Find The Equation Of The Line PLEASE HELP

Answers

Answer 1
Y=-3x+7..................
Answer 2

Answer:

y = -3x +7

Step-by-step explanation:

The equation for a line is: y = mx + b

m = slope

x = the x-value

y = the y-value

b = the y-intercept

Since the y-intercept is 7, we know the first part of the equation is: y = mx +7

Also, since the line is decreasing from right to left, m is going to be negative. A way to calculate the m is rise/run. Count how many blocks it is going horizontally (run)and how many blocks it is increasing/decreasing when going to the right (rise). Then divided the "rise" over "run". Another way is to choose two points. Now use the equation y1-y2/x1-x2,

or  y2-y1/x2-x1. I am going to show using the equation.

My two points are (0,7) and (2,1)

change in y (rise):7-1 = 6

change in x (run): 0-2 = -2

6/-2 = -3. Your slope is -3. Now lets put it all together.

y = -3x +7

You can see that for every square moved to the right ONCE the y value is decreasing by 3 each time.

which expression is equivalent to 8/9 divided by 3/4

Answers

Answer: 32/27 Equation: 8/9 x 4/3


Steps:

For dividing fractions remember the phrase “keep, change, change”

So keep the first fraction, change the division sign to a multiplication sign, and change the second fraction to its reciprocal.

8/9 x 4/3

Multiply the numerators together. Next, multiply the denominators together.

8 x 4 = 32
9 x 3 = 27

Answers

Answer:

Just interest is $187.50

Total is $2,687.50

Step-by-step explanation:

1. Determine what 7.5% of $2,500 is:

0.075 × 2,500 = 187.5

2. Add the interest (187.5) to the amount invested:

2,500 + 187.5 = 2,687.5

Answer:

375 interest, 2875 total

Step-by-step explanation:

I - ?

P - 2,500

R - .075

T - 2

2,500 x .075 = 187.5

187.5 x 2 = 375

375 + 2,500 = 2,875

What is a quadratic polynomial?

"It is a polynomial with degree 2."

What is synthetic division?

"It is defined as a way of dividing one polynomial by another polynomial of first degree."

For given question,

We have been given a quadratic polynomial [tex]F(x)=4x^{2} -17x-15[/tex]

We can factorize above quadratic polynomial as,

[tex]F(x)\\=4x^{2} -17x-15\\=4x^{2} -20x+3x-15\\=4x(x-5)+3(x-5)\\=(x-5)(4x+3)[/tex]

This means the factors of [tex]4x^{2} -17x-15[/tex] are (x - 5) (4x + 3)

And the roots of the polynomial would be,

[tex]\Rightarrow F(x)=0\\\Rightarrow 4x^{2} -17x-15=0\\\Rightarrow (x-5)(4x+3)=0\\\Rightarrow x-5=0~~,~~4x+3=0\\\Rightarrow x=5~~,~~x=-\frac{3}{4}[/tex]

This means, the roots of [tex]4x^{2} -17x-15[/tex] are 5 and [tex]\frac{-3}{4}[/tex]

Therefore, the correct statements about given synthetic division are C, D, and F

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.

Dylan opened a credit card account with $575.00 of available credit. Now that he has made some purchases, Dylan's account only has $465.75 of available credit. What is the percentage decrease of the amount of available credit in Dylan's account?
A.
14%
B.
81%
C.
19%
D.
23%

Answers

Answer:

C.) 19% decrese

Step-by-step explanation:

575.00 - 465.75 = 109.25

109.25/575.00 = 0.19

0.19 = 19%

575.00 - 465.75 = 109.25

109.25/575.00 = 0.19 = 19%

Therefore, the percentage decrease of the amount of available credit in Dylan's account is 19%.

Find the length of BC.

Answers

Answer:

BC = 8

Step-by-step explanation:

AB + BC = AC

4x + 8 + 3x - 4 = 32

7x + 4 = 32

7x = 32 - 4

7x = 28

x = 28/7

x = 4

BC = 3x - 4 = 3*4 - 4 = 12 - 4 = 8

Answer:

B) 8

Step-by-step explanation:

The Segment Addition Postulate basically states that the sum of the segments of a line will equal the length of the entire line.

Thus, AB+BC=AC, and we can substitute:

AB+BC=AC

(4x+8)+(3x-4)=32

4x+8+3x-4=32

7x+4=32

7x=28

x=4

Now that we have x, we can plug it in for segment BC:

BC=3x-4

3(4)-4

12-4

8

Therefore, choice B is correct

Several friends went to the movie. The tickets cost $24.50 and the refreshments for each friend were $2.50 and $4.85 each. The total was $83.30. Solve for x, the number of friends. $2.50x + $4.85x + $24.50 = $83.30

Answers

Answer:

x = 8

Step-by-step explanation:

Let there are x friends.

The tickets cost $24.50 and the refreshments for each friend were $2.50 and $4.85 each.

Total cost = $83.30

We need to solve for x. The equation for the scenario is given by :

$2.50x + $4.85x + $24.50 = $83.30

Taking like terms together

$2.50x + $4.85x = $83.30-$24.50

7.35 x = 58.8

x = 8

So, there are 8 friends.

The population of a town is 9,000, and it grows at a rate of 4.6% per year. What will the population be in 10 years ?

Answers

Answer:

13410

Step-by-step explanation:

So, first we find 4.6% of 9000

9000 x .046 = 414

Then we multiply the 414 by 10 because they gain 414 people every year and we need to find how many people after 10 years

414 x 10 = 4140

now add 4140 and 9000
