Which equation in point-slope form describes the line that passes through the point (4,-5) and is perpendicular to
the line represented by
- 7x + 2y = 14?

Answers

9514 1404 393

Answer:

  D  y +5 = -2/7(x -4)

Step-by-step explanation:

The point-slope form is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

You're given (h, k) = (4, -5), so the equation will be of the form ...

  y +5 = m(x -4) . . . . for some slope m

This form eliminates the first two choices.

__

The slope of the given line is the coefficient of x when solved for y:

  2y = 7x +14

  y = 7/2x +7  . . . .  slope is 7/2

The perpendicular line will have a slope that is the opposite reciprocal of this, ...

  -2/7 . . . . slope of perpendicular line

This is the slope shown in choice D:

  y +5 = -2/7(x -4)

D

number 2 is c

number 1 is d?

Step-by-step explanation:

because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35  words 35m=w

for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer

Answer:

(For your second question.):

35w=m

Step-by-step explanation:

Why?

It states in the problem itself that miles types 35 words per minute.

"w" stands for words

'm' stands for minutes.

The constant rate relies on the clearest data after all. The equation itself is enough!

Remember: 1 min = 60 seconds.

On the morning of the sale, the store donated 50 pairs of shoes to a homeless shelter. Then they sold 64% of their remaining inventory during the sale. If the store had 288 pairs after the donation and the sale, how many pairs of shoes did they have at the start? how many shoes did they have at the start?

Answers

Answer:

850.

Step-by-step explanation:

Let the number at the start be x shoes. Then:

x - 50 - 0.64(x - 50) = 288

x - 0.64x - 50 + 32 = 288

0.36x = 288 + 50 - 32

0.36x = 306

x = 306/0.36 =  850.

Mrs. Curry own a hair salon. One day, she gave 12 haircuts. She eamed $19.95 for each and received an average tip of $2 for each
haircut.
Select the equation that would express the total amount that she eamed?
a. (19.95 x 12)2
c 19.95 + 2 + 12
b. (19.95 x 2) +12
d. 12(19.95 +2)

Answers

Answer:

Option d     12(19.95 + 2)

Step-by-step explanation:

The answer would be an option d, since we know that she gets paid $19.95 plus the $2 per haircut, and we know that she gave 12 haircuts there for we multiply the sum of $19.95 and $2 by 12, and that can be written down as...

12(19.95 + 2)

Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 10 5

Answers

Answer:

In bold below.

Step-by-step explanation:

a) 12 10 8 6 4

This is an arithmetic sequence with common difference -2.

nth term = a1 + (n - 1)d

= 12 + (n - 1)-2

= 12  -2n + 2

= -2n + 14.

b) 25 20 15 10 5

This is an arithmetic sequence with common difference -5.

nth term = a1 + (n - 1)d

= 25 + (n - 1)-5

= 25  - 5n + 5

= -5n + 30.

A coach buys a uniform and basketball for each of the 15 players on the team. Each
basketball cost $9.50. The coach spends a total of $450 for uniforms and basketballs.
What is the cost, in dollars, of each uniform?
$

Answers


Uniforms: $20.5

450 divided by 15 = 30
Each person on the basketball team got $30 worth of stuff.
If the basketball cost $9.50: 30-9.50=20.5
This means that each of the uniforms are $20.5

Answers

Combining like terms is key in this expression.


4p - 2/4 • 2p + 5/2 • 2/3

Change denominators to be the same.

(2/4)(3) = 6/12
(5/2)(6) = 30/12
(2/3)(4) = 8/12

Now combine these three fractions.


-6/12 + 30/12 • 8/12

24/12 • 8/12

Reduce these two for easier work.

2/1 • 2/3 = 4/3


Combine the terms with p variables.

4p • 2p = 8p^2


Final answer is;

8p^2 + 4/3

selected and not replaced. Then another letter will be selected. What is the probability of
Hormony selecting a C and then an E?

Answers

Answer:

3/56

Step-by-step explanation:

There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to [tex]\frac{1}{8}[/tex] times [tex]\frac{3}{7}[/tex], which is equal to [tex]\frac{3}{56}[/tex].

Maggie is trying to find the best deal to buy bags of potato chips. Option A: $0.90 for 9 bags of chips Option B: $0.84 for 7 bags of chips Option C: $1.50 for 5 bags of chips Which option is the better deal?
A
Option A
B
Option B
C
Option C

Answers

Answer:

The answer is option A. Since you would be paying 0.10 for each bag.

The solution is Option A.

The best deal for Maggie to buy the bag of potato chips would be 9 bags for $ 0.90 because each bag cost $ 0.10

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of each bag be represented as A

Now , the equation will be

a)

$0.90 for 9 bags of chips

The cost of 9 bags = $ 0.90

The cost of 1 bag A = The cost of 9 bags / 9

Substituting the values in the equation , we get

The cost of 1 bag A = 0.90 / 9

On simplifying the equation , we get

The cost of 1 bag A = $ 0.10

b)

$0.84 for 7 bags of chips

The cost of 7 bags = $ 0.84

The cost of 1 bag A = The cost of 7 bags / 7

Substituting the values in the equation , we get

The cost of 1 bag A = 0.84 / 7

On simplifying the equation , we get

The cost of 1 bag A = $ 0.12

c)

$1.50 for 5 bags of chips

The cost of 5 bags = $ 1.50

The cost of 1 bag A = The cost of 5 bags / 5

Substituting the values in the equation , we get

The cost of 1 bag A = 1.50 / 5

On simplifying the equation , we get

The cost of 1 bag A = $ 0.30

Therefore , the 0.10 < 0.12 < 0.30

Hence , the cost of $0.90 for 9 bags of chips is the best deal

Answers

6 minutes per window. Multiply 3(60) and then divide by the number of windows (30)

Answer:

A. 6 minutes

Step-by-step explanation:

6 minutes is 1/10 of an hour.

60 minutes is 1 hour.

5,400 minutes is 90 hours.

3 hours is 180 minutes. You can solve this as a proportion:

[tex]\frac{180}{30} =\frac{x}{1}[/tex]

Cross multiply to get 30x = 180. x = 6.
