Tell whether the following equation has one, zero, or infinitely many solutions. 2(4x + 10) = 8x + 20. Group of answer choices:

A) Infinitely many solutions

B) One solution

C) Zero solutions

Answers

Answer 1

Answer:

The equation will have infinitely many solutions.

Option A is correct

Step-by-step explanation:

We need to tell if the equation [tex]2(4x + 10) = 8x + 20[/tex] has one, zero, or infinitely many solutions.

First we solve the equation to find the value of x

[tex]2(4x + 10) = 8x + 20[/tex]

First multiply 2 with terms inside the bracket

[tex]8x+20=8x+20[/tex]

Now Subtract 20 from both sides

[tex]8x+20-20=8x+20-20[/tex]

[tex]8x=8x\\0=0[/tex]

So, the equation will be true for all values of x

As after solving the equation we get 0=0 so, the equation will have infinitely many solutions.

Option A is correct

Answer:

x=4

Step-by-step explanation:

It's a parallel line so the equation is

100+19x+4=180

19x=180-100-4

19x=76

x=76/19

x=4

Answer: x = 4

Step-by-step explanation: The 2 angles are same-side interior angles, which are supplementary, and supplementary angles add up to 180, so we know that 19x + 4 = 80.

19x = 76

Mr Mason asks 240 year 11 students what they want to do next year. 15% of the students want to go to college. ¾ of the students want to stay at school. The rest of the students do not know. Work out the number of students who do not know.

Answers

Answer:

Number of students who do not know = 24

Step-by-step explanation:

Year II students = 240

15% of the students want to go to college.

Number of year II students who wants to go to college = 15% of 240

= 15/100 × 240

= 0.15 × 240

= 36

¾ of the students want to stay at school.

Number of students who wants to stay at the school = 3/4 × 240

= (3 × 240) / 4

= 720 / 4

= 180

Number of students who do not know = Total year II students - Number of year II students who wants to go to college - Number of students who wants to stay at the school

= 240 - 36 - 180

= 24

Number of students who do not know = 24

Two companies rent moving trucks. Pack and Go charges a $39.95 flat fee, and $0.45 for every mile driven. U-Drive charges a $59.95 flat fee, and $0.35 for every mile driven. At how many miles is the cost of the truck rentals the same?

Answers

Answer:

The indifference point is 200 miles

Step-by-step explanation:

First, we need to establish the total cost formula for each company:

Pack and Go:

Total cost= 39.95 + 0.45x

x= miles driven

U-Drive:

Total cost= 59.95 + 0.35x

x= miles driven

Now, we equal both formulas and isolate x:

39.95 + 0.45x = 59.95 + 0.35x

0.1x = 20

x= 200 miles

The indifference point is 200 miles

Answer:

A is answer 1/ 39.95 + .45x = 59.95 + .35x

B is answer 3/ miles driven

C is 3 /200

25.) Slope of AB = 5

Slope of CD = -1/5

Perpendicular

26.) Slope of EF = -3/5

Slope of GH = -3/5

Parallel

Step-by-step explanation:

Use this formula to find slope. [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Parallel lines have the same slope

Perpendicular lines have the opposite reciprocal and sign

25.)

Plug in AB slope is 5

2 - 7/ 3 - 4 = -5/-1 = 5

Plug in for CD slope is -1/5

3 - 4/ 2 - -3 = -1/5 = -1/5

The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.

26.)

Plug in EF slope is -3/5

1 - 4/ 3 - -2 = -3/5 = -3/5

Plug in GH slope is -3/5

-5 - -2/ 4 - -1 =  -3/5 = -3/5

The lines EF and GH are parallel lines because they have the same slopes.
