Answer:

y = 2x - 25

Step-by-step explanation:

First find the gradient, we can see it goes through (30,35) and 35,45), and since gradient is found by 'change in y / change in x' we can do: (45-35) / (35-30) = 10/5 = 2

So we know we are looking for an equation with 2x in it.

We have two options: y = 2x - 25 and y = 2x - 75.

Plug in one of the points and see which of the equations works.

Replacing y with 35 and x with 30 in the first equation we have: 35 = 2(30) - 25 = 60 - 25 = 35, this is indeed true.

However if we did the same with the second equation: 35 = 2(30)-75 = 60 - 75 = -15, this is false since 35 does not equal -15, so it can't be the second equation.

In conclusion it must be y = 2x - 25

Midpoint of the segment between the points (−5,13) and (6,4)

Leokris [45]

Answer: $(0.5,8.5)$

Step-by-step explanation:

We need to use the following formula to find the Midpoint "M":

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Given the points (-5,13) and (6,4) can identify that:

$x_1=-5\\x_2=6\\\\y_1=13\\y_2=4$

The final step is to substitute values into the formula.

Therefore, the midpoint of the segment between the points (-5,13) and (6,4) is:

$M=(\frac{-5+6}{2},\frac{13+4}{2})\\\\M=(\frac{1}{2},\frac{17}{2})\\\\M=(0.5,8.5)$

$3-2i/5+i$

$\frac{3*5+(-2)*1)+(-2*5-3*1)i}{5^2+1^2}$

$\frac{13-13i}{26}=\frac{1-i}{2}$

$=\frac{1}{2}-\frac{1}{2}i$

Hope this helps!

What is the percentage change for 60 to 35

Reil [10]

Let x represent the percentage change. The percentage change is a factor that the original number is multiplied to get the new number.

60*x = 35
x = 35/65 = 0.53846 = 53.846%
