Answer:
Domain: x>-3 Range: y [tex]\geq[/tex]-5
Step-by-step explanation:
The domain at the left has an open circle, meaning it is not uncluded in the domain. The domain would start from there, not including -3, and go on towards positive infinity. The range, at its lowest starts at -5, including negatove 5, since it is a closed circle, and goes up from there.

Share £360 into the ratio 3:2:1
Answers
Answer:
£180, £120 and £60.
Step-by-step explanation:
The number of parts = 3 + 2 + 1 = 6.
360 / 6 = 60, so the shares are:
3*60 = 180
2*60 = 120
1 * 60 = 60.
The distribution of £360 in the ratio of 3:2:1 will be £180, £120 and £60.
What is a ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
The number of parts = 3 + 2 + 1 = 6.
360 / 6 = 60, so the shares are:
3 x 60 = 180
2 x 60 = 120
1 x 60 = 60.
Hence the distribution of £360 in the ratio of 3:2:1 will be £180, £120 and £60.

Use absolute value notation to represent the distance between x and 8 is no more than 4
Answers
Between x and 8: x-8
The distance between x and 8: | x-8 |
“is no more than” means it can be that or be less than that, so use ≤
The distance between x and 8 is no more than 4
| x-8 | ≤ 4
| x - 8 | ≤ 8 will be the absolute value notation to represent the distance between x and 8 is no more than 4.
What is absolute value?Absolute values are the value of any digit without considering the sign.
So all negative values will be considered positive for absolute value.
For example, the absolute value of -2 will be 2 and the absolute value of -7 will be 7.
Given that,
Distance between x and 8
Now,
If x < 8 then x - 8 will negative and if x > 8 then it will positive.
So we need to use the mode function.
So,
| x - 8 | is distance between x and 8
Now it is no more than 4 so it is less than and equal to 8.
So,
| x - 8 | ≤ 8
Hence "| x - 8 | ≤ 8 will be the absolute value notation to represent the distance between x and 8 is no more than 4".

A company offering short term loans agrees to lend Nick $1,200. The amount (plus interest) is repayable in one year, and the interest rate is 12% per month. What is the total amount that must be repaid?
Answers
Answer:
$2,928 in 1 year
Step-by-step explanation:
Amount lent = $1,200
Monthly interest rate = 12%
Period = 12 months
Interest accrued = Amount lent * Monthly interest rate * Period
Interest accrued = $1,200 * 12% * 12
Interest accrued = $1,200 * 1.44
Interest accrued = $1,728
Amount repaid = Amount lent + Interest accrued
Amount repaid = $1,200 + $1,728
Amount repaid = $2,928

Pick 2 points on the line and find the “rise” and “run” between them.
To get from (0,3) to (4,0), you’d need to go “down 3” and “right 4”.
Since the slope is “rise over run” and a rise of “down 3” means a rise of “-3”, your slope is -3/4.
Next find the y-intercept: (0,3)
Use the 3 as your b-value for the slope-intercept form.

P____Q____R
PR= PQ+ QR

14x-13= 11x – 1
14x – 11x = 13–1
3x = 12
x= 12/ 3
x= 4
PR= 14x – 13 = 14 (4) – 13 = 18 – 13= 5
If you want (PQ , QR ) this is the solution

r³ = 27
r = ³√27
r = 3

The slope of the line passing through the points (-6, -8) and (2, 8) is 2.
Used the formula for the slope of the line passing through the points
(x₁ , y₁) and (x₂, y₂) would be,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Given that,
A coordinate plane with a straight line passing through the points (-6, -8) and (2, 8).
By using the above formula, the slope of the line is,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
[tex]m = \dfrac{(8 - (-8))}{(2 - (- 6))}[/tex]
[tex]m = \dfrac{(8 + 8)}{(2 + 6)}[/tex]
[tex]m = \dfrac{(16)}{(8)}[/tex]
