I'm stuck on this problem! A linear function that represents the number of video games purchased at an electronics store is compared to a different linear function that represents the amount of money the store made that day. Describe the key features of the functions that are needed to determine if these lines intersect.

Answers

Answer 1

Answer:

In order two straight lines in a coordinate plane intersect, they MUST have different slopes.

This condition is  NECESSARY  and  SUFFICIENT.

Step-by-step explanation:

Answer 2

The key feature of the functions that are needed to determine if the lines intersect are;

The slope; rate of changeThe y-intercept

Slope and y-intercept

From straight line geometry, we can conclude that two parallel lines whose slope are equal can never intersect.

On this note, for the functions described in the question, the functions only intersect when the slopes are different.

Additionally, the functions may intersect in the event of having equal y-intercepts.

Mrs. Hales then tells Kyle to write an equation showing that the volume, V, of each of his prisms is equal to l × w × h

Answers

Kindly check the complete version of the question on the picture attached below :

Answer:

B.) 4 * 3 * 3

Step-by-step explanation:

Unit volume of cube = 48 unit³

Using the volume relation :

Volume = Length * width * height

V = l * w * h

To obtain the odd representation, we calculate the volume of the dimensions given in the option and select the option which does not yield a volume of 48 unit³

A.) 8 * 2 * 3 = 48 unit³

B.) 4 * 3 * 3 = 36 unit³

C.) 6 * 2 * 4 = 48 unit³

D.) 3 * 2 * 8 = 48 unit³

Hence, prism with dimension 4 * 3 * 3 cannot be one of Kyle's prism

In circle O, m∠R = 30.8°. Find m∠NOQ.

Answers

Given:

In circle O, m∠R = 30.8°.

To find:

The m∠NOQ

Solution:

Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.

Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.

Using central angle theorem, we get

[tex]m\angle NOQ=2\times m\angle NRQ[/tex]

[tex]m\angle NOQ=2\times m\angle R[/tex]

[tex]m\angle NOQ=2\times 30.8^\circ[/tex]

[tex]m\angle NOQ=61.6^\circ[/tex]

Therefore, [tex]m\angle NOQ=61.6^\circ[/tex].

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Starting from a full tank, can Diego's family drive the car for 14 days without the warning light coming on? Explain your reasoning.

Answers

Answer:

20 days

Step-by-step explanation:

Subtract 1.5 gallons from 14 gallons to obtain the number of days the car will run without the warning light going on:  12.5 gallons.

Dividing this result by 0.6 gallons/day, we get

 12.5 gal

Answer:

66 cm (Option B)

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr, so plug the values into the formula.  The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5.  Use 3.14 for π.  

C = 2πr

C = 2(3.14)(10.5)

C = 6.28 × 10.5

C = 65.94

Rounded to the nearest unit, you get a answer of 66 cm.

Answers

Answer:

she had a perfect score in 1/8 of all tests

she had a perfect score in 4 tests

Step-by-step explanation:

Tamara earned an A in 5/8 of all the tests she took.

In 1/5 of the those tests she got an A, she had a perfect score.

1/5 of 5/8 is 1/5 * 5/8 which equals 5/40 which can be reduced to 1/8.

That means that in 1/8 of all tests she took she got a perfect score.

She took a total of 32 spelling tests.

1/8 of 32 = 1/8 * 32 = 32/8 = 4

Answer:

she had a perfect score in 1/8 of all tests

Define angle bisector.

An angle bisector is defined as a ray, segment, or line that bisects a given angle into two equal angles. The word bisection or half means dividing one object into two equal or identical parts. In geometry, we usually divide triangles and angles by lines or lines that are considered bisectors.

A geometric bisector is a ray, line, or segment that divides a given angle into two equal parts. For example, the bisector of a 60 degree angle divides it into two 30 degree angles. In other words, split the angle into two smaller congruent angles.

For the given case,

Ray BD bisects ∠ABC into two equal angles ∠ABD and ∠DBC; which can be written as ∠ABD = ¹/₂ ∠ABC.

The complete question is as follows:

x + 2y = 1 and 2x + 5y = 3.

Can someone help me , with process to please ?

I will appreciate thank you so much!

Answers

Answer:

x = -1

y = 1

Step-by-step explanation:

x + 2y = 1     (Multiply this by -2)

2x + 5y = 3

-2x - 4y = -2

2x + 5y = 3

y = 1

x + 2y = 1

x + 2(1) = 1

x + 2 = 1

x = 1 - 2

x = -1

Answer:

x = -1

y = 1

Step By Step Explanation:

x + 2y = 1

2x + 5y = 3

let x become the subject. use one of the equation.

x = 1 - 2y

substitute into another equation

2(1 - 2y) + 5y = 3

expend the bracket

2 - 4y + 5y = 3

collect like terms

- 4y + 5y = 3 - 2

y = 1

substitute into one of the equation to find x

x + 2y = 1

x + 2 (1) = 1

x + 2 = 1

collect like terms

x = 1 - 2

x = - 1

I think you know Bc the other person already said it so give em brainlest

Answer:

 =  1 0

Step-by-step explanation:

Solve

1. Combine like terms

2  +  2 0  + 2  =  6 0

4  +  2 0  =  6 0

2. Subtract  20  from both sides of the equation

4  +  2 0  =  6 0

4  +  2 0  −  2 0  =  6 0  −  2 0

3. Simplify

Subtract the numbers

4  +  2 0  −  2 0 =  6 0  −  2 0

4  =  6 0  −  2 0

Subtract the numbers

4 =  6 0  −  2 0

4  =  4 0

4. Divide both sides of the equation by the same term

4x = 40

4x/4 = 40/4

5. Simplify

Cancel terms that are in both the numerator and denominator

4x/4 = 40/4

x = 40/4

Divide the numbers

x = 40/4

x = 10
