Which is the equation in Point-slope form of the line with a slope of 2 and passing thru the point (2,1)
KIM [24]

Answer:

y - 1 = 2(x - 2)

General Formulas and Concepts:

<u>Algebra I</u>

Point-Slope Form: y - y₁ = m(x - x₁)

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Slope <em>m</em> = 2

Point (2, 1)

<u>Step 2: Write Equation</u>

  1. Substitute in variables:                       y - 1 = 2(x - 2)

there is a beaker of 3.5% acid solution and a beaker of 6% acid solution in the science lab. Mr. Larson needs 200ml of 4.5% acid
disa [49]
Below are the choices:

A. 80 mL of the 3.5% solution and 120 mL of the 6% solution 

<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>

<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>

<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p. 

<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>

<span>3.5p + 6 - 6p = 4.5 </span>

<span>2.5p = 1.5 </span>

<span>p = 3/5 </span>

<span>3/5 * 200 = 120 </span>

<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>

Please answer correctly !!!!!!! Will mark Brianliest !!!!!!!!!!!

Answer:

x=-2\\x=2

(You only need to give one solution)

Step-by-step explanation:

We have the following equation

(x^2+1)^2-5x^2-5=0

First, we need to foil out the parenthesis

x^4+2x^2+1-5x^2-5=0

Now we can combine the like terms

x^4-3x^2-4=0

Now, we need to factor this equation.

To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.

The pair of numbers that would do this would be 1 and -4.

This means that our factored form would be

(x^2-4)(x^2+1)=0

As the first binomial is a difference of squares, it can be factored futher into

(x^2+1)(x+2)(x-2)=0

Now, we can get our solutions.

The first binomial will produce two complex (Not real) solutions.

x+2=0\\\\x=-2

x-2=0\\\\x=2

So our solutions to this equation are

x=-2\\x=2

B is the midpoint of A . If AB = x+5 and BC =2x-11, find the measure of AB
nignag [31]

If B is the midpoint of AC, then AB = BC.

We have AB = x + 5 and BC = 2x - 11.

Therefore we have the equation:

x + 5 = 2x - 11       <em>subtract 5 from both sides</em>

x = 2x - 16       <em>subtract 2x from both sides</em>

-x = -16      <em>change the signs</em>

x = 16

Put the value of x to the expression x + 5:

AB = 16 + 5 = 21

<h3>Answer: AB = 21</h3>
