Answer:
x ≤ $12
Step-by-step explanation:
Since Maggie has $16 to spend for the week, she can spend less than $16 or exactly $16. Thus, the inequality used would be ≤, which can be read as 'less than or equal to'.
Let the amount of money she has left to spend for the week be x.
Total spending for the week ≤ $16
$4 +spending for the rest of the week ≤ $16
$4 +x ≤ $16
Subtract both sides by $4:
x ≤ $16 -$4
x ≤ $12

Answer:
b = 0b = 4Step-by-step explanation:
[tex] \frac{5}{ {3b}^{3} - {2b}^{2} - 5 } = \frac{2}{ {b}^{3} - 2 } \\ 5( {b}^{3} - 2) = 2( {3b}^{3} - {2b}^{2} - 5) \\ {5b}^{3} - 10 = {6b}^{3} - {4b}^{2} - 10 \\ 10 - 10 = {6b}^{3} - {5b}^{3} - {4b}^{2} \\ 0 = {b}^{3} - {4b}^{2} \\ 0 = {b}^{2} (b - 4) \\ [/tex]
b = 0 or b - 4 = 0

Solve the following equation
Answer:
n = -13
Step-by-step explanation:
38 = -2n + 12
Subtracting 12 from both sides:
==> 38 - 12 = -2n + 12 - 12
==> 26 = -2n
multiplying both sides by (-1):
==> -26 = 2n
dividing both sides by 2:
==> -13 = n
Answer:
Step-by-step explanation:
38 = -2n + 12
26 = -2n
n = 26 : (-2)
n = -13
-----------------
check
38 = -2 * (-13) + 12
38 = 26 + 12
38 = 38

What is a Simplified Expression?A simplified expression is an expression that is evaluated to its simplest form, that is, it cannot be simplified further.
Given:
(6x - 2) - (-x + 5)
Open the bracket by multiplying each of the terms in (-x + 5) by the negative sign (-):
6x - 2 + x - 5
Combine like terms

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8400ft, the liquid boils at 202.92°F. At an altitude of 4400ft, the liquid
boils at 207.72°F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the
liquid at 2200 ft?
Answer:(a) getting the equation:
We'll assume that the altitude is represented by the x-axis and that the boiling point is represented by the y-axis.
Therefore, we have two given points:
(8400 , 200.4) and (4200 , 206.7)
Since the relation is linear, therefore, the graph forms of straight line with the general equation:
y = mx + c where m is the slope and c is the y-intercept.
First, we will calculate the slope:
m = (y2-y1) / (x2-x1) = (206.7 - 200.4) / (4200 - 8400) = -0.0015
Therefore, the equation of the line now is:
y = -0.0015x + c
Then, we will need to calculate the y-intercept. In order to do so, we will use any give point and substitute in the previously obtained equation as follows:
y = -0.0015x + c
206.7 = -0.0015(4200) + c
c = 213
Based on the above calculations, the equation of the line is:
y = -0.0015x + 213
(b) getting the boiling point at altitude = 2100 ft:
Now, in order to calculate the boiling point at altitude 2100, we will substitute in the equation of the line as follows:
y = -0.0015(2100) + 213 = 209.85 degrees Fahrenheit
Step-by-step explanation:
If y varies directly as x and z, y=108 when x=8 and z=3 find y when x =2 and z=1

Answer:
a) x = -2
b) 8 integer values
Step-by-step explanation:
Matthew's solution is correct as far as it goes. However, he failed to take into account the possibility of negative square roots.
His solution might rightly look like ...
3 < 3x² ≤ 75
1 < x² ≤ 25 . . . . . divide by 3
1 < ±x ≤ 5 . . . . . . take the square root
Separating the results:
1 < x ≤ 5
-1 > x ≥ -5 . . . . . . multiply by -1
a)The value x=-2 shows Matthew's solution is incorrect:
3 < 3(-2)² ≤ 25 ⇒ 3 < 12 ≤ 25 . . . true
__
b)x can have the integer values {-5, -4, -3, -2, 2, 3, 4, 5}, a total of 8 values.

In the attached, the white space (and dashed line) are the solution set. The shaded areas (and solid line) are excluded from the solution set.

It can be helpful to remember that ...

At what point does the graph of y=9x(x is exponent) cross the y-axis?
A. (0,9)
B. (9,0)
C. (0,1)
D. (1,0)
Answer:
-The graph crosses the y-axis at the point (0,0)
None of the given options is correct
A graph crosses the y-axis at the point (0,y).This means that the graph will cross the y-axis when x-=0
To find the point where the graph crosses the y-axis,substitute x=0 into the given equation y-9x
substitute x=0 into the equation y-9x to find the corresponding value of y
That is,
y=9(0)
y=0
therefore the graph crosses the y-axis at the point (0,0)

A camel can drink 15 gallons of water in 10 minutes. At this rate, how much water can the camel drink in 6 minutes?
Answer:
9 gallons of waterStep-by-step explanation:
Given,
A camel drinks water in 10 minutes = 15 gallons
So,
Water drank by the camel in 1 minute = [tex]\frac{15}{10} gallon[/tex]
So, Water drank by the camel in 6 minutes
= ( [tex]\frac{15}{10}[/tex] × 6) gallons
[On Simplifying]= 1.5 × 6 gallons
[On multiplying]= 9 gallons
Hence,
Amount of water drank by the camel in 6 minutes is 9 gallons of water. (Ans)

Here mark the angles
m<FHG=75m<FGH=55m<GHI=59°m<GIH=63°By using angle sum property
m<IGH=180-122=58So
m<FGH < m<IGH <m<GHI <m<GIH <m <FHGSo
FH<IH<GI<GH<FGAnswer:
IH < GI < GH < FH < FG
Step-by-step explanation:
Find missing angles
Sum of interior angles of a triangle = 180°
⇒ ∠GFH = 180 - 55 - 75 = 50°
⇒ ∠IGH = 180 - 59 - 63 = 58°
Side lengths in relation to interior angles
The longest side of a triangle is opposite the largest interior angle, and the shortest side is opposite the smallest angle.
Therefore, angles/sides in order of least to greatest:
ΔIGH
∠IGH = 58 → its opposite side is IH
∠GHI = 59 → its opposite side is GI
∠G|H = 63 → its opposite side is GH
Therefore, IH < GI < GH
ΔFGH
∠GFH = 50 → its opposite side is GH
∠FGH = 55 → its opposite side is FH
∠FHG = 75 → its opposite side is FG
Therefore, GH < FH < FG
Combining: IH < GI < GH < FH < FG
