How do you write sentences 10+k=4K

Andrei [34K]

K added to 10 gives you 4 times the value of K.

If you wanted to solve the expression:

Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k

If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.

We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k

What is the first step in solving the quadratic equation -5x^2+8=133?

bezimeni [28]

Answer:

a) subtracting '8' on both sides, we get

- 5 x² + 8-8 = 133-8

- 5 x² = 125

b) The solution is x = 5 i

Step-by-step explanation:

Explanation:-

Step (i):-

Given quadratic equation - 5 x² + 8 = 133

subtracting '8' on both sides, we get

- 5 x² + 8-8 = 133-8

- 5 x² = 125

Step(ii):-

dividing '-5' on both sides, we get

$\frac{-5 x^2}{-5} = \frac{125}{-5}$

x² = -25

$x = \sqrt{-25}$

x = 5 i

Write a linear function that passes through (1,5) and (2,15)

Leokris [45]

Simple,

using $\frac{y1-y2}{x1-x2} =m (slope)$

find your slope...

$\frac{5-15}{1-2} = \frac{-10}{-1}=10$

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.
