Answer:

B

Step-by-step explanation:

this just means that the graph has to have x-intercepts (y = 0) at these x-values.

so, which graph intersects the x-axis at x = -7/3 and x = 1/2 ?

only B does that.

the others have other x-intercept points.

The number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

To solve this problem, you can set up a system of equations to represent the given information. The first equation represents the fact that the company uses 138 pounds of peanuts for every 2/3 pound of raisins:

138 pounds peanuts / 2/3 pound raisins = x pounds peanuts

The second equation represents the fact that the company makes 245 pounds of trail mix using only peanuts and raisins:

x pounds peanuts + y pounds raisins = 245 pounds trail mix

To solve for the number of pounds of peanuts used, you can substitute the first equation into the second equation:

(138 pounds peanuts / 2/3 pound raisins) + y pounds raisins = 245 pounds trail mix

Multiplying both sides of the equation by 2/3 to eliminate the fraction, we get:

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds trail mix)

Combining like terms, we get:

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds)

Simplifying the right side of the equation, we get:

138 pounds peanuts + (2/3)y pounds raisins = 160 pounds

Subtracting 138 pounds from both sides of the equation, we get:

(2/3)y pounds raisins = 160 pounds - 138 pounds

Simplifying the right side of the equation, we get:

(2/3)y pounds raisins = 22 pounds

Dividing both sides of the equation by 2/3, we get:

y pounds raisins = (3/2)(22 pounds)

Simplifying the right side of the equation, we get:

y pounds raisins = 33 pounds

Substituting this value into the first equation, we get:

138 pounds peanuts / 2/3 pound raisins = 33 pounds raisins

Multiplying both sides of the equation by 2/3, we get:

138 pounds peanuts / (2/3)(33 pounds raisins) = 33 pounds raisins

Simplifying the right side of the equation, we get:

138 pounds peanuts / 22 pounds raisins = 33 pounds raisins

Dividing both sides of the equation by 22 pounds raisins, we get:

138 pounds peanuts / 22 pounds raisins / 33 pounds raisins = 33 pounds raisins / 22 pounds raisins

Simplifying the equation, we get:

6 pounds peanuts / 1 pound raisins = 33 pounds raisins / 22 pounds raisins

This equation shows that for every 1 pound of raisins the company uses, they use 6 pounds of peanuts.

Therefore, the number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

138 pounds peanuts / 2/3 pound raisins = x pounds peanuts

The second equation represents the fact that the company makes 245 pounds of trail mix using only peanuts and raisins:

x pounds peanuts + y pounds raisins = 245 pounds trail mix

(138 pounds peanuts / 2/3 pound raisins) + y pounds raisins = 245 pounds trail mix

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds trail mix)

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds)

138 pounds peanuts + (2/3)y pounds raisins = 160 pounds

(2/3)y pounds raisins = 160 pounds - 138 pounds

(2/3)y pounds raisins = 22 pounds

y pounds raisins = (3/2)(22 pounds)

y pounds raisins = 33 pounds

138 pounds peanuts / 2/3 pound raisins = 33 pounds raisins

138 pounds peanuts / (2/3)(33 pounds raisins) = 33 pounds raisins

138 pounds peanuts / 22 pounds raisins = 33 pounds raisins

138 pounds peanuts / 22 pounds raisins / 33 pounds raisins = 33 pounds raisins / 22 pounds raisins

6 pounds peanuts / 1 pound raisins = 33 pounds raisins / 22 pounds raisins

This equation shows that for every 1 pound of raisins the company uses, they use 6 pounds of peanuts.

Therefore, the number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

9/8 is the result when we divide 3/4 by 2/3

Step 1. Take reciprocal of  the second fraction (the one you want to divide by)

Step 2. Multiply the first fraction by the second faction's reciprocal.

The equivalent expression to 2x² + 4 + 3x² + 2x + 7 is 8x² + 2x + 11.

An equivalent equation is an equation that has the same solution set as another equation. It is a mathematical expression that is equal in value to another expression. The two equations can often be solved using the same methods and yield the same result. Equivalent equations are useful in solving complex mathematical problems by breaking them down into simpler equations.

This is obtained by combining the like terms such as 2x² and 3x², which results in 5x², and 4 and 7 resulting in 11. The expression can be written as 5x² + 2x + 11. The final result can be obtained by multiplying 5x² with 2, which results in 8x². Hence, the equivalent expression is 8x² + 2x + 11.

[tex]g(x)=8x+10y=202[/tex]

where x is the cost of a senior citizen ticket and y is the cost of a child ticket.

Solve equation 2 for 5y:

[tex]8x+10y=202\\10y=202-8x\\\frac{10y}{x}=\frac{202-8x}{2}\\5y=101-4x[/tex]

m = 3/13

Answer:

Step-by-step explanation:

To find the slope of the line that passes through the points (-4,5) and (9,8), we can use the formula for slope:

slope = (y2 - y1) / (x2 - x1)

The exact surface area of the cylinder in terms of π is = 10 π

What is the answer for surface area?

As a refresher, the surface area of an object is the sum of the areas of all of its faces, or the exterior surfaces of its three dimensions. It is calculated in square units.

Where can I find the surface area?

A three-dimensional shape's surface area is the total area on its surface. Add the areas of each of the six rectangular sides of a cuboid to determine its surface area. The cuboid's length, width, and height can also be labeled, and the surface area (SA) can be calculated using the formula SA=2lw+2lh+2hw.

Given that :

Radius = 1 1/4 cm

Height = 2 3/4 cm

Surface area is 2π r h + 2π r² = 2π ( 1 1/4 cm*2 3/4 cm) + 2π (1 1/4)²

= 2π (55/16) + 2π (25/16)
