Find the slope and y-intercept of the following equation: Y = ¾ x - ½

Your question has been heard loud and clear.

3[-x + (2 x + 1)] = X – 1

= 3[-x+2x+1]= x-1

= 3 [ x+1] = x-1

= 3x+ 3 = x-1

3x-x = -3-1

2x= -4

so , x = -4/2 = -2

Therefore , x = -2

Thank you

Answer:

3x+3=x-1

3x-x=-1-3

2x=-4

x=-2

Answer:

He had to have walked 5 dogs and done one survey

Step-by-step explanation:

Given :

The temperature of a pot of water is 62 F .

The temperature increases  by 20 F per minute when being heated .

To Find :

Write an equation to represent  the linear relationship.

Solution :

Here , the temperature is increasing directly with the time .

Therefore , it is a linear equation .

Let temperature varies with as :

T = at+b   .... equation 1 .

( Here , a and b are constants )

Now , at t= 0 min .

[tex]T = 62 =a\times 0 + b[/tex]

[tex]b=62[/tex]    

Now , after 1 min temperature will be , T = 62 +20 =82 F

[tex]T = 82 = a\times 1+62\\a=20[/tex]

Putting value of a ans b in equation 1 , we get :

[tex]T=20t+62\ F[/tex]

Hence , this is the required relation .

That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.

If you had 2a+3a, then it would simplify to 5a

Similarly, 2b+3b = 5b

Or you could have 2ab+3ab = 5ab

The key is that the variable portions must match up to be able to add them.

Answer:y=10x-1

Step-by-step explanation:

Answer:

y=2x-58

Explanation:

In order to write our point-slope formula (y=mx+C format), we first need to figure out the slope (m). To figure out the slope, we divide the change in y by the change in x between the two points (rise/run). The rise is 30 (2-(-28)) and the run is 15 (30-15). Therefore the slope is 2 (30/15)

This gives us:

y=2x + c

Now to figure out C (which will be the y-intercept of the graph) we substitute in the values from one of the points. So our x=30 and our y=2:

2=2(30) + c

2=60+c

2-60=c

-58=c

So now we know that our C (constant) is - 58.

Hence our point-slope formula is:

y=2x-58

Which you can test with the other point:

-28=2(15) - 58

Hope this helped!

Answer:

y-2=2

Step-by-step explanation:

Answer:

Domain : 0° < x <90°

Range: 90° < y < 180°.

Step-by-step explanation:

When we have a function:

f(x) = y

the domain is the set of the possible values of x, and the range is the set of the possible values of y.

In this case we have:

x + y = 180°

such that x < y

Let's analyze the possible values of x.

The smallest possible value of x must be larger than 0°, as we are workin with suplementary angles.

Knowing this, we can find the maximum value for y:

0° + y = 180°

y = 180° is the maximum of the range.

Then we have:

0° < x

y < 180°

To find the other extreme, we can use the other relation:

x < y.

Then, we can impose that x = y (this value will not be either in the range nor the domain)

if x = y then:

x + y = x + x = 180

2*x = 180

x = 90°

This will be the maximum of the domain and the minimum of the range.

Then we have that the domain is:

0° < x <90°

And the range is:

90° < y < 180°.

Answer:

The answer is "-9 feet and Ground-level".

Step-by-step explanation:

Given value:

total length or distance from apple tree = 9 feets

In the calculation of the distance between both the ground and the tree will be the same.  

If he gets higher 9 feet, he will go back to the ground 9 feet, in this case, the represents ground  value is equal to 0.

In the calculation of absolute values it value is opposite but the same.

Answer:

17

Step-by-step explanation:

Answer: She bought 17 books

Step-by-step explanation:

Add $6 to the amount that she paid to find out how much money she would have paid.

45 + 6 = 51  so she would have paid $51  

Now divide 51 by 3 to find out how many books she bought.

51 / 3 = 17  

So because of the discount, she paid $45 for 17 books.

-14÷(-4.48)

14÷(4.48)

divide that you will get 3.125

25/8, 3 1/8

is its alternative form.

Answer:

Step-by-step explanation:

If Point P is the interior of ∠OZQ, then ∠ O Z P +∠ P Z Q = ∠ O Z Q

Given  O Z Q = 125 and m ∠ O Z P =62, to get  ∠ P Z Q, substitute the given angles into the formula above as shown;

∠ O Z P +∠ P Z Q = ∠ O Z Q

62 +∠ P Z Q = 125

subtract 62 from both sides

62 +∠ P Z Q - 62= 125 - 62

∠ P Z Q  = 63°

Hence the angle ∠ P Z Q  is 63°

Answer:

4.  770 people

5.  16 min

6.  10.8 laps

Step-by-step explanation:

4.  330 people   =       x        

      3 hours               7 hours

just cross multiply:

3x = 330(7)

x = 2310 / 3

x = 770 people

5.   15 laps =   30 laps

        8                x

just cross multiply:

15x = 30(8)

x = 240 / 15

x = 16 mins

6.   18 laps =       x      

        10              6

just cross multiply:

10x = 18(6)

x = 108 / 10

x = 10.8 laps

Answer:

Answer:

[tex]KM = 4[/tex]

Step-by-step explanation:

Given

[tex]LM = 3x + 3[/tex]

[tex]KM = 5x + 4[/tex]

[tex]KL = 5x + 1[/tex]

Required

Determine KM

The relationship between the given parameters is:

[tex]KM = KL + LM[/tex]

Substitute the values of KM, KL and LM

[tex]5x + 4 = 5x + 1 + 3x + 3[/tex]

Collect Like Terms

[tex]5x - 5x - 3x = 1 + 3 - 4[/tex]

[tex]-3x = 0[/tex]

Divide through by -3

[tex]x = 0[/tex]

Substitute 0 for x in [tex]KM = 5x + 4[/tex]

[tex]KM = 5 *0 + 4[/tex]

[tex]KM = 0 + 4[/tex]

[tex]KM = 4[/tex]

Answer:

He can buy 22 lunches.

Step-by-step explanation:

To find how many he can buy if he had $100, we must divide the cost of one lunch to the amount of money he has.

(Round to the nearest whole number to get the exact amount of lunches that he can buy.)

1 lunch = $4.50

So:

=$100 ÷ $4.50 = 22.222....

=22.222.... = 22

Hope this helps! I'm sorry if it's wrong.

Answer:

is A

Step-by-step explanation:

y = 3 is written in slope-intercept form (y = mx + b).

The only variable we are given in this equation is "b" which is "3".

We don't have a slope variable at all which means the slope is 0 or undefined.

The y-intercept is 3.

Best of Luck!
