Answer:

I don't have Idea

Answer:

x = 0, y= -16

Step-by-step explanation:

Okay, we can use elimination to do this. Add the two equations together to get rid of one of the variables. 7x and -7x cancel each other out, so we are left with y+y= -32. If y+y is -32, then y= -16. Let's plug that back one of the equations. I'll choose the first equation. 7x +(-16) = -16. We can simplify that to 7x - 16= -16. Okay, we add 16 to both sides which gets us 7x=0. From this, we can infer that x=0 because 0x7=0. Now we have the answer, x=0, and y= -16. I hope this helps!

Answer:

a.

65,000

Step-by-step explanation:

There are 65000 possibilities of 4 character-password

A password is a security code that is used for verifying identities

The password has 4 characters.

The password must begin and end with a letter.

So the selections are:

First = 26

Last = 25

The other selections are:

Second = 10 digits

Third = 10 digits

So, the number of password is:

Password = 26 * 10 * 10 * 25

Evaluate

Password = 65000

Hence, there are 65000 possibilities of 4 character-password

Answer:

H

Step-by-step explanation:

The fine for speeding is $17 mile per hour. Thus, for speeding for a total of x miles per hour above the posted speed limit of 30 mile per hour, there will be a fine of: 17(x - 30)

x in the equation is the speed of the driver and the negative sign in the equation shows that the driver was traveling at a total speed greater than the posted speed limit (thus, x - 30 is the speed above the posted speed limit in which the driver will be fined for)

Since the driver was fined $221, the equation becomes:

17(x - 30) = 221

divide both sides by 17

x - 30 = 221/17

x - 30 = 13

x = 13 + 30

x = 43

The driver was fined for travelling at a speed of 43 miles per hour which is 13 greater than the posted speed limit.

Step-by-step explanation:

It says she has a maximum, that means she cannot go pass the amount ($50)

It costs $7 to get in so you have to take that from what she has ($50)

Answer:

y= -7x+7

Step-by-step explanation:

y= mx+b

y= slope x+ y intercept

The equation of the line having the slope -7 and y-intercept  is 7 is: y = -7x + 7

A straight line's equation is a relationship between its x and y coordinates, and it is written as y = mx + c, where m is the line's slope and c is its y-intercept.

We are given that the slope m is -7,

and the line crosses the y-axis at 7.

so the value of c = 7

Therefore, we can substitute these values into the slope-intercept form to get:

y = -7x + 7

So the equation of the line is y = -7x + 7.

the slope goes up 11 and over 2 and the line crosses the y-axis at 29 so thats the y-intercept

Answer:

a. ║ x - 23 ║ ≤ 6 b.  17 ≤ x ≤ 29

Step-by-step explanation:

a. Let x be the length of the wall. Since the length of the wall is half the length of the drive way with an absolute deviation of 6 at most, since the drive way is 46 foot long, half of it is 46/2 = 23.

So, 23 ± 6 ≤ x or x - 23 ≤ ±6 or ║ x - 23 ║ ≤ 6

b. Solving the absolute value inequality,

-(x - 23) ≤ 6 and x - 23 ≤ 6

x - 23 ≥ 6 and x - 23 ≤ 6

x ≥ 23 - 6 and x ≤ 23 + 6

x ≥ 17 and x ≤ 29

So 17 ≤ x ≤ 29

Answer:

Step-by-step explanation:

use Pythagorean theorem a² + b² = c²

where a = 8

           b = 15

           c = s (which is unknown)

plugin values into the formula:

a² + b² = c²

8² + 15² = s²

s = √(64 + 225)

s = √289

s = 17

The solution is.  the equation of the line perpendicular to the line 2x - 5y = 7 and passes through the point (2, -3) in slope-intercept form with no spaces is : y = -5/2x + 2.

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

here, we have,

given that,

the line is:

5y = 2x - 7

y = 2/5x - 7/5

Slope = -5/2 (perpendicular)

Slope int. = y = mx + b

Y = -5/2x + b

-3 = -5/2(2) + b

-3 = -5 + b, b = 2

Solution: y = -5/2x + 2

Hence, The solution is.  the equation of the line perpendicular to the line 2x - 5y = 7 and passes through the point (2, -3) in slope-intercept form with no spaces is : y = -5/2x + 2.

Answer:

3 batches of cookies

Step-by-step explanation:

Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.

How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?

We can calculate the batches using either cups of flour or number of teaspoons.

For flour

5 cups of flour = 1 batch of cookies

15 cups of flour = x

Cross Multiply

5x = 15 × 1

x = 15/5

x = 3 batches of cookies

For teaspoons of vanilla

2 teaspoons of vanilla = 1 batch of cookies

6 teaspoons of vanilla = x

Cross Multiply

2x = 6 × 1

x = 6/2

x = 3 batches of cookies.

Hence: you can make 3 batches of cookies with 15 cups of flour and 6 teaspoons of vanilla

Answer:

its b

Step-by-step explanation:

if negative 5 is an absolute value it becomes just a regular 5. Therefore it would be equivalent to -3+5. (sorry if I'm wrong)

d-13=5 is actually suppose to be solved liek this:

d - 13 = 5

   +13   +13

The absoulte value of 13 is 13, it is negative so you have to add 13 to get to 0 so it can be cancelled out.
