Complete the equation of the line through (3,-1) and (4,7)

Answers

Answer 1
firstly , we must find the gradient.

gradient, m = y2 - y1 / x2 - x1

m = 7 - (-1) / 4 - 3
m = 8

a straight line is y=mx+c
thus, we have to find the c which is y-int by subs one of the coordinate to the equation.

y=mx + c
7=8(4) + c
c = -25

thus the equation is y = 8x - 25
Answer 2




The answer would be Y=8x-25

If y = kx, and x = 3 and y = 15, calculate k.

Answers

Answer:

k = 5

Step-by-step explanation:

Since the equation is y = kx and x equals 3 while y equals 15, in order to solve this equation we are going to have to substitute the variables with their answers:

x = 3

y = 15

15 = 3k

Now we divide 3 from both 3x and 15 to segregate the variable x:

15/3 = 3k/3

5 = k

Now to check our work we are going to substitute 5 for the variable k, 3 for the variable x and 15 for the variable y.

y = kx

15= (5)(3)

15 = 15

Tada, I hope this helps you!

Answer:

k=5

Step-by-step explanation:

y=kx     Also meaning   y = k times x

x=3      y=15      

y divided by x   = 15 divided by 3 = 5

k=5

Lets Check Our Work

y=kx

15=?3

? times 3 is 15  = 5

Over a one week period in the summer, the price of a gallon of gas increased from $2.35 to $2.82. By what percent did the price of gas increase over that week?

Answers

The price of gas increases from $2.35 to $2.82 or by $0.47 ($2.82 - $2.35 = $0.47).
The increase as a percentage of the original price is given by
($0.47/$2.35) x 100% = 20%

The answer is 20%
Hope this helps :)

The percentage increase from $2.35 to $2.82 over the week in summer is 20%

Given Data

Initial Value = $2.35

Final Value = $2.82

We know that the expression for Percentage increase is given as

% Increase = Increment/Initial Value *100

% Increase = 2.82-2.35/2/35 * 100

% Increase =0.47/2/2.35 * 100

% Increase =0.2* 100

% Increase = 20%

Hence the percentage increase is 20%

Okay so ur at a party and they have donuts, 5/25 of the donuts are eaten. What percent of them are left?

If it's not too much trouble could you explain how to solve it? If not I guess I'll live:(

Answers

Answer:

80%

Step-by-step explanation:

100%= 25/25. 1 donut = 5%. So you have 20 donuts left x 5.

Answer:

80% are left.

Step-by-step explanation:

So 100 donuts would be 100%. To get to 100 you need to multiply 25x4. Then you also need to multiply 5x4=20. Since it is the 5 that are eaten, you subtract 20 from 100 and get 80, so you are left with 80% of the donuts.

у = 3х
x = -2y + 70

Answers

the answer should be (10,30)

Answer:  (10,30)

Step-by-step explanation:

y = 3x  

x = -2y + 70  

Solve by using the substitution method. Substitute the value for x into the first equation and solve for y.

y = 3(-2y + 70)      Multiply it out

  y = -6y + 210            Add 6y to both sides

+6y    +6y

7y = 210

 y =  30  

Since y is equal to 30, input the value for y into the equation and solve for x.

30 = 3x    Divide both sides by 3

x = 10
