which of the lines graphed has a slope of 1 and a y-intercept of -3?

Answers

Answer: The attached image (Graph 4) is the correct graph.

Step-by-step explanation:

1. Find the graph with the point (0, -3), the y-intercept. This eliminates all but two graphs.

2. Out of the two graphs you have narrowed down the options to, choose the graph with the positive slope (slope of 1). Since graph 3 has a negative slope amd graph 4 has a positive slope and still satisfies the correct intercept, the 4th graph is the correct option.

The distance between two cities on a map is 3.25 centimeters. The map used a scale in which 1 centimeter represents 20 kilometers. What is the actual distance between these two cities in kilometers?

Answers

Answer:

65km

Step-by-step explanation:

Step one:

given

we are told that the distance is 3.25cm on the map

the scale is 1cm to represent 20km

Required

the actual distance

Step two

if 1cm represent 20km

then 3.25cm will represent x km

cross multiply we have

x=2.35*20

x= 65km

Hence, the actual distance between these two cities in kilometers 65km

If 4 is a root of f(x), which of the following is a factor of f(x)?
(x+4)
neither (x+4) nor (x-4)
(x-4)
(x+4) and (x-4)

Answers

Given:

4 is a root of f(x).

To find:

A factor of f(x).

Solution:

We know that, if c is a root of a function f(x), then (x-c) is a factor of f(x).

In the given problem, 4 is a root of f(x).

So, we have c=4.

By using the above property we can say that, (x-4) is a factor of function f(x).

Since, (x-4) is a factor of function f(x), therefore, the correct option is C.

Jackson buys a softball for $15 plus a 6% tax. Avery buys a volleyball for $13 plus a 6% tax. Enter the difference in the amount Jackson and Avery paid, including tax. Round your answer to the nearest cent.

Answers

Answer:

The answer is that the difference in the amount that Jackson and Avery paid including tax is $1.31.

Step-by-step explanation:

First, you have to calculate the amount they paid including the tax by finding the 6% of each price and adding this amount to the price:

-Jackson: $15*6%=0.09

$15+$0.09=$15.09

-Avery: $13*6%=$0.78

$13+$0.78=$13.78

Now, you have to subtract to find the difference:

$15.09-$13.78=$1.31

According to this, the answer is that the difference in the amount that Jackson and Avery paid including tax is $1.31.

The table represents some points on the graph of a linear function. Which equation represents the same relationship?
A. y+286=1/12(x+20)
B. y+20=1/12(x+268)
C. y+268=12(x+20)

lamont is trying to determine how many $5 and $10 bills he needs to make $300 in total he has 35 bills. If x represents the number of $5 bills he has and y represents the number of $10 bills use the graph below to determine how many of each bill he has

Answers

Answer: 10 $5 bills, and 25 $10 bills.

Step-by-step explanation:

Let's define the variables:

F = number of $5 bills.

T = number of $10 bills.

We know that he wants to make $300 in total, then we have:

F*$5 + T*$10 = $300

And we also know that in total there are 35 bills, then:

F + T = 35.

So we have the system of equations:

F*$5 + T*$10 = $300

F + T = 35

To solve this, the first step is isolate one of the variables in one of the equations, i will isolate F in the second equation to get:

F = 35 - T

Now we can replace that in the other equation, and get:

(35 - T)*$5 + T*$10 = $300

Now we can solve this equation for T.

$175 - T*$5 + T*$10 = $300

T*$5 = $300 - $175 = $125

T = $125/$5 = 25

and:

F = 35 - T = 35 - 25 = 10

Then he has:

10 $5 bills, and 25 $10 bills.

Describe your approach to solving a given triangle. Include specific details about what you look for and how you start the problem. What are the important pieces of information that affect how you solve the triangle?
(edginuity)

Answers

Answer:

In order to solve a right triangle, you must first figure out which angle is the right angle. Knowing the right angle will also tell you which side is the hypotenuse, since the hypotenuse will always stand opposite the right angle. In this text, for the sake of consistency, in all triangles we will designate angle C as the right angle, and side c and the hypotenuse. To finish solving a right triangle, you then must either know the lengths of two sides, or the length of one side and the measure of one acute angle. Given either of these two situations, a triangle can be solved. Any further information about a triangle may be helpful, but it is not necessary.There are four basic techniques to use in solving triangles.Using the Pythagorean Theorem, once two sides are known, the third side can be calculated.Using the fact that the acute angles of a right triangle are complementary, once one acute angle is known, the other can be calculated.Using the definitions of the trigonometric functions, any two parts of a triangle can be related in an equation to equal a third part.Using the definitions of the inverse trigonometric functions, any two sides of a triangle can be related in an equation to equal the inverse function of an unknown acute angle

Barb is looking at internet service plans. A local company offers a one month service plan for $39.95 for a two month service plan for $68.97 dollars how much would Barb save in 2 months if she only got two month plan instead of two one month plans enter?

Answers

Answer:

Barb would save $10.93 in 2 months if she only got two month plan instead of two one month plans.

Step-by-step explanation:

First, you need to determine the amount that Barb will pay with the one month service plan in 2 months:

$39.95*2= $79.9

Now, you need to calculate the difference between both plans:

$79.9-$68.97=$10.93

According to this, the answer is that Barb would save $10.93 in 2 months if she only got two month plan instead of two one month plans.
