hello please help me, i’m stuck on this one :(
Answer:
The second option, B.
[tex](x| -3< x \leq 2)[/tex]
Explanation:
Since the point on -3 is hollow, this means that -3 is not included in the equation. Therefore, -3 < x. Since the point on 2 is filled, this means that 2 is a valid number that is included in the equation. Therefore, [tex]x\leq 2[/tex].

Add 8 on both sides
14>2n
Divide
7>n
if john weighs 8lbs less than twice his sister's weight, what is the difference between their weight if john weighs 180 lbs?
Answer:
86 is the difference
Step-by-step explanation:
180 + 8 = 188
188 / 2 = 94
188 - 94 = 86
Answer:
The difference between their two weights is 86 lbs
x•2-8=180 (x= sister weight)
180+8=188
188÷2= 94 (x=94)
189-94= 86

Which of the following equations have no solutions?
Choose all answers that apply:
A
152 - 45 = 750 + 75
B.
15% - 45 = 15x + 75
c
45x – 45 = -15% + 75
D
-450 – 45 = -75x + 75
Answer: B
Step-by-step explanation:
Equation A:
15x - 45 = 75x + 75
=> -120 = 60x
=> x = -2
Equation B:
15x - 45 = 15x + 75
=> 0 = 15
No Solutions
Equation C:
45x - 45 = -15x + 75
=> 60x = 120
=> x = 2
Equation D:
-45x - 45 = -75x + 75
=> 30x = 120
=> x = 4

/4 /4
x = 9
Step-by-step explanation:
subtract 12 from both sides , then divide both sides by 4

Answer:
2,744
Step-by-step explanation:
[tex]C = 400 \sqrt[3]{n} + 200 \\ \\ plug \: C =5800 \\ \\ 5800 = 400 \sqrt[3]{n} + 200 \\ \\ 5800 - 200 = 400 \sqrt[3]{n} \\ \\ 5600 = 400 \sqrt[3]{n} \\ \\ \frac{5600}{400} = \sqrt[3]{n} \\ \\ 14 = \sqrt[3]{n} \\ \\ {(14) }^{3} = {(\sqrt[3]{n})}^{3} \\ (cubing\: both\: sides) \\\\ 2,744 = n \\ \\ n = 2,744[/tex]

I NEED HELP PLZZ :((
5/2 ÷ 3/4
pls help me solve this
Answer:
3 1/3 Because When we divide two fractions, such as 5/2 ÷ 3/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
Step-by-step explanation:
remember to simplify if ever possible!:D
soooo
in order to do this both fractions has to have the same denominator
so you find the CMD (common denominator)
which is 4
so you'd only change 5/2
5/2 * 2/2 to make it 10/4
now both fractions have the same denominator
you do keep change flip
you keep 10/4
change division to multiplication
and flip 3/4 TO 4/3
which would equal
10/4 * 4/3= 40/12
40/12
and you divide it with long division
you get 3 as ur quotient
divisor as 12
and remainder as 4
= 3 4/12
nd u simplify which u divide 4/12 by 4 and get 1/3
so the answer would be 3 1/3
and in order to check you can use an online fraction calculator

Line q goes through points (-3, 3) and (-5, -3). At what point does line q cross the y-axis?
Answer:
(0, 12 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)
m = [tex]\frac{-3-3}{-5+3}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept
Thus the line crosses the y- axis at (0, 12 )
Answer:
It crosses the y-axis at the point where y = 12
- the point (0, 12).
Step-by-step explanation:
First we need to find the equation of the line q:
The slope of the line = (-3-3)/(-5-(-3))
= -6/-2
= 3.
Using the point-slope form of a line:
y - y1 = m(x - x1) Take the point (-3, 3):
y - 3 = 3(x -(-3)
y - 3 = 3x + 9
y = 3x + 12.
Where q crosses the y-axis x = 0 so we have
y = 3(0) + 12
y = 12
The required point is (0, 12).
A certain type of bacteria doubles in population every 6 hours. There were approximately 100 bacteria at the beginning of the day.
How many bacteria will there be at the end of one day?
Answer:
1600 after 24 hours
Step-by-step explanation:
100+100 = 200 after 6 hours
200+200 = 400 after 12 hours
400+400 = 800 after 18 hours
800+800 = 1600 after 24 hours

Answer:
31°
Step-by-step explanation:
The angle 59° will be equal to the angle c in triangle ABC.
Angle B will be 90°
Angle A + Angle B + Angle C = 180° (ASP)
Angle A + 90° + 59 ° = 180 °
Angle A = 180° - 90° - 59°
Angle A = 31°
Angle A = x
31° = x

Factor X^2-13x+22 help pls
Answer:
(x-2)(x-11)
Step-by-step explanation:
Answer:
(x - 2)(x - 11)
Step-by-step explanation:
We have a polynomial and are asked to factor it.
Polynomial : x^2 - 13x + 22
Usually a trick I follow when factoring is that for c (in this case 22). You need to find two numbers that will multiply to it. And for b (in this case -13) you will need to find two numbers that will add to it, the same numbers you multipled for c.
So
x * y = 22
x + y = -13
These two numbers are -11 and -2.
