Find three solutions for y=-2x-1

Mathematics
2 answers:
Pani-rosa [81]3 years ago

Answer:

(1, -3)

(2, -5)

(3, -7)

Step-by-step explanation:

Randomly choose three values for "x". Substitute each of them separately into the formula to find the "y". Then write the solution as an ordered pair (x, y).

I will choose x=1, x=2 and x=3.

When x=1:

y = -2x - 1

y = -2(1) - 1

y = -2 - 1

y = -3

(1, -3)

When x=2:

y = -2x - 1

y = -2(2) - 1

y = -4 - 1

y = -5

(2 , -5)

When x=3:

y = -2x - 1

y = -2(3) - 1

y = -6 - 1

y = -7

(3, -7)

(1,-3), (2,-5), and (3,-7)

An easy way to find this is set you a definite y value. So try -3 as the value for y. Solve for x as normal so -3=-2x-1. Add 1 on both sides to get -2=-2x. Divide on both sides by -2 and get 1=x. Since the slope is -2 you keep subtracting -2 from -3 and you’ll get -5 when x=2 and so on.

Answer:

median

Step-by-step explanation:

The first step is to sort the numbers from largest to smallest (you could go the other way as well).

60 52 48 44 20 16 12

The median is the middle number 44 in this case. The median has 3 numbers on its left and 3 on its right (in this case). 44 has 60 52 48 or its left and 20 16 and 12 on its right.

The mean is the average. We'll call it the new average

The mean is 60 + 52 + 48 + 44 + 20 + 16 + 12 = 252

The new mean is 252 / 7 = 36

=====================

The old median is the average between the middle 2 numbers (before you added 60 you had 6 numbers)

52 + 48 + 44 + 20 + 16 + 12 = the average of 44 + 20 which 64/2 = 32

The old mean was (52 + 48 + 44 + 20 + 16 + 12)/6 = 32.

=======================

The median increased from 44 to 32 = 12

The mean went from 32 to 36 which is 4

Answer: the median increased more

Help quick please with explain
Paul [167]

Answer:

20= v+9+( -16 )

20= v-( 7 )

27= v

Step-by-step explanation:

Adding a negative is the sane as subtracting. Add like terms. Add 7 to both sides. 27= v

B) 25% of the people surveyed preferred reading a book.

Explanation) You have to add up how many males and females rather
                      to read a book.  It's .10 + .15 =  25%.

C) 70 females were surveyed out of 200 people. 

Explanation)  Add up .15 + .5 + .15 to get .35.  Put .35 multiplied by 200 to                            get 70.

Billy is hiking in Colorado. He walks eastward four miles, then turns $60$ degrees northward and walks six miles. How far is he
nikklg [1K]

He is  2√19 miles far way from starting point.

Suppose Billy starts at point A, turns at point B, and ends at point D, as shown below.

If Billy turns 60◦ northward and walks six miles, then we can draw a 30 − 60 − 90 triangle whose hypotenuse is 6 miles

It follows that Billy traveled 6/2 = 3 miles eastward during these 6 miles, and that he traveled 3√3 miles northward during these 6 miles. In total, Billy traveled 4 + 3 = 7 miles  eastward and 3√ 3 miles northward.

By the Pythagorean Theorem, the distance from his starting point is q:

(7)2 + (3√3)2

=√49 + 27

= √76

= 2√19 .
