Step-by-step explanation:
Can't compare f(x) = x+1 when x<=0 with g(x)=x+1 when x>-1 since the functions are equal between -1<x<=0.
Compare f(x) = 3 when x>0 with g(x)=x+1 when x>-1
g(x) can't be greater than or equal to f(x):
g(x)<f(x)
x+1<3
x+1-1<3-1
x<2 and x>0 ==> 0<x<2
0<x<2 ==> (0, 2) ==> x is between 0 and 2 not including 0 and 2.
Compare f(x) = x+1 when x<=0 with g(x)=2x when x<=-1. Both equations have common x-values at x<=-1.
g(x)<f(x)
2x<x+1
2x-x<x-x+1
x<1 and x<=-1 ==> x<=-1
x<=-1 ==> (-∞, -1] ==> x is between -∞ and -1 not including -∞ but including -1.

Mrs Rama uses three types of fruit juice for a party. The ratio of the amount of watermelon juice to the amount of apple juice is 4: 9. The Ratio of the amount of apple juice to the amount of orange juice is 27: 14. Find the ratio of the amount of watermelon juice to the amount of apple juice to the amount of orange juice in its simplest form
Answers
the ratio of the amount of watermelon juice to the amount of apple juice to the amount of orange juice in its simplest form is 12 : 27 : 14.
The ratio of the amount of watermelon juice to the amount of apple juice = 4 : 9
This can also be written as:
4 × 3 : 9 × 3
12 : 27
The ratio of the amount of apple juice to the amount of orange juice = 27 : 14
Now, the ratio of the amount of watermelon juice to the amount of apple juice to the amount of orange juice will be:
Ratio = 12 : 27 : 14
Therefore, the ratio of the amount of watermelon juice to the amount of apple juice to the amount of orange juice in its simplest form is 12 : 27 : 14.

6. a. $250. b. $200. c. $0. d. $490.

8. a. $250. b. $800. c. $1250. d. $2300.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item 5, the amount is less than $5,000, hence there is a single commission of 5%, as follows:
0.05 x 4000 = $200.
Hence the amounts are:
a. $200. b. $0. c. $0. d. $200.
For item 6, the commissions are divided as follows:
5% of the first $5,000: 0.05 x 5000 = $250.8% of the next $3,000: 0.08 x 3000 = $240.For a total of $490, as 250 + 240 = 490.
Hence the amounts are:
a. $250. b. $200. c. $0. d. $490.
For item 7, the commissions are divided as follows:
5% of the first $5,000: 0.05 x 5000 = $250.8% of the next $10,000: 0.08 x 10000 = $800.10% of the final $3,000: 0.1 x 3000 = $300.For a total of $1,350, as 250 + 800 + 300 = 1350.
Hence the amounts are:
a. $250. b. $800. c. $300. d. $1350.
For item 8, the commissions are divided as follows:
5% of the first $5,000: 0.05 x 5000 = $250.8% of the next $10,000: 0.08 x 10000 = $800.10% of the final $12,500: 0.1 x 12500 = $1,250.For a total of $2,300, as 250 + 800 + 1250 = 2300.

When multiplying a number by 10 move the decimal to the right. When multiplying a number by .01 move the decimal to the left. Why
Answers
The reason why multiplying a number by 10 moves the decimal to the right is because the number is increasing. When the decimal moves left when multiplied by 0.01, the number is decreasing.
What happens when you multiply by powers of 10?When you multiply by powers of 10 which are positive, the number that is being multiplied will see its decimal move to the right. This is to show that the number is now increasing in value.
When you multiply by 0.01 however, the number will decrease and so the decimal will have to move left to show that the value of the number has decreased. For instance, 50 x 0.01 becomes 0.5.

a) reflection in the line x = -2 is P'Q'R' is shown.
b) The coordinates of image P'Q'R' are
(-12, 0), (-18, -9), R(-5,-5) respectively.
What is defined as the dilation?Dilation is a transformation that allows you to resize an object. Dilation is a technique for making objects larger or smaller. This transformation yields an image that is identical to the original shape. However, there is a size difference in the shape.Part a) reflection in the line x = -2
When the triangle PQR with the coordinates P(-4, 0), Q(-6, -3), and R(-5,-5) made a reflection along the x = -2, the coordinates of the image are obtained as;
See the graph; image triangle P'Q'R';
P' = (0, 0)
Q' = (2, -3)
R' = (1, -5)
Part b) dilation with scale factor of 3 using (-1, -4) as the center.
Let the coordinates are;
(x, y) ---> (kx, ky); where k is the scale factor i.e, 3.
This can be written as; (3x, 3y).
For the point P(-4, 0).
The image of P' = (-4×3, 0×3) = (-12, 0)
For the point Q(-6, -3)
The image of Q' = (-6×3, -3×3) = (-18, -9)
For the point R(-5,-5)
The image of P' = (-5×3, -5×3) = (-15, -15)

Answers
The price of 1 hamburger is $4.6 and 1 fish sandwich is $5.2
Calculations and ParametersLet 1 hamburger be x
Let 1 fish sandwich be y
Thus, we have:
3x + 2y= 24.20...... eq 1
4x + y= 23.60........ eq 2
Let's use the substitution method here:
Make y the subject formula in eq 2
y= 23.60 - 4x......... eq 3
Put the value of y into eq 1
3x + 2(23.60 - 4x) = 24.20
3x + 47.2 - 8x = 24.20
-5x + 47.2 = 24.20
Exchange values to eliminate the negative symbol
5x = 47.2- 24.20
5x= 23
x= 4.6
Put the value of x into eq 3
23.60- 4(4.6)
y= 23.60-18.4
y= $5.2
Therefore, the price of 1 hamburger is $4.6 and 1 fish sandwich is $5.2

Probability of 0.79 and would warrant a refund
Probability of 0.21 and would warrant a refund
Answers
The probability of 0.21 and would not warrant a refund. Therefore, option A is the correct answer.
Given that, mean depth =0.98 mm, standard deviation =0.35 mm.
What is a standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
We are given that the distribution of tire tread is a bell-shaped distribution that is a normal distribution.
Formula: [tex]Z_{score}=\frac{x-\mu}{\sigma}[/tex]
Here, P(depth less than 0.70 mm)
P(x < 0.70)
Then, P(x < 0.70)=P(z<(0.70-0.98)/0.35)
=P(z<(-0.8)
Calculating from the normal z table, we get P(z<(-0.8)=0.212
≈0.21
Thus, the probability of 0.21 and would not warrant a refund. Therefore, option A is the correct answer.

Answers
The solution for the equation x² – 4x – 45 = 0 is (x – 9) (x + 5)
Given,
Quadratic equation = x² – 4x – 45
We can solve this by using quadratic formula.
Equations of the form ax² + bx + c = 0 can be solved using quadratic formula.
Here the equation is in the form of above mentioned:
x² – 4x – 45 = 0
Quadratic formula = [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]
Substitute the values in the formula,
x = [tex]\frac{-(-4)(+-)\sqrt{(-4)^{2}-4(-45) } }{2}[/tex]
x = [tex]\frac{4(+-)\sqrt{16 -4(-45)} }{2}[/tex]
x = [tex]\frac{4(+-)\sqrt{16+180} }{2}[/tex]
x = [tex]\frac{4(+-)\sqrt{196} }{2}[/tex]
x = [tex]\frac{4(+-)14}{2}[/tex]
Now, solve the equation for:
x = [tex]\frac{4+14}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9
Next, solve the equation for:
x = [tex]\frac{4-14}{2}[/tex] = [tex]\frac{-10}{2}[/tex] = -5
According to ax² + bx + c = a(x - x₁) (x - x₂),
Here, x₁ is 9 and x₂ is -5
So,
x² - 4x - 45 = ( x - 9) (x - (-5))
That is,
x² - 4x - 45 = (x - 9) (x + 5)

The "center-radius" form is
(x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r
The graphed circle has its center at (3,1) and a radius of 2. Putting these numbers into the above form gives the equation
(x -3)² +(y -1)² = 4 . . . . center-radius form
Expanding the parentheses, we get
x² -6x +9 +y² -2y +1 = 4
Subtracting 4, and putting in general form, the equation becomes ...
x² +y² -6x -2y +6 = 0 . . . . general form
a graph (inclusive of a sequence of one or greater factors, strains, line segments, curves, or areas) that represents the variant of a variable in assessment with that of one or greater other variables. the gathering of all factors whose coordinates fulfill a given relation (inclusive of a function)
A graph of a function is a unique case of a relation. within the modern foundations of mathematics, and, generally, in set theory, a function is clearly same to its graph. however, it is regularly useful to look functions as mappings, which consist no longer best of the relation among enter and output, but additionally which set is the domain, and which set is the codomain. as an instance, to mention that a characteristic is onto (surjective) or not the codomain have to be taken under consideration
