A student concluded that the inequality −3+2y≤4x is equivalent to the inequality y≥2x+32, as shown below. Describe and correct the student’s error.
Answer:
[tex] -3 +2y \leq 4x[/tex]
[tex] 2y \leq 4x+3[/tex]
[tex] y \leq 2x + \frac{3}{2}[/tex]
And that's different from the claim of the student that:
[tex] y \geq 2x +\frac{3}{2}[/tex]
The error of the student is that he/she changes the sign of the inequality from [tex] \leq[/tex] to [tex]\geq[/tex] and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:
[tex] -3 +2y \leq 4x[/tex]
We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:
[tex] 2y \leq 4x+3[/tex]
Now we can divide both sides of the inequality by 2 and we got:
[tex] y \leq 2x + \frac{3}{2}[/tex]
And that's different from the claim of the student that:
[tex] y \geq 2x +\frac{3}{2}[/tex]
The error of the student is that he/she changes the sign of the inequality from [tex] \leq[/tex] to [tex]\geq[/tex] and that's not possible since we don't multiply both sides of the equation by -1

Step-by-step explanation:
Based on the demand graph and the supply graph shown above, what is the price at the point of equilibrium?
a. 100
b. 70
c. 40
d. There is not enough information given to determine the point of equilibrium.
Answer:
70 Forsure E2020
Step-by-step explanation:
The coordinates of the point of equilibrium are (-60, 110).
What is demand graph?A demand curve is graph that shows the relationship between the price of a good or service and the quantity demanded within a specified time frame.
Mathematically, we can write demand curve equation as -
Q = a - bP
where -
Q = linear demand curve
a = factors influencing demand besides price
b = slope
P = price
Given is to find the price at the point of equilibrium.
Equation for supply curve -
y = mx + c
y = {(25 - 20)/(10 - 0)}x + c
y = x/2 + 20
Equation for demand curve -
y = mx + c
y = {(10 - 20)/(40 - 30)}x + c
y = - x + 50
Point of equilibrium -
The point where demand equals to supply. We can write -
x/2 + 20 = - x + 50
x/2 - x = 30
- x/2 = 30
x = - 60
then -
y = 60 + 50
y = 110
Therefore, the coordinates of the point of equilibrium are (-60, 110).

Answer:
We must calculate the length of the "slope"
Hypotenuse^2 = 11^2 + 4^2
Hypotenuse^2 = 121 + 16
Hypotenuse^2 = 137
Hypotenuse = 11.7
Area of "slope" surface = 11.7 * 6 = 70.2 sq feet
Area of Base = 6 *4 = 24 sq feet
Area of rear side = 6 * 11 = 66 sq feet
Area of both sides = 44 sq feet
Total area = 70.2 + 24 + 66 + 44 = I get 204.2 which is NOT any of the choices.

Step-by-step explanation:
We need to find the value of angle D so that we can solve for X. To do that we need to find the value of angle A and that value will be the same value as D because these angles are the same.
To do that we have to add angles C and B together and that equals 118°. Then we have to realize that all the angles of a triangle add up to 180°. So then we have to subtract 118° from 180° and that equals 62°. So now we have the value of A.
If the value of angle A is 62° then that must be the value of angle D because these two angles are the same. So now that we have the value of angle D we need to solve for X. This equation is asking what times 2 equals the value of X. We know the value of X is 62°. So what times 2 equals 62°?
31×2=62°
Therefore the value of X is 31

how much bigger is the area of a pizza with a diameter of 18 inches than the area of a pizza with a diameter of 10 inches
Answer:
approximately 3.24 times greater
Step-by-step explanation:
The formula for the area of a circle of radius r is A = πr². Because we are given the diameter here (not the radius), we substitute d/2 for r in the above formula, obtaining:
A = π(d/2)²
Case 1: A = π [18 in / 2]² = π(9 in)² = 81π in²
Case 2: A = π[10 in/2]² = π[5 in]² = 25π in²
Dividing 81π in² by 25π in² gives us the desired result:
The area of the larger pizza is 81/25 times the area of the smaller one, or approximately 3.24 times greater.

The volumes of two similar solids are 729m3 and 512 m3. The surface area of the solid is 324m2 What is the surface area of the smaller solid?
Step-by-step explanation:
Step 1: Make an equation
[tex]\frac{volume_1}{surface-area_1} = \frac{volume_2}{surface-area_2}[/tex]
[tex]\frac{729}{324} = \frac{512}{x}[/tex]
Step 2: Cross multiply
[tex]\frac{729}{324} = \frac{512}{x}[/tex]
[tex]729(x) = 324(512)[/tex]
[tex]729x = 165888[/tex]
Step 3: Divide both sides by 729
[tex]729x / 729 = 165888 / 729[/tex]
[tex]x = \frac{165888} {729}[/tex]
[tex]x = 227.555...[/tex]
Answer: [tex]x = \frac{165888} {729}[/tex] or in decimal form - [tex]x = 227.555...[/tex]
Answer:
256 m²
Step-by-step explanation:
(Ratio of sides)³ = Ratio of volumes
729/512 = (Ratio of sides)³
Ratio of sides = 9/8
(Ratio of sides)² = ratio of area
(9/8)² = (324/x)
x = 256
a floor plan is drawn using a scale of 3cm/15ft what length is represented by 1 centimeter ?
A ratio expresses the number of times one number contains another. The length represented by 1 centimeter in real is 5ft.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that a floor plan is drawn using a scale of 3cm/15ft. Therefore, the 3 cm on the floor plan represents 15 ft in real. Thus, we can write the ratio as,
Ratio = Length on floor plan/Length in real = 3cm / 15 ft
Length on floor plan/Length in real = 3cm / 15ft
Now, the length represented by 1 centimeter in real can be written as,
Length on floor plan/Length in real = 3cm / 15ft
1 cm/Length in real = 3cm / 15ft
Length in real = (15ft × 1cm)/3cm
Length in real = 5 ft
Hence, the length represented by 1 centimeter in real is 5ft.

Answer:
StartFraction 8 Over 15 EndFraction
Step-by-step explanation:
We want to represent 0.5333... as a fraction. Let's call x that fraction:
x = 0.5333
Then,
10x = 5.3333
100x = 53.333
100x - 10x = 53.333 - 5.3333
90x = 48
x = 48/90
dividing numerator and denominator by 6, we get:
(48/6) / (90/6) =8/15
Answer:
The simplified fraction is 1/8
The correct option is;
StartFraction 8 Over 15 EndFraction
Step-by-step explanation:
Here, we are given the simplified fraction result as [tex]0.5\bar3[/tex] which is the same as [tex]\frac{1}{2}+\frac{1}{30} =\frac{15+1}{30} =\frac{16}{30} =\frac{8}{15}[/tex]0.53333......
Therefore, to find the simplified fraction, we split the resultant value into the component parts as follows;
[tex]0.5\bar3[/tex] = 0.5 + 0.0[tex]\bar3[/tex]
We observe that the above equation is the same as [tex]\frac{1}{2}+\frac{1}{30}[/tex]
Hence, we simplify [tex]\frac{1}{2}+\frac{1}{30}[/tex] to arrive at
Therefore, the simplified fraction = 1/8.
