Answer:

y = -1

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept.

First, find the slope by doing change in y / change in x:

-1 - (-1) / 8 - 4  = 0 / 4 = 0

this means that m = 0, so the equation so far is y = 0x + b or y = b

Then, you need to find what b is and since you know x = 8 and y = -1 is a solution, you can plug that into the equation:

-1 = 0 * 8 + b

-1 = b

This means that b = -1 and the equation would be y = -1

Answer:

y=-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-1))/(4-8)

m=(-1+1)/-4=0/-4=0

slope is 0

y-y1=m(x-x1)

y-(-1)=0(x-8)

y+1=0

y=0-1=-1

y=-1

Answer:

6x + 4, 46

Step-by-step explanation:

Linear expression - (x +4) + (x +4) = 2x +8

2x -2) + (2x-2) = 4x -4                             2x+8 +4x -4 = 6x + 4

6 * 7 = 42

42 + 4 = 46

The linear expression should be 6x + 4.

And, the perimeter is 46.

Given that,

Based on the above information, the calculation is as follows:

(x +4) + (x +4) = 2x +8

(2x -2) + (2x-2) = 4x -4        

Now

2x+8 +4x -4

= 6x + 4

The perimeter should be

= 6(7) + 4

= 42 + 4

= 46

Answer:

C) - 7/3

Step-by-step explanation:

Slope is rise over run, rise/run, and your line means your slope will be negative. So, you will first count straigt down from your firt point until you reach the line of the second point, which is 7. Next, you would count/run to the point, which is 3. Rise/run = -7/3. I hope this helps :)

Answer: C -7/3

Step-by-step explanation: Slope is rise over run, rise/run, and your line means your slope will be negative. So, you will first count straigt down from your firt point until you reach the line of the second point, which is 7. Next, you would count/run to the point, which is 3. Rise/run = -7/3.

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v=[tex]9\frac{9}{10}km/h[/tex]

Speed of object, v=[tex]9+0.9=9.9km/h[/tex]

Distance travel by object, s=[tex]5\frac{1}{10}km[/tex]

Distance travel by object, s=[tex]5+0.1=5.1km[/tex]

We have to find the time taken by object to travel 5 1/10 km.

We know that

[tex]Time=\frac{Distance}{speed}[/tex]

Using the formula

Time taken by object to travel 5.1 km =[tex]\frac{5.1}{9.9} hr[/tex]

Time taken by object to travel 5.1 km=0.52 hr

Answer:

C. There is no solution.

Step-by-step explanation:

First, multiply what in the parentheses by what's outside of them.

[tex]2(x - 3) = 2x + 5 ↴[/tex]

[tex]2x - 6 = 2x + 5 [/tex]

Then seperate variables from nonvariables. After subtracting [tex]2x[/tex] from the right and left side, the equation becomes this:

[tex] - 6 = 5[/tex]

This equation has no solutions because this is an inequality.

Answer: 91.65 ft

Step-by-step explanation:

(200*200) + (x) = 220*220

40000 + x = 48400

48400 - 40000 = x^2

8400 = x^2

91.65 = x

Answer:

2. I assume you're working on 1 so I skipped it. 2 would be 16000 yearly. 300 a week would equal 15,000 a year so its less

There are 52 weeks in a year which is how I got that number^

3. With the job he has he gets 21,548.8 per year(11.20 × 37 = 414.4 x 52 = 21,548.8). With the advertised job he would would get 21,150 yearly. 21000 + 5% of 3000 which would be his commission. so stick with his current job

4. (£9.40 x 35 hours = £329) (£329 x 52 weeks = £17,108). (3 extra hours per week x 52 weeks = £156) (£17,108 + £156 = £17,264) That is her total

Answer:

This is by far the easiest question ever...Can you actually read and put effort into it before looking up all your answers next time? It literally says there are 16 CATS and 14 DOGS in a SHELTER. Its not A, because it did not mention rabbits. Its not C because it did not mention too much about cats, and it said dogs and cats not cats and cats. And its not D because we aint talking about a neighborhood. So..it is B. Easy, peasy, lemon squeezy!
