Answer:

1. slope is 7 and y-intercept is 9

2.slope is -5 and y-intercept is -2

3. slope is 3 and y-intercept is 1

Step-by-step explanation:

The standard equation of a line in slope form is;

y=mx + b where m is the slope and b is the y intercept.

In question 1.

y=7x + 9

slope is 7 and y-intercept is 9

In question 2

y= -5x - 2

slope is -5 and y-intercept is -2

In question 3

y= 3x + 1

slope is 3 and y-intercept is 1

Answer:

x = 7/4

Step-by-step explanation:

5-4x+2=0

= -4x +5 +2 =0

= -4x + 7 = 0

= -4x +7-7 = 0-7

= -4x = -7

divide both sides by -4

and u got

x = 7/4

Answer:

3/4

Step-by-step explanation:

Step 1:

5 - 4x + 2 = 0       Equation

Step 2:

3 - 4x = 0      Combine Like Terms

Step 3:

3 = 4x      Add 4x on both sides

Step 4:

x = 3 ÷ 4      Divide

Answer:

x = 3/4

Answer:

1. Lin 6 7/8 miles, Noah 6 1/2 miles

2. Lin will take 8 8/11 minutes while Noah will take 9 3/13 minutes

3. Lin ran faster because it took him less amount of time to cover same distance of 1 hour

Step-by-step explanation:

Here, we are told that Lina ran 2 3/4 miles in 2/5 of an hour while Noah ran 8 2/3 miles in 4/3 of an hour.

1. We want to know how far Noah will run in an hour

1 hour is 60 minutes;

So 4/3 of an hour is 4/3 * 60 = 80 minutes

thus;

if he ran 8 2/3 miles in 80 minutes

then he ran x miles in 1 hour(60 minutes)

8 2/3 is same as 26/3 miles

Thus;

26/3 * 60 = 80 * x

x = 26/3 * 60/80 = (26 * 20)/80 = 26/4 = 13/2 = 6 1/2 miles

Lin ran 2 3/4 miles in 2/5 hour (2/5 * 60 = 24 minutes)

2 3/4 miles took 24 minutes

x mile will take 60 minutes

60 * 2 3/4 = 24 * x

60 * 11/4 = 24x

165 = 24x

x = 165/24

x = 6 21/24 = 6 7/8 miles

Lin will run 6 7/8 miles in an hour

2. we want to know how long it will take both of them to run 1 mile

Lin ran 2 3/4 miles in 2/5 of an hour

meaning, he ran 2 3/4 in 2/5 * 60 = 24 minutes

2 3/4 miles was ran in 24 minutes

1 mile will take x minutes

1 * 24 = 2 3/4 * x

24 = 11/4 * x

x = 4 * 24/11 = 96/11 = 8 8/11 minutes

For Noah

6 1/2 miles was ran in 1 hour

1 mile will be ran in x hours

13/2 * x = 60 minutes * 1

x = (2 * 60)/13

x = 120/13

x = 9 3/13 minutes

c. Lin ran faster because he took the lesser amount of time to travel 1 mile

Answer:

1. Lin 6 7/8 miles, Noah 6 1/2 miles

2. Lin will take 8 8/11 minutes while Noah will take 9 3/13 minutes

3. Lin ran faster because it took him less amount of time to cover same distance of 1 hour

Step-by-step explanation:

Step-by-step explanation:

Here, we are told that Lina ran 2 3/4 miles in 2/5 of an hour while Noah ran 8 2/3 miles in 4/3 of an hour.

1. We want to know how far Noah will run in an hour

1 hour is 60 minutes;

So 4/3 of an hour is 4/3 * 60 = 80 minutes

thus;

if he ran 8 2/3 miles in 80 minutes

then he ran x miles in 1 hour(60 minutes)

8 2/3 is same as 26/3 miles

Thus;

26/3 * 60 = 80 * x

x = 26/3 * 60/80 = (26 * 20)/80 = 26/4 = 13/2 = 6 1/2 miles

Lin ran 2 3/4 miles in 2/5 hour (2/5 * 60 = 24 minutes)

2 3/4 miles took 24 minutes

x mile will take 60 minutes

60 * 2 3/4 = 24 * x

60 * 11/4 = 24x

165 = 24x

x = 165/24

x = 6 21/24 = 6 7/8 miles

Lin will run 6 7/8 miles in an hour

2. we want to know how long it will take both of them to run 1 mile

Lin ran 2 3/4 miles in 2/5 of an hour

meaning, he ran 2 3/4 in 2/5 * 60 = 24 minutes

2 3/4 miles was ran in 24 minutes

1 mile will take x minutes

1 * 24 = 2 3/4 * x

24 = 11/4 * x

x = 4 * 24/11 = 96/11 = 8 8/11 minutes

For Noah

6 1/2 miles was ran in 1 hour

1 mile will be ran in x hours

13/2 * x = 60 minutes * 1

x = (2 * 60)/13

x = 120/13

x = 9 3/13 minutes

c. Lin ran faster because he took the lesser amount of time to travel 1 mile

Answer:

$42

Step-by-step explanation:

5 divided by $30 so each ticket would be $6 then just multiply $6 and 7

Answer:

It would cost $42 because 30 divided by 5 equals 6, so that's saying for each  1 ticket it costs $6. So with the new equation, 7 x $6, we get $42. Which will end up being the cost for 7 tickets.

Given:

Student's verbal score, y, based on the student's math score, x is

[tex]y=0.4433x+307.68[/tex]

To find:

The meaning of slope of this equation in terms of the context of the problem.

Solution:

Slope intercept form of a linear equation is

[tex]y=mx+b[/tex]             ...(i)

where, m is slope and b is y-intercept.

The given equation is

[tex]y=0.4433x+307.68[/tex]          ...(ii)

On comparing (i) and (ii), we get

[tex]m=0.4433[/tex]

Therefore, the slope of the linear equation is 0.4433. It means, student's verbal score, y increased by 0.4433 if the student's math score, x increased by 1.

Answer:

B. 1/4T

Step-by-step explanation:

A student club started a fundraising effort to support animal rescue organizations. The club sent an information flyer home to the n students in the school. It says, "We welcome donations of any amount, including any change you could spare!" Their goal is to raise T dollars, and to donate to a cat shelter and a dog shelter.

What expression, equation, or inequality that describes The dollar amount the club would have if they reached one-fourth of their goal

A. 3/4n × 1/2

B. 1/4T

C. T - 1/4n

D. 1/4n

Their goal is to raise T dollars

The T dollars will be donated to a cat shelter and a dog shelter.

One - fourth = 1/4

Their goal =T

one-fourth of their goal

= 1/4 * T

= 1/4T

The correct answer is B. 1/4T

Answer:

The meaning of rigid corresponds with rigid motion

Step-by-step explanation:

Rigid motion in geometry occurs when a point or object is moved, but the size and shape remain the same. It is also referred to as RIGID TRANSFORMATION.

Therefore, the meaning of the word rigid, which means "not bendable", and another is "unable to be changed" corresponds to the definition of rigid motion.

Rigid means unable to move or remain stagnant.

Answer: kindly check explanation

Step-by-step explanation:

Given the following :

Amount saved by Jacob = $50

Amount spent at the movies = $15

Amount left after paying for bike repair = $0

Cost of bike repair :

$50 - $15 = $35

What integer represents Jacob’s savings?

Initial amount before any spending

Jacob's saving = +$50

2.What integer represents the change in Jacob’s savings after he spends money at the movies?

Saved amount - amount spent at the movies

$50 - $15 = $35

No number line is given

Answer:

-6

Step-by-step explanation:

First you need to substitute -1 in for x in -2x^2

This makes it (-2)(-1)^2

-2x^2 becomes -2 so this means that the equation is now

-2 + (-1) - 3

-2 + (-1) = -3

-3 - 3 = -6

Answer:

Area of larger rectangle = 1½ = 1.5 in²

Step-by-step explanation:

The section consists of 3 small squares that has an area = [tex] \frac{3}{16} in^2 [/tex].

Area of 3 small squares = [tex] \frac{3}{16} in^2 [/tex]

Area of 1 small square = [tex] \frac{3}{16} [/tex] ÷ 3

= [tex] \frac{3}{16} * \frac{1}{3} [/tex]

= [tex] \frac{3*1}{16*3} = \frac{1}{16} [/tex]

The larger rectangle has 24 small squares of equal sizes

Area of larger rectangle = area of 1 small square * 24

= [tex] \frac{1}{16} * 24 [/tex]

[tex] = \frac{24}{16} = \frac{3}{2} [/tex]

Area of larger rectangle = 1½ = 1.5 in²

Answer:

$16.81

Step-by-step explanation:

$50.00 -$8.50 - $13.99 - $6.50 = $21.01

$21.01 * 0.20 = $4.20

$21.01 - $4.20 = $16.81

Answer: 9

Step-by-step explanation: on a number line -9 is before 0 9 is after 0 , and any number to the right of a number is greater.

Answer:

x + 4

Step-by-step explanation:

Area of rectangle= length × breadth

In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12

This means that;

5x2 + 23x + 12 = 5x + 3 (b)

Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3

To get the other length, we can factorize the algebraic expression;

5x2 + 23x + 12

Product: 60x^2 (20x × 3x)

Sum: +23x (20x + 3x)

Hence;

= 5x^2 + 20x + 3x + 12

Next, we find factors;

5x (x+4) + 3 (x+4)

Therefore, the factors are (5x + 3) and (x +4)

This means that the other length is (x +4)

Answer:

The amount that should be written on the check is $7920

Step-by-step explanation:

The explanation of the question is given as:

1/10 = 1% discount to be given if paid within 10 days

n/15 = full amount to be paid within 15 days.

From the question, we can see that:

If the check for the invoice is given on December 8th, it is still within the discount time of 10 days.

Discount amount = $8000 × 1%

= $80

$8000 - $80

= $7920

Hence, the amount that should be written on the check is $7920
