100 to get the percent.
0.75 × 100 = 75
So, 18 is 75% of 24.

The approximate area of the unshaded region under the standard normal curve is 0.8641.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have to find the area under the standard normal curve equals the z probability.
So, P = 1 - P(1 < z <2)
P = 1 - [ P(z<2)- P(z<1)]
As, the standard normal probability
P (z<1)= 0.8413
P(z<2) = 0.9772
So, P(1 < z <2)
= 0.9772 - 0.8413
= 0.1359
and, P = 1 - P(1 < z <2)
= 1 - 0.1359
= 0.8641

c) A shopkeeper made a loss of Rs 20 when he sold a bag at 20% discount. If he had sold it at 10% discount, he would have gained 8%. Find the marked price of the bag.
help!!
Answer: Marked price Rs. 600
Step-by-step explanation:
Let M be the marked price
1) When shop keeper sold at 20% discount, ie. SP = 0.8M
CP - SP = 20
CP = 20 + SP
CP = 20 + 0.8M
2) When shopkeeper sells at 8% discount, he makes a profit of 10%
SP = 0.9M/1.08
Equating 1 and 2, we get
20 + 0.8M = 0.9M/1.08
21.6 + 0.864M = 0.9M
0.036 M = 21.6
M = 21.6 / 0 036

[tex]\Large\fbox{\color{purple}{ SOLUTION }}[/tex]
let M, S and C be the mark price, selling price & cost price respectively.
1) when shopkeeper sells at 20% discount then he suffers a loss of rupees 20 then we have :-

term?
Answer:
The fifth term is 27
Step-by-step explanation:
Given:
[tex]T_1 = 1[/tex]
[tex]T_2 = 3[/tex]
Required
What is the fifth term?
Using the condition stated in the question;
[tex]T_5 = T_4 * T_3[/tex]
The values of [tex]T_4\ and\ T_3[/tex] are not known; so, we need to solve for both of them
[tex]T_3 = T_2 * T_1[/tex]
Substitute [tex]T_1 = 1[/tex] and [tex]T_2 = 3[/tex]
[tex]T_3 = 1 * 3[/tex]
[tex]T_3 = 3[/tex]
[tex]T_4 = T_2 * T_3[/tex]
Substitute [tex]T_2 = 3[/tex] and [tex]T_3 = 3[/tex]
[tex]T_4 = 3 * 3[/tex]
[tex]T_4 = 9[/tex]
Recall that
[tex]T_5 = T_4 * T_3[/tex]

Currently Jacobs mother is three more than nine times—
PLEASE HELP!
Answer:
Jacob's age = 4 years
Mother's age = 39 years
Step-by-step explanation:
Current year:
Mother's age = m
Jacob's age = j
m = 9j + 3 ------(I) {condition 1}
In 11 year,
Mother's age = m + 11
Jacob's age = j + 11
From condition 2,
m + 11 = 3(j +11) + 5
m + 11 = 3j + 3*11 + 5
m +11 = 3j + 33 + 5
m + 11 = 3j + 38
Subtract 11 from both sides,
m = 3j + 38 -11
m = 3j + 27 --------------(II)
Linear equations:
m = 9j + 3 ----------(I)
m = 3j + 27 --------(II)
Substitute m = 9j + 3 in equation (II)
9j + 3 = 3j + 27
9j = 3j + 27 - 3
9j = 3j + 24
Subtract 3j from both sides,
9j - 3j = 24
6j = 24
Divide both sides by 6,
j = 24/6
j = 4
Jacob's age = 4 years
Mother's age = 9*4 +3 = 36 + 3 = 39 years

Answer: B
Step-by-step explanation:
You are given the function
p(x) = √5x+7
Let p(x) = y then,
Y = √5x+7
To find the inverse of a function, you need to interchange x and y and make y the subject of formula. That is,
X = √5y+7
Square both sides
X^2 = 5y + 7
Make y the subject of formula
5y = x^2 - 7
Y = ( x^2 - 7 ) / 5

Answer:
Complementary angles are angles that add up to 90°. Supplementary angles add up to 180°.
Therefore, it's really easy to simply subtract the values that are less than 90 from 90 to receive the complement for those angles, but if it is above 90, subtract the number from 180. Therefore, your answers are as follows:
1. 54° and 144°
Complement: 90 - 36 = 54
Supplement: 180 - 36 = 144
2. 85° and 175°
Complement: 90 - 5 = 85
Supplement: 180 - 5 = 175
3. 20° and 110°
Complement: 90 - 70 = 20
Supplement: 180 - 70 = 110
4. 61° and 151°
Complement: 90 - 29 = 61
Supplement: 180 - 29 = 151
5. 40.8° and 130.8°
Complement: 90 - 49.2 = 40.8
Supplement: 180 - 49.2 = 130.8
6. 12°
Complement: 90 - 168 = -78 (negative angles do not work)
Supplement: 180 - 168 = 12
7. 79° and 169°
Complement: 90 - 11 = 79
Supplement: 180 - 11 = 169
8. 90 - 2x and 180 - 2x
Complement: 2x + (something) = 90 → 90 - 2x
Supplement: 180 - 2x
The measure of b is..
Answer:
b =21
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20^2 + b^2 = 29^1
400 + b^2 =841
Subtract 400 from each side
b^2 = 441
Take the square root of each side
sqrt(b^2) = sqrt(441)
b =21
Answer:
b = 21
Step-by-step explanation:
Ok so solving this is actually really simple.
We need to use the Pythageorum Theorum formula which is [tex]a^2+b^2=c^2[/tex].
So we already know the c and b which are 29 and 20 and we are trying to find b or a in the formula so.
We have to plug the numbers 29 and 20 into the formula and do the steps which is to sqaure them. So 29 and 20 squared are 841 and 400.
So we have to plug those numbers into the formula and it looks like this now [tex]a^2+400=841[/tex]. So now we have to get a squared alone and to do tha we subtract 400 from 841 which is 441. So now to find a we have to find the square root of a and 441 which is a and 21 so b is 21.
