  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra II</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (1, 7)

Point (-8, -5)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [DF]:                       \displaystyle d = \sqrt{(-8-1)^2+(-5-7)^2}
  2. (Parenthesis) Subtract:                          \displaystyle d = \sqrt{(-9)^2+(-12)^2}
  3. [√Radical] Exponents:                           \displaystyle d = \sqrt{81+144}
  4. [√Radical] Add:                                      \displaystyle d = \sqrt{225}
  5. [√Radical] Evaluate:                              \displaystyle d = 15

How to tell if its identifying functions is <br> a function or not
Svetach [21]

Answer:

Step-by-step explanation:

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

So, I need some help with these scatter plot questions. (basically free points because these might be easy for you!) (20 points)
nlexa [21]

Hello,

I have a graphing calculator so this will be easy for me to answer and explain how to figure these out. Here we go!

1. Well on a Ti - 84 plus calculator it says graph then you put in thee equations for each and C and D are already incorrect cause they go straight up and B is incorrect because it is a straight line on the top going straight. In this case your looking for a line that goes through the dots. And the answer would be A) Y = 1/2x + 7.

2. B) Then umber of accidents were reduced by 0.67 per month for every additional driver in the program.

3. Key: Y means yes N means no. Plot A had 1 disease present and 2 not present. Plot B has 3 diseases present and 1 disease not present.

4. Category A had 36 groups in group 1. and Category B had 12 groups in group 1. Easy!

Please mark Brainliest!

Hope I Helped!

Have a fantastic Day!

Which technique is most appropriate to use to solve each equation? Drag the name of the technique into the box to match each equ
NemiM [27]
For the first equation, the answer is C) completing the square.
For the second equation, the answer is B) zero product property.

For the first equation, we can easily complete the square by finding half of b and squaring it; then we can take the square root of both sides and solve the equation.

For the second equation, since it is already factored, we use the zero product property to solve it.
