Find the slope ......

Answers

The slope for this problem is -4/3.

Step-by-step explanation:

To find the slope, we can look at it as Rise/Run. The rise is how many units up (+) a point is or how many units down (-) a point is from the starting point. The rise is how many units to the left or right a point is from the starting point.

Now that we understand Rise/Run, we can find the slope. If we go from the highest point, or the point farthest to the left in the picture shown, we can see that we need to go four units down to get to the same level as the next point, so we would be moving -4 units away from the point. We can also see the second point is 3 units to left.

With this information, we can now figure out that the slope is -4/3.

Don't hesitate to ask any questions.

Answer:

m =rise/ran=y2-y1/x2-x1

m=slope

(x1, y1)=coordinates of first point in the line

(x2, y2)=coordinates of second point in the line

Step-by-step explanation:

x - 5y - 25 = 0
x + 5y - 25 = 0

Answers

Answer:

x + 5y - 25 = 0

Step-by-step explanation:

Equation of line in slope intercept form is given as:

[tex]y = mx + b \\ \\ plug \: m = - \frac{1}{5} \: \: and \: \: b = 5 \\ \\ y = - \frac{1}{5} x + 5 \\ \\ 5y = - x + 25 \\ \\ x + 5y - 25 = 0[/tex]

A phone company offers two monthly plans. Plan A costs $8 plus an additional $0.09 for each minute of calls. plan B cost $16 plus an additional $0.07 for each minute of calls.

a. For what amount of calling do the two plans cost the same? minutes

b. What is the cost when the two plans cost the same? $​

Answers

Answer: 72

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72

280 minutes and cost $72 each

You started the trail with 1400lbs. of food. You now have 1182lbs. of food. What percentage of your starting amount do you have left?

Answers

Answer:

84.5%

Step-by-step explanation:

1400 - 1182 = 218 You are less 218 lbs. of food.

218 ÷ 1400 = 15.5% You are less 15.5% lbs. of food.

100% - 15.5% = 84.5% You have 84.5% lbs if food left.

Derrick needs to sell a minimum of 100 orders each month to make it into the sales winners circle. He has already sold 45 orders this month. He still needs to sell s more orders. Which inequality can be used to find the possible values for s? s−45>100
s−45<100 s+45≤100 s+45≥100

Answers

Answer:

s+45≥100

Step-by-step explanation:

"A minimum of" means either the same amount or more. So, the total amount he sells (s + 45) needs to be greater than or equal to 100.

what is 3/4b>15 solution

Answers

The solution set of the given inequality is  {b| b > 20}.

How to solve the inequality?

Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.

And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:

(4/3)*(3/4)*b > 15*(4/3)

b > 20

Then the solution set can be written as {b| b > 20}

That is the set of all values larger than 20.
