The answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.
We have an expression of inequality:-
(-1/2)p < -16
p > 32 . . . . . . multiply by -2; this reverses the inequality symbol
The open circle will be at 32; the line will be shaded for higher values (to the right).
Hence the answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.

5) Find the x-intercept and the y-intercept of the equation: 8x - y = -24.
Answer:
First we have to turn it into slope intercept form which is y = mx + b.
we need to isolate y. To do this, we have to subtract 8x from both sides to get
-y = -8x - 24
-25 is the y intercept and -8 is the slope.
Step-by-step explanation:
What is the slope of the line passing through the points (4, 5) and (0, -7)? Show all your work.
Answer:
slope = 3
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 5 ) and (x₂, y₂ ) = (0, - 7 )
m = [tex]\frac{-7-5}{0-4}[/tex] = [tex]\frac{-12}{-4}[/tex] = 3

Answers: 585, 587, and 593
Basically everything except 599
==============================================================
Why?
Those answers in bold are closer to 590 than they are to 580 or 600. When rounding to the nearest ten (not tenth) we look at the units digit. If it is 5 or larger, then we bump the tens digit up by 1 and replace the units digit with a 0.
This explains why 585 and 587 round to 590
The number 599 rounds to 600 for similar reasoning, but we cross it off the list since we want 590.
The number 593 rounds to 590 because the 3 in the units digit isn't 5 or larger. So we just replace the 3 with 0 and keep everything else as is.

3. the bike Ville is more expensive in everything
Using Average, the prices of bicycles at two stores are compared.
What is average?Average is the" sum of observations divided by total number of observations".
According to the question,
The price of bicycles at two stores are shown.
Bikeville: 140 160 800 235 250 450 80 115 220 250 96 290
Discount Bicycles: 50 180 300 110 120 150 155 285 120 200 70 175 95
Average of bikeville = [tex]\frac{sum of observations}{Total number of observation}[/tex]
= 140 + 160 + 800 + 235 + 250 + 450 + 80 + 115 + 220+250+96+29
= 3086
Average of bikeville= 3086/12
= 257.167
Average of Discount of bicycles:
( 50 +180+100+110+120+150+155+285+
120+150+155+285+120+200+70+175+95) =2720
= 2720/15
=181.33
Average of Discount of bicycles is 181.33.

A) $7,962.65 B) $8,625.82
C) $8,287.61 D) $7,650.44
Answer:
$7650.44
Step-by-step explanation:
Annual interest rate = 4.02%
but compound 4 times per year, means quarterly compound
quarterly interest rate = 4.02%/4 = 1.005%
Account balance = 4734 * (1.01005)^48 [compound 4 times a year for 12 years]
