Answer:

$25\:-\:5\:\cdot \:2^2\:+\:1 = 6$

Step-by-step explanation:

$25-5\cdot \:2^2+1$

Calculate exponents $2^2 : 4$

$=25-5\cdot \:4+1$

Multiply and divide (left to right) $5\cdot \:4 : 20$

$=25-20+1$

Add and subtract (left to right) $25-20+1 : 6$

$= 6$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you, have a good day! =)

frutty [35]

Answer:

$m=20n$

Step-by-step explanation:

Let

$A(5,100),B(10,200)$

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$slope=\frac{m2-m1}{n2-n1}$

substitute the values

$slope=\frac{200-100}{10-5}=20$

step 2

Find the equation of the line into slope-point

$m-m1=slope(n-n1)$

with the slope and the point A

$m-100=20(n-5)$

$m=20n-100+100$

$m=20n$

Please help i suck at these

vaieri [72.5K]

Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

<u>So the first option would be correct!</u>

Hope this helps!
