Step-by-step explanation:

Well its

y=mx+b

m is slope

B is y intercept

To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.

Slope Is just

(y2-y1) / (x2-x1)

Add (7х2 – 3x) + (5х – 6).

Masja [62]

Option C: The solution is $7x^{2} +2x-6$

Explanation:

The given expression is $(7x^{2} -3x)+(5x-6)$

We need to solution of the given expression.

The solution of the given expression can be determined by adding the two expressions.

Let us remove the parenthesis.

Thus, we have,

$7x^{2} -3x+5x-6$

Adding the like terms, we have,

$7x^{2} +2x-6$

Thus, the solution is $7x^{2} +2x-6$

Hence, Option C is the correct answer.

Drag each title to the correct box. Not all tiles will be used

mestny [16]

Answer:

4, 1, 6.

See explanation

Step-by-step explanation:

You are given the equation

$d=vt-\dfrac{1}{2}at^2$

First subtract $vt$ from both sides:

$d-vt--\dfrac{1}{2}at^2$

and multiply the equation by -1:

$vt-d=\dfrac{1}{2}at^2\ \ \ \ (1)$

Now multiply (1) by 2:

$2(vt-d)=at^2\ \ \ \ \ (2)$

At last, divide by $a$

$t^2=\dfrac{2(vt-d)}{a}\ \ \ \ \ (3)$
