Step-by-step explanation:
The question is not properly presented; I will answer this with the following similar question.
[tex]h(x) = -\frac{1}{3}x^2 + 4[/tex] --- [tex]x \ne 2[/tex]
[tex]h(x) = -4[/tex] --- [tex]x= 2[/tex]
Required
[tex]h(-5)\ \&\ h(2)[/tex]
Calculating h(-5)
This implies that: x = -5
[tex]-5 \ne 2[/tex]
So, we make use of:
[tex]h(x) = -\frac{1}{3}x^2 + 4[/tex]
Substitute -5 for x
[tex]h(-5) = -\frac{1}{3} * (-5)^2 + 4[/tex]
[tex]h(-5) = -\frac{1}{3} * 25 + 4[/tex]
[tex]h(-5) = -\frac{25}{3} + 4[/tex]
Take LCM
[tex]h(-5) = \frac{-25+12}{3}[/tex]
[tex]h(-5) = -\frac{13}{3}[/tex]
Calculating h(2)
This implies that: x = 2
[tex]2 = 2[/tex]
So, we make use of:
[tex]h(x) = -4[/tex]
Substitute 2 for x
[tex]h(2) = -4[/tex]

-2 is an extraneous solution because it creates 0 in the denominator.
There is one acceptable solution to the equation
Step-by-step explanation:
x² + 5x + 6 = x² + 2x + 3x + 6
= x(x + 2) + 3(x + 2)
= (x + 2)(x + 3)
[tex]\frac{x}{x+2}+\frac{2}{x^{2}+5x+6}=\frac{5}{(x+3)}\\\\\frac{x}{x+2}+\frac{2}{(x+2)(x+3)}=\frac{5}{(x+3)}\\\\\frac{x*(x+3)}{(x+2)(x+3)}+\frac{2}{(x+2)(x+3)}=\frac{5*(x+2)}{(x+3)(x+2)}\\\\\frac{x^{2}+3x+2}{(x+2)(x+3)}=\frac{5x+10}{(x+3)(x+2)}\\\\[/tex]
x² + 3x + 2 = 5x + 10
x² + 3x - 5x + 2 - 10 = 0
x² - 2x - 8 = 0
x² + 2x - 4x - 8 = 0
x(x + 2) - 4(x + 2) = 0
(x + 2)(x - 4) = 0
x +2 = 0 or x - 4 = 0
x = - 2 or x = 4

Angle 2 and Angle 4 are same-side interior angles, which are supplementary.
(2x + 10) + (4x + 80) = 180
6x + 90 = 180
6x = 90
x = 15
Hope this helps!
Answer:
X = 15
Step-by-step explanation:
Angle 2 = Angle 3 since they are alternate angles
Now, angle 3 and 4 should add up to 180 since they are on a straight line
∴ (2x + 10) + (4x + 80) = 180
6x + 90 = 180
6x = 180 - 90
6x = 90
x = 15

• Shanna had $10 in her piggy bank and earned $10 each week in allowance.
• Shanna had $10 in her piggy bank and earned $5 each week in allowance.
• Shanna had $10 in her piggy bank and spent $5 each week on stickers.
• Shanna earns $10 each week.
Answer:
• Shanna had $10 in her piggy bank and earned $5 each week in allowance.
Step-by-step explanation:
Week 0 dollars = 10
This means Shanna had $10 her piggy bank before the week started
Week 2 dollars = 20
Her account has increased from 10 to 20 dollars in two weeks. This means she is earning
Amount earned per week = change in earnings / change in week
= 20 dollars - 10 dollars / Week 2 - week 1
= 10 dollars / 2 weeks
= 5 dollars per week
Amount earned per week = $5
Therefore,
• Shanna had $10 in her piggy bank and earned $5 each week in allowance

a. dilation
b. translation
c. reflection

e. none of these answers are correct
would it be best to go with b or e?
Answer:
b translation
Step-by-step explanation:
Dilation means that it gets bigger or smaller
translation means a shift
reflections means that it flips across a line of symmetry
rotation means that it rotates across a point
We shifted the figure down and to the right. It appears to be the same size and shape
I would go with a translation

If the product of roots of the equation given below is 4, then find the value of m.
Answer:
m=-2
Step-by-step explanation:
As the product of the roots of a quadratic equation is c/a in ax^2+bx+c=0
here a=2, b=+8, c=-m^3
Given c/a=4
-m^3/2=4
-m^3=8
m^3= -8
m=-2.
find the slope of the line for each pair of points (2, -10) (8, -16)
Answer:
-1
Step-by-step explanation:
We can use the slope formula since we are given two points
m = (y2-y1)/(x2-x1)
= (-16- -10)/(8-2)
= (-16+10)/(8-2)
= -6/6
= -1

△STR≅△LMN, SR=7b+8, and LN=11b−12. Find b and SR.
Answer:
b = 5
Step-by-step explanation:
△STR ≅ △LMN
This means the corresponding sides are equal.
SR and LN are corresponding sides.
SR and LN are equal.
The value of b is 5.
The value of SR is 43
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
△STR ≅ △LMN
This means the corresponding sides are equal.
SR = 7b + 8
LN = 11b − 12
SR and LN are corresponding sides.
SR and LN are equal.
So,
7b + 8 = 11b − 12
Subtract 7b on both sides.
8 = 11b - 7b - 12
Add 12 on both sides.
8 + 12 = 4b
20 = 4b
b = 20/4
b = 5
Now,
SR:
= 7b + 8
= 7 x 5 + 8
= 35 + 8
= 43
Thus,
The value of b is 5.
The value of SR is 43

Which of the following operations is true regarding relative frequency distributions? Multiple choice question. No two classes can have the same relative frequency. The relative frequency is found by dividing the class frequencies by the total number of observations. The sum of the relative frequencies must be less than 1. The sum of the relative frequencies is equal to the number of observations.
Answer:
The relative frequency is found by dividing the class frequencies by the total number of observations
Step-by-step explanation:
Relative frequency measures how often a value appears relative to the sum of the total values.
An example of how relative frequency is calculated
Here are the scores and frequency of students in a maths test
Scores (classes) Frequency Relative frequency
0 - 20 10 10 / 50 = 0.2
21 - 40 15 15 / 50 = 0.3
41 - 60 10 10 / 50 = 0.2
61 - 80 5 5 / 50 = 0.1
81 - 100 10 10 / 50 = 0.2
50 1
From the above example, it can be seen that :
two or more classes can have the same relative frequencyThe relative frequency is found by dividing the class frequencies by the total number of observations. The sum of the relative frequencies must be equal to one The sum of the frequencies and not the relative frequencies is equal to the number of observations.Let’s think about another type of scenario. What if you were told that a bracelet requires 10 beads and 10 minutes to make while a necklace requires 20 beads and takes 40 minutes to make. The craftsman has 1000 beads to work with and he has 1600 minutes in which to work. If a bracelet costs $5 and a necklace costs $7.50, what is the maximum revenue that the craftsman can take in?
Answer:
$425
Step-by-step explanation:
Let x represent the number of bracelets made and let y represent the number of necklace made.
Since the craftsman has 1000 beads to work with, hence:
10x + 20y ≤ 1000 (1)
Also, the craftsman has 1600 minutes, hence:
10x + 40y ≤ 1600 (2)
From ploting equations 1 and 2 on the geogebra online graphing, we can see that the solution to the problem is (40, 30).
Since the bracelet costs $5 and a necklace costs $7.50, hence the maximum revenue is:
Revenue = 5x + 7.5y = 5(40) + 7.5(30) = $425

Answer:
18c - 30d + 36
Step-by-step explanation:
To apply the distributive property, we must "distribute" (multiply) the outer term by the terms in the parentheses. In this case, the outer term is 6, and the inner terms are 3c, 5d, and 6. Then, if there's any like terms, you must combine them.
6(3c - 5d + 6)
(6 · 3c) + (6 · -5d) + (6 · 6)
18c + -30d + 36
As you can see, there's no like terms in this expression, so the equivalent expression to 6(3c - 5d + 6) is 18c + -30d + 36.

2r + st^2 - u, if r = 4, s = 6, t = 3, and u = 12
Answer:
320
Step-by-step explanation:
r = 4, so 2 x 4 = 8.
s = 6 and t = 3, so 6 x 3 = 18. 18 squared is 324.
u = 12, so 8 + 324 - 12, which equals 320.

b) There isn't enough information to determine which function has a steeper slope.
c) The functions ƒ(x) and g(x) have the same slope.
d) The function ƒ(x) has a steeper slope than g(x).
Answer:
d) The function ƒ(x) has a steeper slope than g(x)
Step-by-step explanation:
We are given that
[tex]f(x)=-2x-7[/tex]
The graph g(x) passing through the point (1.2,0) and (0,4).
Let
y=f(x)=-2x-7
Slope of function f(x)
[tex]m=\frac{dy}{dx}=-2[/tex]
Slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Using the formula
Slope of g(x)
[tex]m'=\frac{4-0}{0-1.2}[/tex]
[tex]m'=-3.33[/tex]
Slope of g(x)=-3.33<-2
Slope of f(x) is greater than slope of g(x).
Therefore, function f(x) has a steeper slope than g(x).

what amount of money is to be deposited in a bank to get RS 1225 in 9/2 year with the rate of intrest 5%

P×10×2
=1260
The amount of money that we need to deposit in the bank to get RS 1225 is RS 1100.03.
What is compound interest?Compound interest is applicable when there will be a change in principal amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount.
Suppose we need to deposit the P amount to get RS 1225
By compound interest formula,
1125 = P(1 + 0.05)^(9/2)
P = RS 1100.03
Hence "We need to deposit Rs. 1100.03 in the bank in order to receive Rs. 1225".
