Answer:
x ≤ -4
Step-by-step explanation:
The dot/filled-in circle is on -4, so that's where we get that part of the inequalityThe line is going to the left of -4 (going towards the negatives), so x is less than -4The dot/circle is filled in, which means it is an "or equal to" symbol (in our case it's less than or equal to)Put it all together: x ≤ -4I hope this helps!

HELPPPP PLZZZ
Answers
Answer: 252 dollars
Step-by-step explanation: the computer is 400$ and 400*0.3 is the 30% off. That makes 120, 400-120 is 280 and then the 10% off, 280*0.1=28. Last step is to do 280-28=252

James Bond is rappelling down a cliff face to infiltrate an enemy base, but there is a gust of wind, and he starts swinging side to side. If he makes a 45 m pendulum once you factor in the length of the rope, how long does it take for him to complete a full oscillation? He'll need to know this so that he can time his distraction of the guards
Answers
Answer:
13.46 s
Step-by-step explanation:
The time it takes James Bond to complete one full oscillation is the period of a pendulum of length, l which is, T = 2π√(l/g) where l = length of pendulum = length of rope = 45 m and g = acceleration due to gravity = 9.8m/s²
So, substituting the values of the variables into the equation, we have
T = 2π√(l/g)
= 2π√(45 m/9.8m/s²)
= 2π√(4.592s²)
= 2π × 2.143
= 13.46 s
So, it takes 13.46 s for him to complete one full oscillation.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-6x + 5y = 34
-6x - 10y = 4
Step 2: Rewrite Systems
-6x + 5y = 34
Multiply everything by -1: 6x - 5y = -34Step 3: Redefine Systems
6x - 5y = -34
-6x - 10y = 4
Step 4: Solve for y
Elimination
Combine 2 equations: -15y = -30Divide -15 on both sides: y = 2Step 5: Solve for x
Define equation: -6x - 10y = 4Substitute in y: -6x - 10(2) = 4Multiply: -6x - 20 = 4Add 20 on both sides: -6x = 24Divide -6 on both sides: x = -4the value of sqrt -4 is not -2 because? HELP

A portion of a map with cities a and b is shown.The map uses a scale of 1 inch to 30 miles. A new map has a scale of 2 inches=15 miles. How far apart are cities a and b
Answers
Answer:
22.5miles
Step-by-step explanation:
For Map 1;
1 inches = 30miles
For Map 2:
2 inches = 15miles
1 inches = x
2x = 1 *15
x = 15/2
x = 7.5miles
This means that 1 inch represents 7.5miles on Map 2'
The distance between the two cities in miles = 30miles - 7.5miles
The distance between the two cities (in miles) = 22.5miles
Factorise the given expressions :
a) (6p2 – 36p + 30) b) (256 − 64y + 4y2
)
Answers
Answer:
a) Factorizing [tex]6p^2 - 36p + 30[/tex] we get [tex]6(p-5)(p-1)[/tex]
b) Factorizing [tex]4y^2-64y+256[/tex] we get [tex]4(y-8)(y-8)[/tex]
Step-by-step explanation:
Factorise the given expressions :
a) [tex]6p^2 - 36p + 30[/tex]
First we take 6 common:
[tex]6p^2-36p+30\\=6(p^2-6p+5)\\=6(p^2-5p-p+5)\\=6(p(-5)-1(p-5))\\=6(p-5)(p-1)\\[/tex]
So, factorizing [tex]6p^2 - 36p + 30[/tex] we get [tex]6(p-5)(p-1)[/tex]
b) [tex]256 -64y + 4y^2[/tex]
Rearranging terms:
[tex]4y^2-64y+256[/tex]
Taking 4 common
[tex]4(y^2-16y+64)\\4(y^2-8y-8y+64)\\4(y(y-8)-8(y-8))\\4(y-8)(y-8)[/tex]
So, factorizing [tex]4y^2-64y+256[/tex] we get [tex]4(y-8)(y-8)[/tex]
