Carl and Laura are reading different copies of the same book. Carl has already read 10 pages of his copy of the book when Laura begins reading her copy of the book. A system of equations can be used to compare the number of pages (y) each person has read x minutes after Laura begins reading her copy of the book. The solution to the system of equations is (40, 50). What does the solution (40, 50) represent in this situation?
a.)Carl and Laura have both read 50 pages after Laura has been reading for 40 minutes.
b.)Carl has read 50 pages and Laura has read 40 pages.
c.)Carl has read 40 pages and Laura has read 50 pages.
d.)Carl and Laura have both read 40 pages after Laura has been reading for 50 minutes.
Final answer:
The solution (40, 50) to the system of equations indicates that after 40 minutes, Laura has read 40 pages and Carl, with a head start, has read a total of 50 pages, option D.
Explanation:
The solution to the system of equations (40, 50) represents the amount of time Laura has spent reading and the number of pages both Carl and Laura have read. In this context, 'x' represents the number of minutes Laura has been reading her copy of the book, and 'y' represents the number of pages each person has read. Therefore, the solution (40, 50) means that after Laura has been reading for 40 minutes, Laura has read 40 pages, and Carl, who had a 10-page head start, has read a total of 50 pages.

What size picture will result when a 5 in. • 7 in. Picture is reduced using an 80% setting?
A 5" * 7" image reduced by 20% in scale to 80% of the original size will be 4" * 5.6". Roughly the size of a large flash card.
When a 5 inch by 7 inch picture is reduced using an 80% setting, the new dimensions will be 4 inches by 5.6 inches.
To calculate the new size of a 5 inch by 7 inch picture when reduced by 80%, we simply multiply both dimensions by the reduction percentage. Hence, the width and the height of the picture will be reduced to 80% of their original size.
Original width: 5 inches
Original height: 7 inches
Reduction setting: 80% (or 0.8)
New width: 5 inches × 0.8 = 4 inches
New height: 7 inches × 0.8 = 5.6 inches
Therefore, the new dimensions of the picture will be 4 inches by 5.6 inches after an 80% reduction.
A company produces and sells widgets and gizmos. In January the company sold 350 items for a total of $9,000. If each widget sold for $35, and each gizmo sold for $22, how many of each item did the company sell? Let x1 = the number of widgets sold and x2 = the number of gizmos sold.
Write an equation relating the number of each item sold to the total number sold: x1 + x2 =
Answer:
The company sold 100 widgets and 250 gizmos.
Step-by-step explanation:
Let [tex]x_1[/tex] be the number of widgets sold and [tex]x_2[/tex] be the number of gizmos sold.
We are told that the company sold 350 items. We can represent this information in an equation as:
[tex]x_1+x_2=350...(1)[/tex]
We have been given that a each widget sold for $35 and each gizmo sold for $22. The company sold 350 items for a total of $9,000.
We can represent this information in an equation as:
[tex]35x_1+22x_2=9,000...(2)[/tex]
From equation (1), we will get:
[tex]x_2=350-x_1[/tex]
Substitute this value in equation (2):
[tex]35x_1+22(350-x_1)=9,000[/tex]
[tex]35x_1+7,700-22x_1=9,000[/tex]
[tex]13x_1+7,700=9,000[/tex]
[tex]13x_1+7,700-7,700=9,000-7,700[/tex]
[tex]13x_1=1,300[/tex]
[tex]\frac{13x_1}{13}=\frac{1,300}{13}[/tex]
[tex]x_1=100[/tex]
Therefore, the company sold 100 widgets.
Substitute [tex]x_1=100[/tex] in equation (1):
[tex]100+x_2=350[/tex]
[tex]100-100+x_2=350-100[/tex]
[tex]x_2=250[/tex]
Therefore, the company sold 250 gizmos.
Answer:
x1 + x2 = 350
Step-by-step explanation:
The total number of items sold is the sum of the number of widgets sold and the number of gizmos sold:
(widgets sold) + (gizmos sold) = total items sold
We are supposed to represent widgets sold using x1, and gizmos sold using x2. The total number of items sold is given in the problem statement as 350. Substituting these values into the above equation, we get the equation you're looking for:
x1 + x2 = 350

Solve the inequality-x/2 ≤ 1
Answer:
Step-by-step explanation:
Solve the inequality -x/2 ≤ 1. Let's eliminate the fraction first, by multiplying both sides by 2:
-x ≤ 2
We want to solve for +x, not for -x.
Therefore, divide both sides of this latest inequality by -1, remembering to reverse the direction of the inequality sign:
-x ≤ 2 → x ≥ -2
According to the rational root theorem which is a factor of the polynomial f(x)=3x^3-5x^2-12x+20
Answer:
[tex]f(x)=3(x+2)(x-2)(x-\frac{5}{3})[/tex]
Step-by-step explanation:
The rational roots theorem tells you that given a polynomial function with integer or whole number coefficients, a list of possible solutions can be found by listing the factors of the constant, or last term, over the factors of the coefficient of the leading term.
In your case, for the polynomial [tex]f(x)=3x^3-5x^2-12x+20:[/tex]
the last term is 20;the leading coeeficient is 3.So, possible rational roots can be among:
[tex]\pm1,\pm2,\pm4,\pm5,\pm10,\pm20,\pm\dfrac{1}{3},\pm\dfrac{2}{3},\pm\dfrac{4}{3},\pm\dfrac{5}{3},\pm\dfrac{10}{3},\pm\dfrac{20}{3}.[/tex]
Note that
[tex]f(-2)=3\cdot (-2)^3-5\cdot (-2)^2-12\cdot (-2)+20=-24-20+24+20=0.[/tex]
This means that [tex]x=-2[/tex] is a root of the polynomial and [tex]x-(-2)=x+2[/tex] is the factor. Also
[tex]f(2)=3\cdot 2^3-5\cdot 2^2-12\cdot 2+20=24-20-24+20=0.[/tex]
This means that [tex]x=2[/tex] is a root of the polynomial and [tex]x-2[/tex] is the factor. Also
[tex]f(\frac{5}{3})=3\cdot (\frac{5}{3})^3-5\cdot (\frac{5}{3})^2-12\cdot \frac{5}{3}+20=\frac{125}{9}-\frac{125}{9}-20+20=0.[/tex]
This means that [tex]x=\frac{5}{3}[/tex] is a root of the polynomial and [tex]x-\frac{5}{3}[/tex] is the factor.
Then
[tex]f(x)=3(x+2)(x-2)(x-\frac{5}{3}).[/tex]

A recipe calls for 2/3 cup of flour for every 4 teaspoons of vanilla. How much vanilla should be used for every 1 cups of flour?
A. 1/6
B. 2 2/3
C. 4 2/3
D. 6
Please help and explain everything! Thanks!
Answer: For 1 cup of flour, there should be 6 teaspoons of vanilla.
Step-by-step explanation:
What I did is that I found what 1 ÷ 2/3 equals. To find that, I used the reciprocal so the new equation would be 1 × 3/2 which equals 3/2. So since 2/3 × 3/2 equals 1, we have to do the same to 4 teaspoons. 4 × 3/2 equals 6. Therefore, there should be 6 teaspoons of vanilla for every one cup of flour.
Hope this helps! Don't hesitate to ask for clarification.
find the LCM of m^2 - 4m - 5 and m^2 + 8m + 7
Answer:
LCM=(m+1)(m-5)(m+7)
Step-by-step explanation:
Given expressions are [tex]m^2-4m-5[/tex] and [tex]m^2+8m+7[/tex].
To find the LCM, first we need to find factors of both expressions.
[tex]m^2-4m-5[/tex]
[tex]=m^2+1m-5m-5[/tex]
[tex]=m(m+1)-5(m+1)[/tex]
[tex]=(m+1)(m-5)[/tex]
Similarly factor other expression
[tex]m^2+8m+7[/tex]
[tex]=(m+1)(m+7)[/tex]
Common factor in both is (m+1)
bring down remaining non-common factors.
So LCM=(m+1)(m-5)(m+7)

Step-by-step explanation:
30 - 12 = 18
18 / 30 × 100 = 60
Write the following equation in slope intercept:
2x + 3y = 12
Y = mx + b
2x + 3y = 12
3y = -2x + 12
y = -2/3 + 4
Answer:
y = -2/3x +4
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
2x+3y = 12
We need to solve for y
Subtract 2x from each side
2x-2x+3y = -2x+12
3y = -2x+12
Divide by 3
3y/3 = -2/3 x +12/3
y = -2/3x +4
Use the quadratic formula s to solve 2y^2-6y-8=0
{-4,-1}
{4,-1}
{-4,1}
{4,1}
Answer:
{4, - 1}
Step-by-step explanation:
Given
2y² - 6y - 8 = 0 ← in standard form
with a = 2, b = - 6, c = - 8
Using the quadratic formula to solve for y
y = ( - (- 6) ± [tex]\sqrt{(-6)^2-(4(2)(-8)}[/tex] ) / (2 × 2)
= ( 6 ± [tex]\sqrt{36+64}[/tex] ) / 4
= ( 6 ± [tex]\sqrt{100}[/tex] ) / 4
= ( 6 ± 10 ) / 4
x = [tex]\frac{6+10}{4}[/tex] = [tex]\frac{16}{4}[/tex] = 4
OR
x = [tex]\frac{6-10}{4}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1
Solution is { 4, - 1 }

Answer:
3x(x - 4)(x + 2)
Step-by-step explanation:
Given
3x³ - 6x² - 24x ← factor out common factor of 3x from each term
= 3x(x² - 2x - 8) ← factor the quadratic
Consider the factors of the constant term (- 8) which sum to give the coefficient of the x- term.
The factors are - 4 and + 2, since
- 4 × 2 = - 8 and - 4 + 2 = - 2, thus
x² - 2x - 8 = (x - 4)(x + 2) and
3x³ - 6x² - 24x = 3x(x - 4)(x + 2)

The total area of two rectangles can be represented by the expression (x)(3x+1) + (2x)(x+3). Which expression represents the total area of the two rectangles?
Answer:
The total area of the two rectangles is [tex](5x^{2} +7x)\ units^{2}[/tex]
Step-by-step explanation:
Area of rectangle 1
[tex](x)(3x+1)=(3x^{2} +x)\ units^{2}[/tex]
Area of rectangle 2
[tex](2x)(x+3)=(2x^{2} +6x)\ units^{2}[/tex]
therefore
The total area of the two rectangles is equal to
[tex](3x^{2} +x)\ units^{2}+(2x^{2} +6x)\ units^{2}=(5x^{2} +7x)\ units^{2}[/tex]
The correct choice is [tex]5x^{2} +7x[/tex]. By expanding and combining the terms, the total area of the two rectangles is represented by the expression found.
Let's first expand each term in the expression (x)(3x+1) + (2x)(x+3) to determine the total area of the two rectangles:
(x)(3x+1) = [tex]3x^{2} +x[/tex](2x)(x+3) = [tex]2x^{2} +6x[/tex]Now, add the two results together:
[tex]3x^{2}[/tex] + x + [tex]2x^{2}[/tex] + 6x = [tex]5x^{2} +7x[/tex]Therefore, the expression that represents the total area of the two rectangles is [tex]5x^{2} +7x\\[/tex] .

You start driving north for 32 miles, turn right, and drive east for another 24 miles.
How many miles must you travel to return directly back to your starting point?
Answer:
40 miles
Step-by-step explanation:
You can recognize the right triangle as a 3-4-5 right triangle with a scale factor of 8. So the length of the hypotenuse is 8·5 = 40 miles.
